Using a 4K TV as a Desktop Monitor

I implemented this idea over a year ago. But I found a better solution for cheaper. I bought the Hisense H8C 55" 4k UHD. I found it on Amazon on sale for an amazingly low price of $400. And unlike the article's writer, I was almost obsessed about the amount of USB and HDMI ports, and how they were rated. This tv gave me everything I needed in one giant package, and it has worked out perfectly ever since. After my initial tweaking, the picture is excellent, the movements are smooth and fluent and I use it with a gaming laptop, set to allow the lid to be closed. I have a logitech K800 wireless illuminated keyboard, and a logitech wireless M70 trackball mouse. Both of those mean I can take the keyboard and mouse across the room, sit on the couch and use them at remote controls for the computer as well as the tv. Since I am a cord cutter, and watch most of my tv online, it all works about perfectly well. I have had no problems with burnin or input lag, as there are settings to control them.
 
I have a Sony 23in 1080pm TV now as a screen also. I have been using t for some time and wanted to upgrade to a curved screen myself. But I wanted to take advantage of the AMD Freesinc. So I wonder if there is any difference there in 4k with freesinc(if any) on a monitor vs a 4k TV.
 
Burn-in huh? Interesting. I thought those days were behind us but I guess not. The more things change the more things stay the same lol.
I've been using a Samsung Ultra HD 4K 40 inch flat screen for several years now. Usa a screensaver or let the monitor (TV) resort to black when you're not using the pc and no worries about burn in problems.
 
I'm using my 55 "4K HDR 1000 2016 Samung UN 55KS8000 TV as an occasional windows 10 extended desktop at 2160p out from this d/GPU nude HP pavilion clean installed windows 10 on SSD - PC ,only a Haswell core i5 Intel IGPU .

No gaming in here thats on a game biuld PC and modified G27 wheel & pedals in the game /2.1 (music large) style room .


the long part:

Imagine we have now up to 10 bit 1B colors 4K-8K HDR content on the web , 4K HDR You Tube the new Smung here can get in the Smart TV Y.T.app and a PC can not. only 4K SDR .

Imagine what a 1474 NIT 10 bit 7000:1 contrast panel can do for color , shadow brightness details ,gradients ,peaks ,nuances & highlights and luma peaks at all intensities and gradations and everything from A to Z ,4:4:4 and RGBs and beyond that too and tone mapping to 6000 NITS .> HDR TV can even do that yet only to 4000 NIT .

Let me just say its amazing watching movies and TV often now and moreover those I have seen on lesser panels including my 3.5 X dimmer 2015 4K HDR Sony 55X850C TV.

I upgraded from that Sony in here from and put that in the family cinema room to replace a range topping 2014 1080p Samsung 64f8500 plasma in there .

Nether TV is anywhere near this 4K HDR 1000 2016 Samung UN 55KS8000

(* Samsung UN55KS800D in Costco black chrome here ) & panel code binned for a Samung Direct FA01 panel, Its an ultra black,ultra clear Samsung moth eye 4K HDR 1474 NIT 7000:1 contrast active edge dimming 55" 4K HDR TV panel and thats a lofty LCD TV tier in 2017 still @ this panel & TV level .

High bit rate hires up to 4K HDR eye candy I have on my media drives is stunning more so than it was on the Sony I moved to the family cinema .

Setting OLED aside Today in 2017 you will a spendy Sony 9ZD LED/LCD FALD TV or the well regarded active edge dimming Sony X930E LED/LCD or an active edge dimming Samsung Q9 maybe Q8 QLED LCD model ,lesser TV's need not apply at all .


Setting aside OLED one may have difficulty imagining all that on a display panel unless you have a similar display capability ,these can toast your retinas with superlative eye candies like maybe 4 2017 TV models and maybe a lofty HDR PC panel

That said for lt. office and web general I prefer this 27" PC panel and I can switch or cast videos over into the TV at up tp 2160 p or as an 2160p W10 extended desktop and up to 4K HDR you tube

I can get the web up to 4K HDR Youtube and same for IPTV and everything else including a plausible chrome web browser in the TV without this PC .

Free 4K up to 4K HDR eye candy and TV factory demos to download and with a Youtube downloader /converter you can get up to 4K HDR there too

ppfftt outside of *unlikely screen image retention burn in on an LCD TV panel ,

Panel break in is myth on LCD panels (just like solid state electronics & electrical/.data cables of any kind ) LCD panels are passive displays and filter light spectrum or min. black is blocking light spectrum on an LCD panel they are not emission panels .
 
I've been using a Samsung Ultra HD 4K 40 inch flat screen for several years now. Usa a screensaver or let the monitor (TV) resort to black when you're not using the pc and no worries about burn in problems.

Although LCD image retention burn is highly unlikely on a passive light spectrum filter (light block at min. black) LCD panel ,I can see that for prolonged idle periods at power [on]

My 55" 2016 4K HDR 1000 Samsung 55 KS 8000 TV does a white orbiting Samsung SUHD logo screensaver automatically on at least the PC input (after a decent while ) . I believe you can set the time interval for it to come on .

again,
That said for lt. office and web general I prefer this 27" PC panel on the articulating gas charged monitor arm and I can switch or cast videos over into the TV at up to 2160 p or @ HDMI a 2160p W10 extended desktop and up to 4K HDR Youtube and IPTV including a plausible chrome web browser without the PC! .

The Samsung 4K HDR 1000 KS8000 TV is on a full motion wall mount in here in the man cave with a spendy 5.1 .

I don't buy anthing but decent Samsung or Sony 55" + 4K HDR now and once an OK 42" 1080p LG for a bdrm. in 2013 (not my bdrm ☺) .

I don't mes with all the second and third thier tier Rubbish below LG, Sony and Samsung and never the second tier cheap ones there now for instance

FWIE they are second tier at Hisense and Vizio & TCL for a reason ,ther are no free rides and my electronics education and fortune co management knowledge of supply and mass production at global multinationals backs that up but OTOH all these companies bear watching and TCL may be a legitimate value lead product .

IMO Hisense USA product ( so far) & Vizio have not shown tier one level design , quality controls and parts content.

TCL may have more muscle than both of them anyway and Vizio is 5x smaller puny OD design/ seller only they don't even make TV's but Hisense bears watching and they are large scale .

The new Premium KS, MU and Q.X 4K HDR TV Samsung smart hubs and smart TV platforms are faster and miles ahead of anything else in a TV right now so is the Samsung CPU (SoC) . They may be in the 4K SDR KU6300 XX6X00 also or maybe something a little different .

I have the latest Sony TV Andoid smart TV platform in my 2015 4K HDR Sony TV I shunted to the family cinema room and it's a slow ,unintuitive unstable kluge on a rubbish and intolerably slow Mediatek CPU (SoC) like the new Sonys .

But... everything is so SMALL, can you see anything? The letters? I am using a 32inch tv (1080p!) and need to zoom say to +200% on chrome, and I am using the Magnifier (+200% too) to see the letters and stuff and no I don't have eye problems! I am like 2 meters away from the tv that's why probably (if I get even to 1meter my eyes hurt), so on a 40 inch how far do you sit from the tv? Don't your eyes hurt if you are close ?

Look at the pictures, he's using it on his desk as a monitor, so he would be sitting way closer than 2 meters. Probably more like 50 cm. I guess most people can sit in front of a computer screen at that range without their eyes hurting (whether it's really good for us is another matter ;))
 
Tis not hard to scale a windows 10 PC screen signal to larger font and so on, mine is at 125% on the 27" monitor in front of me and 125-150 % on the Samsung KS 8000 4K HDR 1000 55" TV on the full motion mount in here .

Again that said for lt. office and web general use I prefer this 27" PC panel on the articulating gas charged monitor arm anyway .

The swift new Samsung smart TV platform in the TV can get anyhing usual on the web including w/ plausible embedded Chrome & Youtube remote web browser launchers and IPTV up to 4K HDR & same at Youtube and up to 4K HDR protected movie /TV content without the PC anyway .

I pass the nude optical 5.1 up to 96/24 audio data out to a spendy Sony ES 7.1 AVR in a spendy 5.1 for external decoding from the PC or TV or @ HDMI media platers or PC and D*TV DVR client in here if I want and likewise in the 4K HDR family cinema 5.1but no PC in there only TV optical out and HDMI external souces in

The TV and digital audio workstation /gaming PC + 40" Sony Bravia 1080p LED TV optical audio or PC midi data /usb audio goes ultimately to large spendy Amps & JBL pro speakers all THX PM3 Pro certified sound wise on 20 amp dedicated circuits in the PC/Game /drive sim /music room but like 2 more bedrooms no PC in the family cinema just smart TV, media players and NAS media HDD access .

pppffttt the new 55" Samsung TV in here has a subwoofer in it and plausible 40w each speakers and it's not 2" thick (only 1.7" ) ,Imagine that, now I can actually power down the spendy Sony ES 7.1 AVR on a lot of TV viewing in here .


I can get clean THX pro 115dB -20 dB (or more) @ 5.1 and 10 -15 feet in my man cave here with the 5.1 for rousing genuine theater level movies or TV on the audiophile grade ELAC speakers + my (other brand ) sub and my custom 6 driver 2 way center or clean audiophile 2.0/2.1 music at elevated levels but no newer HD audio surround formats ,but I can see that for some folks given legacy DDXX and PLXX digital 5.1 are only .acc lossey like high bit rate mp3 .

I've been using my 46 inch Samsung 1080 set for years now as a monitor and have had zero issues. Once I was able to get the settings just right for text, resolution,etc., it has been fine. Games and Windows are all great at 1080. Only now am I going to upgrade to a 4k set. Looking at 65 inch since I am about 10 feet from the screen in my living room.

It's doing it while he's at his computer I believe.
 
55" Samsung KS8000 user here with 175% desk top scaling. Diablo 3, BF1, youtube, surfing and Foxtel (pay TV) never looked so good. I could never go back to 27 - 32".
 
That crap doesn't mean the input lag is low.
Below is MY 2016 4K Samsung HDR 1000 10 bit QDOT 2B color TV @ 1474 NIT (cd/m2) luma power and same to 6000 NIT tone mapping luma power and 7000: 1 Contrast

I'm Not a PC Game boy or PC drive sim boy beyond 1080P ultra on a 40" 1080p Sony Bravia TV in another room for that at a casual level ofc., on a purpose built core i7/ X1 (2K EVGA gaming maybe 3- 4GB ) nvidia d/GPU PC in there all on air ,nothing exotic, state of art ,underwater or w/ a coolant radiator .

OTOH just curious How does all this look for TV panel PC gamers which implies casual PC gaming AFAIK.

My 2016 Damung 4K HDR 1000 55 KS 8000 TV puts on a moving samsung white logo on ultra black panel at a reasonable amount of time in TV ,PC or game modes and AFAIK the TV remote center orbit button wakes it up and my 55" 2015 4K HDR Sony instead turned off the picture like that.


I think they may have face /presence detection I know the Sony does and you can lay down and watch either one all night without that screen saver or fall asleep TV stays on and if I don't look at Samsung TV in here next to the PC /exec office desk on a motion mount while on this PC long enough ,the screensaver comes on in the TV no matter what the TV is doing .

These new smart TV platforms are just ARM PC and panels up to 4K HDR now with a digital RF tuning ASIC and this thing can do the web surf (chrome) plausibly and up to 4K HDR Youtube and IPTV like Netflix and play direct from USB media drives or Wi Fi LAN or wired LAN server ,media player or STB or cell phone /tard pad or mirror the mobiles or play cast videos ,

I use it for what it does better than this 2016 core i5 W-10 PC (lots) now and for TV & media and very occasionally a 2160p Ext. desktop instead of or with this 27" screen

If you are doing color sensitive work like photography or video editing TV's dont support digital color spaces like sRGB/AdobeRGB.

No, Nothing like that, I'm a coder... So basically if I get nice clear text I'm happy enough :) Something a TV used to fail quite badly at in my own experience.
 
But... everything is so SMALL, can you see anything? The letters? I am using a 32inch tv (1080p!) and need to zoom say to +200% on chrome, and I am using the Magnifier (+200% too) to see the letters and stuff and no I don't have eye problems! I am like 2 meters away from the tv that's why probably

Seriously? I'm 2.5 meters away and see perfectly fine. When web browsing, I have Chrome set at 110% zoom and everything is a nice, easily readable size. Yes, text is small outside of the web browser but it's still readable. At least to me anyway.

IMO 1080p is a waste of time on a 32" + TV panel outside gaming , Youtube or casual e mail ,or Google casual surfing . PC panels are not TV panel and pixel structures often differ or they should .

This 27" 1080p PC monitor has virtually the same pixel density as my two 55" 4K HDR TVs at 2160p >1:1 Pixel on windows 10 from this PC

You must size Windows in settings >display appropriately @ 125 % or more @ 4K 40" + panel at the right view distance for the applications 4K 40" can be 2+ ft 4K .55" ~3 + ft .

2160p 4K windows 10 looks great on my 4K HDR 55" TV @ ~3 " or closer if you want to move your head to much
☺☺

that's all you have to do outside of Chroma if using 4:4:4 software or games/PC or sRGB on a PC at maybe 4:4:4 if the TV doesn't support it and 4K on a PC is peachy keen in windows 10 if your PC can make that 2160p and you mind your screen distance and windows scaling for the application .

.The web is fine at 4:2:0 below HDR but 4K HDR smart TV figures all that out if its a newer good like this 2016 4K HDR 55"Samsung QDOT beast and you manage the HDR TV HDMI ports ,most PC can't do 4K HDR anyway outside of a spendy d/GPU or Intel Skylake CPU ,

All TV /Movie content ,broadcast and TV media protected content below 4K HDR is 4:2:0

4K PC Windows 10 and its as good as you make it and note YcBcr 4:4:4: or 4:2:0 Chroma (*depending on what you are using in the PC that requires 4:4:4: ) is the bogeyman for clear text on a TV panel from a PC if you don't set it in the PC (PC defaults ) and or if your TV does not support @4:4:4

Again All SD ,HD ,4K SDR content & media below 4K HDR is 4:2:0 and additive sharpness must be zero below HDR or 0 on a Samung and 50 on Sony TV and 1:1 pixel or fit to screen on some.and 4:2:0 but 4:4:4: is often fine on 4:2:0 TV/PC content but incorrect .but not so much the other way around .

We should calibrate TV and PC panels to conforming standards and your room light variables or at least a black pluge test and conforming white clipping test and color saturation below clipping same in conforming standards ,My TV (5) and PC & panels (4) are all electronically calibrated by me and preferences beyond that but verified not to clip or crush details or conforming color gradations or if beyond all that as usual on my HDR TV's in panel range

..I use a 65K white BIAS light kit behind the TV and PC Panel in here at dusk,dawn and dark like the pros it enhances contrast and reduces eye strain and must be 65K white not colors once you use one you won't be without it trus`me .

Antec 65K white TV & PC panel BIAS lights (LED strips) are cheap even at Amazon

55" 4K TV is way better at all this than a 1080p if situated and set well

The Caveat is ,40" 4K panel will have a much higher pixel density than 4K 55" given 55" 4K *is virtually 27" @ 1080p ,

If you set it up 4K PC close in is fine if you mind your normal or adequate PC *reading vision peripherals and don't have to move your eyes orb head so much on a large panel to close in on Windows or whatever at 55" or less . 40"-49" is good spot for 4K desktop PC TV panels

OTOH @ 2K- 4K 65" PC you need to sit back in room at the correct vision peripherals period and I don't think its all that beyond causal google or youtube ,whiteboard .Powerpoint ,Excel ,slides or content consumption and conferencing


ppffttt it's not like they don't have 27" and XX" 5K PC screens nobody is complaining about in 2017 ha ha ☻☻☻

I've used TVs as PC Monitors for years, and here are my thoughts:

1: Older TVs sometimes have issues with PC content over HDMI. On my old Samsung UNC7000 series. I had to specify the HDMI Input I was using from my PC as "DVI PC" and had to go through a DVI to HDMI conversion out of my graphics card. This isn't an issue on newer TVs; my new LG B6 didn't have any of these issues, though I still specify the HDMI input as "PC" to avoid problems.

2: In regards to "best" settings, the optimal is always Full Range RGB. Full Range RGB is essentially equivalent to 4:4:4 without an extra format conversion; it really isn't necessary on a PC. Aside from that, remember that at 4k 60Hz HDMI 2.1 spec doesn't have the bandwidth to handle Full Range RGB/4:4:4 at more then 8bpc, though this isn't a huge issue, since most games are probably going to go the full HDR route anyways (10/12bpc is still SDR in this context).

3: Latency is a problem on certain displays. "Game Mode" is always a must. On my old Samsung UNC7000, "Game Mode" latency is measured at ~28msec (just under two frames). Same on my new LG B6 (though thats with HDR content; SDR is a closer to 16ms). And I note: most monitors are worse. Check before you purchase (rtings.com does a good job, as does avsforum). In any case, even good PC monitors aren't suitable for a competitive environment, though should be fine for everyone else.

4: On larger TVs, you'll almost certainly want to increase DPI. I'm using 175% DPI on my LG B6 (55"). Works well enough, though some programs don't play nice with DPI settings, and even Windows DPI support is a bit hit or miss. Alternatively, keep the desktop at 1080p; whichever works best for you I guess.
 
Great article!

Just wanted to say I am LOVING the 32" 4k monitor that Shawn shipped to me 10 months ago! Not sure I'd personally want to go bigger. I do keep on of my 27" 1080 screens in use though, but I'd like to replace that with another 4k screen I the future.
 
"...it’s worth noting that the UN40KU6300 offers true 4K UHD resolution of 3,840 x 2,160 pixels..."

Not quite accurate there. The term "true 4k" specifically refers to the professional and cinematic resolution of 4,096 x 2,160. The "UHD" moniker (which is NOT "true 4k") is a consumer grade resolution, the aforementioned 3840 x 2160. The big box stores and online retailers still stamp the "4k" on everything that is UHD, but this is largely considered false by the A/V community at large and is really nothing more than an advertising gimmick used to sell TV's to those who don't know any better.

Look it up...

"...it’s worth noting that the UN40KU6300 offers true 4K UHD resolution of 3,840 x 2,160 pixels.


So does nearly every 4K TV on the planet now like my 4K HDR 1000 Samsung QDOT UN 55 KS 8000 in her on the wall and my 4K HDR Sony Triluminos X850C here out in my family cinema room

OTOH only my Samung UN KS 8000 is real deal HDR 1000 certified and 1000 + NIT luma power here ,the Sony is more of a wide color 4K SDR TV

My Samsung = can do 1474 NIT and tone map to 6000 NIT ,AFAIK HDR TV content can't even do that yet but tone map only to 4000 NIT with the usual 100 NIT mean and averages like 4K SDR and 2K HD mean and averages but up to 1000 NIT or a little more on HDR transient peaks and highlights in the HDR content but below tone mapping .

My Sony = 420 NIT HDR and SDR peak no match for the 1474 NIT Samsung UN KS 8000 here kinda like your UN KU 63000 ,same thing no real HDR but a nice 4K SDR TV .

Not quite accurate there. The term "true 4k" specifically refers to the professional and cinematic resolution of 4,096 x 2,160.

https://www.extremetech.com/extreme/174221-no-tv-makers-4k-and-uhd-are-not-the-same-thing

You are and your web source are for lack of a better word incomplete here and 4K cinematic resolution won't be any better on a 4K UHD TV panel unless it's a large cinema theater screen size .The difference is trivial as it applies here and the important thing is what see we from where we sit and that small difference is nothing as it applies here but you web blogger source sounds like only ignorant parroting of what he read anyway .

There are a number of 4K resolutions but for UHD TV panels outside of the few odd IIRC Sharp Display 4096 × 2160 TV panels some years back , TV manufacturing companies ,TV and TV media content producers ,ITU standards committees ,FCC (ATSC 3.0) and regional standards committees have hava all ratified (4K) -Ultra-high definition television @ 3840 × 2160 1.78:1 (16:9) 8,294,400 pixels as the prevailing standard and up to HLG HDR for ATSC 3.0 linear broadcasting. IPTV can be HDR-10 , (HDR10 + active HDR maybe soon) and or DV HDR and maybe active DV HDR soon .

4K UHD TV 2160P (16:9) 3840 pixels × 2160 lines was a nod to compatibility with 2K 1080p (16:9) screens and so on and a fair compromise all around

HLG HDR is for linear broadcasting I believe my new Samsung 4K HDR TV has that already or will see it in a firmware push but no ATSC 3.0 RF tuners ha ha .

This has nothing whatever to do with box box stores or marketing they just sell and market product the manufacturers put on the shelves unless it's a OD or re label product from a store chain like the Best Buy exclusive Insignia /Dynex TV OD product lines but all that would have to be in conforming standards for a TV anyway ☺

The important thing is the TV /media content and TV panel TV being at the same resolution without re scaling here as you would with anything below 2160p UHD on a 4K TV ,

LOL Cinema production 4K 4,096 x 2,160 or other cinema 4K resolution digital intermediates for TV content are scaled down to 4K TV 3840x2160 and as as often as not up from 2K digital intermediates for 4K TV 3840x2160p Content and 4K Blue ray and they have way better scalers than our TV's or media players

Caveat emptor when you buy or even watch streaming IPTV 4K protected studio movie content or 4K Blu ray ,the provenance , cameras used and % of 4K production shooting and 4K D.I. (digital intermediate content ) used on any given film they have there is is at Blue ray .com .
You will see a lot of that is entirely or partially from upscaled 2K D.I. and HDR is apart from resolution at that point but implied in 4K HDR HDR TV and I gave seen Amazon video 4K HDR drop down to 1080p HDR here more than once due to net congestion from AWS through the CDN hops ..........LOL

Like 3D and 2D % in a 3D film shoot ,You would be surprised at how much 2K intermediate content and GCI is in a 4K cinema production or UHD Blu Ray even at the movie theaters from thier cinema digital packages because of that today trus`me

"To many monitors" ??

Don't you mean "Too many monitors" ?

Anyone who can't spell "too" has no business publishing anything. They have one concern: getting some remedial English lessons.
A bit over the top. The person could have been typing quickly on a phone. The person may have not treated this like an English essay and double checked everything three times. As long as it's understandable to the average person then it's fine. Everyone makes typos. No big deal.

No, it isn't. This isn't OCD grammar stuff. It's very "common-sensical," and not even colloquialism. With the advent of spell and grammar checkers, this should be a no-brainer (yes, even on a smartphone). This is expected, respectable practice for professional publications, semi-professional articles, blogs, most emails, and yes, high school essays, and *gasp* even elementary school grammar lessons. -10 for spelling.
