1080p not showing in HD

  1. I have a 22" Samsung Syncmaster T220HD display connected to a Dell Optiplex GX280 SFF PC via HDMI. Recently, I purchased a Sapphire ATI Radeon HD4550 DDR3 512MB PCI-Express low profile video card. When I set the resolution to 1920 x 1080i or 1280 x 720p the picture is in HD; however, when set to 1920 x 1080p the picture doesn't show in HD. Why is this? Shouldn't 1080p be in HD??

    perhaps "HDCP" is not supported on the video card?

    What do you mean it's not in "HD" ? If your monitor supports HDCP & has a resolution of 1920 x 1200, you'll see black borders on the top & bottom of the screen.

    If it doesn't support HDCP, it'll either be in a lower resolution or will display an error message. Which do you get ?

    For example, if I play videos on YouTube that are in HD (720p or 1080p) it doesn't look HD, or if I play movies that I've downloaded that are 720p or 1080p they don't look HD, but only when the resolution is set to 1080p... when I set it to 1080i or 720p they look HD.

    My monitor is 22" so I think the original resolution is 1680 x 1050 but since I bought the graphics card and downloaded the driver I'm able to switch the resolution to 1920 x 1080.

    When the resolution was set to 1080i, at first, I got black borders on the top and bottom. I managed to adjust the resolution with Catalyst Control Center to remove the black borders, the resolution was lowered from 1920 x 1080i to 1728 x 1028i; however, the picture still looks HD, I can tell the difference in how the picture looks when playing 720p & 1080p movies.

    When the resolution was set to 1080p, at first, the screen had black borders about 2 inches thick on the top, bottom, and on the sides of the screen, I had to upscale the screen size with Catalyst Control Center in order to remove the black borders. So, I managed to get the screen size to fit my monitor without having any black borders, but it still doesn't look HD. 720p & 1080p movies look exactly the same as they did when the resolution was 1680 x 1050.

    I'm not sure what HDCP is but I'll look into it. How can I find out if my monitor supports HDCP?

    hmm i got a 2007 19" LG LCD (1440x900) it has HDCP and so when i view a 1080P the video will be resized to the LCD native resolution. when i check the resolution using some software it says input video is running at 1920x1080.

    im not so sure about these HDCP thing but i'm using nvidia and in control panel it says "your graphic card and your LCD is HDCP compliant" something like that.

    anyway your LCD looks newer than mine and definitely supports HDCP, according to this:

    how about just leave your resolution to its original and try some 1080p videos from outside YouTube? some free videos here : http://www.demo-world.eu/trailers/high-definition-trailers.php
