  1. Exactly what resolution on a lcd computer screen is equivalent to 1080p on a tv screen?

    The is no exact equivalent because the aspect ratios of computer screens and entertainment are different.
    1080 in TV means horizontal lines. A 1920x1200 computer screen fits the bill (it is exactly the correct width) and 2560x1600 is more than enough.

    The attached Excel sheet by Carlton Bale may be helpful.
    Resolution relates to screen size... so it is difficult to compare.

    Yes, I would... but not the highest... it is generally the highest for a laptop, but for desktops, one of the highest easily available is 2048 x 1536, and the highest LCD monitor for desktop computers that I have used is 1600 X 1200.

    I don't know how all this relates to HDTV, since I don't have one.

    Your best information will probably come from a video graphics website such as nVidia or ATI, or from a good lcd monitor site such as Sharp, LG, or Samsung.

    1280x1024 does 720p HD.

    The HD you hear of 1080 and 720 are the vertical heights, so the 2nd number in screen resolution.

    You will need something with 1080high to do the 1080i or 1080p stuff you hear about when discussing HD. As Nodsu says you also need 1920 pixels wide. So you are looking at 1920x1200 to do it. 1680x1050 will get you close on height, but you are short quite a bit on width.

    16:9 and 16:10 are just the ratio of width to height.

    ok i think i understand now. So basically the bigger number of vertical pixels, the greater resolution. One thing i dont understand is why a 1280 x 1024 would run in 720p but not 1024p. Isnt the second number higher meaning a higher resolution?

    HD content doesn't come in 1024p, it comes in 720p, 1080i, and 1080p. Now depending on the aspect ratio its filmed at it may not have those amount of vertical lines, but the horizontal associated with them is fixed.

    I think the horizontal for 720p is 1280. Which is why a 1280x1024 monitor can do 720 content.
