Using HD-TV for better PC resolution? |
|
|
I've got a HD-TV connected to a PC. The picture is big, but not
particularly hi-res. If I get a HD-video board for the PC, will the
screen resolution look any better? If I play a MPG or AVI using the
HD-board, will the output on the TV look better than if I used the
regular video/tv board?

If you are trying to use it as a computer monitor you need to use either the
DVI, HDMI, or Component inputs on the TV. You may have to do some tweaking
with Powerstrip before you get the timings right if your TV isn't designed
for that kind of use and your video board isn't set up to support HDTV.
An HD video board is for receiving high definition television transmissions,
not for displaying them--that's a function of your video board.

If your TV is a direct-view plasma or LCD, the results may be good, but
really only if you set your computer to output the native resolution of the
panel (which in many cases, for plasma particularly, is NOT 1280x720 or
anything you'd expect). DLP might be ok too, and maybe LCDoS, I'm not sure.
If you have a CRT, either direct view or rear projection, you will most
likely be disappointed at the results. The equivalent resolution may come
out a lot lower than you expect, partly due to the interlace. Maybe the best
results might be to output 1920x1080, but using the largest fonts your
system can be set to. But there may be problems with horizontal lines
(flickering and the like); fine detail just isn't going to show up. Or maybe
set it to a much lower resolution (like maybe 854x480 or something,
approximately EDTV resolution). I'm not sure, but either way, it is NOT
going to resemble a 1920x1080 computer monitor! |

First of all is your TV real HD? There are 2 HD resolutions 1280x720p and
1920x1080i and if your TV doesn't support at least 1280x720 pixel for pixel it
is only ED TV. some TV's claim to be HD but they can't display HD signal
without downscaling and that won't work too well on PC signal. Second of all
there is whole bunch of settings beside resolution and refresh rate but you
need powerstrip.exe to be able to set them up. My LCD panel will display any
resolution my video card will output. However even at it's native resolution of
1280x720 PQ sucked untill I found the right front porch, back porch and sync
width settings. It took some time to find it but once I got it, there was no
mistake, the picture was perfect. Most new, good quality video cards from ATI
and Nvidia can go up to 1920x1080 resolution without much problem, very few HD
TV's can actually go that high without downscaling so you should stick to
native resolution of your TV, whatever it is. If the computer and video card
is fast enough to decode HD MPEG2/4 on the fly without pixelation, skips etc.
on the computer monitor, it should look as well on TV. Besides timing settings
you may need to tweak color, tint, gamma on the video card to match it to your
display as well. |
