32" LCD TV as monitor (DVI) [SOLVED]

[RACKnRAIL]

I just bought a new 42" plasma TV for my bedroom, so I want to use my old Costco special 32" LCD TV (Daytek 720p) as my new computer monitor. The computer I want to use with it is a 2.1 ghz amd sempron, 1 GB ram, with a 128 mb nvidia GeForce FX 5200 and Windows 7.

It works with XP on the same computer, but the problem is I can't seem to find a windows 7 driver that works with the TV. I'm currently using a Vista driver which works fine with a regular VGA monitor. It even works on the same monitor using a VGA to DVI adapter. However, when I try to run it from my TV it says no signal. I have tried setting various different screen resolutions on the VGA monitor and then hook it up to the TV to test, but no cigar.

Any ideas? I really don't want to go back to XP, but it appears my only option. I would really appreciate a working solution.

Does it have HDMI? I'm running a DVI-HDMI adapter and it behaves fine. The DVI is on my video card, and the HDMI is on the TV. If you can do that, things will probably be fine since they are both digital. I bet the problems you are having is from the analogue conversion of DVI and VGA.

The card is not hdmi. It's only a 128 mb and it only has VGA or DVI.

The card worked with XP on the same computer, so it's not analog conversion.

update:

I have tried true color at 16 and 32 bit, and high and low refresh rates, still nothing at the recommended screen resolutions. In fact my graphics card will only go to the lowest recommeded screen resolution for my TV 1280 x 768.

After installing Windows 7 on 3 of my house computers, this is the only one causing me problems. The computer and TV in question worked fine with XP. I know, because I tested it before putting Windows 7 on it. I guess I should have done a bit more homework about that graphics card and win7.

I was forced to use a Vista driver for it, so I am thinking it must have something to do with the older 128 MB graphics card and driver.

I asked if the TV had HDMI. Only the newest video cards have HDMI.

My old 32" TV didn't like to behave well while being used as a monitor because I used the VGA port. It wasn't until I got my new 47" that I was able to try out the HDMI port on it(lack of cables) and I found then that the HDMI port was broken. Anyway, my point is that if the TV was meant as a TV and not as a monitor, you are going to have some troubles. That's what I love about my current TV and it's digital connection: it actually acts like a monitor.

This is my old bedroom TV. I have a 52” BRAVIA in my living room, which is naturally HDMI. My problem was with my old 32" Daytek LCD, which does not have HDMI. The TV is limited to using DVI or VGA.

I solved the problem. I went to the computer store and bought a used geforce 7300 GT 512 MB card for $35. It now works with Windows 7.

I'm sort of glad, because I can use that card for a motherboard/chip I have. I have everything I need to build it, except for a small tower to fit the small motherboard.
