42" LCD TV Vizio with PC conectivity, help.

[Yamaheart]

Hi all, I tried to use the DVI cable with the HDMI connector for my LCD, the color is fading, where blue becomes green. But when i use the regular RGB (PC input) it was fine. I thought DVI from PC to TV thru an HDMI adapter should make better quality, but not. Is there something that i did wrong? Please help. Thank you.

The main reason to go digital (DVI on the computer to HDMI in the TV) is to avoid using the VGA port in the TV, as that port most likely falls way short of the native resolution of the screen. Example: If your screen resolution is 1920X1080 (16:9 aspect ratio and 2MP) and the VGA port only supports 1024X768 (4:3 aspect ratio and .8MP) the picture you get from the computer will be distorted and blurry. Going from DVI to HDMI is a much better choice because your HDMI port should at least support the native resolution of your screen giving you the potential of having a perfect image if you send it the ideal signal.

I don't know why exactly you're getting fading and messed up colors. It could be the cable, your HDMI input or something worse. My suggestion is to start small by using process or elimination. My guess is a new cable woud fix the problem. Maybe buy a different brand with a good return policy in case it doesn't work.

Btw- I assumed you are using a conversion cable with a DVI connection one end and an HDMI on the other. If you're using any additional converter parts I would be suspicious of those too.

Thanks,

Well, what I did was simple. I bought the DVI to HDMI adapter, I used the regular DVI cable. One end is hooking up to the computer, and the other end is hook up thru the adapter and to the HDMI port to my TV. That worked but fading color like i said. Should i use the Dual link DVI cable? Or that just the DVI to HDMI adapter that is cheap? Rekced, have u tried this before and does it work? thanks

I have never attempted to split computer signals before. I have always just purchased a video card with the outputs that I needed (they can be found for under $20. That's less than an adapter!) and ran a separate cable to each display. The cable going to the screen should be DVI to HDMI. They also make video card with DVI and HDMI. That would really be ideal.

Perhaps what you have will work, but you got a defective adapter.

Dual Link is specific for high res monitors. 1920x1080 isn't one, so you shouldn't need that. Also, sometimes Dual Link cables exhibit problems on non-Dual Link compatible video cards.

Does the TV have multiple HDMI ports? If so, have you tried them all just to eliminate the port itself as a point of failure?

Also keep in mind the possibility that the video card is at fault. Unlikely, since you said your VGA out works, but possible for the port's connections to be bad/damaged/blocked.

I agree with rekced, it might be fiscally advantageous to just get a new vid card with HDMI output. Depending on the card you are running now, it might be a very cheap upgrade.
