Help w/ hooking PC up to E44W46LCD TV

[vlad]

Hi,
I'd like to start a thread for all of us using the DVI input to hook a PC up to our E44W46LCD.

I just got this TV and hooked this up this week from an ATI Radeon 9200 across a 3m DVI cable.

After playing with it for a while (no idea what I was doing) I got a perfect full screen on my TV by settting the resolution to 1024x768. My PC is also set to the same. I could only get it to work as one continuous desktop (i.e. I had just wanted two versions of the same ONE desktop as opposed to an extended desktop).

Having said all that, I don't know if any of what I did with the resolution setttings are correct. Is there a way to acheive just one full desktop replicated on my TV but with the 16x9 resolution.

My main problem though is whenever I hook my DVI cable from my PC to my TV I get some kind of low humming noise whenever my TV is set to the Component 1 (which is my hdtv box) and I get two faint horizontal lines scrolling up the screen. Its some kind of interference, but I dont know if that means my video card is messed up, or if something isn't grounded properly, I'm new to all this, so any help with this and the general setup would be really appreciated. Thanks

I had similar problems hooking up ATI cards to both TV's in my house. Happened when I had the TV and dometic cable hooked to the TV at the same time - some kind of ground loop I think. Solved problem by running a wire from the ground on the wall socket to the outer part of the cable (cable TV ground)

thanks, I suspect it may be eletrical interference, When you say you ran the ground to "the outer part of the cable" can you be more specific?
thanks.

You need to connect the ground that the TV uses to the ground that the computer uses. Best way I found was to run a wire from the cable outlet ( wrap a wire around the silver threaded portion that sticks out of the plastic wall plate) to the ground on the wall socket that the computer is plugged into. There are also power bars that have filtering in them that may help - I think Monster makes one that I saw someone say had helped them.

You can get 1280 x 720 resolution with your ati card,
on the zenith instead of setting to DTV-PC use DTV-DVI.
There is a bit of overscan put you get the right aspect ration.

I'm running an HTPC over DVI to this TV, and I have 6.5% overscan or so (which I can fix with the nvidia drivers). Unfortunately this overscan is not caused by my video card. I also get overscan when connecting a regular set-top HD reciever as well. Any help would be appreciated.
