Connecting a HDTV to a computer

[fazers_on_stun]

I started a new thread but no response (http://www.tomshardware.co.uk/forum/291984-15-monitor-flickers-connected-hdtv-hdmi)
Basically, my problem is when i connect my PC to the HDTV, the PC monitor starts flickering. Any ideas?

PC config
q6600
4GB ram
2x 250GTS SLI
Philips 22" 220VW (1680x1050)
HDMI cable over DVI to HDMI dongle

Sorry for tacking onto another thread but i am desperate

So what type of PC monitor are you using - LCD or CRT? How is it connected to your video card output - RGB or another DVI connection, on the same vid card or the other? What OS? Are you using the latest version of nVidia's display control panel to set up your display? Anyway, it sounds like your display is not detecting you're using both the HDTV and PC monitor simultaneously. I'd try using the "set up using multiple displays" wizard in the control panel first, assuming both the monitor and TV are detected properly and the resolution and refresh rates correctly set for both.

It should be simpler then it is, but it isn't, you are right. First time I tried to connect to a regular TV (none HDTV) I couldn't see anything, because the monitor refresh rate is much higher then the refresh rate of a TV. After fiddling around with it for a good part of a day, was finally able to sort of see the very poor video. Text was impossible to read and just a real disaster.

Two weeks ago, I again tried to connect my computer to an HDTV. Figureing that with the hardware updates and the better TV we would surely be able to make it work. I use SLI computer and connected the HDTV out connector from the card to RGB in on HDTV. This should have worked, but no...the screen was all bleached out green mess.

I noticed that when I started the computer (rebooted many times trying to get it to work) that the VGA part of windows (no nvidia drivers loaded) would give me the nice colorful look as seen on a desktop. However, once the drivers were loaded from Nvidia, the screen was crap. If I remove the drivers, the screen looks as it should except for very grainy and pixelated. Loading the drivers again makes the screen bleached out green. So the drivers are **** and the vga default driver from windows makes the screen as ugly as it was years ago.

I say this in hopes someone will tell me where I went wrong, and possibley get a discussion on the correct way to make $600, to $1200 cards work with a $3000 to $10,000 HDTV. Why the heck can't we make this work folks?!

Help us please!

it sounds like maybe you need to search the video card's settings and switch the output from component Y/Pb/Pr to R/G/B. Did you try that?

There are methods to connect a PC to a HDTV. These include S Video, component video, and a DVI HDMI converter.It should be acclaimed that DVI cannot backpack audio amid two sources so you will need to find another way to get your audio output if using one.

your GPU should support higher refresh rate
