Issues Connecting Vizio TV to PC

Hello,

Thanks in advance for any help that may be provided by kind visitors of this thread. My issue is thus:

I am having issues hooking up my parent's Vizio L32 HDTV10A to their PC as a secondary monitor. The PC has an AMD chipset (I can find the exact model if you think that will be relevant) with 2 DVI-D Single link ports. One port is directly connected to the PC monitor, while the other runs through a DVI to VGA converter, and ultimately into the RGB port on the Vizio monitor. The Vizio TV is being detected fine according to Windows and the graphics card software.

The issue I am having is that no matter what resolution or refresh rate I set the TV display to on the PC, the signal doesn't seem to be accepted. The TV will flash the image of their PC desktop for 1-2 seconds then turn blue and display a "Signal Not Supported" message, repeating this process over and over.

Looking through the online manual for the Vizio television, I found the native resolution to be 1336x768 at 60 FPS refresh rate. Display compatibility is listed as 720p and 1080i. Signal compatibility is listed as 480i, 480p, 720p, and 1080i. I'm a little uncertain on exactly what Signal and Display compatibility are here in relation to graphics cards and how to change/manipulate them. Using the preinstalled AMD graphics software on the PC I was able to alter the signal (I think?) to 720p with 1336x768 resolution but the problem remained the same.

Just for the sake of troubleshooting, I hooked up my Toshiba LCD TV (which is much smaller and apparently a little newer). It worked just fine--without any adjustments my parent's desktop was displaying on my monitor.

So, I'm not exactly sure what the issue is here. Perhaps there is some incompatibility between the Vizio TV and the AMD chipset on my parents PC? Or perhaps I am just not setting things up correctly? Please let me know if there is any more information I can provide, or if anyone has any clue as to what my issue is and how to fix it.

Thanks Again,

I have not, but the specific path was chosen because the HDMI port on the TV is being used for another device. Did you discover a solution to your problem or what specifically caused it in the conversion process?
