Connecting VGA to HDMI bad idea?

You would need more than a $40 cable to take a VGA output from a computer and feed it into an HDMI input of a monitor. VGA uses analog video only and HDMI is uses digitally encoded video. You would need some type of video converter box

If the TV has a VGA input then a VGA to VGA cable would work for you. If the computer is a desktop model, you might want to consider putting in a graphics card with an HDMI output.

 

DVI and the video portion of HDMI use the same digital signals. You would need a DVI to HDMI cable or an HDMI cable with a suitable HDMI to DVI adapter added on one end.

The HDMI standard supports digital audio while DVI does not. You would need to see if and how the TV can handle inputting audio while using the HDMI connection only for video.

 

You're welcome.

Please let us know how this turns out.

 

Please take a look at the attached DVI connector configuration chart. It is for the male plugs found on a DVI cable.Tell us which connectors on the chart match the female DVI connectors on the TV and card.

The DVI standard supports both analog and digital video signals. Too long of a cable length could make for fuzzy analog signals but would cause a total loss or drop outs of video for digital signals. if the video resolution is low enough and the cable quality is high enough you might be able to run a 50 foot cable without problems.

Please let us know the native resolution of the TV. This would be the number of horizontal and vertical pixels that the TV can display without any kind of internal resolution conversion. Then find out if your video card supports that resolution. Matching the card to the TV is not a matter of the physical size of the display but on the number of horizontal and vertical pixels and the refresh rate.

Yes, when using DVI, you will need separate cables for the audio.

 

The 1080i number is the vertical resolution and the matching horizontal resolution would be 1920 pixels.

The 1680 x 1050 resolution of the 22 inch monitor is LOWER than the 1920 x 1080i resolution of your big screen.

You would need to find out if your graphics card supports 1920 x 1080i operation. I believe that your "GF 6600" reference is for the graphics controller IC on the card itself, not the brand or model number of the card itself.

A Dual Link DVI-D cable would be used to connect the card to the TV. Somebody else here familiar with real world usage of DVI cables would need to tell you if your 30 to 35 foot cable run can be done.
