There are apparently lots of HDTVs out there without VGA jacks. Â I know this because we’ve sold a lot of VGA to HDMI converters. Â Our first offering in this department worked well, however we had a fair amount of returns because the resolution available from the PC had to match what the HDTV would accept. Â And some HDTVs are pretty picky about what they will accept.
Our 2nd generation VGA to HDMI converter, now available at PCTVCables.com, now includes a “scaler function.” Â This unit will take most common PC output resolutions and automatically scale the image to a fixed 720p output. Â This should be compatible with almost all HDTVs. Â The new unit costs a little more but is guaranteed to work.
When I first received and tested a sample, I found that the image was shifted on my HDTV. Â This was easily corrected by turning off my PC’s VGA output (using the Monitor Key Method), and then turning it back on again. Â It turns out that the converter must be connected and turned on FIRST, prior to enabling the PC’s VGA output. Â This is because the converter will automatically communicate with the PC when you enable your VGA output via DDC and detect the resolution. Â The converter will then scale the image correctly.
As always, we sell all of our video converters as complete kits. Â So when you receive your product you will have everything you need to connect your PC to your TV.
