That I had to be very careful about refresh rate. Your average PC user is not going to put up with this area any longer. That is, the days of tinkering appear to be over. So with that out of the way I find my self using the control panels to set the scan rates to get it to work. Sadly as the industry never standardized this, I can't be more specific.
I recently bought a 42" Panasonic LCD TV (TCL42U5) with VGA input. I assumed that I would be able to use the VGA input with a 1920*1080 resolution setting on my laptop and that it would display nicely on the new TV (fill the entire screen without any black bars.) The manual for the Panasonic is a piece of garbage and doesn't include the list of compatible input resolutions. As far as I can tell from experimenting, it doesn't support any 16:9 options!!
So I did some more research and found a model from Sharp that was about the same price and the online manual explicitly stated that it would support 1920*1080 when using the VGA input (LC42SV50U.) I went to the store with a laptop and when I switched it to 1920*1080 the TV said "NOT SUPPORT" It did take 1280*720 (an improvement over the Panasonic,) but it compressed the image with bars on the top and bottom and the salesperson said that they could not be removed.
Am I doing something wrong? Perhaps a problem with the laptop? It seemed like a given to me that an HDTV (which has a native resolution of 1920*1080) would properly support that resolution from the VGA port. Are there any models in that price range that will give me what I need?
Thanks for any advice!
