We got a large TV from somebody for free because the external tuner/DVD/VHS box died. After no luck trying to fix it, we threw it away. It attached to the box with a standard DVI cable, so the screen currently acts as a giant 1920x1080 monitor, and nothing more.
I'm able to plug a computer into it using a DVI cable and it will run it fine, but it will not accept analogue via DVI (for example plugging a computer in via DVI > VGA > DVI to lose the digital signal). When plugged in with an analogue signal, it just shows the same white screen as it does when it's not plugged in at all. This means that it must take the pure digital signal in a DVI cable.
It gets more confusing, though. I believe it has to do with progressive and interlaced scan. My HD 6950 graphics card is able to run the screen, and so is a crappy mac laptop (both using standard DVI ports). Computers output progressive scan, so I believe that the screen will not accept interlaced.
We have tried several boxes to run it. The first one gave random distorted signals (possibly faulty box? Or was it giving out an interlace signal?) to this screen, but worked on another screen. After returning that box, we bought another one which simply did not run the screen at all (same white as not plugged in) but also ran other screens fine. That box did not give out 1920x1080 in the specs or options, but also did not seem to put out either a digital signal or a progressive scan, so the big screen did not notice it. I have done more searching for a box, but had no luck.
Down to the question, I need an external TV tuner box (no HTPC) to run it, but it must output true digital DVI with progressive scan at 1920 x 1080. Another option is a series of converters or adapters that will make it work. What I'm trying to get is beyond my knowledge to find, so it would be awesome if you could recommend some things.
Thank you!
