I plan to buy the ossc for my retro pcs. I would like to cover the 90s, dos/windows, but my modern monitor does not have analog input.
It looks fine for the vga input, but i did not find too much information about the higher, and the trickier vesa resolutions. Many demos uses special vesa modes, eg 512×384, 400×300, and i also would like to use for windows with 1024×768.
Someone more knowledgeable can correct me, but I expect the OSSC would digitize these resolutions just fine; however, I’m not sure that the 512×384 or 400×300 modes would be recognized by your monitor. The OSSC might be able to line-double 512×384 to 1024×768, but 400×300 is more of an oddball.
I have an old PC in the garage that I could test your use case with. What version(s) of DOS are you running, and which games?
The OSSC will handle higher resolutions as pass through, but does a great job. 1280×960, 1280×1024, 1280p, 1080i/p – I’ve tested them all, all work great, and splitting the signal directly to a low-latency PC monitor or through the OSSC to a separate low-latency HDMI screen, there is no input delay.
