So I recently aquired a Sansui SLED2453w monitor, and it ran fine for a little while, but now it's set to a resolution of 1280x1024, and is labeled as a "Generic Non-PnP Monitor". This resolution is OKAY, but it's the highest that Windows is allowing me to choose, without saying it's unsupported. I had it running on a above 1700 resolution when it worked. I've tried updating it's driver, "detecting" it, and a couple other methods.
I've, of course, unplugged it and reconnected to no avail.
Is there something I'm doing wrong? Any help is thoroughly appreciated. Thanks for your time.
