"Generic Non-PnP Monitor" Acer S240HL Tri Monitor setup.
Hi all,
This issue really bugs me, every few months it'll happen, one of my three screens (9/10 times it's the Acer), will display as a "Generic Non-PnP Monitor", with this it'll only display in 640*480 (usually 1920*1080, same as the other 2 screens).
This set up works perfectly most of the time, and has done for the last few years, but as I said it comes and goes. I've done a lot of research online and the best advice I can find is that when it happens if I unplug it all, and let the capacitors drain in the monitor and GPU then when reconnecting everything it'll work fine. I've done this before and it's not worked, I've also done it and it's worked. I've also had it in the past where it's just reverted back to how it's supposed to be mid use.
My set up:
OS: Microsoft Windows 7 Home Premium 64-bit SP1
CPU: Intel Core i7 3770 @ 3.40GHz
Motherboard: ASUSTeK COMPUTER INC. CM6330_CM6630_CM6730_CM6830
Display 1: SONY TV (1920x1080@60Hz)
Display 2: Samsung S24B300 (1920x1080@60Hz)
Display 3: Acer S240HL (1920x1080@60Hz) <--- Displaying as "Generic Non-PnP Monitor (640x480@59Hz)"
GPU: AMD Radeon HD 7800 Series
I've got the latest drivers for all the hardware, I've got the latest windows updates for everything. I've tried older versions of the drivers for the GPU, no difference with the issue.
I've been to the Acer website to download a driver specifically for the monitor, but they haven't got one on there for this montior on this OS, just for Windows Vista (which Windows 7 won't recognize as an install-able file).
Any help would be much appreciated, this is driving me up the damn wall!!!
