Hello all
First to make things clear. The projector is not visible in the divise manager, the nvidia controll panel or the windows screen resolution settings in the controll panel, so please no answers related to those unless their is some king of manual display recognition.
I have had this Optoma HD67 projector 2 years now and never had a problem until i formated my pc to Windows 8.1 pro and the projector simply stopped being recognised. I contacted with Optoma and they told my its more likelly an EDID corruption and because the projector has no USB A port for updating i should send it to Optoma for repair. Because that will cost too much and because i am tech savvy i tried to find out if there is a way to repair the EDID in another way. Turns out there is but i must have the projector's original EDID file which i don't and couldn't manage finding it anyware.
Afer a lot of troubleshooting i managed to get my projector recognised after installing the WDDM driver from microsoft. However i ve just formated my PC again to an UEFI version of Windows 8.1 and the projector refuses to be recognised even when i install the WDDM driver.
Projector cables and connections do work and are not the issue. Some laptops with their WDDM driver seem to recognise it as a generic display (Since EDID is corrupted) and some dont, which let me to suspect that there must be a way to force monitor discovery / recognition in windows 8.1.
Please help my found out a solution to this cause i m loosing my mind trying to figure this out!
I would be so gratefull if you guys could help me!
