In Windows 8 Microsoft continue to make it harder to run un-signed drivers, including EDID over-rides, SLI hacks etc. A few people have had problems recently getting Doom III BFG running in quad-buffer 3D when using EDID over-rides, mainly users of CRTs and non-certified DLP displays.

One solution to these problems is to update the hardware EDID in the display itself, if you are lucky this will be a 5 minute job (but sadly some displays will require a hardware mod to work). PowerStrip can be used to update the EDID but it costs $30 and I couldn’t get it to work, so I used an old-skool DOS tool called DDCW instead:

You just need to convert the base EDID block from your chosen inf file into the correct format, then boot to DOS and flash it to the display, and prey your display’s EDID chip is not write-protected, thankfully my Acer projector wasn’t. In fact you only really need to change the Vendor / Product ID and the Monitor name string (descriptor block 3 in Phoenix editor) to fool 3Dvision, some useful conversion tools and info here:

Those with CRTs / non-standard 3Dvision surround setups and users of a certain Samsung screen might also find hardware level EDID updates useful.

Make sure you back-up your display’s real EDID data first, and don’t blame me if you fry your screen.

Good luck!
