Custom Resolution Utility (CRU)

Just upgraded to Windows 10, I can't get it to work with 2560x1440. Tried CRU, it still doesn't do it. Any thoughts?

CRU doesn't support Intel GPUs. CRU uses EDID overrides, and Intel's driver doesn't currently support EDID overrides. You'll have to find some other way to add custom resolutions such as through Intel's control panel, but the driver might not let you add 2560x1440 @ 60 Hz without the proper EDID because of bandwidth restrictions even if the hardware is capable.

The more complicated solution would be to use a hardware EDID emulator that can be programmed to use the EDID you want, but those are expensive. Supposedly it's possible to build your own pretty cheap, but I don't have information on how to do that. You might want to talk to Haemato because he just talked about doing that two posts before yours:

The board is simple - just HDMI in/out with the i2c lines intercepted and connected to an EEPROM. I created a custom EDID that only has the timings I'm interested in and programmed that into the EEPROM.

I've got one board so far and tested it out. The projector came up at 1280x800@120Hz as it should. I need to get 2 more boards now to try out Surround. Hopefully by Friday. Waiting for nvidia to fix their shit is futile, it's been broken for years now.

*note* much thanks to my friends that helped with the board
