From what you're telling me, it's actually reading the overrides, but Surround is not handling the resolutions correctly. If you're using HDMI, try adding an HDMI support data block in the custom extension block. After enabling Surround, try rebooting to make sure the settings are saved. The center screen remaining black with artifacts at the top almost sounds like a video card memory retraining issue. Try increasing or decreasing the vertical total and see if that makes any difference. Other than that, I have no idea. You'll have to bug NVIDIA to fix these problems. Ok, I'll try that. What does the HDMI support data block actually do? Does the driver infer more or different resolution support as a result? There seem to be some nvidia driver issues with resolution selection so I wanted to restrict the number of resolution possibilities as much as possible. The other solution I've got in the works is to create an EDID interceptor board that goes inline to the projector. 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 |
