nvidia driver fails to detect native resolution of the monitor.

My monitor’s native resolution is 1366x768, yet the driver only offers me 1368x768, which induces some stretching artefacts on the monitor and some annoying blur waves (some flickering horizontal bands that have the image blurred)
I’ve tried fiddling with the EDID data to get it working asking on this thread for help but so far nothing worked.

Please follow the instructions in the sticky post about how to generate and attach an nvidia-bug-report.log.gz file. That said, there was a limitation in certain older graphics cards that required the screen width to be a multiple of 8. If you’re using a GPU old enough to have that limitation, then you’ll need to consider upgrading it.
