Yeah not sure why that was not 50.000 there, that screen was from when the drivers didn't even acknowledged the display as 1440x2560 at all (luckily that is fixed now). Pretty sure it was automatically changed. Unfortunately it does not make a difference, radeon software still insists the LCD is incompatible with these settings, which is plain wrong. My other machine managed to drive the LCD just fine with these settings...

Visual glitches still there, btw I can't expain why it works at all (minus gitches, flickering, etc) given that the timings are competely wrong...
At this point it clearly seems like a radeon driver issue, but I can't seem to get help over at the radeon forums. Any tips? Thanks!

For some reason it's using the GTF standard instead, which matches the "Old standard" timing parameters with CRU. What happens if you make any changes with CRU? Try deleting all the detailed resolutions in the extension block since they're just duplicates.
