Custom Resolution Utility (CRU)

[blutrache]

Is anyone using a DisplayPort to vga adapter with an AMD gpu? I'm having some weird problems with my setup, and don't know if it's windows related, gpu drivers or even mobo settings. Few days ago I swaped my gpu for a new one, I was using the native analog output of my older gpu w/o problems.
Thing is, all new gpus only output digital and one of my displays it's a CRT, exceding with ease the 1080p@60hz limit that most of these adapters are made for. I know the adapter is capable of doing the resolutions I'm trying to set, as I tried it in two different computers with nvidia gpu's and neither have the problems I'm facing.

Worst part of it, when I plugged in the adapter for the first time it worked fine at my desired resolution (1600x1200@85hz) for that day, until I decided to clean some parts and change the gpu to another PCI-E position. Then it all started to go wrong, to the point of formatting the whole system and keep having the same problem. This is how the program looks with a clean install,



That manual resolution it's quite different from the crt preset (or the gtf timmings), but that's what loads everytime I conect it to a new DP port. Then I fix the timmings and restart the drivers, but windows only list as max. res that 1280x1024.
It seems like I'm pixel clock limited, because any custom resolution lower than ~175mhz will work fine.

Manually chaning the .inf file didn't work out, neither did patching the drivers.
To my surprise, DP ports seem to have memory, so any changes that I do to the .inf file or CRU stays in that specific port.
