Hello Toasty.

I have some data for you. Maybe its considered here or not. I also had a "Highest measured interrupt to process latency" about 24.000.
Could it be anything to do with your patcher?

No, the patcher only makes simple changes to pixel clock limits.

Quote:(...) I need a serious support after I totally screwed up my GC or monitor after I played with NVIDIA Pixel Clock Patcher and CRU. (...)

I'm not at home for a few weeks, so I bought an Asus PB278QV monitor for my needs, as a graphic designer. I plugged it through HDMI on my older GTX260. Then I got a 1920x1080 resolution instead of its native 2560x1440 resolution. Nothing to do, the problem is surely the HDMI output of the graphic card and I do not have, and can't get, a DVI cable.

I got the idea to use your PCP and CRU's utilities, hoping it may solve the problem. I did it following carefully your instructions, on Win10, updated Nvidia drivers and stuff. Then I got a nice "HDMI No signal" message, anyway all is screwed up. I rebooted in Recovery mode then reseted and restarted still following your instructions to revert it all. After hours of tweaking, I'm now writing to you from a 1200x800 resolution, Nvidia and monitor's drivers uninstalled , after tried everything I could.

If it helps, here a screenshot of the current status of CRU : imgur.com/ODjwTtv

Quote:(...) When exactly did you start getting the "No signal" message, after using the patcher or after using CRU? The patcher requires a 400-series or newer GPU. It has no effect on 200-series GPUs, so that shouldn't have done anything. What did you change with CRU? Running reset-all.exe in safe mode and rebooting should have reset anything done with CRU. You can also try using DDU to completely remove the NVIDIA driver, which will also reset all monitors: wagnardsoft.com/display-driver-uninstaller-ddu


DDU worked fine, thank you very much for your help ! What I did :

  1. Downloaded the last drivers from NVidia website
  2. Rebooted in Safe Mode, disconnected from internet
  3. Selected "Clean & Reboot" option
  4. Rebooted in Normal mode then launched Nvidia Installer
  5. Approx. after 20s, the screen gone black and... I got a beautiful blue "HDMI No signal" message...
  6. Waited about 3-4mn (the installer may be paused, stuck or running slowly), still black screen/No signal...
  7. Fortunately, I found in the meantime in the basement a crappy old 27" Samsung monitor
  8. Connected the HDMI cable, then Hooray, I finally got an image ! The installer was apparently stuck.
  9. Reconnected to my Asus, all is working fine now...



But I'm still stuck in 1920x1080 instead of the native 2560x1440 resolution. I assume now that the HDMI output can't handle such resolution, even at a lower frequency (I tried at 60 and 50Hz). If you have any idea how to resolve the problem, I would be very grateful Smile

Take care, Helvetica.
