Fix:  Lower resolution to 1600 x 900.  Anything higher then 1600 x 900

I  only posted problems/fixes from personal experience. This happened a little while ago (between X2 and X2a) but I reckon would still be the case. Drove me nuts trying to tweak that nVidia card without success until somebody on the forum suggested to order a cheap ATI and stop wasting time. I can dig out the actual make of that non-functional card if it is of any interest, but it was one of the inexpensive nVidias ...

Well, shoot! Where were you when I needed you and that information?!?! Haha!   But seriously, this forum is such a rapid-fire bombing ground that it's almost impossible to keep up with all of the complaints, tips, tricks, complaints, rants, praises, more complaints and help.

[Just thinking out loud]
 
 
There just has to be more to the 1920x1080 issue than meets the eye... it's just too specific in that it's hosing you guys up, but others like me have no problem at all.
 
Is it just win 8.0, 8.2, or does it affect some Win 7 folks as well? 
 
In the past, too high a resolution could negatively affect some real-time processes as the GPU ate up too much memory I/O bandwidth, but hell, this is 2013! I'm running a 2 1/2 yo 2.4Ghz Gateway AMD quad with MB AMD graphics and and I can load it up (with plugins) till my eyes glaze over (metaphorically speaking..). You have to wonder if there is something wonky with the video drivers - because it's the same Sonar we all run. It's possible, but unlikely that CW stumbled into some unexpected O/S system level changes - those things are usually trumpeted loudly and in advance on MSDN...
