Whew, I spend quite a bit of time trying to debug this and I finally found this post.
Yes, I am having the exact issue you have described in your post with my ASUS SWIFT. I had this monitor since launch but I primarily use my DK2 with my work computer. This is the first time I used it in my gaming computer.
Computer Specs: Intel i7 3930k 32GB DDR3 NVIDIA 780ti ASUS Swift Primary Dell U2711 Secondary (running off of a 2nd slave card non SLI) DK2 off of the HDMI port on the 780ti
SWIFT is running 120hz on the desktop, 144hz for full screen gaming with G-sync enabled
I was getting this issue with the demo scene using Direct Display mode. I had to switch to Extend Desktop mode to get it to display correctly. I am using an Asus ROG SWIFT PG278Q as my primary display.
Unfortunately that only partially fixed it for me.
When I have it in extended display mode, it will not actually maximize the program. It will only do a windowed full screen and display the dual eye oculus view as it would look like on the desktop. Not proper full screen split image for each eye.
ROG SWIFT PG278Q Here , Exactly the same problem ,
on top of that I also have a problem with Colors ( i am not sure if I should call this Chromatic aberration failure or not ) because am a noob and I dont know what that is exactly.
But Last night , I hooked up the DK2 to try Radial-G (steam early access) , updated to the latest runtime /SDK and Nvidia latest Geforce drivers , also updated the firmware of the DK2 because i did not use it for quite some time.
after all that I got the Chromatic aberration failure thing ,, I see Red , Green and Blue pixels every where , specially where there are any lights , and the colors seems to be completely wrong .. blue is orange and black / grey is green .
on top of all that , the screen is also shifted to the right.
Yes, I also have the ROG Swift with the same symptom. Disconnecting it and using a regular monitor allowed me to use the direct mode for Sightline: The Chair with the DK2, so that's helpful as a workaround for now.
