The flaw is here:
Have three external monitors off a Dell Inspiron laptop (one monitor via a USB docking station)
Your graphics configuration is crooked and you are exhausting all the resources. You will have to unplug at least the USB monitor and adjust your screen resolution and other graphics parameters. Also refer to this:
Thanks Mylenium. I unplugged the USB Monitors and still get the same message about the Open GL. How do I open it? Is there a setting somewhere?
After unplugging the USB monitors, did you relaunch Photoshop and reset Open GL prefs in Photoshop Preferences > Performace> Use Graphics Processor ?
I had this problem too with my gpu drivers and PS updated and thought I tried everything. What did the thing was resetting all the settings to default. If you have synced settings from previous PS installation this most likely will fix the problem. This is how to reset received from this Adobe help page: Photoshop CS6 GPU FAQ
Resetting preferences returns OpenGL settings to their default status. Reset Photoshop preferences by pressing and holding Shift+Ctrl+Alt (Windows) or Shift+Option+Command (Mac OS) immediately after you start Photoshop. Click Yes when asked if you want to delete the Adobe Photoshop Settings File. Retry the function that caused the problem.
If this doesn't work try deleting your settings (.psp) files from AppData folder C:\Users\[Username]\AppData\Roaming\Adobe/Adobe Photoshop CSx\Adobe Photoshop CSx Settings\
Worked for me, Thanks
