However, when I load up Photoshop I get this when I'm using the GPU for performance enhancing: http://i.imgur.com/GN2y4eU.png (both in 2015 and the latest 2017 version).
If the screen is minimised at all (say 3/4 of the screen) then there's a black border when I maximise. This also happens when I go into liquify every time (there's a 3/4 black "block" and I can only see a quarter of the screen). I zoom in and out, the black border remains the same size, so it's effectively cutting out the screen for me. I've changed my cache level to 8, changed cache tile size to 1028k (and every other variant) but it's still happening every time.
If I start in fullscreen, then it can work, but still repeats the same issue every time I go into Liquify. I've tried my google-fu and couldn't find anything apart from this query.
Here's an excerpt from my PS system info (not sure what's relevant here, so let me know if there's anything else I'm missing):

This has been with me for months, and I've tried every variant I can think of - I want to be able to use the GPU additions to boost my Photoshop productivity - any suggestions would be very gratefully received, as this has been so frustrating.
