I'll test as many resolutions as I can today and update the DR...ran out of time yesterday. Unfortunately I can't test many TH resolutions since I'm currently using mixed aspect monitors that share very few common resolutions. I was thinking of ordering more 16:9 panels, but with all the cool curved screen stuff going on at the moment, I believe I'll wait. I also can't test 16:10 resolutions short of forcing my 16:9 TV to one, but then I can't really say if there's any issues with it since I'll have stretching anyway.
On a side note I had a dream last night of this game on a table made of multiple 4K displays and Kinect hacked touch control. I'm assuming that sort of dream is commonplace here
Edit:
I could only test 1280x720 and 1360x768 natively (they both work fine, however an http 500 error is stopping me updating the DR right now, and in fact posting this). This made me realise that the only TH resolution I could test wasn't exactly native, as this stretched across my center monitor.
I could give temporary Steam account access to any of you if you'd like to fill in the gaps (judging by the how-to vids, I'm guessing Skip could cover them all quite quickly?).
