I took a gamble and got a KOORUI 27 Inch Gaming Monitor, 2K Computer Monitors, QHD(2560 * 1440), IPS,1ms, FreeSync & G-Sync Compatible, 2x HDMI (It's so easy to return stuff to Amazon in the UK now, I wouldn't even have to lug it to the post office).

I was expecting the worse, but the gamble paid off. I'm very pleased with it. I'm not sure how accurate the rest of the specs are, but it does appear to be an IPS panel, all the PAL stuff I play scrolls silky smooth and I have yet to find a rate it wont sync to on the Mister.
