I've had the 32" inch G7 for a couple of weeks now (FB02 model) and updated it to the latest Korean site firmware.
No problems that I can see with dead pixels etc. but I do still seem to get the odd flicker in wow classic (nothing major but it happens now and then).
I've not noticed in other games yet but need to try some more, as wow classic isn't exactly pushing the system it can hit very high refresh rates constantly so I wouldn't expect flicking there, but maybe it's just an issue with that game - it doesn't happen a lot and it's not severe, yet I wouldn't expect it at all other than during loading in when frames may naturally drop.
One question on display port cables for this:
I need to buy a slightly longer cable due to wanting to move to a desk mount instead, but all the display port cables I see only seem to be advertised at a max of 165hz at 2k, when DP 1.4 is supposed to be able to do 240hz at 2k.
Did manage to find one but it was a USB C / dp connection, rather than dp to dp type; not sure why this is so hard to find unless I'm missing something obvious here- any ideas?
