This sure sounds interesting. The reign of AUO M270 IPS is about to end this year? Maybe even with better QC?
http://www.tftcentral.co.uk/news_archive/39.htm#panels_lgdisplayFor gaming there are some exciting developments as well for high refresh rate IPS panels. The 31.5" LM315WQ1 is expected to go in to production in December 2018 and will offer a 2560 x 1440 resolution with 165Hz refresh rate. This panel also offers a 1000:1 contrast ratio, 350 cd/m2 brightness and 98% DCi-P3 gamut thanks to the Nano IPS panel.
In the 27" space is the forthcoming LM270WQA panel, with a 2560 x 1440 resolution and 165Hz refresh rate. This also offers a 1000:1 contrast ratio, 350 cd/m2 brightness, sRGB gamut. It's not expected to go in to production until December 2018.
There is also talk from LG.Display about improvements in their IPS response times, reportedly trying to improve on the current 5ms G2G, pushing down down to 1ms G2G with higher levels of overdrive. It remains to be seen how successful this is in practice, and how much overshoot gets introduced but an investment in driving response times to accommodate higher refresh rates properly is certainly welcome.
