0.5 ms monitors likely comming next year.

Currently all 240hz monitors are using panels that were not intended for 240hz.

0.5 ms may sound insignificant but to those who use them including the pg258q that owl used, they know they do have a bit more motion blur than many expected. 1.0 ms rating is actually a best case transition and average transition times for 240hz monitors are around 3.5ms or higher which are a significant portion of the 4.16 ms frame time.
Look for new monitors advertising 0.5 ms in 2019.
