kris_reynolds77I'm sorry kris, we missed this post. It wasn't intentional.
This can be tested by anyone that is interested in seeing if it's a issue across the board or not by using the website vsynctester.com. you can also use any of the .emu apps from the play store or another website called testufo.com/refreshrate.
They all give exactly the same figure on both my phone's of 59.8hz instead of 60.
Failing that, can someone point me in the direction of a proper site to submit bugs to seeing as no one from Asus acknowledges issues here?
