Seemingly my unit completely stopped functioning Gsync all together. MPO is unsupported, no matter what I do.
Wonder if my unit is faulty or something else going on, like the sleep related bug/issue but just permanent.

Are you guys seeing a bug with pulsar and vsync enabled causing much higher pc latency as reported by the nvidia overlay? For example vsync on with reflex caps to 320fps and the average pc latency bugs out and starts getting stuck at 12-14ms. Disabling vsync and setting in game fps cap to the same 320fps results in around 4.5ms average pc latency.
Is my monitor defective? Im using the acer version with the latest firmware, just asking in here since its by far the most popular thread.
edit; same experience someone had here with the asus version five months ago...

Does anyone here have the Acer model? I have a few friends who bought the acer model and one of them received their monitor today, did the firmware update and Gsync pulsar had some weird inverse ghosting artifacts and some other issues with ULMB 2 mode. Currently asked them to do a DDU driver wipe and reflash the firmware to latest to see if it fixes it but I'm curious to see if anyone else is having this issue on latest 1.1.8 firmware on acer. Also WOW acer's menus are a lot less intuitive than Asus and it's really hard to help anyone troubleshoot settings... can't even see what version of firmware you are on the acer one.
