TL DR: Some people are going with the ASUS because of SDR brightness being higher (450 vs 200), less (or none) aggressive screen dimming and no 4k input firmware bug. The resolution bug can be fixed via CRU but you have to remember to do it every time you update your drivers or you will end up launching a game, getting the dialog on screen telling you "your resolution is set to 4k, please set it to 1440p" and then having to do the whole CRU fix.

The screen dimming can be "fixed" by turning off the Smart Energy Saving but this isn't recommend on OLED's for obvious reasons AND it voids your warranty if you do this. The main issues are the aggressive screen dimming and 4k resolution output. The LG also has other issues that LG still hasn't commented on and I dont have faith in LG to fix the issues if they cant even acknowledge them. I am coming from a PG279Q and the main reason im replacing it is because the backlight is dying so I have 2 bright spots on the edge which sometimes completely go dim or stay bright.Īsus advertises 450 nits versus LG's 200 and thats enough for me. I've had the LG for almost a month and I am returning it because I need the brightness at 85 with contrast at 80/85 to be comfortable.

Not every game supports brightness and windows 10 in HDR is mediocre. All the talks I've seen online is the SDR brightness. It only happens at 390hz because at 360hz it is fine with no flickering.I would say SDR Brightness. It stops flickering when I turn off the monitor, but when I turn it on after 1 min it starts again. I thought it fixed it then after 1 min it started flickering again. The PG279Q has a 'disable deep sleep' option that this monitor does not have. Also happen to own a PG279Q that does not do this. I purchase the club3d displayport cable that was recommended here. Best Buy can get it in a week, Amazon start of July, and Microcenter has 10+ in stock locally and available to ship. That worked fine for me because I don't use GSYNC anyway. It was fixed by disabling GSYNC and updating the drivers.

However, on my other 240 Hz monitor I was having flickering issues when a GPU-accelerated application was open. I have been running the monitor for months using a third-party cable and have had no issues whatsoever. I would say it's either the cable or a GSYNC bug. I am currently using a XL2546k without any problems. It happens a lot when I have a browser open.

I went to microcenter and replaced it with another one and it is still having the same problem as in the video. Hi, I purchased this monitor at microcenter and having the problems like in this video where the monitor keeps going black screen on and off.
