I have it. Absolutely love it! I do more night flights now, than I would ever do with my 43 inch Philips IPS monitor. True Blacks, which is what OLED is all about.
Make sure you’re running on the latest firmware for the monitor (F06 I believe), turn G-sync on, and in the sim options, run it at 50% refresh (for 60 FPS max). Yes, it has a 120hz refresh rate, but in night flying there is a flicker that is noticeable when the sim goes over 60hz. This may be addressed in a future FW update. There is a reddit post on how to update the FW and avoid issues, as Gigabyte instructions are a bit vague.
Being an oled there are certain precautions you may want to take- loads of YT videos and tutorials out there on how. I’ve had mine for over 4 months and average over four hours a day, and have zero burn-in issues for the record.
The monitor does have built-in protections, but some people get confused as to how they work. The monitor has a standby mode when the PC is shut down. My advice is leave it in standby, otherwise the pixel refresh routine, gets prompted too frequently. Leave it in standby, and only turn it off, when the monitor itself prompts you to do a pixel refresh routine, which is every four to six hours of use. It takes about 5 mins, and when the standby light is no longer flashing you can turn it on again.
