AORUS AD27QD - weird behaviour with 4K

[sewerino26]

Hello. I have an AORUS AD27QD. Its 1440P with 144HZ. But have upscaling to 4K and when i launch my first game on xbox one X i was able to run game on 4K. But now i dont know why when i am checking 4k in system settings it write THAT MY MONITOR not support 4K. So why on previous launch of game i was able to run 4K and now not?
