Alienware AW2521H questions

Post by theqq » 06 Jun 2023, 15:22

Hi, I have some questions and issues with AW2521H or possibly my setup, hopefully you'll be able to explain some things.
I'm running dual monitor setup with RX580 card, Alienware AW2521H and Benq XL2411Z; 1920x1080 on both.
1. Is ULMB not available on AMD cards? I thought it's just a monitor hardware technology, on 240hz and FreeSync off the option to turn ULMB should be available but it's greyed out.
2. There is no way to set 360hz on AL2521H when Benq is turned on, max I can set is 300hz. With Benq monitor off 360hz option shows up and is working without issues. Is that RX580 limitation or something?
3. Does FreeSync only work up to 240hz? I've tried to set it up with 300/360 but it just isn't working. Works fine up to 240hz tho.
4. Additional question about specific game - CSGO. When trying to run these settings:
FreeSync on
V-Sync on in-game
fps_max 237
I can see on OSD that hz is constantly floating around 210-237hz, is that a problem?
When setting fps_max to 0 OSD shows constant 240hz, without a single dip, should I just limit the frames to 237 in the AMD software or somewhere else since setting fps_max in game gives such unstable frames?

Let me know if you have any questions.
Thanks
