didn't see nothin in search: benq xl2540 teardown instructions?

[Felicity]

got bored today and wanted to try looking inside the panel for fun and to maybe clean out whatever dust got in there. got the four screws on the back off. took my blinders off since I can't game with more than 90fov irl of course.
now I'm kind of lost. I just have the panel on a bench and I don't know how to get the plastic shroud off. in the older tutorials it looked really easy for past benq monitors you just sorta pulled it off or plied it off.

the manual ofc won't help me here so anyone done this and can advise me safely on how to take a peek inside
