I didn’t receive a display port with the monitor. Is this normal?? How am I supposed to connect it without a display port

Also didn't get a display port cable, submitted a claim and got $20 refunded

is this 280 hz or 240? all things I see are saying this is 240 but obviously the page says its 280.

I've bought it and was able to set it to 280hz so yeah it's 280.

Does it supprt vrr or ALLM?

Yes, it supports AMD FreeSync Premium Pro technology, which includes variable refresh rate (VRR) capabilities.

Can you put it on a mount

Yes, it is VESA compatible and mountable with a 75 x 75mm specification.

is it matte or glossy
