Is it an acceptable backlight bleeding?

i wouldnt accept that a little bleeding is fine but thats like a few millimeters too much

I would consider initiating an RMA for that much.

On a completely new monitor? Heeeeeellllllll noooooooooooo.

i dont get that with my old Sony EX what ever it is now )5 years old and no one damn problem with it sadly no excuss to upgrade).

id take it back if i were you.

I'd say that's a bit too much for a brand new TV. That's the kind of thing you expect after a couple years of use.

If its like that brand-new, out of the box, what's it going to be like in a year or two?

I have the same screen and I had the same problem (mine was less noticeable though) until I adjusted screen settings (was still there but only visible if you put your face at 150degree 3 inches from the screen during a complete black screen)... I noticed that brightness was at 100% so I lowered it at 75 % (100% on this screen is just too much after a while your eyes will be tired...) I also put HDMI Black to normal instead of low (this is required if you want to use extended RGB instead of limited... But you will need to enable extended RGB in nvidia control panel if you have a nvidia card)... Otherwise it is a great monitor price/quality wise...

I would RMA it it's going to get worse the longer you use it, even quicker with 100% brightness and full backlight brightness.

Pretty normal to get more backlight bleed with IPS/PLS monitors I'm afraid, it's their own drawback...so I'd say that's normal.

My own ASUS PB258Q has backlight bleed at both bottom corners and the model PRAD tested had the same issue. I rarely notice it anymore though.

Muhahahaha....Blooooodd !!

I'd say return it. If it is that way brand new, it will most likely get much worse as time goes on.

That needs to be returned. From the picture I'd say the monitor had been damaged as that's an obscene amount of backlight bleed for the type of monitor, and the shape of it implies impact damage to me, which I feel is supported by what looks to be half a dozen or so stuck pixels as well.
Return that shit ASAP and make them send you back a proper monitor.

Thanks everyone, I appreciate! I think I'll try Samsung support and see what they answer me. Too bad, I wanted it to be perfect on the first try :(

I would return it as well, if you brought it at store it might be a more quick process.

If returning is not too cumbersome for you, by all means, do it. That's the only way companies are gonna up their quality standards.
