Is 4K at 240 Hz worth it on a 27-inch screen?

It gives very sharp detail and smooth motion, but at this size you will likely use display scaling for desktop work. For games, the combination is a clear step up from 1440p high-refresh panels.

Does it work well with a PS5 or Xbox Series X?

Yes. It accepts 4K over HDMI and supports FreeSync Premium Pro, so consoles can use their high-refresh modes. Check that your console cable and settings are set to the highest output.

Is the brightness enough for a bright room?

At 250 nits it is fine for dim to normal rooms but can look dim in strong daylight. OLED contrast helps, yet a bright window behind you will wash out the picture.

Should I worry about OLED burn-in?

Static elements like HUDs and taskbars left on for long sessions are the main risk. BenQ adds a graphene film for panel protection, but varying content and using screen-off timers still helps.

The monitor, a stand, and the usual cabling for its HDMI, DisplayPort and USB-C inputs. Confirm the exact cable bundle with the seller before ordering.
