My test database had no 25-inch QHD screens, so I rounded up the latest 240 and 180 Hz 27s to compare the P2510S’s performance. The group is RCA’s M27PG135F, HP’s Omen 27qs, ASRock’s PG27QFT2A, Asus’ XG27ACS and AOC’s CQ27G3Z.
Pixel Response and Input Lag
240 Hz monitors typically refresh in four or five milliseconds. The P2510S is the former group. It has an extremely precise overdrive, so at 240 fps, there’s almost no motion blur. The best part, though, is its extremely low input lag. The P2510S is one of the fastest gaming monitors I’ve ever tested with just 16ms of total lag. It’s quicker than the Asus PG248QP which runs at 540 Hz. Major wow!
Test Takeaway: The P2510S is more than qualified for gameplay at all levels from casual to competitive. Though a higher refresh rate, or an OLED, will render slightly better motion resolution, those displays won’t be as responsive to control inputs. In fairness, this difference will be hard to perceive by all but the best players. But it is significant that there are only two monitors in my database that are quicker, Alienware’s AW2524H at 15ms and Asus’ PG32UCDP, which hits 11ms in its 480 Hz FHD mode.
Viewing Angles
Most IPS screens go a bit green when viewed at 45 degrees to the side but the P2510S has a red tint. This is a good thing because the shift is less visible in actual content. Brightness drops by around 10% and there is some loss of shadow detail. The top view is 50% less bright, looks cool in tone, and has a similar reduction in shadow detail. Overall, this is very good performance in this price segment.
Screen Uniformity

My P2510S had a slight glow on the left side of the screen when I observed a black field pattern. It was subtle enough that content wasn’t affected. This is a sample-specific issue. Others may measure better than this.
