There won’t be any comparisons for my review of the PD2770U. I tested it in its out-of-box state using the most common picture modes. It’s all about color accuracy so response and lag tests carry less weight given the monitor’s design intent.
Pixel Response and Input Lag

· Response Time Full black to white transition – 8.1ms
· Absolute Input Lag Full black to white transition – 24.4ms
The PD2770U is a 60 Hz monitor without Adaptive-Sync or overdrive. It isn’t suitable for anything but casual gaming but it isn’t the slowest monitor I’ve encountered. In the LDAT test, it drew the one-inch square in 8.1ms from black to white. Though there is motion blur, it isn’t enough to distract in slower-paced games like Myst. Just don’t try to engage in a fragging session; it won’t be pretty. The lag score is surprisingly low at 24.4ms. If you do play a shooter, the PD2770U will respond quickly to control inputs.
Test Takeaway: Gaming content creators might want a monitor with Adaptive-Sync and a faster refresh rate than the PD2770U. But it does a decent job with control inputs thanks to surprisingly low lag.
Viewing Angles

The PD2770U has average off-axis image quality when compared to other IPS monitors. The side view is a bit red in tone with no significant change to brightness or gamma. Though you won’t be likely to share a 27-inch monitor, it can be done if needed. The top view is a tad blue with reduced gamma and brightness.

Screen Uniformity

· Screen Uniformity Deviation From Center 0% Black Field – 10.18%
To measure the PD2770U’s uniformity, I switched each picture mode to Brightness First. The default is Uniformity First and it reduces brightness by around 30%. Uncompensated, a score of 10.18% is about average for the IPS monitors I’ve tested. The meter noted a hotspot in the lower right corner, but I could not see this in actual content. With compensation turned on, the score dropped to 4.31%, a barely perceptible difference.

Been using one of the BenQ PD's at work and they're really amazing, if you work a lot with graphics. The resolution is crystal clear and the colour setting options are really useful.
