Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Reasonably small input lag
Complete input lag time (signal delay and pixel response time) is 11.85ms or ¾ of a frame.
Pro Comes excellently calibrated
Pro Good color temperature uniformity
According to Spyder4Elite tests performed by PC Monitor, P2415Q has good color temperature uniformity. A DeltaE deviation of over 3 can be easily noticed by most people and the highest deviation recorded is 2.5. It's worth noting that the monitor has an uniformity compensation setting that in the same test proved to make things worse with a maximum deviation of 2.9.
Pro Impressive contrast
According to tests performed by PC Monitors, P2415Q set to factory defaults (75% brightness, Standard preset) produces luminance in the range of 0.21 - 237 cd/m² with a contrast ratio of 1129. It provides good brightness and dark blacks. It is also capable of going up to 0.30 - 331 cd/m² with a contrast ratio of 1182 at 100% brightness.
Pro Cover all of sRGB color gamut
The monitor covers all of sRGB space and with some calibration is capable of representing the colors accurately.
Pro Good contrast
Pro Smooth surface
Among the least grainy matte surfaces available for UHD monitors.
Pro Low input lag
Complete input lag time (signal delay and pixel response time) is 6.85ms or under ½ of a frame.
Pro Can automatically shut down when you're away
The monitor has a proximity sensor that allows it to be automatically set to standby mode once you're away from the monitor for more than 40 seconds.
Pro Can auto-adjust brightness throughout the day
Can be set to automatically adjust brightness due to the built in ambient light sensor.
Cons
Con A maximum refresh rate of 60Hz can be a concern for some
A 60Hz monitor, while sufficient for most people in most cases, can still cause issues with fast-moving objects on screen. It's especially important with things like gaming where the ability to react to events happening on the screen quickly is important.
Con IPS glow
IPS glow is the light on the sides or corners of the screen that can reduce some of the peripheral detail.
Con Somewhat too grainy texture surface
Con A maximum refresh rate of 60Hz can be a concern for some
A 60Hz monitor, while sufficient for most people in most cases, can still cause issues with fast-moving objects on screen. It's especially important with things like gaming where the ability to react to events happening on the screen quickly is important.
Con AHVA glow
AHVA glow is the light on the sides or corners of the screen that can reduce some of the peripheral detail.
Con Poor dynamic contrast implementation
Dynamic Contrast is an optional feature meant to increase or decrease the back-lighting depending on scene that is displayed in order to get higher dynamic range. Unfortunately, the implementation tends to slightly overshoot on highs regardless of the settings used.
Con Some color temperature uniformity issues
According to Spyder5Elite tests performed by PC Monitor, BL2711U has color temperature issues that can be seen with the naked. A DeltaE deviation of over 3 can be easily noticed and there are deviation of up to 3.8.
