Uncalibrated – Maximum Backlight Level
The H27E6 doesn’t have a zone dimming feature, so its brightness is the same whether you measure window or full field patterns. There is more than enough output here for any usage or environment, with over 474 nits coming from my sample. It’s also enough to beat the others save the Q27G4ZMN, which has a Mini LED backlight. It also bests the other IPS panels in the black level test for a superb contrast ratio of 1,505.3:1. That makes it an IPS class leader.
After Calibration to 200 nits
The H27E6 holds onto its IPS black level dominance after calibration with a solid 0.1414 nit and a final contrast ratio of 1,429.1:1. The ANSI result is extremely consistent at 1,413.6:1, which shows the high quality of its grid polarizer and of KTC’s quality control. Only a VA or an OLED monitor can do better than this.
Test Takeaway: The H27E6 is a standout IPS panel with plenty of brightness, excellent black levels and an honest 1,500:1 contrast ratio with consistent results in both static and intra-image tests. It takes good components and manufacturing control to achieve this and KTC obviously has both. This seriously ups its price/performance ratio.
