Uncalibrated – Maximum Backlight Level



I modified my test procedure in the 34M2C7600’s case to show its full potential. Out of the box in SmartImage mode, it peaks at just under 500 nits with a respectable 2,727.5:1 contrast. But in Game 1 mode, with the brightness maxed and no other adjustments, the peak is much higher at 740 nits with contrast at nearly 4,000:1. This is a much better state of affairs thanks to the lower black level.
After Calibration to 200 nits



I couldn’t calibrate the RGB sliders because there aren’t any. But I changed the gamma to 2.4 and chose the Preset color temp to get a slightly higher contrast. You can see that all the panels have excellent native contrast. It’s a bummer you can’t use the 34M2C7600’s local dimming because it would add a lot of punch to SDR content.
Quality control is excellent, which is indicated by the Philips’ high ANSI contrast value of 3,315.9:1. Despite the lack of an SDR zone dimming option, the monitor looks fantastic with deep blacks, bright whites and plenty of color.
