Uncalibrated – Maximum Backlight Level
The Y25-30 delivers a bright and punchy image with nearly 400 nits peak in SDR mode. There is more than enough light available for any usage environment. Black levels are typical of average IPS panels, which results in just under 1,000:1 contrast. As you’ll see later in the color tests, gamma is a tad dark, meaning you can operate at a slightly higher peak level.
After Calibration to 200 nits
With the backlight set to 200 nits, leveling the playing field, the Y25-30 maintains consistent contrast. I only changed the blue slider in the user color temp with one click. I experimented with the gamma presets to lighten the image a bit, but one click made it too light. The default gamma looks best.
ANSI contrast is reasonably close to the static number at 928.4:1. Since the Y25-30’s screen uniformity is solid; this is an expected result. There are no quality control issues here.
Test Takeaway: The Y25-30 has contrast that’s average among value-oriented IPS panels. The dark gamma helps a little by allowing the user to set a higher brightness without creating a harsh image. It’s also good that there is a wide gamut though, that is common to most monitors today. The Y25-30 also has high brightness, which will appeal to users in brightly lit environments.
