Uncalibrated – Maximum Backlight Level

One of Mini LED’s principal features is high peak brightness. This is great for HDR content because it makes highlights pop. But it can be good for SDR too if you have a bright work environment with sunny windows. The G Pro 27i is perfect for this with a peak SDR white point of over 940 nits. This is from a full-field white pattern, and it is searingly bright.

That means a high black level too, but the resulting contrast is almost 1,300:1, which is above the IPS average. You can broaden this by turning on the local dimming. There is no downside to this because all shadow detail is retained, there is no clipping. Even on the low setting, I could not measure the black level so the G Pro 27i’s dynamic contrast is theoretically infinite.

After Calibration to 200 nits

With local dimming off, I adjusted a full white field pattern to 200 nits. This puts the G Pro 27i’s black level on par with the other IPS screens and contrast remains consistent at 1,276.4:1, excellent performance. The ANSI test was also consistent with only a tiny reduction in value, 1,160.2:1. Among IPS monitors, it doesn’t get much better.

Test Takeaway: The G Pro 27i delivers the same excellent contrast performance as other Mini LED monitors for less money. It’s one of the best-performing LCD panels I’ve tested at any price. It has an effective local dimming feature that can be used for SDR content that takes contrast to a very high level with no downside.

    Does the Monitor support HDMI pass through? Is it eARC?

    It's a monitor, so eARC is likely not a thing. That's 100% a TV-to-reciever/sound bar feature.

    HDMI was built for that reason, yes, but eARC specifically is complicated and requires a bunch of handshakes to work. It's really intended to simplify HT setups. HDMI does still pass audio on PC, but to my knowledge most monitors don't do eARC because they're not sending audio signals to other devices, unlike Smart TVs.

    Now bring a 32" 4k version of this monitor and it will be awesome.

    CON : No USB ports or internal speakers

    Not for all, some people don't like to have cables cluttering up their monitor. I myself do like using a monitor for KBD & MSE with a single pass back to the computer, but don't miss internal speakers which are normally poor quality.

    Xiaomi's own FAQ states the monitor does not support VRR, but VRR seems to be working fine according to this review. Can someone clarify?

    Hello, I can't find anywhere if the monitor is Flicker-Free (doesn't use PWM to control brightness).
