How to Calibrate Redmi 4K Monitor A27U with Detailed Parameters for Best Display

🎉 Finally, I had some free time during the holidays to align the color settings between my Redmi A27U and Mac! 🎉

Previously, all the guides I found online were for the older Redmi 27NU models. 😅 The built-in parameter modes are completely different and don’t apply to the A27U. I was totally confused and even thought I might have bought the wrong monitor! 😂 Eventually, after spending some time tweaking it myself, I got a result that looks pretty good. So, I’m sharing it here for everyone’s reference!

🌟 **Step 1:** Connect your Redmi A27U to your Mac using the monitor’s built-in Type-C cable. Then, plug in the power cord and turn it on.

🌟 **Step 2:** Adjust the settings on your Mac desktop to configure both displays.

🍎 **For the Mac internal display:**
– Preset: Apple Display (P3-600nits)
– Refresh Rate: ProMotion
– Turn off “True Tone” while calibrating—it makes the process easier. Once everything is set, you can turn it back on if desired.

🚀 **For the Redmi external display:**
– Font Size: Larger Text
– Color Profile: Display P3
– Refresh Rate: 60Hz
– Orientation: Standard

🌟 **Step 3:** Fine-tune the internal settings of the Redmi A27U monitor.

🌸 **(Note:** The power button and calibration button are the same, located on the lower-right back side of the monitor—check the last photo for reference.)

🌸 **Pro Tip:** The Redmi monitor doesn’t automatically adapt to ambient brightness, so it’s best to make two sets of adjustments—one for night and one for day:
– **Nighttime (dim lighting):** Set brightness to 50, hue to 42, and saturation to 48.
– **Daytime (bright lighting):** Increase brightness to 80, adjust hue to 46, and saturation to 50.

🥳 That’s it! These are my personal tips for calibrating the colors on the latest Redmi 4K monitor. I hope this helps anyone else who’s just gotten their hands on a Redmi monitor! 🌟
