Since trimming down the bezels is no longer a mountainous task for phone makers, they are now looking to offer a higher refresh rate display to perk up the experience. If you’ve tried out a smartphone with a high refresh rate – say the OnePlus 7 Pro or Razer Phone 2, then you would know how smooth and fluid it feels. Well, if you’re looking for something similar on the Redmi K20 or K20 Pro which you may have recently bought, then it’s now possible.
Thanks to the developers over at XDA, they have found a way to overclock the standard 60Hz display on the Redmi K20 series to 75Hz. Yeah, they’ve come up with a mod which when installed on either of the K20 devices will bump the refresh rate to 75Hz.
You can find the 75Hz overclock mods for the Redmi K20 and Redmi K20 Pro right here:
- Redmi K20 75Hz mod (hardcoded for now; suggested to be used only with MIUI.eu stable version 10.3.12)
- Redmi K20 Pro 75Hz mod (pretty stable; works well with China stable, China dev, & Global/Indian ROMs)
Note: This is not an official mod and could cause harm to your Redmi K20 or K20 Pro’s display, so we suggest you install it at your own risk.
The process to install the 75Hz screen overclock mod is fairly simple. You will, however, need to have an unlocked bootloader to get the mod running on your Redmi K20 or K20 Pro. If that’s the case, you first need to make a backup of the DTBO partition via TWRP custom recovery (for those using it) or the Lanthanum System Toolbox. Now, there are many different methods you can use to flash the mod on your device and upgrade to a much smoother experience.
While many users who have tried out a similar mod on the Mi 9, which overclocked the display to 84Hz, haven’t faced any issues expect for degraded battery life – which sure comes as no surprise. However, you’re only slightly increasing the refresh rate, so it is possible that the battery life won’t really take a huge hit.
There is currently no toggle to switch back to the standard 60Hz refresh rate and you’ll have to flash your backed up DTBO partition file for the same. A Magisk module for the mod is also in the works, so stay tuned for improved support in the coming weeks.
