Get 120Hz Refresh Rate with WQHD+ on Galaxy S20/S20+/S20U

Back in February 2020, Samsung launched its flagship series Galaxy S20. All three phones are very high-end and are true flagship phones with all the bells and whistles of a flagship phone. however, the user’s biggest complaint about the S20 was that they couldn’t use their phone in 120hz with QHD resolution. Samsung has capped its software to run 120hz only on FHD mode and if users want QHD then they have to shift to 60hz. But, after a few months, we now have a solution through which we can get 120hz with QHD on the S20 series. It will work for all three smartphones of the Galaxy S20 series. that is S20, S20+ and S20 Ultra.

Do note you have to do some tweaks to get 120hz with QHD on S20. First, let me clear you that if your phone is running on FHD+ then the resolution of the phone is 2400×1080. And if you change it to WQHD+ then the resolution is 3k which means 3200×1440. Since Samsung officially doesn’t support WQHD+ with 120hz. The tweak will work with a 1 pixel less than what WQHD+ has That means you will be able to run your S20 on 120hz with 3199 x 1439 resolution. Which isn’t bad either and the difference is 0 between 3200×1440 and 3199×1439. For reference and confirmation check the below screenshot to show it works even on the Exynos S20 series.

How To get 120hz With QHD on S20

  • Make sure you have ADB installed on your PC, if not then get it from here.
  • Now enable USB debugging from the developer’s option on your Galaxy S20.
  • Also, make sure that your phone is currently running on FHD+ with 120hz.
  • Connect your phone to the PC.
  • Make sure from the phone you have selected image transferring from USB settings.
  • Now Open ADB on your Windows PC.
  • Type ADB devices. Click on Allow on your phone if prompted.
  • Now type adb shell wm size 1439×3199 (Don’t copy it try to type the same)
  • Then type adb shell wm density 560 (This is the default setting used in WQHD+)
  • If you are using Powershell instead of command prompt for writing adb commands then don’t forget to add .\ before every command. So for PowerShell use the below ones.
    • .\adb devices
      .\adb shell wm size 1439×3199
      .\adb shell wm density 560
  • Go into developer options and set the minimum width to 411
    This is a default setting when you choose wqhd+
  • That’s it your phone is now running on WQHD+ resolution with 120Hz.


Finally, a way to use it people have been waiting for ti for so long. Expect a slight effect on battery life, but on the other hand, you will be able to see crisper and clearer images and texts while using the phone. The heating will be there initially for 5-10 minutes after which it will settle and work fine. You can also use Bixby routines, as usual, to switch between 60 and 120hz but your QHD will be constant. So you can decide which side you wanna be. Feel free to connect to us on telegram, we have a group of people using Galaxy S20 and will be more than welcome to help you.
