How to fix GIGABYTE M28U and M32U power issues

If you can’t seem to turn on your GIGABYTE M28U 28″ 144Hz 4K FreeSync Compatible Gaming Monitor or GIGABYTE M32U 32″ 144Hz 4K FreeSync Compatible Gaming Monitor, then you can check out this troubleshooting article at Seeking Tech to see what you can do to potentially fix this issue.

1. The first step we recommend taking is to make sure that the power supply is properly connected to both your computer screen as well as the power outlet.

2. You can also try unplugging the power supply from the monitor, waiting a few minutes, and then plugging it back in again.

3. If your monitor is still getting no power, then you may want to consider using a different power outlet as well since the current outlet you are using could be defective.

4. We also recommend checking if there is any damage on the power cable. If you see that it is starting to break apart, then you should consider getting a replacement.

In this case, you should contact the customer service at GIGABYTE to see if you can get a new power cable.

5. Moreover, you can also try pressing other buttons on the screen to see if you can get anything to show up on your M28U or M32U.

6. If you still aren’t getting any power after taking all of the aforementioned steps, then your GIGABYTE M28U 28″ 144Hz 4K FreeSync Compatible Gaming Monitor or GIGABYTE M32U 32″ 144Hz 4K FreeSync Compatible Gaming Monitor may have been damaged in one way or another.

In general, a computer screen can stop working due to the following reasons:

  • Extreme Temperatures – The GIGABYTE M28U and GIGABYTE M32U have a recommended operating temperature range of 0°C to 40°C or 32°F to 104°F. If you try to use these monitors at a colder or hotter range, then you could end up damaging the screens to the point where they can’t be turned on.
  • Liquid Damage – The M28U and M32U do not have an IP rating, which means that they are extremely vulnerable to liquid damage. Water or beverages may have seeped into the internal components of your screen, causing it to short circuit and become inoperable.
  • Extreme Humidity – If you use your M28U or M32U in an extremely humid environment, then the moist air could also end up getting inside your gaming monitor, causing liquid damage as a result.
  • Power Surge – Last but not least, a power surge caused by a power outage or lightning strike could have easily damaged the power supply or any other internal components of the monitor.

If you believe that your GIGABYTE M28U 28″ 144Hz 4K FreeSync Compatible Gaming Monitor or GIGABYTE M32U 32″ 144Hz 4K FreeSync Compatible Gaming Monitor is still under warranty, then we recommend contacting the customer service team at GIGABYTE to see if you can get your screen repaired or replaced. Otherwise, you will most likely need to get a new computer screen.

How to properly clean the GIGABYTE M28U and M32U monitors

If you want to properly clean the GIGABYTE M28U Gaming Monitor or GIGABYTE M32U Gaming Monitor, then you can check out this guide from Seeking Tech to see how you can properly do so.

What cleaning cloth should you use for the GIGABYTE M28U and M32U?

When it comes to cleaning the screen, GIGABYTE recommends using a soft cloth that is lint free. Otherwise, a dirty and/or more abrasive cloth could end up scratching your screen.

If you don’t have any clean soft cloths currently, then we recommend picking up the Magic Fiber Microfiber Cleaning Cloths. If you are interested, you can purchase a pack of these on Amazon with this link. (#CommissionsEarned).

What cleaning solution should you use for the GIGABYTE M28U and M32U?

When it comes to the cleaning solution, GIGABYTE recommends that you avoid using any acidic or abrasive cleaners. Therefore, we suggest that you use either plain water or highly-concentrated isopropyl alcohol.

Isopropyl alcohol dries a lot faster when compared plain water and will also help disinfect your computer screen.

If you are interested in using isopropyl alcohol, then we recommend picking up the MG Chemicals brand. You can find it on Amazon via the following link:

How to clean the GIGABYTE M28U and M32U

Once you have all the necessary cleaning tools, we recommend that you take the following steps in order to properly clean your GIGABYTE M28U Gaming Monitor or GIGABYTE M32U Gaming Monitor:

1. Before doing anything else, make sure you turn off your M28U or M32U.

2. After powering down your computer monitor, unplug the power cable as well as any other cables you have attached to the screen.

3. Next, we recommend that you pour the cleaning solution on the cleaning cloth.

Do not pour or spay the solution directly on your gaming monitor as the excess liquid could end up seeping through inside, causing liquid damage.

You should also make sure that your cleaning cloth doesn’t become too damp. If you think you accidentally put too much of the solution on the cloth, then you can simply squeeze the cloth over a sink to remove the excess liquid.

4. After applying the cleaning solution to the cloth, you can start wiping your M28U or M32U Gaming Monitor.

We recommend wiping the screen gently as any excessive pressure may end up damaging the screen.

You should also wipe your monitor in a circular motion. This is because wiping is straight lines will leave behind streaks and residuals.

5. Once you are done wiping your M28U or M32U, the next step is to simply wait until the monitor dries out in room temperature.

If you are in a hurry, then you can put the gaming monitor next to a fan for better air circulation.

Do not put the screen near any heat source as doing so may end up causing heat damage.

6. After making sure that the GIGABYTE M28U Gaming Monitor or GIGABYTE M32U Gaming Monitor has fully dried up, you should be able to plug it back in and turn it back on.

How to enable GIGABYTE M28U and M32U VRR support for PS5

Variable Refresh Rate support was recently added to the PlayStation 5 and PlayStation 5 Digital Edition. As a result, you will be able to play most games on your Sony gaming console without having to worry about any stuttering or screen tearing due to unstable frame rates.

Both the GIGABYTE M28U Gaming Monitor and GIGABYTE M32U Gaming Monitors have been confirmed to be compatible with the VRR feature of the PS5.

To see how you can enable Variable Refresh Rate, when playing games on your console, for the M28U and M32U, you can take a look at this tutorial at Seeking Tech.

1. Before doing anything else, we recommend that you update your M28U or M32U to the latest firmware. New updates may improve the Variable Refresh Rate support of your gaming monitor.

2. You should also keep your PS5 or PS5 Digital Edition updated to the newest firmware as well.

VRR support for the game console was added in a recent firmware update. Not to mention that subsequent updates may have improved the compatibility and/or performance of this feature on the PlayStation 5 as well.

3. If you haven’t one so already, use a HDMI 2.1 cable to connect your game console to the M28U or M32U monitor.

You can use the HDMI cable that came with your PlayStation 5 or PlayStation 5 Digital Edition box as it should be 2.1.

If you lost your HDMI 2.1 cable, then you can check out this article to see alternatives will work with your console.

4. After properly connecting your PS5 to the computer monitor, turn on both devices.

5. Make sure that the monitor is displaying the input that is connected to your game console.

6. On your PlayStation 5, make sure that you are in the home screen. This is the main system menu where you can open games and media apps.

7. Next, you need to get to the Settings menu from the home screen. You can do so by selecting the gear cog icon, which you can find on the top right side of the screen.

8. Once you are inside the Settings menu, you need to head into Screen and Video.

9. After getting into the Screen and Video sub-menu, the first step you need to take is to select Video Output on the left column.

10. On the right side inside the same Screen and Video sub-menu, you then need to select VRR.

11. In the pop-up menu, make sure that VRR is set to Automatic. This will enable Variable Refresh Rate for games that natively support this feature.

12. Underneath the VRR setting in the Screen and Video sub-menu, you can also turn on the “Apply to Unsupported Games” setting to use Variable Refresh Rate for games that don’t support this feature.

13. To use Variable Refresh Rate for games that have a frame rate that is beyond 60 frames per second (such as Marvel’s Spider-Man: Miles Morales, Marvel’s Spider-Man: Miles Morales and Ratchet and Clank: A Rift Apart), make sure that you have 120 Hz enabled on your PlayStation 5 or PlayStation 5 Digital Edition.
