Acer Predator XB273K GP Monitor Flashing Issue in HDR & High Brightness Modes

Hi all,

I have been experiencing a black screen flashing issue with my Acer Predator XB273K GP 27" 4K monitor. It started a few weeks ago when it would have black flashes when I first started my PC, however, it will only last for a few minutes and then stop flashing. Over time, the flashes started lasting longer before going away, and today, it did not stop at all (it has been more than 2 hours).

What I’ve Tried:

  • Tested multiple cables (DisplayPort & HDMI)
  • Updated all drivers and software
  • Factory reset the monitor & checked for firmware updates
  • Tested with and without G-Sync, refresh rates and HDR
  • Verified issue persists even with no input (No Signal Screen)

What I Have Found:

The only way I could stop the flashing was by switching the monitor from HDR Mode to Eco Mode. All other modes, such as Action, Racing, and Graphics, also exhibited the same flashing issue. I tried to understand the difference between Eco Mode and the other modes and discovered that brightness was the cause of the problem. Even when I stay in Eco Mode, increasing the brightness from 44 to 100 causes the flashing to resume. I've noticed that the higher the brightness, the faster the flashing occurs, while lower brightness levels result in longer intervals between flashes.

I’ve recorded the issue in HDR mode, Eco Mode, and with brightness adjustments.

Does anyone know what might cause this? Is it a hardware issue, or are there fixes I haven’t tried? Any help is much appreciated!

    Try disabling adaptive brightness option if available on your GPU's control panel.

    The Flickering: Seems to have been caused by a mixture of HDR, and G-Sync. turn off HDR, set the monitor and my Nvidia drivers to fixed refresh rate, and check if it stopped flickering entirely.

    Thank you for your recommended fix. Unfortunately, it seems my PC does not have adaptive brightness. I have looked everywhere, including Windows Settings, Nvidia Control Panel, and Acer Display Widget, and there are only manual brightness settings.

    Thank you, Axxo, for your insight and recommended fix. Unfortunately, I have disabled HDR and G-Sync and tested a few fixed refresh rates (120, 60, 30), with all having the same result once I set the brightness higher than 70. The screen does not flash under a certain brightness level, and when I want to use HDR, it puts the brightness above 70, and that is when flashing starts, regardless of G-Sync or refresh rates. Even if I have HDR and G-Sync off with a fixed refresh rate, anything above 70 brightness will start flashing. Weirdly, the brighter I set it, the faster the flashes are.

    Go to Settings. Click System. In left pane click Display. Post screen shot(s) of right pane if possible.

    Hi JackE, thank you for being willing to double-check. Here are two screenshots of the Display Settings.

    Just as an extra add-on, I have also seen people Enable/Disable Adaptive Brightness under their Advanced Power Settings, but I do not have that option.

    Does this include the proprietary XB273KGP driver and widget from the Acer downloads? The latest is for Win10 & earlier versions. Should work on Win11

    Yes, I have downloaded the latest drivers from the same page you shared. I have also updated the Acer Display Widget to the newest version (SW Version 4.0.2.0). I have tested the monitor on other devices, such as my MSI laptop, which does not have the drivers or the widget installed, just to see if the issue is with my PC or the monitor itself. I have also tested it with another power supply, as my friend has the exact same monitor; unfortunately, the problem persists.

    I am starting to think that something in the monitor itself has broken and can't handle it when the screen brightness is higher than 70. As per usual, something like this would happen after the warranty has already expired.

    That was the answer to my next question. Sorry, I mistakenly assumed it was a more recent purchase. From your descriptions, my best guess is the screen's inverter board connections between the mainboard & screen. It controls the LED backlight.

    Could be as simple as re-seating the connectors a few times to help clean the connector contacts. Or the board itself. Cost about $90 new. However, disassembly in either case is a challenge with a fair risk of collateral damage.

    I bought the monitor in September 2021, so it is only 3 years and 3 months old. And being a more expensive, higher-quality monitor, you would expect it to last much longer before anything starts to break or give in due to usage. I will find out if there is an official Acer repair centre or partner in New Zealand that specialises in this, as I don't want to have it disassembled by a random business, and as you mentioned, get collateral damage. But thank you for your time and suggestions, I appreciate the assistance.

    Not me. Screen-related parts are often the same or similar to those in cheaper models. QC/QA is about the same. And simple environment conditions like high humidities often cause connector contact issues. So if it was mine, I'd probably try to find a partner that also services other brands. Otherwise, repair costs might be about the same as an officially re-furbished or re-certified unit.
