Getting intermittent black screens whilst using Freesync on this monitor. Have tried changing PSU, GPU etc but no luck resolving. I have searched across other platforms and the vast majority of owners are experiencing this exact problem with this unit, making freesync unusable. I'm hoping this might help raise awareness to Acer but also enquire with you if anyone has managed to resolve this issue, besides simply switching Freesync off. Thanks.

    have you tried to update the monitor drivers manually. First download the monitor drivers from acer website and then extract the file, save it on desktop. Go to device manager and right click on monitor drivers and update it manually.

    Hi, the KG271UA isn't listed in the drivers list. The KG271U is however, and these are the drivers I'm currently using. The former is a 144hz, the latter is only 75hz so it could be a driver problem but not one I know how to fix unfortunately!

    I see there are drivers available in this link : https://www.acer.com/ac/en/US/content/support-product/7370?b=1 However, the most updated drivers are for Windows 8. Be informed Windows 8 drivers are still compatible with the device.

    Thanks Rudy but that link looks like the same KG271U drivers I'm using.

    In around two weeks of use, I have not seen this issue once since turning off freesync. I have spoken to other owners who have said it affects Xbox One X freesync use, as well as G-Sync use on an Nvidia card (I am using AMD so running true freesync).

    this is what i found in AMD community. Might worth a try.

    Changing the display color depth to 6 bpc (from 8) in Radeon Additional Settings has resolved the issue completely with Display Port 1.2/Freesync enabled.

    Hi Rudy, I have previously tried that but it didn't help I'm afraid.

    If this does not help then i'm sorry that i really couldnt find any other solution.

    Rudy, what would happen if I tried using a more up to date driver from a different model? The XF270 has similar specs and a much more recent driver. Is this worth a try or could it cause damage?

    It wouldn't cause damage but yes as you mentioned its worth a try. Post updating the drivers if the issue still persist then you can uninstall updated drivers and re-install the one for this device from acer.com

    Sorry Rudy but no luck with other drivers. Also turning colour depth to 6 bpc doesn't work either.

  • Hello! For freensync to work, you must have a processor, a video card, a dp cable and a monitor compatible with this technology! What is the model of your computer and your video card? What is the version of windows 10 and have you updated the drivers?

    Hi,

    CPU: Ryzen 1700
    16gb DDR4 Ram
    GPU: RX Vega 64
    PSU: 850W EVGA Gold
    Motherboard: AS Rock AB350m Pro4
    Monitor: Acer KG271UA. 
    OS: Windows 10 Home Edition Version 1803. 

    I am using the supplied 1.2 dp cable. I have also tried to use with a different graphics card and a different PSU. 

    To clarify, Freesync turns on fine and I have smooth frame rates but get black screens every few minutes when it is enabled. I believe this may be a firmware/driver issue as I can see on Reddit etc other people are having the same problem. 

    Thanks.



  • Have you tried lowering the refresh rate to see if the problem remains?

    I have tried capping my frames per second in-game to 120 instead of 144 but this didn't help. I will try to change refresh rate this evening to see if that helps, but that is not a long term solution, especially as the high refresh rate is the main reason people purchase this monitor. 
    Thanks. 
  • I know that! You can change the resolution also in windows:

    This will only serve as a test!

    Hi, yes I have updated video card drivers and also tried a couple of older ones too. On 120hz and 100hz this issue is still very present. I did not notice it on 60hz but I only tested each refresh rate for ten minutes or so. Thanks.
