tuananh19.01 Posted May 31, 2021 Share Posted May 31, 2021 My Mojave system uses i5-4670. motherboard z87p-d3. With full DSDT patch. I use the built-in HDMI port main. The monitor I use is 2k resolution. - My screen flickers. Maybe after 40-60 there will be 1 blink. - I changed the screen to 1080p and this phenomenon disappeared. - Is there any method for me to fix with 2k screen? Thanks Quote Link to comment Share on other sites More sharing options...
