And even when it does, it fails to wake up from sleep mode.Īnd going by the vast majority of reports, the issue does seem limited to the previous year’s MacBook Pro 16” 2019. Others have lamented that their PC can’t detect the monitor at all. The refresh rate also takes a significant hit and may max out at just 30 FPS.
#MACBOOK PRO 4K 60HZ DISABLE SIP SWITCHRESX 720P#
Somebody else had a similiar problem?Īs apparent from the above complaints, 4K monitors seem to run at non-optimal resolutions like 1080p or even 720p when connected to devices like the MacBook. I restarted and plug / unplug the monitor already several times but it will not work. But after the latest update to big sur 11.1 its no longer possible to use 4K Resolution… even with SwitchResX the resolution is unavailable. I am connected via USB-C on both ends and the resolution was fine before the update. MacOs updated today (Big Sur 11.1)and I can no longer get the 4K resolution for my external monitor (LG $K HDR 43) which I need. It appears that macOS’ latest update virtually breaks external 4K monitor support, giving users a really hard time. The macOS Big Sur update 11.1 was released on December 14, and right afterward, a slew of complaints emerged on the Apple forums about issues related to 4k monitor support.
