Macbook pro 4k 60hz disable sip switchresx driver#
Looks like Windows somehow get the full resolution from the display channel or does have a plug & play driver in place - idk. I validated this by installing Windows 10 in BootCamp and I was able to select the full 5120*1440. I also just got my Dell U4919 DW and having the same issues as described here.įirst of all, if you are using the cables provided with the display you should absolutely be able to get the full resolution on supported Mac's (e.g. ge-and-troubleshooting-guide?lang=en#Usi… requirements-and-supported-configuration… Why can't I get full 5k resolution? Is it an issue with the MacBook, the connection, the screen or perhaps an iOS issue?Īdditional links with information on the screen: My MacBook Pro has 4 USB-C ports, I'm using the left ones which operate at full speed (right ones are reduced). "this model supports a maximum resolution up to 4096x2304 at 60 Hz at millions of colors on two external displays or a single external display at a maximum resolution up to 5120x2880 at 60 Hz at over a billion colors via Thunderbolt 3 (USB-C)." I have tried the app SwitchResX to manually set the 5k resolution without luck, only scaled.įrom this link I read about my MacBook before purchasing the screen that: I have just purchased the Dell U4919DW monitor to use with my early 2018 MacBook Pro 13", but unfortunately I cannot choose full resolution 5120x1440 in the settings, max is 3840x1080.
