The file SwitchResX generates lives at /Library/Contents/Overrides/DisplayVendorID-90ac/DisplayProductID-40b6, so it's applied to all users, works on the login screen/etc.UHD resolution (also known as 4K) monitors are becoming more and more affordable these days. I'm guessing I could figure out why this was and fix it with SwitchResX, but I haven't messed with it. This does not happen when I run it in clamshell mode. One odd thing I noticed was when I open the M1 MacBook Air for some reason, I lose the 2x scaled mode. After generating the plist file with SwitchResX, I was able to uninstall SwitchResX and just leave the plist file it generated there and everything worked the same. If you want the other scaled resolutions, you might have to fiddle with SwitchResX some more. #Using switchresx driverI've been running it as my daily driver for a month or so. It seems to be working well with 5k resolution at 60Hz. I believe I just enabled the default and scaled resolutions for the monitor which enables clamshell mode. I ended up just using SwitchResX in demo mode to generate one that worked for my needs. Good news: I spent a lot of time on the phone with Apple support gathering info and with them trying to troubleshoot and at the end of the day, their workaround ended up being to be exactly what SwitchResX was doing: Generate a display overrides file to fix things. I was hoping Apple would add in support for this monitor but hasn't. Good news and bad news, but mostly good news:īad news: macOS 11.1 didn't seem to fix things by itself. This monitor has always been a unique snowflake. Unfortunately, things are not "just working", but I have gotten them to work for now. The Apple Support specialist I have been speaking with is supposed to call me back Tuesday with a workaround that won't require SwitchResX that should enable all of the same things hopefully. I downloaded SwitchResX and got that working after much tweaking and can now use clamshell mode. I really wanted a "looks like" display of 2560x1440 running at 5120x2880. The only issue is that it was not scaled properly. #Using switchresx fullAt this point, the display was working in 60Hz at full resolution, but I couldn't use clamshell mode. The trick that I didn't realize at first was that even though only 848圆00 resolution was listed by the display under preferences, I could click "Gather Windows" to get the Display window to come onto my MacBook Air display. So I've had multiple calls with Apple and I think I'm pretty close to having my monitor working properly with the dongle I mentioned above. At the time it was released, neither DisplayPort of HDMI support enough bandwidth to drive the display. ![]() It does this using Displayport MST (Multi-Stream Transport) where DisplayPort combines two DisplayPort streams into one to support one 5K 60Hz signal. It is a strange beast that requires two full-size DisplayPort cables to get a 5K 60hz signal. *Why this monitor needs two cables to do 5K and the crazy adapter I linked above: It was one of the first 5K displays available, and was featured in Apple's keynote when they announced support for 5K monitors. Has anyone been able to get this combo to work on their end? Also, the resolution listed in "About This Mac" is not the full resolution - it's 800x400 or something along those lines. The display shows up in "About This Mac" as recognized by macOS, but the monitor does not recognize a signal being sent. Surely, my 5K monitor should work? Unfortunately I haven't had luck yet. I ordered a M1 Apple Silicon MacBook Air recently since it said it support 1 monitor of up to 6K up to 60Hzto my surprise. ![]() Both of these machines also support this laptop with the same adapter just fine. #Using switchresx proIt also works on my wife's 2019 13" MacBook Pro with integrated graphics as well as a 2019 MacBook Air with integrated graphics. I am using it right now on Big Sur 11.0.1 on my 2018 15" MacBook Pro with discrete graphics. In order to hook it up to all of my laptops that support Thunderbolt 3, I have used the following dongle with no issue: - it takes two DisplayPort cables that hook up to the display, and then just one Thunderbolt 3 cable goes into the Mac*(For why see the bottom of the post). I've been using my Dell UP2715K monitor for years across many Apple laptops. ![]()
