dell U2518D flashing monitor

I just bought a new dell U2518D monitor and when I connect it to my MacBook Pro (15-inch 2017 - macOS High Sierra version 10.13.6) through the HDMI port with an adaptor piece for the USBc connection on the side of my MacBook, the external monitor flikkers every few seconds. Is there a way to fix this?

Using Samsung S27A80 external monitor(s) with 2019 MacBook Pro I have two Samsung S27A80*U monitors. I have attached them to my 2019 16" MacBook Pro using USB-C 3.1 cables. When I have two monitors attached, the MacBook frequently freezes, flashes vertical lines on the main monitor, then crashes back to the login screen. If I detach one monitor, then it stops crashing, but frequently freezes. It becomes pretty much unusable. Once I have all external monitors detached, the computer behaves normally. Has anyone else had experience with this issue? Is there something I'm doing wrong? Should I upgrade the cables (these are the USB-C cables that came with the monitors)? Am I SOL with these particular monitors? They're listed as Mac compatible. Thanks.

2017 Macbook - Not able to connect to 4k monitor via USB C port I'm trying to connect my 2017 MacBook to a Samsung M8 Monitor however the monitor is not able to detect the MacBook via the USB C port input. Since I'm not sure if the issue is with the monitor or the MacBook, I did the following steps to make sure the monitor was functional. The USB C port on the M8 Monitor is able to detect and charge my dell latitude laptop and Samsung galaxy tab s7+ without any issues. I tried using a different USB C cable but still can't connect to the MacBook. The other peripherals connect fine with the different USB C cable. The MacBook is able to connect to the monitor via HDMI input. I used a USB C hub for the MacBook and connected the HDMI to the USB C hub. Ideally, I would prefer using the USB C cable for a cleaner setup. I noticed a weird behavior when I power down the MacBook completely, connect the monitor's USB C cable and turn on the MacBook, the MacBook will charge but still not display on the monitor. However when I disconnect and reconnect the USB C cable while the MacBook is turned on, the MacBook does not charge or connect to the monitor. I tired to reset the MacBook PRAM and SMC but it didn't help. The MacBook is currently running the latest Ventura OS.

Ultrawide 49" Display <> Macbook Air 2018 in Ventura 13.1 issues Hello, Today I decided to update to macOS Ventura, since doing so I have been experiencing display issues with an external monitor. I believe this is an Apple side issue with macOS Ventura. I have done some research and stumbled upon a few other Apple users having similar issues. On reddit, on /r/ultrawidemasterrace The graphical issue is identical to what I am experiencing (it looks different because my wallpaper is different). I am using a MacBook Air, Retina, 13-inch, 2018 with a 1.6 ghz Dual-Core Intel Core i5 Up to this point, I was having no issue on Monterey or Catalina with running this display. This happened immediately after installing the Ventura software update. For context, I am using a caldigit element hub 4 as my central docking station. I have tried both the hdmi and displayport inputs into this monitor, I normally use dp. I use a dp to lightning converter since the element hub 4 doesn't have DP or HDMI ports, only USB-A and USB-C ports. I have tried connecting the monitor directly to the air, and using the other port for power, this did not help. Users on MacRumor's forum are reporting similar issues since October. Ventura external display problem Temporary fix for external monitor issue over usb-c in Ventura So far, the workarounds seem to be Revert back to previous operating systems Run a process in terminal every single time sudo sleep 20 ; sudo kill -9 $(pgrep WindowServer) Run the monitor in PIP mode (only using half the resolution) Potentially booting from Safe mode Please have one of your Software Engineers address what is causing this bug. My theory is this appears to be tied to the resolution or refresh rate exceeding the graphical capabilities of the macbooks, but this is happening across different models. All of the previous hardware and displays has worked, so it cannot be a hardware issue. I do like the new operating system, and would not want to revert to an older version simply to get my display working again. I have attempted to go into the Displays setting and adjusting the resolution, but I mistakenly selected the "use as main display" dropdown (when using my laptop to adjust settings) and now cannot navigate/access to undo this mistake as it has to be in that mode to see that setting again. Other settings do not allow you to adjust display preferences - another potential fix in the future. I hope apple can roll out a fix quickly, because this is debilitating. Thank you,
