Samsung ultrawide: screen won't fill for Macbook pro

I purchased a Samsung ultrawide monitor (LC34H890WGNXGO), I have it

connected to my 2019 Macbook pro, but it won't completely fill the

screen. I've tried both an HDMI-USBC cable and a DP-USBC cable. There's

still about half an inch around the sides. How can I fix this? I just

want to get the most out of my monitor.

MacBook Pro 13″, macOS 10.12

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.

Resolution scaling option for external display disappeared with update Hi, I have always been using my external 4K Dell monitor with my M2 Macbook Air. Before the update to Ventura, I could scale the appearance on the screen since everything is tiny on a 24" 4K monitor, but since the update the option for scaling has disappeared and the only way to change the size of the UI is to change the resolution, which renders the image unsharp. Any workarounds or solutions? Thanks. Jonatan

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,

Hey there, paeka!

Thanks for using Apple Support Communities! We understand you're trying to get your external monitor to fill the screen when used with your Mac. We want to help!

Have you tried changing the resolution preferences on your Mac? If not, we recommend using the steps under "Change your display resolution" in the following support article:

Get help with video issues on external displays connected to your Mac - Apple Support

"If you can't change the resolution of your display because you can't see an image, restart your Mac in safe mode to reset the display resolution to defaults.

If starting in safe mode doesn't resolve the issue, reset your Mac's NVRAM and SMC to reset the video ports on your Mac to their defaults."

All the best.
