Hi Everyone, I recently did an update to macOS Monterey Version 12.3.1 and now my Dell S3422DWG will not recognize the resolution past 1340 x 1900. It should be able to go up to 3440 X 1440 which it did before the update.
Has anyone else ran into this issue? If so how did you resolve it?
Also, I have tried different HDMI cables, as well I connected the monitor to a Windows 10 machine and no problems recognizing the 3440 X 1440 resolution
I just bought a Dell monitor yesterday and having this issue. I set "Smart HDR" on my Dell to "Off" which opened up the 2560 x 1440 option on my Mac but it's still not using the full width of my monitor. Pretty annoying to the point where I'll probably return the monitor.

Hi all,
I purchased this cable which is a USB C to DisplayPort cable 10 Foot and it resolved the issue

Now I am getting 3440x 1440 which from both monitors.
Test it out and let me know if you experience the same.
I found something in another topic that might be helpful. I can't try it since I don't yet have the monitor.
"Hi same issues here since update to 12.3.1.
2x LG ULTRA WIDE monitors connected to Mac Mini. 1 of them could not get the correct resolution.

Just got off the phone with Apple support and they want me to wipe my system completely clean, then provide them logs of my blank system.
I was hoping someone from the community had this issue and has found a resolution because it appears the last update for MacBook Pro's macOS Monterey version 12.3.1. has effected the video card.
This review got my attention because they have a MacBook Pro 16" 2021 because that is what I have tested on:

This cable does not work at all with the MacBook Pro 16" 2021, tested with multiple monitors. This seems to be an issues for users other than me too. Useless cable, they should stop selling it while this issue exists.
I don't have USB-C or DisplayPort. Seems I'm out of luck?

Maybe this would work? https://www.amazon.com/dp/B08SVYZBRZ?ref_=cm_sw_r_cp_ud_dp_YV1H81PB466RR4WFFASY
It appears Apple didn't add that into the Update Fix description
macOS Monterey 12.4 includes enhancements to Apple Podcasts and bug fixes:
Strikemaster did you try it?
Nope, Apple did not want to acknowledge it is an issue with their last update. They sent me back to Dell and Asus.
Dell has been terrible support. I will never purchase a Dell product again from this experience
Asus the only way to get support is by email and they are just rotating support people. Which they have been asking the same question the last agent had not reading the e-mails.
So no help from the Monitor manufactures.
What are you experiencing Strikemaster ?
I'll probably return this monitor and get a different one unless there's an easy fix.
My Mac only outputs Thunderbolt and HDMI, not worth getting a new computer for this. I have a Dell U3417W FR3PK 34-Inch curved monitor as well and that works great.
You can purchase a high bandwidth USB-C to Displayport cable. Here's an example. There are cheaper ones. https://www.amazon.com/StarTech-com-USB-C-DisplayPort-Adapter-Cable/dp/B07VN6B5GR/ref=psdc_306629011_t1_B01J6DT070?th=1
It appears the first review on the display port cable mentions it did not work
"All Macs and PCs certified for Thunderbolt 3, are also certified to push display signaling (via DisplayPort) over USB-C. Unfortunately this cable did not work with recent generation MacBook Pro and recent generation Dell display, but of which are certified for DisplayPort 1.4 and USB-C. Could just be a defective cable but rating 3 stars. Will try another brand of same cable spec / connector types, if that also fails will revise this review since that would indicate not something specific to StarTech model. Generally, in the past, I've had good luck with StarTech specialty display cables like this one (i.e. something other than the same connector spec / type on both ends)."
I will run the test for us I just purchased 2x of these cables

I should have it by Monday and I will test and let you know if it works on my MacBook Pro 16" with both the Dell and Asus monitor.
I received the monitor and the USB-C to DisplayPort cable this morning. Attaching the monitor via DisplayPort to my 2019 16" MacBook Pro worked immediately. The monitor came up in 3440x1440 and I was able to set it to 144 Hz in the Mac's display settings.
So far I'm quite happy with the monitor. I haven't detected and dead pixels, colors and black levels look good. I am wondering a though how well I'll manage with picture-by-picture once I have an opportunity to test it.
Has any of the community experienced this issue
As I felt, it did not resolve the issue see below:
