macOS Ventura: external display resolution issue

I updated to Ventura yesterday (from Big Sur) and now I can only 'upscale' to higher resolutions on my 4K external monitor. I can choose the higher resolutions (e.g. 2560 x 1440) but it looks fuzzy, not sharp. It was working perfectly before I updated. The monitor is a 27" Viewsonic vp2756-4K, which has the following spec: Resolution: 3840 x 2160, Resolution Type: UHD, Refresh Rate (Hz): 60.

I'm connecting to the monitor via HDMI cable run through an Anker 533 USB-C Hub (5-in-1, Slim) which, as I said, was working perfectly until the OS update.

See display options below:

Does anyone have any ideas how to fix this, please?

Thanks 🙂

This is strange, but I toggled around the display settings by setting the external display as the main display, then as a mirrored display and then back to extended display and suddenly a lot more resolution options appeared, some with better sharpness.

There have been several threads with this issue. While we wait for a comprehensive solution, a third party utility like BetterDisplay or SwitchResX can make more resolutions available.

Thanks Luis. That was one of the first things Apple Support had me do. It didn't work for me, but maybe others will find it works for them.

Thanks Luis. I just tried that and, unfortunately, it hasn't resolved the issue.

Thanks - yes; that's what I'm going to try next. Hopefully, a fix can be found. If so I'll share it.

Same issue. So annoying. Working perfectly on Mac OS (PRE VENTURA). Mac OS ventura ruined the party

Did you try BetterDisplay? It is a free utility that is worth a try.

This worked very well! Thanks!

In addition, installed on other Macs for being an awesome utility.

Yup, exactly the same situation here. Extremely frustrating to have paid for a good monitor and it's not being able to be used properly

It's nice that Ventura gives you the option of a ton of resolutions, but the one I was using pre-Ventura is now blurry. I hope a future OS update fixes this.
