Ventura display corruption on 5120x1440 resolution

I use a Philips PHL 499P9 ( 5120x1440 ) connected to a Macbook pro 2018 13" I5 2,3ghz running Ventura 13.0.1 using USB-C (Apple Thunderbolt cable). Screen scrambles. It was previously working fine on both Monterey and Big Sur!


Is there any fix schedule?? Do I have to downgrade to Monterey?

Hi Claire,


I use a (Apple) Thunderbolt (Usb-C type) to connect my PHL 499P9 directly. I also have a Windows Laptop, still working fine with my PHL 499P9 at 5120x1440 in 60Hz. If I connect my Macbook Pro to my external monitor and choose 5120x1440 (which is nativ resolution for this monitor) my monitor screen is scrambled / unreadable. When I tried different settings, I even ended up with having my laptop monitor being scrambled and my monitor working in low resolution...?... weird. My workaround just now is to use 3840x1080 resolution and a HDMI cable with a HDMI to USB-C converter connected to my Macbook Pro, but I have to use the USB-C port on right side to make it work (I normally use a port on the left side for my Thunderbolt-cable). If I use a port on the left side, it flickers to this scramble view a bit.


To me, it looks like there is serious driver issues with Ventura....


I would be thankful if you can help!


Cheers //Jan

Hi did this ever get solved? I have the exact same issue with the same Philips monitor and a 2017 MacBook Pro. Monterey was fine and still is on my other Macs. Boots fine in safe mode. Then is no good when normal boot - scrambled colours / flickers in both laptop and monitor. No login items in the login list. Did a full clean reinstall of Ventura 13.1. Basically makes my monitor unusable. Super frustrated!
