M4 and 3840 x 1620 hidpi resolution on 5K2K ultrawides

[erikjoya]

Hi, It seems my only way to avoid sleep issue with virtual screen and mirroring is through your native/flexible scaling. I tried adding the custom resolution but I'm only given a lodpi option at 3840 x 1620. I'm using a macbook pro m4 pro 14 so technically it should be able to support the 2x scaling.

Am I missing anything? The monitor is a decogear 40 incher ultrawide with a native resolution of 5120 x 2160. The panel is LG based ips.

The problem with the M4/M4 Pro Mac is that for some hard to understand reason it arbitrary limits max horiozontal resolution. Some report success getting 3840px horizontally at 120Hz. Difficult to understand the logic behind it. For more info about this, take a look here:

@erikjoya if you add a virtual display it will work, not ideal but the only work around that I have found.

Is there a delay between user actions and the display feedback when using screen mirroring?

I have only been using it a few days but it seems like at times my pointer will lock up or lag randomly. I also have issues with the screensaver not coming on or media not playing correctly.

There should not be a delay but on Apple Silicon the mouse feels a bit uncertain as @dave-fl mentioned when mirroring a virtual screen.

I’m experiencing the same issues. Random mouse lag. The current workaround to auto disable and enable virtual screen before sleeping is erratic, 50% chance it will get stuck not turning the display offOn Dec 27, 2024, at 6:17 PM, waydabber ***@***.***> wrote: There should not be a delay but on Apple Silicon the mouse feels a bit uncertain as @dave-fl mentioned when mirroring a virtual screen. —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you were mentioned.Message ID: ***@***.***>
