Poor support for 4:3 remote screen such as iPad Pro 13"

I'm using an iPad Pro M4 13" to remote into a Mac mini. The screen resolution of this iPad is 2752 x 2064, which is a 4:3 aspect ratio.

The Mac mini supports quite a few screen resolutions with a this ratio, such as 1280 x 960 and 1600 x 1200, but none of them fully fills the remote iPad Pro screen, with at least a 2mm gap on all four edges. To be clear: the remote screens have exactly the right aspect ratio, but they're slightly small.

I've also tried SwitchResX to create custom 4:3 resolutions such as 2752 x 2064, and half that, 1376 x 1032, with the same results.

Other non - 4:3 resolutions such as 1920 x 1080 (16:9) have no trouble in fitting almost exactly to the width of the iPad screen, but of course their height is heavily letterboxed.

Is this a Jump Desktop for iPadOS bug?

    Im experiencing the same exact problem. Do you have a work around by any chance? I would even be fine with it not filling the entire screen as long as it wasn’t soooo blurry and bad quality. No matter what I do, it looks so fuzzy.

    Stumbled into this randomly and thought I'd add... Sounds like Jump will add this natively in some form, but I was able to resolve this issue with BetterDisplay Pro to create virtual 16:12 display with the resolution set to 1920x1440. With high DPI enabled, the desktop stretches the full width of the display and looks great. Note that you should also select in Jump the option to use home indicator area so it doesn't force a slightly letterboxing to leave space for the home indicator bar.

    I second the BetterDisplay Pro for virtual screen 1:1 iPad size. I’d love more support to iPad as a client to MacOS.

    I requested the beta version of Jump Desktop for iOS as suggested above, and I’m currently running it. It does a great job of solving this issue.

    I’m still seeing issues with resolution setting using both Jump Desktop 10.x betas on my iPad Air and MacBook Pro. In particular, text is subsampled making it very difficult to read.

    With a virtual display enabled and “Match iPad” set for the resolution, the info panel shows it being set to 2744 × 1868. That’s not correct - it should be 2360×1640 for this iPad. When I manually set the right resolution in the Mac display preferences, everything looks clear, so I think there’s just some bug in detecting the resolution to set.

    Edit: Actually, 2360x1640 is the non-retina resolution. If I set it to half at 1180x820, I get a reasonable UI size with crystal-clear text.

    Hi. This could be related to display scaling. Is your IPad Air set to More Space in Settings app -> Display?

    Yes, it is, under Display Zoom.

    Jump Desktop 10 Beta 8 (https://changelog.jumpdesktop.com/jump-desktop-10-beta-8-26geOc) appears to have regressed for this.

    Previously, I could at least change the resolution in the Mac’s Display Settings after connecting, and everything would be corrected. Now, changing the resolution in display settings doesn’t do anything unless I disable resolution matching on the iPad client side.
