Retina support between two M1 Macs

I'm using Jump Desktop on a MacBook Air M2 (8.9.10) to connect using Fluid to a MacStudio (6.8.91) and can't for the life of me figure out how to enable custom resolution or ideally Retina displays.

This is my JD client setting, just to test a higher resolution, however as you can see no matter what settings I use, it doesn't change the resolution of the connection.

Thanks for any suggestions.

  Hi Steve,   I'm new to JD and have a setup very similar to what you are trying.  I'm connecting a MB Air M1 to a MB Pro with same versions software of JD and JD Connect.  My host machine (MB Air M1) runs close to 4K resolution (3008 x 1692) and I have the MB Pro running at 3048 x 1905.   Under the "Display > Resolution" setting I usually select: "Same as Remote Computer w/ Retina" and it works fine showing my entire MB Pro desktop in the full 3048x1905 in Windowed mode.  I tested changing the Custom resolution settings and it appeared to work fine.. I tried a lower resolution like 2880 x 1800.  It does not look very sharp bc of the lower resolution (even though Retina mode).  Maybe you could try it in "Windowed Mode" vs "Full Screen" to see if that makes a difference?

  Also, are you connecting locally (same LAN) for this connection or is one of the machines at a different location using the Internet?   I'm just trying to connect from one MB to the other in the SAME LAN, but I feel like the JD App is trying to go out to the Cloud to connect between the two machines.  It's very strange how you can't create a "Fluid Desktop" connection manually, it just gives you option for: VNC or RDP.   I've tried asking Support about this but have not received an answer yet.

  Thanks for the reply and insights @Erin Smith, greatly appreciated.

  This gives me hope that everything should work, just need to figure out the magic combination I guess.

  I'm starting to think that because my MacStudio that I remote into is plugged into a HD TV (it's my main server machine now), the fact the HDMI is connected is possibly restricting the overall resolution.  I'll play around with that.
  
  A few more points of clarification, and I'll head over to support to see what else might be suggested:

  Connection type = Lan to Lan (same subnet)

  Tested Displays in = Both Single and Separate Windows

  Start in = All three options, Windowed, Full screen on current and also Full screen on all displays

  Resolution = Have tried them all, including custom resolutions just to see if the resolution changes, in my case it is stuck firm to 1920x1080.

  The awesome support team got back to me quickly with a fix, simply change the virtual display to 1 and it works, both custom resolutions and retina support.
