I know some screens allow you to have multiple 'displays' within the single screen. Out of interest, is there any software that allows screens without this feature built in to achieve the same thing?

You want to display outputs from 2 machines on the same screen, but the screen doesn't allow picture in picture?

The only way I can think of achieving that would be to use software like Anydesk to window one machine onto the other

If 1080p is acceptable, there are quite cheap PIP boxes for 4 HDMI sources that have side by side as one of the options. Its made for video so it scales, not sure how they would feel about 960x1080 as an input resolution. I have one to keep an eye on 3 different DVRs and youtube on the garage and shed TVs.

https://www.aliexpress.com/item/33012999217.html is the one I got. It works ok, but as its just forcing inputs into a 60Hz output its not nice for 50Hz content. Also a little lag makes using a mouse feel like using an office PC.

I was wondering if you could split you screen into two displays i.e two desktops. But I guess you need two inputs. Do the screens which have multiple displays have multiple inputs?

I wasn't sure if you could send two outputs via a single HDMI cable..

Seems obvious now I say it.

believe it will come down to the display. Not any device into them (unless the signal is pre-edited in say a HDMI muxer before display)

IE my Dell screen I am on now. Has DP, HDMI, S-video, DVI x2, Component and S-Video in. But can only do PiP (picture in picture - but that is only windowed or 1/4 window size side-by-side) with the last 2. Split digital is not possible.

LG however, focus on it as a sell point on larger monitors.

Ummmm... why not use windows? If you have two Windows machines, you can RDP (mstsc.exe) from one to the other, and have the second system's desktop in a window on your local machine's desktop. I don't know if there's a way to resize the local machine's desktop to only use half of the screen, but you can position local machine windows to only be on half of the screen. But if you have a 3rd machine, RDP from that to the other 2, with each desktop resized to half the screen.

Unix/Linux allows you to display windows generated by one machine on the desktop of another. I think Windows 10 (or maybe 11?) has something similar?

Are you after 2 desktops on the one computer (ie like 2 screens on the one computer) or is each screen from a different computer?

The rest of us just snap a window to a side of the screen. I guess we’d need to know what you’re trying to achieve.

I assume you are using windows and just want to split a screen into two, you can try PowerToy's FancyZone
https://docs.microsoft.com/en-us/windows/powertoys/fancyzones

It gives a little more flexibility for sizes than the default snapping of windows to the edges.
