Haiku have added support for multiple monitors ?.
I have been waiting for this is 2020 so maybe ?.
:D.
With additional hardware for a long time …
There is some limited support with some old video cards (Radeon 7000 and 9250 from the early 2000s for example). New drivers have not been adjusted to handle it yet. I may have some time to work on it for the Intel driver. It’s been a bit more complicated for me lately due to working from home and that means having extra laptop from work on my desk, so no space for a second Haiku device to test drivers on.

Notice that, as shown in this screenshot, Polli’s approach results in the operating system having no idea there are multiple monitors, and so it cannot make any decisions based on their position and size.
It’s been too long so I can’t comment anymore. There are also advantages when the operating system doesn’t know everything …
From the user’s point of view, mind you!
I find exlusive aplication for linux, and i thoght maybe port that on haiku
@pvalue This is a utility to provide a user interface to configure existing multi-monitor functionality for a very specific environment. This doesn’t help at all in making a system support multiple monitor.
If Haiku itself fully supports multiple monitors adding a settings app for this is likely the least concern.

There are DP to 2*HDMI adapter that present 2HDMI monitors as one wide DP monitor, works well with haiku

The Screen preferences actually already has the needed code in place! But it only works with early Radeon cards (7000 to 9250 range) and maybe some Matrox (G200, G400) cards. So if you own hardware from after the 2000s, that is of no use to you.
It would be great to see more drivers making use of that feature (even if the way it is done is not the cleanest, it would at least give us a starting point).

Over on Genode - land, Sculpt now has a very full multi monitor support. I wonder if it is possible to borrow from that project to get something better?
Multi monitor also works with the native screen app for all supported old nvidia cards btw. So GeForce 2 UpTo/including 7950.
