When are they going to return the ability to enable a window to span multiple displays. Miss that feature.
Got a tip for us?

Sidecar: Turn an iPad Into a Secondary Mac Display

Would be cool if Apple released a 16:9 iPad sized display just for this reason. I love their displays, was looking at getting a 2nd monitor, this seems like a decent way of doing it tho I don't need all the features of the iPad just the standard display size for movies, monitoring in FCPX, and screen recording at 16:9 for editing later.
Funny, but the only time I used that feature was when I needed to check the alignment of one display to another in Display Preferences, or when I wanted to check color temp or brightness across displays... I do miss it when I need to do those things.
1. Go to system preferences -> mission control
2. deactivate "displays have separate spaces"
as a trade off, you will lose full screen windows
[doublepost=1561692452][/doublepost]i wonder if sidecar works as a third or fourth monitor
i don't have a compatible Mac to check this by myself
Edit:
I've found the terminal command, to activate sidecar on unsupported Macs.
Despite the terrible display quality, it works great even as a 3rd monitor. Haven't tested it as a fourth monitor yet. Will check this at work, when Catalina will be published this fall.

You can do this today with Astropad. Works pretty well.
I'd love it if Sidecar worked with a second MacBook as another option. I'd use it all the time between personal and work devices.
Yeah on mine it doesn’t do the iPad as a second display. It only mirrors. Not sure why. I’ve restarted and changed settings and nothing fixes it.
I have! It works very well. There are some two finger scrolling bugs with Photoshop when you try to pan around the canvas though. It’ll just act as though it’s hyper sensitive and jump around. I stupidly broke my Intuos tablet by installing Catalina, but this is a great replacement. The pencil works marvelously wired and wireless. It does take some getting used to with the lack of key commands. I’ll mostly use it for in-depth tasks like heavy dodging and burning or refining selections. It is quite wonderful being able to sit on the couch with the iPad and go about your work.
Lightroom I haven’t been as happy with, but that’s mostly on Apple. When sorting large numbers of photos, I found the X keystroke doesn’t work in sidecar. There’s also a lack of arrow keys. So if you use Lightroom for editing, it’d be great for that. If you’re trying to sort through wedding photos you shot, not so much.

Latency is my biggest concern. I write music to picture, and would love to use an iPad to display the movie while working on Logic on a MacBook Pro. Mobile setup.
Wouldn’t work so well if the latency of sidecart makes the movie display discernibly later on the iPad than it is on the Logic’s timeline. The sync would throw me. That said, logic does have preferences to adjust for display latency, but sidecart latency would need to be consistent for this to be acceptable.
Anyone have any experience with latency?

how does it task the CPU?
I used DUET and it really turned my macbook hot. Also I can't believe my 2015 MBP is already outdated. I am still on 120+ battery charges, still 5000+ to go.

QUESTION
What EXACTLY is the measurable latency showing up in tests—BOTH wireless and wired?
The Apple Pencil still has no hover, so no lasso work etc. in photoshop. 
Ah yes you can't start it from the Mac. Just start it once from Mac, minimize on iPad and use when you need? How is this an issue?
for an extra 1500 € I can finally get some touchscreen functionality for my 2800 € MacBook Pro!
Touch gestures are not supported in Sidecar. In some apps, you can scroll with two fingers, but that's about it. Watch the video.
I bought the Luna for this purpose and it failed very badly. 30fps at 1/4 resolution and filled with compression artifacts. If that's the best a hardware dongle can achieve, I don't have high hopes for this Airplay extension. I hope I'm wrong.
So you want a 16:9 display, with none of the ipad features... why not just get a 16:9 monitor then?
Can anyone confirm if it's going to work with iMac Late 2012 model, I mean I can airplay from iMac to apple tv so why it would be shunted for iPad? (mine is iPad 6th gen)
What are the options for the iPad screen resolution? Can you adjust them in the system preferences of your Mac?
Makes a bit of sense though. The Mac has to do the hard part aka the HEVC (H265) encoding. Apple has set the standard pretty high. The latency needs to be super low and the quality still needs to be decent. This puts a lot of pressure on the encoding part.
Seems they went with solving this by encoding in dedicated silicon either through Intel (if the Mac has a QuickSync-capable Intel CPU) or through AMD. However the GPU in Mac Pro is simply too old to support HEVC encoding.
The override terminal command lowers the standard to allow H264 hardware encoding and then all of a sudden a lot more macs are capable. The resulting image can look pretty darn crappy though, as quality is sacrificed heavily in favour of latency.
Catalina and iPadOS have not been released yet, they are only in beta. Compatibility might change, so it seems reasonable to not list them yet. I would call it a blunder if they are not listed at release, but that hasn't happened yet, and I don't think it will.
I wasn't expecting my Late 2105 iMac to be compatible, and am happy it is, but I won't rely on that until release.
It is a pity my old iPad 4 is not compatible. It isn't doing much, so could have been a permanent third screen. But that might be a future use for my iPad Pro 12.9.

This would be great. When I upgrade my iMac, it would mean I could use the old one as a second display. Apple would benefit from added utility for old machines (increasing the value of the investment in buying a Mac), while not damaging the demand for new ones (maybe even increasing it). Even better would be if it could use the power of both machines, but that is being extremely optimistic.
I’m fine with using the pencil for cursor operations like selections and tapping ui, but I wish sidecar was a little more generous with using the iPad interface for trackpad gestures like scrolling and zooming.
It seems to be supported in some apps but not others, and I’m not sure why it would need to be implemented on an app-by-app basis rather than just emulate trackpad input for two finger scrolling and pinch to zoom.
