Does SU work with dual Monitors?

I did a search here about dual monitors and found some old posts and some that really didn’t help me. Wondering how SU works with dual monitors? I have a 22inch Monitor and my default tray and add-on menus are taking up real estate that I want for working. Is going dual better? Does it work? Or just get a bigger monitor? Appreciate input.

I use two monitors all the time. If you leave the trays open when you quit SU, turn the other monitor on prior to opening SU for your next session.

I’m just trying to figure out how that looks or works. So you what? On very first start up you drag your menus to the other monitor and have the main monitor as the model area only? Thanks in advance.

You have the right idea, drag them over or drag the main window over if you wish

. The screenshot is the arrangement I usually work with. Also I will put toolbars from extensions on the second monitor as I use them.

Dual monitors should work fine, but be aware that for best results they should have the same resolution and once you start using dual monitors you should always have both of them attached and live. There are occasional reports here of SketchUp losing track of where to place its UI panels (that is, opening them off-screen) when you switch from dual back to single for any reason.


Thanks a lot. I was hoping for a screen shot to show me what it looked like.

I run SU on Mac with two monitors of very different resolution - an iMac 5K 27" screen for the main working window, and a much smaller portrait orientation 17" (diagonal) monitor, running at 1024x1280 which sits to the right of the main iMac screen, and is very closely matched in vertical screen height - both are very close to 13" high - though a much coarser resolution.

The second monitor is plugged in to the mini-displayport/Thunderbolt socket on the rear of the iMac, with an inexpensive non-Apple converter to DVI to plug into the monitor.

As Steve says, you can run into trouble if you forget to switch on the second monitor before starting SU, but that has only very rarely happened to me.

Thanks John. I don’t have a Mac but your setup is closer to what I envisioned using.

I used to do the same with a Windows 7 machine, a Full HD 24" main monitor (1920x1280 IIRC) and the same 17" monitor in portrait.

One connected via HDMI, the other via DVI. The HDMI connection to the main monitor wouldn’t auto-powersave to black, but would show a bright blue screen until manually switched off.

I use a second monitor, actually as the primary one, on my MacBook Pro while on my desk, and only the laptop display on the road. I keep two sets of preference/jason files to swap in an out, which is a real pain. That’s the kind of process that computers are good at performing, but now one’s put their mind to it. Someone did years ago for PowerCADD with a simple little utility, but almost every MacOS upgrade broke it and he got tired of fixing it.

I haven’t yet tried the trick of creating another user account for the road. You’d have to set things up with file permissions so that both accounts can work on the same file sets, and the installation of plugins to be global (all users), not just in one user’s account.

I have three!

I use it with 3 monitors:

  • laptop (15" HD)
  • 32" 4k
  • 24" HD (vertical)

Depends on how you want to work. Moving toolbars to other monitors is fine, if you work with one instance of SU. If you are sing several instances of SU - this will become confusing.

Note, if you change configuration sometimes (e.g. I have different arrangements of monitors at home, but also extra 2 external) - Alt+Space is your friend :smile: (if something opens off-screen).

those are rather TV’s, than monitors :slight_smile:

Not much of a difference these days other than refresh rate which you don’t need more than 60hz for most applications. Now gaming that’s a different story!
