LR4 hangs when I try to use dual monitors.
I had no problem with LR3.

I use dual monitors, and upgraded my windows 7 (x64) from LR 3.6 to 4 yesterday and so far haven't seen any issues with the use of the dual displays. Can you expand on your problem possibly?

Windows 7 Home Premium (64 bit)
AMD Athlon II Processor 3.01GHz
4GB Memory
GeForce 8400 GS Graphics Card (latest driver installed)

If I try and use dual monitors in develop mode LR4 hangs and I keep getting a black band across the top of each screen and (not responding) message in the tool bar.

I'm experiencing a slight delay when using dual monitors. I understand that the graphics processing takes time, but my second monitor refreshes before my first. Since I only occasionally glance over to the second monitor, if LR refreshed my primary monitor first instead, the delay would be much less noticeable.

Also, since the second monitor drastically decreases response time, it would be nice if when scanning through photos quickly, it would wait until I was done browsing before updating the second screen instead of having it slow down every time I change images.

My main concern with both of these is that I think the secondary monitor should be just that, secondary, and given less processor priority than the primary monitor. I think it might help to approach it like the software handles high-quality previews and waits to load them until after the after the computer has had a chance to respond in a speedy way.

I agree with Jason. If anything must be sacrificed to fix this bug, let it be the speed of updating the second monitor.

However, LR3 didn't have this issue, so it must be possible to fix this defect so that both monitors perform quickly.

I have the exact same issue as Steve, same symptoms (to be more precise : LR stops responding for 5 seconds, then resumes for 5s, then hangs, then responds, and so and so forth). I have to turn off the secondary display in LR4 for it to start responding again. If I activate it again, the problem reappears after a few minutes.

I primarily work with Lightroom 4 and dual monitors on a Mac and have not seen this behavior. But a couple people here have mentioned Windows 7. Is everyone who is experiencing this in Win7?

This problem was cured for me with release 4.1.

Unfortunately 4.1RC introduced a hideous blurring in the develop module whenever a parameter was changed. Unusable!

I've stuck with 4.0 and just don't use the 2nd monitor view now :(

Release 4.1 seems to have solved the problem.

I use DisplayLink software to use my iPad as a second monitor.
After some time while using Lightroom 4.0 there is monitor plug in and plug out issue appears until I turn off thr iPad programm.
So there is no way to use it.

With 4.2RC, LR seems to be twice slower on dual screen than with only one screen. It seems to render twice the image, one for each screen. The second screen in loupe mode is updated before the main one in develop module.

With the first develop raw (let's say five or six), lr is always much faster. With time lr become slower slower and be unusable. Closing the second screen stop the problem. This is the same behavior than here http://feedback.photoshop.com/photosh...
