I've never heard of secondary monitor delay. I have a dual-monitor setup and never experience anything of the sort. This goes way beyond Lightroom or any Adobe products. Our applications don't care what monitor they are on, that isn't something that is part of an application's programming. Your CPU doesn't care about what monitor an application is running on either. This is pretty much entirely up to the video card. I would definitely recommend getting your video card drivers updated to the latest version from the manufacturer's website. If that doesn't rectify the issue, you may need to invest in a new card.

Jason - I have similar (maybe identical) behavior, I think.

If you want the performance swapped, just swap your monitors - i.e. put Lightroom's primary view on the other monitor. If you don't like the physical logistics of that arrangement, then swap physically as well.

Maybe one day we'll have thumbs and panels on one monitor and full-screen image on the other, in a single module - I can dream, can't I?

Lightroom 4 is slow when the second screen is activated. It works fine with one screen, but slows to a crawl when I press the second monitor button. All aspects are slow (sliders, image loading, painting a local enhancement mask)

This was reported repeatedly during the beta by lots of people, but why does the team not fix it?
