Hello!
I have MacBook Pro 13" late 2011 model. It is connected to external 27" display with resolution 2560x1440. I can see that performance on the external display is poor. I work mostly in Lightroom and Pro Tools and I can see that scrolling and similar stuff is going pretty hard. Why is that so? Can I do something to improve the performance of external display? Thank you!
MacBook Pro, OS X Mountain Lion (10.8.5)
Hi mp00172,
I'm sorry to hear you are having these issues with your MacBook Pro. If you are having distortion or other issues with your external display, you may find the troubleshooting steps outlined in the following article helpful:

Your Mac should have support the display with this resolution.
Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on an external display, both at millions of colors
but also its important what kind of extarnal display you have. Apple's 27" thunderbolt or another brand.
if i were you i would try with different adapters DVI- VGA. For example Dual-link DVI output using Mini DisplayPort to Dual-Link DVI Adapter supports 30-inch Apple Cinema HD Display
