Okay, I'm a bit puzzled here. I just picked up a 24" Asus PA248Q display. It's a mid-range IPS monitor, 1920 x 1200 and a response time of 6ms. I'm driving this monitor with a 2010 MacBook Pro 2.4GHz Core 2 Duo that has a NVIDIA GeForce 320M video card. When running any online YouTube or embedded video to full screen I get a choppy playback. Not super bad, but noticable that frames are dropped. Movies played back from my hard drive seem to be okay. Conversely, my older 7 year old 2.0gHz iMac Core Duo with an ATI plays the same online video back perfectly. But it's only driving 1680 x 1050 pixels. Is this a bandwidth or video card issue? Or both. Is 1920 x 1200 pixels just too much information to drive?
