Probly, it's about your card. nVidia GTX 260 does not support DX11, so maybe this is the main reason.
Because my card is GTX 680, absolutely support DX11 and when I set that "Configure Viewports" all to 4096pix, and load a 1920*1080 HD picture to a plane, there are no any problem with it. How you look from picture viewer, and how you look from that plane.
About performance, I have to say, Max2014 is the best performance of all version of 3dsmax. it cause DX11.
In my machine with nVidia GTX 680, I can handle 30,000,000 polys (60,000,000 triangulars) fluent with 4.87fps, and 100 million particles from PFlow fluent with 5.12fps what if I got a Quadro card with 3ds Max2014.
Before Max2014, more than 300,000 polys you will crazy about that performance. But in Max2014 with DX11, 4,000,000 or more polys just like knife to cut vegetables, so easy to handle.
So, Max2014 is really got big performance overflight. However, card itself about DX version support, that's other point.
I tested too, if alter DX11 to DX10 or DX9 in max2014, it lost all high performance and like old max, you don't hope to handle 30,000,000 polys fluent, maybe 3,000,000 polys max just like snail crawl, because without DX11.
