Sometimes drivers have issues too FYI. Kinda limited to laptops though. Mine doesn't change to external display/TV even with FN + F6(or F7/F8 whichever) and need to configure in the drivers.

Anyways, the 2253LW is tempting. Less 0.4 inch, but cheaper by a huge margin. I know I asked this before, but does it show some buzzing sound below a certain brightness/contrast level?

You need to increase your mouse sensitivity. You used to run at 800 x 600. Now it's about double the resolution to cover. Consider doubling your sensitivity or something.

As to the small icons, moving from such big ones to smaller ones, your eyes would take a while to get used to.
