've got a 17" MacBook Pro, native resolution 1920x1200, which is quite high in terms of pixel density (132 PPI). I have a 24" external Samsung display, also 1920x1200, which means the pixel density is a lot lower (94 PPI). It works fine, but (as you might expect), screen items increase in size rather noticeably when I drag from the laptop display to the external display. (The 24" LCD Apple Cinema Display is also 1920x1200, so also 94 PPI and the same thing would happen). I've been looking all over the place, and I can't seem to find an external display in the 20-24" range that has a resolution higher than 1920x1200. Ideally I'd like to find a display with the same amazing pixel density, so everything is the same size on both my laptop display and on the external display. I don't know what that would be--probably something like 2048x1152 on a 20" or 22", and 2560x1600 for a 24". Even Apple's 30" Cinema Display at 2560x1600 (or what I imagine will be the new 27" LCD coming out later this summer, probably at 2560x1600) would suffer from this problem, because while the resolution is great, the screen size is so large that the pixel density would still be lower than 132 PPI and once again screen items would increase in size when moved from the laptop monitor to the external monitor. I don't really care about screen size or cost. I'd buy a 20" display, or a 30" display, if the pixel density were identical to (or at least close to) the pixel density of my MacBook Pro. Anybody know where I can find something like this?
