This frame, like several of Kodak's other frames, is a Touch Border model, which means that you touch the bezel of the frame to access menus and settings. With this frame, the various touch points along the bottom and right side of the frame light up when you touch the bezel. You have to touch the border next to the icons that appear on the screen. For those used to dealing with a touch-screen display, this won't seem intuitive initially, but once you get used to it, the system works pretty well. (We've seen some comments about the Touch Border not being senior-friendly, but anybody who reads the instructions should be able to get the hang of it fairly quickly.)
As for resolution, you're looking at 480x234-pixel wide-screen display. Kodak calls it "vibrant." That may be so (you can adjust the brightness), but sharp it isn't--which is to be expected from a frame with a relatively low pixel count.
The frame displays only JPEG still images--no video or audio. For moving pictures you'll have to step up to one of Kodak's higher-end frames that also have small, built-in speakers for sound. Pretty much all you can do is set the types of transitions you want in the slideshow (nine options are available, including "random" and "none") and set a timer to activate the slideshow during certain hours (a clock is built into the unit). You can also set your pictures to display in their native 4:3 aspect ratio or have it fill the entire with a little on-the-fly cropping of the picture.
The images we looked at on the frame looked OK from a distance of 4 or 5 feet, though it has a very small dynamic range: whites get blown out and skin tones are a little off. Get closer, however, and your images can look a little soft and pixelated because there's just not a whole lot of resolution to work with (you can see individual pixels). As is the case with all these lower-resolution frames, close-ups look best; there's not a lot of detail in subjects standing farther back or background imagery. Also, you'll get stair-stepping (read: jagged edges) in curved lines, such as the profile of a subject's shoulder. Finally, though the frame can operate in vertical mode, because it's so small it has a narrower off-axis viewing angle than usual in this position; the picture completely inverts/disappears when viewed from the side.
In sum, the P720 is a basic photo frame that's designed to be relatively affordable and easy to use. For about $70, it's an OK value, but if you're looking for better image quality, we strongly recommend spending the extra dough and stepping up to a larger, higher-resolution model.
