Scan the many commercial sites that offer digital picture frames and for sure you will be overwhelmed by the number of brands and manufacturers that offer their products. Adding to your confusion is the fact that all these share the same design and characteristics and all promise to serve you with great services along the way. So what to do in extreme cases like this? One way to separate the oranges and the apples so to speak is to personally check these digital picture frames and evaluate their screen quality.

Why a personal check is recommended

You might be tempted to just check the information as given on your favorite site, or perhaps you will simply accept the facts and data that these sites offer you at face value. Don't fall into this trap; if you want better selections and you are intent on checking and getting the best picture frames then a personal check will do the trick. It's so hard to check the screen quality of digital picture frames if you don't have access to these products and you can't compare the many products side by side.

So it is suggested that you visit the actual store where these products are displayed and for sure you can find different types of picture frames that assume many designs. You will find varied types and designs; from the more traditional photo frames designs to the ones that incorporate traditional mats. The design considerations of these products may come in bare and truly functional designs to the more intricate ones.

What's screen size got to do with it?

Okay, back to the screen size. You have to remember that screen size and its resolution should be factors that should be checked when shopping for digital photo frames. Here is one key rule that you should follow when shopping for these toys; image quality will decrease as the screen of the digital photo frames gets larger. This is possible because the available pixels are then spread over a very large area. So make sure that you know the proper balance between screen size and pixels. In order to facilitate the proper selection of digital photo frames, you have to have some math skills on stand-by.

There is a way to calculate the pixel density screen. If the screen is 4 x 6 inches and the resolution of the frame is pegged at 640 x 480, just multiply the values and you get 24 square inches and 307,200 total pixels. Then you have to divide the total pixels by the area in square inches in order to get per square inch. Using that computation, you will get 12,800 pixels in every inch. Then get its square and you get 113. Now if you have at least two digital picture frames on the table, the one with the highest value should be okay. But remember that exact comparisons can be made on screens that are roughly of the same size.
