They have a low
resolution 480x234 pixels. One of the few reasons
are, the aspect ratio of these picture frames is
16:9. Which means all your images that you load in
them will look elongated or squashed. However you
can make it fit the frame by cropping using a
computer and software. Plainly it is not as simple
as inserting your memory card and getting a
wonderful picture as you would get from a 5.6, 8 or
10inch screens. The other reason is the viewing
angle of the 7 inch frames is very narrow. To
illustrate the importance of viewing angle, consider
that you are placing a photo frame on your
mantelpiece. If you are setting naturally on your
sofa, your line of sight to the frame will be at an
angle. Unless the frame supports wide viewing angle,
your picture will appear blurred in most cases you
will not be able to see much. So if you are going
for a cheap frame, think about its usage, are you
going to place it on your desk and view it from a
close distance or will it be a decorative piece for
a visitor to appreciate. Electronic Photo Frames
like the 7 inch with narrow viewing angle produce
acceptable quality of the picture when viewed from
less than 1m from the frame, almost a distance that
you need to hold them in hand. Many of the cheap 7
inch photo frames do not support audio or video
playback. The support for different memory cards is
also limited in case of cheaper frames. To
appreciate quality difference you need to see the
same picture in a 7 inch frame and then view it in a
8 inch frame. The 8 inch frame or the frame with
higher resolution Digital signal and 4:3 aspect
ratio panel will always be much
better than a 7 inch digital photo frame with
low resolution and 16:9 aspect ratio. |
