Display Screen Ratio
This is the ratio of the width to the height of the display screen within the digital frame. There are mainly just 2 ratios which are 4:3 and 16:9. The best way to understand these is to compare them to television screen ratios. 16:9 is considered as wide screen and 4:3 is the same as the older almost square screens.
Display Screen Resolution in Pixels
When looking at a digital image or photo the screen resolution is what determines the quality of the picture you see. This is measured by the number of pixels (points of light) that exist to illuminate the display area of the screen. The number of pixels in the digital photo display are indicated by a multiplication of the width in pixels by the height in pixels. The large the numbers the better the quality will be.
Typical resolutions are 640~480, 800~600, 1024~768 and you will find many more in between. However it is a higher pixel density will give you a better quality image. So you need to consider both resolution and image size.
Digital Screen Size
The size of the digital screen is measured in inches diagonally. The screens on digital picture frames vary from about 4 up to 10 and now even 15, with the most popular being in the 6 to 8 rangeh.
Remember though that if two digital picture frames have the same screen size, but different pixel resolutions, then the screen with the higher resolution will be the one with the better quality image. For example a high resolution of 1024~768 would be better than 800~600.
This is the memory that is built-in to the digital photo frame and is measured in megabytes such as 256MB or 512MB.
The memory card slot on the digital photo frame is important as it determines the type of memory card you can use to load your digital photos or images into the digital frame. You need to make sure that it is the same type as the memory card you use in your digital camera or personal computer. If you get a digital picture frame with a memory slot that is not compatible you will not be able to load up your photos.
Examples are CF, MMC, MS, SD and Memory Stick
This is the type of file that holds your digital images and in most case will be JPEG files.
Some Digital Picture Frames will also be able to play video and you need to check that the video format of the videos from your digital camera or other source are compatible. Normally this will be MPEG.
A digital photo display may also have the ability to play audio such as music or speech. Typically these would be MP3 format files so make sure you check for compatibility.
For ease of use and total convenience many digital frames are now supplied with a remote control, so if this is important to you then make sure it is in your selection criteria. You may have to pay a little more but this is probably a feature most people would want.
A USD port will be essential if you want to use a USB Flash drive or Pen drive to load your photos into your digital frame.
USB PC Connection
Similarly a USB PC connection will be essential if you want to transfer your images directly from your own computer to your photo frame.
Bluetooth or Wireless Facility
You can now even use Bluetooth or your home wi-fi system to transfer your images, so look out for this if you need it.
This is normally a total necessity for everyone and will probably be found on almost every digital picture frame out there.
