Display
The display resolution represents the amount of pixels that make up the image. It is a key indicator of image quality, with higher resolutions providing sharper and more detailed images.
The type of technology used in the display.
The bigger the screen size is, the better the user experience.
Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.
Pixel density is a measurement of a screen's resolution, expressed as the number of pixels per inch (PPI) on the screen. A higher pixel density translates into more clarity and sharpness for the images rendered on the screen, thus improving the quality of the viewing experience.

Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Newer versions provide faster data transfers.
With more USB ports, you are able to connect more devices.
Audio
If the device supports Dolby Digital it can deliver up to six different audio channels (sides) for a much better sound quality.
DTS Surround is a high-quality audio codec that supports up to six audio channels, with good bitrates and audio quality.
Audio output power is based on the number of speakers and their power in watts. High audio output power results in loud, clear sounds.
Devices that support Digital Out can deliver sound through optic fiber audio cables (like TOSLINK) or coaxial audio cables, which can transmit high-resolution audio at fast speeds.
If a device supports Dolby Digital Plus it can deliver up to fourteen different audio channels (sides) with improved bitrates, for a much better sound quality.
SRS devices create an immersive 3D soundfield using only two speakers, simulating the kind of audio experience delivered by devices that support Dolby Digital.
Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
Dolby Atmos is a surround sound technology that allows sounds to be interpreted as three-dimensional objects. By doing so, Dolby Atmos allows for immersive, 360-degree sound.
DTS-HD Master Audio supports unlimited surround sound channels and lossless audio. This standard delivers one of the best possible audio qualities.
