This is a pretty monitor for RPi, which has high performance and is convenient to use. 

First of all, about its performance. The display part comes with a 7" TFT screen, which has a high resolution IPS with wide viewing angle.

 

HDMI/VGA/NTSC/PAL input sources are accepted.

 

How to use it? Just connect the included 9VDC adapter and video source, using buttons to adjust it to a comfortable setting. A basic stand is provided to fix it on the desk, or you can use the 4 'mounting thread' holes on the stand to attach the screen to other platforms. Also, there is a camera mount hole, which allows you to connect it to your camera to preview your pictures.
