===Introduction===
[[File:LCD1.jpg]]<br>
This monitor is specially designed for Raspberry Pi. You're recommended to download and install the image we provide. It is written based on the Raspbian Jessie 2016-5-27 version and we've pre-installed the driver and pre-set the calibration program. So you can just burn it on your card for use. If you want to change the calibration, you can just find the program and alter it. <br>
Download the image at the bottom of the page, unzip the package downloaded and you'll see a .img file. Burn it to your TF card by win32imager.<br>
Next, connect the monitor to the Raspberry Pi, and the HDMI board. plug in the TF card with the image file burnt. Connect the power and you can start the use. 
Or, you may install the driver based on the instructions we provide in the package. <br>

If you have any problem, please feel free to contact us, by email to service@sunfounder.com or posts on our FORUM. We'll reply you ASAP. Thanks for support!<br>

Note:<br>
1) If you're doing this on an HDMI display, you're suggested to plug in the 3.5inch display into the Raspberry Pi. After the driver is installed and the Raspberry Pi is rebooted, you can see the 3.5'' screen shows the desktop of the Raspberry Pi, while the HDMI displays the CLI (command line interface).<br>
