Notice from Drapak:
Use this manual at your own risk.
There could easily be translation errors in this document.
I scanned the original Chinese instruction booklet that came with my LVDS tester.
Then I put the images through optical character recognition.
The resulting Chinese was put into Google Translate, and then lightly cleaned up by myself.
So expect plenty of opportunities for mistakes to happen. Mind you, this is better than nothing!

Instructions for use
01. The LVDS screen tester adopts brand-new hardware and software, and all output ports are designed with short-circuit protection function to reduce the failure rate.
02. It integrates LVDS signal output with multiple resolutions, built-in professional LCD test screen, can increase parameters and reduce screen parameters, modify programs, and customize designs according to customer needs. Please contact the sales agent for consultation.
03. When using, just according to the resolution of the LCD screen and the number of screen lines, compare the screen parameter list, press the plus and minus keys to select the appropriate value on the digital tube, connect the screen line and backlight, press the power switch key to restart Just power on.
04. To replace the LCD flexor during the test, just press the power switch key to disconnect the power supply without taking off the power adapter.
05. Screen switching key +: It can cycle switch various test screens built in the tester.
06. Screen switching key-: It can cycle switch various test screens built in the tester.
07. Automatic switching key: Built-in multiple test screens are automatically displayed in a loop. At this time, the digital tube will display "AU".
08. VGA INPUT interface: plug in the VGA signal line of the computer, and automatically switch to the external VGA signal input, so that the screen displays the male face of the computer.
09. DEBUG PORT interface: Debug port, open to friends, not open.
