Notice

The LVDS to HDMI Adapter Board has been updated to the latest V1.5 version at May 10th 2021, we are trying to solve part of the compatibility issue. But according to the feedback there are still compatibility issues.
Due to the wide variety of screens on the market, the EDID recognition of different screens may have compatibility issues, which may lead to incorrect screen colors or abnormal screens.
This board is limited to LVDS output, the resolution must be the VESA standard, and the driver board should be at least V59 grade, or the driver board is not available.
Pin Connection: 2 x 40Pin
Because it is the DIY product, so sometimes there may be the compatibility problem. When it shows no signal or no sound, it may be the compability problem.
It is not recommend to use with 4K TV as it may have some compability problem.

FAQ

Q: Why the image cuts in and out? (screen flicker )

A: The mainboard LVDS output need to turn off NOSSC(Spread Spectrum function) and turn on the FREERUN function. The mainboard does not turn off the NOSSC, the frequency is unstable and the screen will flicker.

Note: If you use the ARCADE1UP machine, you may not able to turn off Spread Spectrum function, as it is NOSSC is a software function of the mainboard, the ARCADE1UP machine is a finished product, please understand.

Q: Why a yellow screen? (a yellow tint; yellow colors;Outputs yellow signal )

A: This is an EDID compatibility problem, because there are too many types of screens on the market, the EDID recognition of different monitors may be wrong, resulting in incorrect colors.(This issue maybe fixed by modify the program.)

Q: Is there a way to reflash the firmware on this board so it turns the Double 8 to a Single 8?
