Overview

S.EDP-HDMI-4K2K.V1.2 is a signal adapter board, which is mainly used to convert EDP signal into HDMI signal, the resolution of this adapter supports up to 4K 30HZ resolution. The adapter can be used in set-top boxes, advertising machines, conference systems and other fields. EDP input needs to comply with EDP1.1, EDP1.2 standards;

Update History: Update to V1.3 version from V1.2 version in December 2022, and add the EDP SET switch to switch 2LANE and 4LANE.

Important Note

1.For general computers or industrial motherboards:
These adaptive output motherboards typically support only 1080P(2 lane) or 4K(4 lane) resolutions. Resolutions below 1080p or equal to 2K CAN NOT be supported. To support 1080p resolution please make sure that the motherboard meets the 2-lane EDP requirement. Please DO NOT use it to connect your PC if the resolution of your screen is not 1080P or 4K.

2.For Android/Linux solutions from Qualcomm, Rockchip, Allwinner, or certain LCD driver boards:
These solutions usually use fixed output EDP signals. Make sure these signals can output standard resolution and refresh rates and adhere to HDMI timing specifications, then EDP to HDMI adapter will support 1/2/4 lane EDP signals.

FAQ

Expand

Q: The adapter board is connected to the EDP signal, but there is no HDMI output?

1. Please check whether the EDP cable is connected correctly, differential signal and power supply.
2. The power supply voltage should be above 4.5V.
3. EDP output to distinguish VESA compliance, refer to point 6 of user manual.

Expand

Q: The HDMI output picture is normal, but the color of the picture is abnormal?

1. The data format of the EDP signal does not match the configuration of the adapter board, single 8 or double 8.
2. EDP signal board need to adjust program or enter the factory menu to set EDP MAP (VESA or JEIDA).
3. The adapter board upgrades the program and reconfigures the parameters.

Expand

Q: The size of the HDMI output picture abnormal or the position shifted?

The EDP signal board should adjust the EDP parameters strictly according to the VESA standard configuration, refer to point 6 of user manual for common resolutions.

Expand

Q: The HDMI output screen jittery, flickering and other unstable phenomena?

Focus on checking the EDP signal parameter configuration, turn off the spread spectrum (NOSSC) of EDP output, and turn on the FREERUN function.

Expand

Q: Does this adapter support 1080p up to 240hz?

No, the adapter can only support 1080p up to 60hz.

Expand

Q:Using laptop motherboard, 4lane wiring sequence, connecting to 40PIN connector, can't light up the screen?

Because the laptop motherboard is adaptive output, the front 30pin interface interferes with the 4K60HZ high speed signal, so can not use 40PIN, you can only connect to the 30PIN interface. You need to redo the connecting wire. Please follow the 2lane's EDP screen specification wire sequence to make the wire and connect to the 2lane's interface.

I'm still trying to figure out how to plug in the edp cable into the board. Every time the wire makes contact, the board heats up and burns.
