Part Number: TFP410
Other Parts Discussed in Thread: TPD12S521

Hello. I am using TFP410+TPD12S521 with HDMI socket .

1080P@60hz has a display on some monitors, but it is not useful on many HDMI monitors.

I don't know how to make changes? Is the edid problem? I hope to use the hardware configuration directly without I2C. The schematic is as follows. Hardware configuration circuit is as follows.

ISEL/RST# 0

BSEL/SCL 1

DSEL/SDA 0

EDGE/HPTLG 1

DKEN 0

Hi Feng,

Is HPD on the HDMI connector on the monitor side 5V for the monitors that do not display correctly? Can you try supplying 5V to it?

Regards,

I.K.

Hi Feng,

Do you mean you have applied 5V to HP_DET (HDMIOUT_HPD)? Did this fix your issue?

Regards,

I.K.
