TI中文支持网Part Number:DS90UB929-Q1EVMOther Parts Discussed in Thread:ALP
Our environment as above pic, I want to show my pc screen on the LCD.
The LCD is 1920*360, and we fail to show pc screen on LCD.
I can show color bar on LCD by use pattern generator on 929EVM.
Above pic is the setting in ALP HDMI page.
The active video show 1280*720, it's not fix to our LCD, any setting need to change?
Or there are any register need to set?
Is there any document about HDMI input operation?
thanks

Hello, what the Information Lab appears the detected input HDMI information, that can't change.
You could change the LCD resolution, doesn't it ?
In addition, if you want to use the Pattern Generator tab in ALP, it can change the resolution like this:

Hi
Is the bottom-left corner is information Lab? It's show ALP Framework – Hardware Connected.
Our product LCD resolution is 1920*360, couldn't change.
1. I success to use pattern Generator and change the resolution on 929EVM pattern Generator tab. I can show color on LCD.
2. I fail to use PC HDMI input on 929EVM and show the PC screen on LCD.
My question is any setting need to modify when use HDMI input?

Hello, there is no idea to change input HDMI resolution on DS90UB929 side.
For example, PC connected the UB929, if we want to change the input resolution, we should change the PC resolution as the above image listed. There is no related configuration of UB929 to change the input resolution.

hi
any other register need to set?
for example, EDID setting?
,
Kailyn Chen：
If you want to write assigned EDID to internal SRAM, you can use both EDID_SEL & REM_EDID_LOAD in mode_sel0/1 ( can use either strap or register setting) to choose the EDID from internal SDRAM, in this way, your HDMI source can read this assigned EDID through DDC. Detailed solution as below:
The process for reading EDID SRAM is as follows:
1. Write to APB_ADR0 to set the 8-bit register address.
2. Set the APB_READ bit in the APB_CTL register. This will initiate the APB Interface read.
The APB_ENABLE bit must also be set during the APB_CTL register write, while the APB_SELECT bits must be set to 01. If desired, the APB_AUTO_INC bit may be set to enable the auto-increment function.
3. Read the APB_DATA0 registers.
4. If APB_AUTO_INC was set, the next register location may be read by repeating steps 2 and 3, otherwise repeat steps 1-3 to read another register location.
The process for writing the EDID SRAM is as follows:
1. Set APB_ENABLE in the APB_CTL register. This bit should remain set through remainder of procedure. The APB_SELECT bits should be set to 01. If desired, the APB_AUTO_INC bit may be set to enable the auto-increment function.
2. Write to APB_ADR0 to set the 8-bit register address.
3. Write the 8-bit data to the APB_DATA0 register. The APB Interface write will occur once APB_DATA0 has been written.
4. If APB_AUTO_INC is set, the next register location may be written by repeating step 2, otherwise repeat steps 1 and 2 to write another register location.
