Display configuration using kernel parameters

Hello

I’m specifying the LCD settings using the kernel boot parameter : «vidargs=video=mxsfb:480x272M-24@60». Can you tell me which exact LCD parameters are taken in that case?

I’m interested in knowing which exact values are taken for the following parameters:
clock-frequency
hactive
vactive
hback-porch
hfront-porch
vback-porch
vfront-porch
hsync-len
vsync-len
de-active
hsync-active
vsync-active
pixelclk-active

Kind regards,
Michael

You can use fbset to show you lots of values.

Hi @michaelg !

Please refer to the Display Output, Resolution and Timings (Linux) article, on the iMX7 related section.

It indicates to setup the display in the Device Tree.

Also, each display has specific timing configurations that you need to grab from its datasheet.

If you are using a display supported by Toradex (Supported displays), or provided by Toradex, you can find the datasheet on the display’s page.

Best regards,
