i.MX 8M Mini 1440*1440 Display Support

[balogul]

Hi,

We are designing a device that will run on Android 13 OS with the i.MX 8M Mini. According to the datasheet it supports up to 1080p (1080*1920) 60fps display through MIPI DSI.

I assume that it could support 1440*1440 display with 60 fps as well since total number of pixels are the same for both but I wanted to be sure before we move forward.

Thanks.

Hi @Sanket_Parekh,

Thank you for your response. I hope you are doing well too.

So, it also supports 1440*1440 pixel display as well, correct?

Thanks.

Hello @balogul,

I hope you are doing well.

So, it also supports 1440*1440 pixel display as well, correct?
->No, It will only support as mentioned in the above thread.

I hope this answers your query.

Hi,

I appreciate the help.

1080p means 1080*1920 pixels which is equal to the number of pixels for 1440*1440 display. Technically, if it supports one it should support the other as well.
So I would appreciate if you can double check this information.

Thanks.

Hello @balogul,

I hope you are doing well.

Yes, you are right, Your logic makes sense in terms of total pixel count.
In general, resolution support is determined by the display controller and the associated drivers.

->While the total pixel count might be the same for both 1080p (1080x1920) and 1440x1440 displays, there are other factors to consider, such as aspect ratio, pixel clock frequency, and the ability of the MIPI DSI interface to handle the desired resolution.

It is not supported, only supported pixel formats are mentioned in the above thread.

I hope this answers your query.
