Does i.MX6DL's HDMI support 4k x 2k resolution?

[chaohuang]

Hi, Everybody

     I see the spec that iMX6's hdmi support 4k x 2k video format. But I can not see it in 33-3 table.

     My question is whether iMX6's hdmi support 3840x2160@30hz resolution(the fps can be less than 30)?

     Thank you in advance for your answer.

Regards,

Chao

HI Chao

unfortunately not as IPU max. supported screen size: up to 4096 x 2048 pixels,

HDMI is connected to IPU as shown on p.15,17 presentation

Hi, 

I tried to create a screen of 4096x2048 with fbset on wandboard with iMx6DualLite : 

 - fbset -g 4096 2048 4096 2160 32 -t 4500 4 4 4 4 12 4

I have some error with DI0 counter because the DIO counter have only 12 bits resolution (DI0 Sync Wave Gen 2 Register 0).

imx-ipuv3 2400000.ipu: DI0 for 1 counters out of range.
imx-ipuv3 2400000.ipu: DI0 for 2 counters out of range.

So how i can create a screen of 4096x2048 resolution.

Thanks

Julien

Bnd if I don't use IPU to draw the picture, should it support the 4k x 2k resolution?

Thank you!

Thank you for your kindly reply! But I am curious about that why some background of the resolution is green and some about white and blue in p 15 of the Document? I can not see any explain in that document... Do you know what does it mean?

Thank you!
