Hi NXP

About the dual display, we get more the request form our customer.

How to display same content on dual display in imx8mp / imx8mq?

The OS is Yocto 3.0 and Yocto 2.5.

Do you have any advice?

[joanxie]

do you mean video or UI? and imx8mq is different architecture from imx8mp

[charleshuang]

(1) If our request is play video on dual display, it's the same content on dual display (HDMI and LVDS).

In imx8mplus , how to do?

In imx8mq , how to do?

(2) If our request is the same UI content on dual disaply? How to do ?

[joanxie]

for imx8mq, you can use the command like

"gplay-1.0 /unit_tests/4K_AVC_24fps_22Mbps_AACLC_44.1Khz_2ch_Honey_bee.mp4 --video-sink="kmssink driver-name=imx-dcss" & gplay-1.0 /unit_tests/bbb_sunflower_1080p_30fps_normal.mp4
"

and imx8mq supports dual UI as default, for imx8mp, you can use mouse to enable the second display, then on the second display, you can use the gstreamer command or click the menu on the top left corner to playback

Hi NXP Team

Thanks for your reply.

Our customer feedback their request is UI  display content on dual display. 

In iMX8MP How to do ?

In iMX8MQ How to do?

[joanxie]

i.m8mq should support it as default, for imx8mp you can connect the mouse to enable the second display

[charleshuang]

About imx8mp you can connect the mouse to enable the second display, how to do ?

Our customer need  HDMI disaply the same with LVDS display.

[joanxie]

for dual clone mode, pls refer to the suggestion as below:

The main work is from weston user space, for imx8mp lvds and hdmi, there are two CRTCs("users can make the difference between guaranteed synchronized monitor timings (shared-CRTC clone mode) and not -- asynchronous clone mode (independent CRTCs).").

we don't have any sample code for customer, but customer can try this suggestion

Hi NXP 

So about the imx8mp dual display.

Nxp cannot provide the SOP porting and source code for display same content on dual display in imx8mp, right?

We need to response my customer.

[joanxie]

yes, just suggestion, don't have sample code for it, customer needs modify the weston
