HDMI Output Cherry Trail

[GNass]

We're looking to set the primary monitor of a cherry trail tablet we use in an embedded device we are developing.

Unfortunately the option is not present in the BIOS. I'm not entirely sure how to attack this.

The options in the BIOS allow for the primary monitor to be set to the the HDMI port or an external display port but not the internal LCD.

We need the display to be locked to the internal LCD before the OS. For some reason the cherry trail platform defaults the display to the HDMI port rather than the internal display if it's populated.

Is there an option that can be set, modified, changed in the BIOS or through a tool that can help us solve this problem?

Many thanks

Hello, BLD :

On the other hand, it is important to let you know that unfortunately the Cherry Trail is on the "off-roadmap" and its support is for limited manufacturers. For this reason, this processor family is unsupported by this channel. Click on https://ark.intel.com/products/codename/46629/Cherry-Trail Cherry Trail website to learn more about the specifications of this family.

We hope that this information is useful to you.

Best regards,
