Board can't detect large monitor 32:9 on boot #35

Closed HungryNomad closed 1 year ago

HungryNomad commented 4 years ago

I have a Samsung 49" CRG9 Dual QHD 5120 x 1440 (LC49RG90SSNXZA) On a fresh boot, the Latte Panda 800s will not connect to this monitor. Other systems work with the monitor and the Panda works on other monitors.

The workaround is to connect the Panda to any other monitor or have the CRCG9 in PBP mode (Smaller resolution 16:9) while it's booting. Once at the BIOS or OS it can then be plugged into the CRCG9 in regular mode and it will work fine.

Hi there We check the spec of the screen. and sorry that we cannot point out the compatibility problem is cause by the Dual QHD or HDMI2.0. Do you have a type-c hub ? Maybe you can test the DP function in LattePanda type-c port?

Best Regards,

On further testing, it looks like if the LP800s is not plugged into a display through HDMI on boot, then it will disable that interface.

Either not plugged in or not detected at boot disables the interface preventing the OS using that output.

Please test it on your side. Power off the LP, disconnect the HDMI, power it on, wait 5 seconds, then connect the HDMI. Does the display work? Is this a firmware issue? Or specific to my board? I've also already defaulted the CMOS settings.

Hi there, In the first few seconds of booting. the board will initialize and detect peripherals. In the period， any change of peripherals may cause the failure of initialization. So if you need use HDMI port. We suggest you can plug before powered or after the LattePanda totally boot-up(Waiting for more time). Also please check the RTC battery still have enough power.

Best Regards,
