Video Display Chip Selection

Hi,


We have a high end workstation product which has 3 independent 4K displays run by AMD Radeon Vega Frontier Ed. GPU.

We want to display our logo animation on 3 displays during the startup sequence of the workstation, we dont want users to see the motherboard's post messages.

To achieve this, we think to use a breakout board between the GPU and the Display's driver boards which will switch between the logo animation and the gpu output for the 3 displays, we want to display 1 single video(it doesnt have to be 4k it may be 1080P) extended on 3 displays and when windows workstation pro. boots up it will receive a trigger from the OS and switch back to the gpu output and display the regular 4K gpu output(windows OS) on 3 displays. It is better if this switching can be done with fading transition.

Can you advise us with your products which will be needed for this application? Thanks.

    Hello,

    Could you please explain the expectations of the SoC? I am trying to understand the inputs/outputs, the display resolution/FPS and the GPU performance criteria.

    Regards,

    Hi Krunal,

    It will basically act like a switch between 2 video inputs, 1st video input is the output of the GPU, 2nd one is the logo video which should be displayed on 3 monitor. There are 3 4k outputs from the GPU which will pass through the soc, when system is booting(power switch pressed) it will switch to the logo video and display the logo in all screens, when boot up finishes OS will send a signal so that the SOC will switch back to the GPU input and display the operating system in 4K. the video playback resolution may be 1080p max. but lower is also ok the important thing is it should look nice on screens (for example video resolution will be 5160x1080 or 3840x720 or so on)and 23-30fps is ok.

    It is better if the switching from video playback to GPU output done with fading transition.

    There should be a video switch, video player and sd card for saving the video to be played on the SOC i guess
