[Feature Request] PIP/PBP Mode selection

[brunbjoern]

I would really like to see the possibility to select PIP/PBP modes via CLI. This would be really handy.
Don't know if this is possible via DDC.

I managed to do this with a Dell U4919DW. But I would assume it would depend on your monitor.
What I did was download this program ControlMyMonitor. This allows you to see the VCP codes. I saved the ones it showed me. Enabled VCP mode and saved another copy of the codes.
This showed me that the code for enabling PBP mode was E9 (0xe9) and for selected the secondary input E8 (0xe8) is used. I than added this to ddcctl on my mac and rebuilt it, works flawlessly now.

Would be happy to assist. You can also download the tool from my fork. and use the -pbp flag with a value of 36 to enable PBP mode. But of course, your mileage may vary.

My fork: https://github.com/itxchh/ddcctl

Just a note to say the above-mentioned fork (and its default -pbp setting of 36) also works with the Dell U3818DW.
