If you 100% that DP will stack/daisy-chain for dual monitors, maybe you don't dual dp kvm, a single DP kvm would be enough?
Why do you need to connect avr output to 2nd monitor?
Yes a single out DP would suffice if I am daisy chaining.
The AVR out to 2nd monitor is for listening to music, browsing and watching videos. The TV won't work out for that.
So I have 3 scenarios,
1. Typical Home Theater env from PC for movies (TV is used).
2. Music from PC, and browsing (Monitor is used).
3. Use PC as a work environment (Dual Monitor is primarily for this).
The 2 issues I have is,
1. Receiver accepts HDMI, but daisy chained dual monitor requires DP.
2. I need to switch between home PC and office Laptop.
One other choice that will simply everything is, run a DP cable from PC to monitor. So monitor will have one input as DP, and one as HDMI, now I can switch using the monitor.
But, I have the problem of integrating the 2nd PC here.
