Switch Aten CS1964 Video DynaSync question

Can the Video DynaSync feature on the Aten CS1964 be disabled for one of the connected PCs?

I have one PC that I would like to use the the feature for and one laptop that I do not want to use the feature for. Basically I have a work laptop that I need to be able to use the laptop's built-in screen to keep an eye on things while I'm using my personal PC, so I don't want monitor emulation for the laptop specifically....but I do want monitor emulation for my personal PC to speed up switching and keep all of my program windows where they were when I switched.

 

Here's my current setup:

• Personal Computer (Win10-64)
  • GPU - XFX RX-580 GTS XXX 8GB - it has 3x DP 1.4 and 1x HDMI2.0b and 1x DVI-D.
• Work laptop is an HP EliteBook x360 1030 G3 (Win10-64)
  • I'm using an HP Thunderbolt Dock G2 to connect the monitors.
• I have 3 separate single-display KVMs (no EDID monitor emulation) driving 3 monitors and use keyboard hotkey to switch the monitors and keyboard/mouse between computers.
  • Startech SV231DPU2 DP KVM #1 connected to Monitor #1 - BenQ GW2765
    • PC DP output #1 @ 2560x1440 60Hz
    • Laptop Dock DP out 1 @ 2560x1440 60Hz
  • Startech SV231DPU2 DP KVM #2 connected to Monitor #2 - BenQ GW2765
    • PC DP output #2 @ 2560x1440 60Hz
    • Laptop Dock DP out 2 @ 2560x1440 60Hz
  • TrendNet TK-222DVK DVI KVM connected to Monitor #3 - Dell 2407WFPb
    • PC DVI-D output @ 1920x1200 60Hz
    • Laptop Dock > USB-to-DP adapter > DP-to-DVI-D adapter @ 1920x1200 60Hz

When I'm using the laptop with the KVMs, the built-in screen is disabled and I'm only using the external monitors attached to the KVM. Unless I manually change the laptop's display output settings prior to switching to my other PC, wouldn't the built-in screen stay disabled since the DynaSync is making the laptop think the monitors are still connected? If that assumption is correct then I don't think the CS1964 will work for me. I think I need some type of device that can provide EDID monitor emulation only for my personal PC, then after that device I would connect it to a "normal" KVM that doesn't have always-on EDID monitor emulation. Does that sound right?

Regarding always-on EDID monitor emulators, I think I've found some products that would work, but would love to have confirmation:

• For the DisplayPort monitors running at 2560x1440 @ 60Hz, so far I've found these two:
  • https://store.level1techs.com/products/dp-repeater-hdmi-splitter only advertises 4K@60Hz resolution so I assume it could handle 2560x1440 @ 60Hz, but I can't be 100% sure.

• For the DVI monitor,

I'm also having frequent issues with my monitors and/or keyboard/mouse not reconnecting correctly when switching between computers. Usually it's just one single KVM acting up at a time, but all 3 of them do it seemingly randomly. Sometimes I can just switch back and forth again and it'll fix itself, sometimes I end up having to power drain one of the computers and/or monitors, and when that doesn't work I end up having to disconnect and then reconnect all display and usb cables from the KVMs and fully power drain the computer that's having the problem. I would love to figure out how to eliminate those issues. I'm thinking that the aforementioned always-on EDID emulators on my PC's video outputs might help with that. So unless somebody thinks that won't work I think I'll give it a shot.

If that won't/doesn't work then I think my next step would be to try to get rid of the 3 separate KVMs and buy a triple-monitor KVM as that should reduce the failure-points. I couldn't find any triple-monitor KVMs that have 2x DP and 1x DVI, so I was thinking maybe I could get a triple-monitor DisplayPort KVM (basic kind without EDID-monitor emulation) and then use that in conjunction with the previously mentioned always-on EDID monitor emulators on my personal computer's video outputs. I believe this would give me all of the functionality that I am looking for.

Thoughts?
