Hi,
I have a bit of an unusual question, and quite a long post, so please bear with me, but I'm hoping that someone might be able to give me some advice, and steer me in the right direction, as to whether what I'm trying to do is actually possible or not.

I have my gaming PC running a GTX 1070ti that we got at the end of last year, currently in the living room connected to the 65" Samsung Q90 TV with hidden usb cables going to 3 Rift sensors fixed at ceiling height. So I am using one hdmi output for the TV, and one connected to the wall plate that I plug the Rift h/set in whenever I am using VR. This all works really well. However, in my study I have a 2017 5k iMac that I use for video editing and general office work. It has occured to me the gaming PC is actually a better spec for me to use for video editing, with the 1070ti than the iMac is. Added to that my work are planning to prohibit the use of all pen drives that are not encrypted and purchased from them, and you guessed it, they refuse to make the dual format pen drive available only PC, so when this policy changes I will be unable to access work files from my pen drive on my iMac.

I have been trying to plan a solution to allow me to use the gaming PC in both the living room and the office, for both use cases, gaming and work. The sensor cables for the rift already run up to the floor above, where the study is. I would like to move the PC to the floor above where it is now, which is a large, well vented cupboard, near the study, and the rift sensors would all still be reached with their current cable runs. I should be able to run HDMI and USB cables back down to the living room without difficulty and would use a usb 3 hub in the living room for gaming keyboard and mouse. The problem comes with the study end.

I reckon I should be able to hide 2 hdmi and a usb 3 cable from the cupbard to the study, and if I use an active powered repeater cable to the hub at my desk all should be well, but I appreciate any input from anyone who has done something like this to keep me from any pitfalls.

What I am looking to do is find some way to have 2 separate windows accounts, one for office and one for gaming, which obviously is easy enough to set up. But I am looking for some way to have the gaming account only see the Rift and Tv screen, and the office account only see the other 2 displays. For work I use 2 displays regularly and don't want the chance of 'losing' windows on to another display I cannot see from my study, if that makes sense. Obviously, the TV will often be on while I'm working in the study.

Is this something that it is possible to set up in Windows 10, or is there any 3rd party software that will enable this? I have never tried to use 4 displays in Windows 10 in this way before, and don't want to start the large upheavel and expense of moving stuff and running new cables if it is not going to be practical to do. I think it would be a good solution, that would improve the video editing side of thigs and also allow me to play some games in the study when not able to use the living room screen, and the iMac even with a windows partition still wouldn't cut it for gaming. Another plus would be that I would no longer need the iMac which I could sell to offset some of the cost of PC upgrades going forward.

I hope I've explained this in a way that can be understood, and again I apologise for the length of the post. I really appreciate any advice or comments on the idea itself, anything I should be aware of, as well as advice on how to deal with the 4 screens: 2 screens to each windows user idea.
Thanks

Duncan

Moonbeam, the spec is:

Ryzen 5 2600 3.9 Ghz
16gb ddr4
512gb ssd
3tb hdd
GTX 1070ti (4 hdmi outputs)
Gigabyte B450

If I was to move the video editing over to this PC, I’d probably take the ram up to 32gb for rendering speed.

It's highly unlikely your GTX1070Ti has 4 HDMI ports (unless it's a specialist card). It's more likely to be 3 x Display ports and 1 x HDMI as that's the standard I/O configuration for most GPUs in the higher end category.

Your biggest issue will be signal degradation, as you'll have to use DP-HDMI adapters and a mix of cables. Cable length could also cause you problems. Active powered repeaters often don't work that well especially for DP/HDMI cable runs in excess of 10 metres. If it's shorter than that, you might be okay. USB also suffers from the same issues but if it works now it should still be okay if you are using the same cables for your Rift.

Are you planning to use the PC for both activities at the same time?

My mistake, it’s 2 hdmi and 2 DisplayPort.

I’m thinking I might just go with the 2 hdmi outputs and use a couple of bidirectional 4k 60 hdmi switches to switch between the rift/tv for gaming and 2 monitors in the study for work, might cause less difficulties.
