I have recently decided to attach my downstairs living room TV to my gaming rig that I have set up in my man space upstairs via HDMI/USB3.0 extension cables.

I currently have a ROG swift running off DP and a secondary monitor running via HDMI in the games room. I have my TV connected via DP to HDMI converter (my GTX980 has 3 DP's and 1 HDMI/DVI) and if I wanted to run the same screen on all 3 monitors there would be no issues...except I don't and this is where I'm seeking the knowledge of this great collective :D

I am looking to have the ROG swift as my main monitor, this must run of DP as I need the 144hz and 1440p which isn't supported via HDMI. I want the 2nd monitor in the games room to have an extended setup applied to it and I want the 3rd monitor (the TV downstairs) to clone the ROG swift.

As far as I am aware I cant use a splitter for this as the primary must run off DP and the TV HDMI.

Is there anyone out there with a solution to this? anyone know of any DP>DP+HDMI splitters? Any software that can be used that wont effect performance? :confused:
 
Please correct me if I am wrong.

So that's a typical two monitor extended display in the games room and your ROG Swift (Monitor 1 of 2 in games room) to be cloned on TV downstairs.

I am not sure that, is even possible. However maybe there is something within your Nvidia software that allows you to do it. You may not be able to do that with two GFX Cards let alone one.

Keep looking though and if you do manage to do it, please post your solution. Interesting idea you have there.

:)

EDIT - Maybe an active DP splitter could do it....but I'm not sure they even exist. If they do then that may be your best bet.
 
f.lux is just a program that reduces the brightness of your screen(s) so that it's easier on your eyes when it's dark or whatever, that part shouldn't have anything to do with it.

It sounds like something that should be easy to do, but I don't have 3 displays connected to see exactly how to do it :(.
 
Yes you guys understood correctly. Im going to investigate solutions futher tomorrow ( posting from phone atm ). Ill check out the w10 thing for sure and ill keep people updated if i manage to find anything. At the point of typing this an active display port splitter would appear to the most obvious choice if they exist.

On a side note if anyone cares, running hdmi and usb 3.0 cables with active capabilities is so far proving super effective in providing a hardcore gaming experience all over the house. If u can run cables through floors or ceilings like i have i would thoroughly recommend it.
 
I may be missing the point but this doesn't sound complicated.

Main monitor: Dp connected to your main monitor(monitor1)
Hdmi port on the cars itself: Games room(monitor2)
Dp-hdmi adapter: Tv(monitor 3)

Then in windows display settings:
Set monitor1 as main
Set monitor 2 as "extend desktop to this monitor"
Set monitor 3 as "duplicate monitor 1.

In windows 10 these are options and I'm sure its in other windows versions as well.

If for some reason default windows settings don't work, maybe try ultramon.

From googling it does seem like it's more complicated because pretty much all posts on the topics are talking about needing a splitter, I can't work out why it doesn't just work like the above though :(.

Ultramon doesnt support the outcome i require( have used ultramon for years) and the settings you have suggested that are native in w10 simply dont exist.

I have found that i can buy a dp splitter then most likely attatch a dp to hdmi converter to connect to the splitter this would let me use my rog swift and the tv at the same time in theory. The question is how much of DP bandwidth is consumed transmitting 1440p at 144hz? Will i experience degredation on any of the displays?

It exists in windows 7/8/10, I will find some screenshots.

Regardless, I realised I can help with this in practice instead of just theory. I have 4 monitors and a projector connected to my pc and main monitor is on dp @4k.

So when I'm home tonight I will try and replicate your setup by having my main monitor on dp, left monitor pretending to be your tv on HDMI duplicating the main monitor, then having my projector as extended via hdmi for your games room.

Will be the exact same idea, 1xdp, 1xhdmi duplicated, 1xhdmi extended.

Will post later if I get it to work. :)

Edit: I reckon if you did find an adapter for dp, you wouldn't lose much quality considering the mega 4k bandwidth the dp port provides which x2 1440 would fit within as it is the rough equivelent to 1.75x a 1080p bandwidth.

OK so home now and tested this.

What I have done is kept three of my monitors on only as I am trying replicate your setup:

So I have my main 4k monitor connected to DP
Right Monitor(lets say your games room) - connected to DP via a DP-HDMI adapter
Leftmonitor(your TV) connected to HDMI

So main monitor and left monitor(your main plus TV) are cloning each other, and I have the right monitor(games room) as an extended desktop:

Picture of desktop:

As you can see MSI afterburner is on the divide between main and right monitor, and the middle screen and left are duplicated with my middle monitor set as main and still on 4k resolution.

In addition if you didn't want to use the windows display controls - NVidia control panel has you covered as well: shown below:

Hope this helps as the setup I just made, matches what you stated in the first post.
