Looking for any advice on connecting 5 monitors to a single PC - I want best of both worlds 
What I want is my flight sim setup connected as well as having the option to game on a separate 5th monitor and I’m very confused on technically how to do this or what is possible.
Flight Sim Setup as follows
Main Screen = LG CX 48" 4K TV (this sits behind my home-made cockpit) HDMI
Air Manager Screen = 24" 1080p Touch Screen for Air Manager (part of cockpit unit) HDMI
RealSimGear GNS 530 = ~6" Screen built into GNS (part of cockpit) HDMI
RealSimGear GNS 430 = ~5" Screen built into GNS (part of cockpit) HDMI
Gaming Setup
Main Screen = Asus 27" 1440p Monitor DP
When using the flight sim, I do not want the Asus monitor in use, and likewise when gaming I don’t have any of the flight sim monitors running so I get the best performance from the RTX GPU.
I have on-board integrated GPU with HDMI and DP connectors
I have a RTX3090 with 2 HDMI and 3 DP connectors
I also have a DP to 3x HDMI powered adaptor
I tried running the flight control monitors (GNSs+AirManager) connected to the DP to HDMI adaptor from the DP on the motherboard (integrated), but it seems only 2 or the 3 get a signal. I have also considered getting a USB-C to HDMI adaptor but not sure technical limits I may be hitting.
I do want the LG and the Asus monitors to be driven from the RTX3090 to get the best framerate in gaming or flight sim 2020
I did have this working by unplugging and re-plugging monitors but is it a pain and not sure the connector hardware will last, so want a more elegant solution if possible?
Thank you for any advice to how this can be done.
Disable your on board graphics totally, then plug everything else into your 3090. I used to run 5 1080p monitors on a 1080ti card and the machine never broke a sweat. If you dont diable the onboard card in bios it will slow you down.
You can buy adapters to convert the dp to hdmi if you need to if monitors dont have dp inputs. Same with using the mini dp ports.
Good luck, if your gonna buy adapters keep in mind which end needs to be what, ie you dont want to buy a hdmi to dp adapter when you really need to buy a dp to hdmi adapter ;p
If you have a local computer store its best to buy this stuff there, since if you make a mistake you can take it back and exchange it in person instead of waiting days, weeks etc.
I currently use 5 monitors, though it must be stressed that I only use the 27 inch 1440 for the sim itself. New PC runs this, a 15 inch touchscreen for the GTN650 and 750, a 22 inch 1080 for Navigraph and my old PC runs 2 x 23 inch 1080 screens for LittleNavMap and anything else that is useful.
PC one has the 15 and 23 inch via integrated graphics and the 1440 runs by itself atthe moment from the main GPU.
Stands for this lot were upgraded to gas arm monitor lifts. All works rather well really. Apart from the electricity bill.
Thanks for the tip, but I wanted to try and do this all on one PC if I could. I know I can move AirManager to its own PC or even a Pi device I believe which would be my second choice if I can’t get the setup on one PC.
Not sure about your card but the Asus RTX3090 only supports 4 monitors even though it has 5 connectors which is why I opted to use the onboard integrated GPU as well. My goal was to have as few monitors on the 3090 as possible so I had the best framerate.
I have 4 monitors. 55 inch OLED main, and 3 15.6" touchscreen monitors. Also have a 27" gaming monitor for non sim.
Good hint is that if you press and hold windows key and press P you can switch between single gaming monitor, single tv or extend or duplicate mode.
When gaming choose your gaming monitor only, when simming, choose extend.
When in extend mode, goto windows display settings and you can select your gaming monitor and choose “disconnect this display” instead of “extend to this display”.
Windows remembers which displays to extend to and which to disconnect in extend mode, so next time you press win+P it’ll auto turn off your gaming monitor.
I don’t THINK you can have more than 4 though, as whenever I try to extend to my other monitor too, it’ll extend to it, but disconnect one of the other monitors.
4 at a time definitely works though.
If you do need other things, you can always use a separate tablet.
I actually have a separate tablet to one side that I use as a digital notepad (just using ms paint at the moment haha) so I can jot down basic info like frequencies and headings etc.
I’ve been running some benchmark software and it seems like the overall performance is not impacted by having multiple monitors attached to the RTX3090. For now, I think I’ll put 3 of the monitors on the RTX3090 and 2 on the integrated GPU and do some more testing. I’ll also try the tip about using Windows+P and the disconnect option. Thanks!
how you communicate between the two PCs?
as i want to use 6 monitors on 2 PCs but I don’t know how to do it yet.
At the moment, I am effectively only using 3 monitors on each, but most 9f the time, I only need to run one PC as I cam get everything I need on one. Not always, but most times.
you using two PCs at the same time?
The sim and associated progs run on one PC and side functions such as Navigraph, Checklists and other stuff can run on the old PC.
