Connecting two 4K monitors

Recommended Posts

Hi there. Since about 6 months I have a 32 inch 4K monitor. I can select the refresh rate 30 HZ on the monitor. In P3D I checked VSYNC and frames unlimited. It runs fine. I use a 11 GB 1080Ti GPU. In P3Dv5 I can see most of the time 4 to 5 GB VRAM  is used. I don't fly very complex AC. All ORBX regions and airports.

Now I'd like to add a second 32 inch 4K monitor; same brand and type ofcourse. 

My question: What does that mean for the load on the GPU? Second monitor doubles the number of pixels. Will the needed VRAM also be doubled? What will this in general mean for FPS?

Thanks.

Hi Rein,

Not sure I can anser that directly as I dont have a 2 monitor set up, but this post may help:

FPS is likely to be lower especially as the load on the GPU will be higher if it has to generate different sim views to different monitors. How much will depend upon your specific PC and setup, so hard to say what the actually drop would be. Running 2 monitors at 4K would  have an impact I believe.

You dont say what views will be shown on the 2nd monitor? If the 2nd monitor is used for a moving map display the FPS drop and VRAM usage could then be small but if you are using to show multiple cockpit/scenery views its likely going to be impacted.

 

Regards

Hi Mark,

Thanks for your reply. I have not seen the post at the P3D forum so I will take a look at that. My idea is to extend the view of the cockpit / scenery. So yes I will think it has an impact on fps. Okay, I'll start reading the post at P3d first.
