I’m looking at a number of options for a triple screen setup in 2024 at the moment, and my biggest concern is whether I would be able to drive them and get a reasonable performance. I have seen such setups on YouTube but many are with GA aircraft, possibly default, and things seem to be OK. What I need to try and ascertain is whether a successful outcome could be achieved with the PMDG 737 at an international, third party airport. I’m pretty sure, willing to be corrected, that this wouldn’t be achievable without frame gen. So…. is there anyone using this kind of setup with triple 4k, 47” monitors? Big question… does frame gen work across all three monitors, as with 2020, this is not the case?If so, what are the practicalities? BTW, my hardware is pretty beefy, based around RTX4090, specs in signature. Thanks.

Up until a few months ago I was running a triple 43" 4K monitor (plus a 1440 monitor above them) setup on a 4090. I never used the 'separate window' option or whatever it's called that renders each monitor individually because the proportions never looked right and performance was terrible. Instead I used NvidiaSurround to create a single large desktop (this also lets frame gen work across all three whereas, as you mentioned above, pretty sure it will only work on the center monitor if you run as separate windows) and initially tried running full screen on that at 3x4k resolution; that too had lower performance than I wanted so I then settled on running in a window of 2x4K size, thus leaving the sides open for other apps. This also helped minimize the stretching that gets really extreme at the edges of such a high resolution like 3x4k. I also then upgraded to a 5090 and this helped a lot also, giving me another 25 to 30% FPS across the board.

Then I found a deal on an Acer 57" ultra-widescreen monitor (2x4K) and traded that for my triple screen setup. The advantage there was that it was one seamless window with no bezels. I used that for a few months but then the narrow height of the monitor compared to the 43" monitors I was using before, and the stretching that remained at the edges, motivated me to buy the LG 45GX950A '5k2k' monitor and I think I've finally found my sweet spot! Compared to the Z57, I get 25 to 40% better FPS, and of course there's vastly less stretching at the edges. 

Certainly in terms of 'wow factor' these two changes both looked like downgrades, but overall I'm quite happy with my current setup. I realize that doesn't necessarily help you but just thought I would share my experience.

Overall, I would say a 5090 can adequately run a triple screen 4K setup if you're willing to drop LODs etc., but is definitely improved by trying the 2x4K window option I was using.  A 4090 is, at least in my experience, marginal for 3x4k, but I know other people have found it acceptable so maybe I just have less tolerance for low FPS.

Hi Rocky,

I run seven monitors on one computer when I run MSFS2024, I believe this video should give you an idea on performance. Although I don't run a 3D flight deck. System specs shown below.

Just getting ready to fine tune Nvidia Control Panel, right now, it's all default. Hoping to remove the remaining flickers.

my modest system: 4070 12 GB, 5800X3D. 64 gb RAM DLSS 4.5 antialiasing (not TAA). 2X frame gen.

I run two 32" 16X9 1440p montitors = 32X9. Or alternately Pimax Crystal Light VR. Very happy with performance.

I get about 40 fps , both LOD's 150.  I have no headroom to do a higher resolution VR nor for to do two 4K monitors. It would not perform well enough to do that.

With DLSS 4.5 and preset M, the ghosting on glass screens is way less of a problem than it used to be. Hardly worth mentioning, in my opinion. If someone offered me $1000 for 100 tests each, of whether my antialiasing is set to TAA or DLSS, I would guess right 50% of the time. Pure chance. The difference is too small for me to know for sure.

Great feedback and info Greg, many thanks for the detailed info, very helpful.

Cheers for the link Mike. I’ll check it out, looks interesting! I’ve seen your setup before, always blown away with it! You must be very proud of it… well done my friend. So how do you run seven monitors on one computer? I’m guessing they’re not 4k?

Hi,

I run my three 75" monitors at 2K and the Capt. PFD/ND 1366x768 via the Asus 4090 video board, the upper and lower MFD at 1366x768 via the Gigabyte motherboard HDMI and display port connectors and the seventh monitor connects via VGA to USB at 1366x768.

I run 3 x 43 inch TVs off my new gaming laptop with a laptop 5090 (read detuned 5080 with more VRAM).  Runs very nicely with the center monitor on 4k and the others on 2k.  It appears to me that FG, as well as DLSS, is working on all three.  

My new setup is 9950x3d / 5090 / LCS

3x 75” 4K tv’s

The amount of pixels that have to be calculated is enormeous.

With medium settings there is a 30+ framerate possible.

Regarding FG : when I used my former 2x 4K setup, I used FG 2x on ( which only doubles the framerate on the main monitor ) and Losless Scaling to double the framerate on the other.

Because of building my new 738 2 pers cockpit, the system is currently not working.

If the 3x 4K Config does not give me the detail and performance I want, I will add my Left View client again to drive the left view by using Wideview.

 

This video might also help : 4K main view and side views 1080p VS 2k vs 4K

Hey Mike, may I ask, what brand are the three 75” monitors? Cheers.

Thanks Gerard. I’ll check them out.

Hi,

I run three 75" Samsung UHDTV's, they are just about ten years old. I'll be replacing them in the near future with 86" sets. Main feature I want going forward is anti glare. Don't think screen burn-in is an issue anymore, but I'll look for screen burn-in protection going forward as well.

Thanks Mike. Sure, the anti reflection/glare is a must for me. I’ve been running an LG Ultragear 48” for the past few years. A silly amount of money, but a beautiful monitor, made moreso by not having to worry about screen reflections. So I realise that while this attribute is a priority, it will nevertheless restrict my choices.🤔
