just adding that i personally can barely stand this game at native 1080p haha,
i notice a huge difference going to 130% scaling (2496*1404).
a lot of the games effects (SSR, SSS, AO) scale with render resolution, which can make artifacting less noticeable.
I did a direct comparison once
1080p 100% render scale
1080p 200% render scale
You notice it more in motion, but clearly visible in screenshots flicking back and forth
Okay.. I stand corrected..
Still won’t help on 2160p TV though. render it at 200% on 4K will burn the GPU.
Or a 2160p native TV, render at 1080p at 200% resolution, would still be worse than a 100% 2160p, right?
In general you will need one of the latest, top of the range Graphics Cards if you want to have a more than decent rate of FPS, say 30+. You will also want to ensure your TV is a good candidate for working as a PC Monitor, for this it should support Chroma subsampling 4:4:4.
There is an explanation and sample image you can use to check the configuration of the HDMI port you are using for your PC, on this web site, which was really useful when I was configuring my Hisense 43" (43R6+) which was a nice surprise, as it was one of the least expensive ones I could find at Costco in Canada:
There are some other articles about best TVs to be used as PC monitors as well on this website, in case you anyone is looking for one.
I suppose there will be some other compromises to be made when using a TV, but so far I find it a great experience, for FS 2020 and other games, as well as for coding, and other general activities you would normally use a PC for.
These kind of performance , feel free to check out my other videos. I’m running on 4K as well. Rtx 3090
It depends on your distance from the tv and the quality of the upscale / downscale process. However rendering at native resolution is always better than resampling in between.
It all comes down to the FOV you’re left with. The human eye can distinguish up to 120 pixels per degree (upper limit where people with great eyes can still ‘guess’ which image feels better), while 60 pixels per degree is regarded as 20/20 vision, good enough. (and is what all the recommended viewing distance charts are based on)
The formula for pixels per degree for a 16:9 screen is roughly
1080p: distance x 38.45 / diagonal
1440p: distance x 51.27 / diagonal
2160p: distance x 76.9 / diagonal
So for a 15.6" laptop screen, 24 inches away (2ft) gives you about 59 pixels per degree.
A 92" projector screen, 12ft away (144 inches) gives you about 60 pixels per degree.
Much bigger screen, same perceived resolution. And actually the laptop screen is ‘better’ in the sense that you can lean in to read the fine print without having to get up.
For the OP’s example going from 34 inch ultra wide 1440p to 43 inch 4K
As I understand it ultrawide 1440p is 3440×1440, 43:18 or 2.388:1
To compare, at a 5ft viewing distance, horizontal resolution for the 34" ultrawide would be 114 pixels per degree, for the 43" 4K tv 111 pixels per degree. Virtually the same, both at the upper limit of human vision.
So basically going from ultra wide to 4K you’re only expanding your vertical view, rendering more pixels for the same perceived resolution.
However you generally sit further away from a tv and closer to a monitor. Thus you can reduce the render resolution for the tv compared to the monitor, since you won’t see that extra detail anyway. Thus set the display resolution to 4K, but reduce the render scale the further away you sit.
Ok,
So today I got the 4K TV and hooked it up. All I can say is HOT DAANG. What a difference. The sim looks much more AMAZING. Everything is much sharper and cleaner. Well worth for the visuals.
Now for the performance, I don’t know if today’s update made things a bit better for everybody on performance, but I was able to stay on an average of 45-60 fps. Sim actually seems to perform better on 4k. I guess it’s true what they say about the 30 series cards performing better at 4k. Or maybe it’s just the update that made things better. Really can’t say. But in some instances while on the ground I would see 35 fps. But mostly 40-45 fps on the ground. While in the air it was between 40-60 fps. This was while taking off from KATL. I set my settings to native resolution and the render to also native resolution. With mostly ultra settings including clouds and some high settings.
All I can say is WOW.
Should have done this a long time ago.
You should go for this beast of a monitor. The ROG Swift PG65UQ Big Format Gaming Display- 65” 4K UHD with HDR:
https://rog.asus.com/monitors/above-34-inches/rog-swift-pg65uq-model/
Believe me, I was looking into to it. But I mostly play first shooter games on a fast 170hz monitor(XG279Q). I just wanted 4K for the sim and didn’t want to dish out too much cash just for that. So I think I got best of both worlds right now. Or at least close to it. But yeah, it is a beast of a monitor. Maybe when the price drops 
I am running a 50" Samsung 4k UHD Smart TV in 4K
Windows in 4K
MSFS and everything else in 4K
I have been running this combo with an EVGA 1080 Ti FTW 3 11 GiB. for a couple years. X_Plane, DCS, MSFS.
I lower any settings I have to but I won’t give up the 4K.
The difference in the ease of reading guages in 4K is worth whatever else needs to be changed to make it work.
I tried it originally when I bought it at 1080p on the 50" 4K.
Even at that, the guages were far more readable than 1080p on a quality 1080 monitor or a 58" 1080p machine.
The is no way one can go back after using a large 4K screen.
I got my eye doctor to give me a prescription for some readers that focusses at 60 inches (5 ft). Perfect for flight simming.
Stacking 6 documents side by side in 2 rows of 3 and/or many more and being able to read them is nothing to sneeze at either.
I just use an HDMI cable one one end for the TV and a display port on the other end for the GPU. The TV was under $500 Canadian.
This has had daily use over at least 2 years so far with no issues.
Any minor reduction in FPS is more than offset by the far improved ability to actually see things.
The best mod I ever did was to turn off my FPS monitor.
You can expect great performance with your setup.
Running the sim on a 55" 4k HDR television.
It’s pretty great. Set your resolution to 3840 x 2160 and adjust the render settings to the capability of your video card.
Make sure you enable HDR in windows. The sim looks absolutely stunning in HDR. It’s a huge difference compared to SDR.
