Looking for some advice please, 

I tried using my oldish 42 inch HD tv for my main monitor for FSX. While the size compared to my 24 inch real monitor was nice the level of detail is utterly abysmal, so bad that without zooming in you can't read any of the PFD. Has anyone on tired FSX on a 4k TV, if so what was the experience like? I fancy upgrading but I don't want to fork out unless I know its going to be worth it. 

Thanks for any advice. 

Many 4K 'TVs' are designed to function as computer monitors and also allow you to put them into modes which minimize input lag so they're decent for gaming.

I am curious what brand of HD TV you tried? I have two Sony Bravias which when hooked up directly via HDMI to my computer, downscale the image to something awful like 640X480 - completely unusable. I am convinced it's some sort of video copy protection that Sony has lurking in their firmware (though I've never been able to verify this). However, when I use an intermediary to plug my PC HDMI into, in particular, a sound bar, then plug that device into the Sony TV, it works quite well.

bgyuk,

I cannot help you here, but I do have a reasonably similar problem.  I have a 60inch 1080p LED tv as my main screen. I use this for my virtual cockpit. I can however, read my dials albeit not incredibly clearly. I too would like to upgrade to 4k but I think I would run into the same problem that I assume you MAY run into. That would be a fairly dramatic loss of FPS. and for you, maybe some OOMs. I am running FS2004 with 6 monitors but all are 1080 or similar. Whilst my frame rates are good to excellent most of the time (I do get down to about 20FPS at heavy airports) I believe going to 4k may well drop the bottom out of it.

In that vein I would love to know if the 4k as opposed to 1080p 

is really going to have any dramatic effect on our FPS and/or smoothness

Many use a 4k TV, including myself. See the hardware forum.

It's great btw, everything is so crisp and sharp, including gauges, you almost don't even need to use anti-aliasing.

I use a samsung 8500 65 inch tv as a PC monitor and for P3D 4.1.

It looks wonderful, and I really enjoy the combination of this size and 4k resolution.

I use an old 2600k processor overclocked to 4.2 Ghz and a 1080Ti with most settings set pretty high.

To be fair I don´t use any special airport scenery as I don´t really care about that but I do use orbx general

enhancements. I set the fps to 30, vsync on and it holds in most situations on the pmdg 747.

Amazing how the 2600k holds up, it´s still going strong for me.

Using a 4K TV and its made a HUGE difference in my simming experience. 

A 4K TV is a great option as a monitor for simming--I use a dedicated 55 inch Samsung JS8500 here for P3D (v3.4 and v4.1)...but it's not the best solution for FSX, ahd here's why:

The catch with FSX is that the CPU is doing much (most) of the rendering work rather than the GPU, so it's going to hit the frame rate pretty hard having to compose all those huge 4K frames.  Running in DX10 "preview" with DX10 Fixer will help, but only to a point.  I have run FSX on my TV by turning scaling off and dialing the resolution down to something less that the full 3840x2160 (e.g. 3440 x 1440) and accepted the border around the smaller (but still fairly large) screen area.  That works to get my MD-11 flying in FSX on occasion, but most of my flying is in P3D where DX11 and powerful graphics processor(s) can deal with composing and antialiasing 8 megapixel video frames.

If I were going to run FSX as my primary sim, I'd probably go with a 21:9 monitor like the Dell UW3415 rather than a 4K TV...the screen area is still pretty large, but the pixel count is less than 60% of the 4K image.

So use caution, FSX is going to struggle at 4K unless you have a cutting edge CPU and dial some settings back.
