New QFHD (4K) UHDTV Question.


Recommended Posts

Just reading about the new QFHD (4K) display where resolution is a stunning 4096 pixels and I am wondering if it would be worth investing in a display.  Currently I am using a 40" Samsung 6000 series and while I do not mind how the sim is displayed I would be happy to improve picture quality. 

 

So my question is; would FSX recognize the 4K resolution capability of the display and render graphics any higher than 1080 resolution or would it be a waste of time?

What resolution and size is your display and what do you achieve with downsampling ?  Did you enter the resolution in the FSX.cfg?

 

**EDIT**

 

I have read a little on downsampling, very interesting, I'll give it a try and see how it goes.  Thanks for providing the information.

My monitor is 21.5" with a resolution of 1920x1080. With downsampling I can get the same effect with OGSSAA, but you have more control over what resolution you'll supersample from. For example, with a resolution of 2880x1620, I am downsampling from a resolution 1.5 times higher than my monitor's native, which gives me an effect similar to 2x OGSSAA (double the amount of pixels). For 2x2 OGSSAA, you'll have to downsample from 3840x2160.

 

Also I didn't have to enter the resolution in the FSX.cfg, all I did was pick the resolution from the graphics settings.

Very interesting, I'll give it a try and see what happens.  Still wondering about my original question though, would a 4K display be better than an HD @ 1080 resolution?  Let's see if anyone else has some information.

Higher pixel count is always better visually as there is more image information so more visual detail.  If "better" means performance then the answer is no ... you'll see a significant drop in performance over 1920 x 1080.

 

Equation is:

1920 x 1080 =  2,073,600 pixels

2560 x 1600 = 4,096,000 pixels

3 X 1080p monitors (5760 x 1080) = 6,220,800 pixels

3840 x 2160 = 8,294,400 pixels

4096 x 3072 = 12,582,912 pixels

 

So about 6X more pixel processing in 4096p ... so if you get 60 fps at 1080p then expect about 10-15 fps at 4096p.  

 

If your questions is how well will a 4096p display show at 1080p source then that will depend on the monitor and how well it up samples.  My Sony XBR 3840 x 2160 displays 1080p, 1600p as good as (if not better) than monitors that show those native resolutions ... "I think" this is what you are trying to determine?

 

EDIT: Also be aware the video card can do scaling (aspect, full screen, none) ... typically it's better to let the display do the scaling (if capable).

 

Cheers, Rob.

Currently my 40" Samsung display is running at 1920 x 1080 so the same image is being displayed as it was when I was plugged into a 27" display at 1080p only spread out to the larger 40" display which can be pixelated to some degree.

 

Does P3D recognize the Sony XBR 3840 x 2160 resolution in the settings menu?  I'm trying to figure out if FSX/P3D reads graphic capability so when you plug into a HD vs 4K display will the sim recognize the higher resolution?

I tried setting my desktop resolution to 3840 x 2160 via nvidia - custom resolution and then set FSX to the resolution and it definitely sharpened up the textures.  After quitting FSX my display went black and I had to revert back to 1920 x 1080 after I rebooted.  I will look into why the desktop went black although I am sure the Samsung 6000 series can handle the higher resolution.

My understanding is that increasing your monitor resolution would increase the amount of terrain or panel that would be visible, not improve the image quality as the resolution of the image textures is set by the developers. Is this incorrect?

 

I have three 1280 x1024 monitors set up to give me a 3840 x 1024 display. The image on the center display is the exact same image I had when I only had one monitor hooked up. What I love about the 3 monitors is the additional panel area and outside view that is available horizontally. I am interested in these HD monitors as I was thinking that something with a 3840 x 2160 display would provide additional view of the cockpit panel vertically so i wouldn't have to scroll up and down to see all the instruments. Someone please correct me if this is wrong.

 

I have been doing some testing on the single montior vs. triple monitor performance and I can tell you that tripling the pixels has resulted in about 25% drop in FPS in both DX9 and DX10, for example 40 FPS to 30 FPS.  This is as long as the video card usage is not at its limit. With my 3 low resolution monitors, most sliders right and 8X SGSS, I can bring my 780GTX to it knees in DX10. For reasons I do not know, the video card usage does not reach its usage limit with the same settings in DX9. So I am expecting that I will have to live with lower display settings if I get a 3840 x 2160 display and/or  get a better video card and perhaps CPU. I currently have a 3770k at 4.5 ghz.

I am sure the Samsung 6000 series can handle the higher resolution.

 

I just searched for the Samsung 6000 specs and it support 1080p, nothing higher than that.

It'll depend on where the instruments you want to look at are and your zoom level and where you set your eye point ... I map the eye point movement keys to a 4 way button on my Yoke so I can get the best position (when I'm not using TrackIR5).

 

Cheers, Rob.

Thanks for the response Rob. I don't want to hijack Hussar's thread anymore than I already have so I will start a new thread on eye point settings and  obtaining a larger view of the panel without TrackIR.

If you have a specific aircraft in mind, let me know ... if I have it, I'll test it out for you and make a quick video so you can see if it meets your needs.

 

Cheers, Rob.
