jaggies and weird font scaling with certain monitor sizes

[skypickle]

current display settings:

monitor 1: 3840x1600

monitor 2: 3840x1600

monitor 3: 1920x1080

monitor4: 1920x1080

main monitor is #2.

Following this guide

 

I set up my MFCDs to show on monitor 3.

I then set my kneeboard to open up on monitor 4 with this:

In D:\DCS World OpenBeta\Scripts\Aircrafts\_Common\Cockpit

the ViewportHandling.lua has

    

dedicated_viewport           = {2000,1600,800,1060}

in the first function, function update_screenspace_diplacement(aspect,is_left,zoom_value)

(yes, in the properly installed game, 'displacement' is mispelled)

 

 

In DCS settings,when I set monitor size to 3840x2680, aspect  is 1.4328358208955 

everything renders fine. The graphics are smooth, the fonts are legible. This monitor setup uses the entirety of 3 monitors. But I want to steal some screenspace from monitor 1 as well (for the SRS window, etc)

 

I change the settings in DCS to

5760 x 2680  aspect 2.1492537313433 , I get jaggies in the game graphics + in the fonts of the GUI. The MFCDs still show up where they're supposed to and the kneeboard shows up n the same place. All I did was to steal some screenspace from monitor 2 for the game (for SRS messages,etc)

 

I also tried 5760   x   4020  aspect 1.4328358208955

but I still get jaggies in the graphics in game and the fonts displayed in the GUI

Is it not possible to use PART of a secondary screen?
Must the pixel count of entire screens be included in the DCS graphics settings?

Have you tried setting the resolution to something like

4340x2680, you can type the resolution into the settings box in DCS game menu, you don't have to choose from the drop down list.

aspect, 1.619

that should give you 500 pixels of your monitor 1, I doubt you'll be able to run in fullscreen with that

You are correct, checking the fullscreen checkbox just squashes the whole screen buffer (whatever pixels are set in the settings) onto the main monitor-terrible distortion.

 

Using 4340x2680 is just like the issue I described above-jagged in game graphics as well as jagged fonts in the GUI.

I also tried 4288x2680 (an exact 16:10) aspect and still get the irregularities. I noticed that all these resolutions are for a screen size for which a monitor is lacking (there is no monitor for the bottom right part of the screen buffer)

So, I also tried 5200x1600 (aspect exactly 3.25, using entire main monitor and part of the monitor to the right), I still get the irregularities. 

 

I was beginning to think that DCS gets confused when you ask it to use a screen resolution whose pixel count neglects part of a monitor.

So I tried 3840 x 2200 (basically only using part of the bottom two monitors) The image was perfect though. No font irregularity in the GUI, no jaggies in the game. So I then tried 7680x1600, still have the irregularities.

Then I tried 7680x1600 but set DCS to one screen. Still have the irregularities , but DCS used two screens anyway.This is the lua file for 1 screen - as simple as it gets
 

  = function(p) return p; end;
name = _('1 Screen');
Description = 'One monitor configuration'
Viewports =
{
     Center =
     {
          x = 0;
          y = 0;
          width = screen.width;
          height = screen.height;
          viewDx = 0;
          viewDy = 0;
          aspect = screen.aspect;
     }
}
GU_MAIN_VIEWPORT = Viewports.Center

That's why dcs used both screens- because screen width uses ALL available pixels (which is two screens). but it does not explain why the rendering is poor.

You can run it in full screen mode, when it starts and it's all squashed, just left click somewhere on your second monitor and DCS should resize. Or try Alt+Enter twice, or Alt-Tab out of DCS and back in again.

I have seen "Some issues with exporting the FA-18 MFCDs are reported to be because the vertical resolution exceeds 1440 pixels." in the forums

Depending on the Max resolution your graphics can take, you could try rea-arranging your displays in windows.
