Intel HD Chip Resolution Bug

[MaxAigner]

Hello People,

 

I have a question about one Intel Card Related Issue.

 

Summary:

When I Start a Leadwerks Program, the Fullscreen is bigger than the hardware-screen itself, so about 30% of the Leadwerks Content is outside of the hardware screen (see attached file)

 

Download this example Code - change the resolutionx and resolutiony in the main.lua

( note the ball is not in center for big resolutions - you can see the too big fullscreen when you have a second screen on the right)

Code:

import "LEAddon.lua"

Steamworks:Initialize()

--Set the application title
title="AMES Präsentation"

-- notfalls über GetProperty einfach die commandline params "resx rexy" holen -> mit Purebasic dann einfach einen Launcher machen.
resolution = Vec2(0)
resolution = System:GetGraphicsMode(System:CountGraphicsModes()-1)
countmodes = System:CountGraphicsModes()
erg = Vec2(0)

resolution.x = System:GetProperty("resx" , 1024) -- the resolution of the notebook is 1920
resolution.y = System:GetProperty("resy" , 768) -- resy is here: 1080

--Create a window
local windowstyle = window.Titlebar
windowstyle=windowstyle+window.FullScreen
window=Window:Create(title,0,0,resolution.x , resolution.y,windowstyle)
window:HideMouse()

--Create the graphics context
context=Context:Create(window,0)
if context==nil then return end

 

How can I fix this Issue of a too big screen...?

So your monitor is 1920x1080 native resolution and you're creating a 1024x768 fullscreen window? On my card that works, but it's ugly. You want to create a window with the same aspect ratio, like 1920x1080, 1600x900, 1280x720, etc.

nono I am creating a 1920x1080 fullscreen window on a 1920x1080 native resolution screen

[MaxAigner]

first I looped through the GetGraphicsMode() Modes with a and just picked the one that has the same aspect ratio

it was something like this:

resolution = Vec2(0)
countmodes = System:CountGraphicsModes() 
for i = 0 , countmodes -1, 1 do
  vec = System:GetGraphicsMode(i)
  if math.floor(1024/768) == math.floor(vec.x/vec.y) then
     resolution.x = vec.x
     resolution.y = vec.y
  end
end

(it had the same Issue of too big Fullscreens)

 

NOW I am using an External Launcher But still I have that Issue but ONLY on three of my INTEL chips - not on two tested Nvidia devices....

 

DOWNLOAD Example (works with ALL Leadwerks fullscreen projects)

You're using two monitors and it appears in between them?

[MaxAigner]

I have tested it on two computers with a HD 4000 from Intel:

1. Intelchip PLUS Monitor
   
2. on my surface there is an Intel Chip and no monitor !
   

both have the oversized Leadwerks screen.

 

on GTX 980 there it Works completely fine (no issue!) ! with the same code (the same exe file)

 

the error comes only on high or HD resolutions like 2160x1440 or 1920x1080

Do you have a notebook to test it with a high resolution?

[Josh]

I do not have a laptop with an Intel chip but I tested with a discrete Nvidia GPU and with Intel HD graphics. I ran the "resolutiontest" application with both hardware setups, and got the same results. I did not change any code.

[MaxAigner]

Hm that is awkward - anyway I have an Idea -

Probably it is because of the touchpanel that both my "infected" computers have!

probably you can try out a surface pro 3 -> maybe there are some issues because of the higher scaled touchpanel or something

what do you think?

 

yours
