GetDisplayResolution

Get width and height of specified resolution index for display mode. See the options.display.resolution registry node docs for details.

Like all UI functions, this function will only exist if draw is defined before init is called.

This function is not officially documented.

Arguments

1. integer (number): Display mode. 0 is exclusive fullscreen, 1 is windowed, 2 is borderless windowed. Truncated if has fractional component.
2. integer (number): Which resolution to use. Zero indexed. Use GetDisplayResolutionCount to know how many options there are. Truncated if has fractional component. Clamped if out of bounds.

Return values

1. integer (number): Width in pixels.
2. integer (number): Height in pixels.

Example usage

function init()
	mode = 0
	resolution = 0
end
local function button(label)
	UiPush()
		UiColor(0.75, 0.875, 1)
		local pressed = UiTextButton(label)
	UiPop()
	UiTranslate(0, UiFontHeight())
	return pressed
end
function draw()
	UiFont("regular.ttf", 32)
	UiTranslate(0, UiFontHeight())
	if button("0 (Exclusive fullscreen)") then
		mode = 0
	end
	if button("1 (Windowed)") then
		mode = 1
	end
	if button("2 (Borderless windowed)") then
		mode = 2
	end
	UiText(string.format("Mode: %d", mode), true)
	for i=0, GetDisplayResolutionCount(mode)-1 do
		local w, h = GetDisplayResolution(mode, i)
		if button(string.format("%d (%dx%d)", i, w, h)) then
			resolution = i
		end
	end
	UiText(string.format("Resolution: %d (%dx%d)", resolution, GetDisplayResolution(mode, resolution)), true)
end
