Accurately determine the selected screen resolution

[Hottage-sylvanas (Hottage)]

I am currently trying to write an addon which switching my Edit Mode profile depending on the screen size (as my Steam Deck has more than one depending on if I use the built in or external screen).

However whenever I use the following code (even with 100% UI and render scale):

local width = math.floor(GetScreenWidth())
local height = math.floor(GetScreenHeight())
local uiScale = 100

if GetCVar("useUiScale") == "1" then
   uiScale = math.floor(UIParent:GetEffectiveScale() * 100)
end

print (width .. "x" .. height .. " " .. uiScale .. "%")

2560x1440 native returns “2133x1200 100%”.

My plan is to have it match resolution by name either strictly “2560x1440” or losely “1440p” and the actual profile selection already works, but it is kinda counter intuitive to need to create a profile “1200p” for use on a 1440p display.

Can anyone assist?

Managed to resolve this with some help from the guys on Discord.

The solution was to instead use:

local width, height = GetPhysicalScreenSize()

This returns the true display size as set in the graphics menu, my first addon is complete!
