[SOLVED] 4K Monitor Resolution

[akiro525]

Hello,

i have 2 Asus VP28UQG 4K monitors hooked up to a Gigabyte GeForce GTX 1080Ti Gaming OC BLACK via display port 1 and 2. i have my resolution set to 3840x2160 in windows but whenever i check my resolution online it keeps saying 2560x1440. i tried to do my own research to why that is and why the resolutions are not matching up but just getting myself more confused.
i did find a site that said my resolution is 3840x2160 and the browser Browser Width/Height is 2560x1440 but i didn't realize that was a thing.
am i doing something wrong or do i need to enable 4k somehow?

Thanks i advance.

If you have Windows scaling enabled then it will interfere with resolution detection websites. Sounds like yours is set to 150%.

yes you are correct,
very embarrassing because i did set it to 100% before checking as well but just realized i only did it for my 2nd monitor and not my main.
thanks for your help.
