Does my monitor support 4K

[SHINRA-CORP]

I have had this monitor for over a year now and something about it has baffled me. It is a 1440p monitor yet I'm able to output at 4k.

I know this because a message will pop up on the screen stating the resolution.

Is it a fake/upscaled version?

The best example I have is when I play on my Ps5 and I go to the screen settings. I have the option for 4k resolution. If you select it the Ps5 will enter a screen outputting 4k. It will then display a message saying "if you can see this press X" with a timer ticking down incase you cant see it.

Comes this message from the monitor, Steam, the game or driver?

You might have DSR turned on in nvidia control panel (or AMD if that's what you're using). It's a way of faking a higher monitor resolution so that the game can render at that resolution and then downscale.

Probably not. Connected hardware (PS5, your GPU, etc.) gets the supported resolutions ("source modes") by querying the monitors EDID chip.

If you open Powershell, you should be able to query this list directly by pasting this:

wmic /namespace:\\ROOT\WMI path WmiMonitorListedSupportedSourceModes

If you want more readable output, then paste this instead:

$wmicOutput = wmic /namespace:\\ROOT\WMI path WmiMonitorListedSupportedSourceModes

$wmicOutput | ForEach-Object {
    $fields = $_ -split '\s+'  

    if ($fields[3] -eq 'VideoModeDescriptor') {
        $width  = $fields[7]
        $height = $fields[24]

        "$width x $height"
    }
}

We can usually assume that the highest reported resolution is the native resolution of the monitor.

However, it's not exactly unusual for monitor firmware to be faulty and return incorrect EDID data or no EDID data at all!

It might be worth checking the monitor manufacturer's site for updated firmware... bearing in mind it can only usually be updated if your monitor has a USB port.

Edit to add: Most monitors deal with non-native and non-supported resolutions by scaling the image up or down... usually with bilinear or bicubic algorithms which reduce sharpness.

PS5 sounds like using spectral Super Resolution (PSSR) that monitor from specs only supports 1440p native but can you over drive refresh rate
