Acer Nitro XV272U Pbmiiprzx monitor brightness too dim without Windows HDR enabled

rmendez011

I have an Acer Nitro XV272U Pbmiiprzx monitor (the Pbmiiprzx is the important part), the screen is too dim if I don't enable HDR in Windows settings and max the HDR brightness.

If I do enable Windows HDR and max out the HDR brightness, the screen reaches the advertised brightness, this is fine for my main pc with a 2060 Super, however, HDR brightness is nonexistent on macOS devices, same with macOS devices with older GPUs, same with older Windows PCs with older HDMI/DP ports that don't support HDR.

My monitor has 4 USB A ports, which means I should technically be able to update the firmware as I've seen with other XV272U monitors, however, my question is where can I get that firmware for my monitor? I have the updated firmware {XV272U KV_XB273UNV_VG272UV_XV272UV_XB323QUNV_XV322QUKV_Monitor_USB_Upgrade_Tool) for said devices, however, it doesn't work on my device, the program doesn't detect my monitor, I have tried at least 5 different computers, same issue.

The service menu shows that I have a XV272U P model, a RTD2797UP chip, a INX M270KCJ K7E panel, and the monitor is running 0.04 firmware version, not sure if this helps.

I understand you are using the monitor Acer Nitro XV272U

Please use the control buttons on the monitor and check whether you can do the factory settings. After the factory settings check whether the brightness is working properly.

Go to support.acer.com 

chose your country 

type snid or chose your model 

go to drivers  and check the latest driver both for your computer and monitor. If found try to download and install it.
