HP U28 4K HDR Monitor
Microsoft Windows 11

My U28 4K HDR monitor has an issue whenever I start it up. Any gradient in colour or shaded area appears very pixelated. This issue is slightly fixed when I go in settings and switch the HDR option on and off. This partially fixes the problem but if i refresh my screen or restart my PC, the issue comes back. The image attached doesn't entire show the extent of the pixelation but regardless, it isn't exactly smooth. I don't know what to do since I've tried replacing the cables, using different ports, trying other desktops, updating both monitor and PC drivers, factory resetting and other things but nothing works. Can someone please help me fix this.  This isn't bad picture quality the screen actually looks like thisThis isn't bad picture quality the screen actually looks like this

Hi @Ubaid_A ,

 

Welcome to the HP Support Community.

 

I'd like to help!

 

Excellent description and a great diagnosis. It is greatly appreciated.           

 

This might require one-on-one interaction to fix the issue as it looks like a hardware issue. 

 

As we have limited support boundaries in the support community as of now. I would request you to contact our HP Support Engineers who should be able to sort this out. HP provides repair or service options as well. Hence I encourage you to contact HP support

Hello there,

I have the exact same problem with HDR sources. Color gradients are terrible.

Could HP support give a solution on this forum ?

Thank you !

Hi,
They messaged me directly simply saying that I might need remote assistance. If you have tried most things then I suggest calling them. They gave me this number:

I've been super busy and haven't had a chance to call but I don't think this issue fixable in all honesty since I have tried everything. Maybe you will have more luck!
