Well, when i needed to reinstall the SO, it was because i had two SO (linux and windows) and i wanted to remove the GRUB and idk why, windows started to analyze the hard disk (ssd), so i let it until next day (24h) and still was at the same percentage, so i decided to reinstall windows but maintaining my files, and since then i seen a worse laptop screen colour.

I tried with an external monitor (tv) and the colour was in 8 bits, so since i don't have warranty in my laptop, i will manually check the screen buses

I hope this can help and sorry for not answering before

Hello Blumoop, 

Thank you for responding back to us. I just want to confirm, when you tried an external monitor, the color issue disappeared is that correct? By the way, what display port configuration do you use in your system? You also mention about using Linux. When using Linux, is the same display appearing on your laptop as well? I will be waiting for your reply.

Well, thanks for asking, the external monitor was an hdmi tv, and the linux screen mode i don't remember because i uninstalled linux after some days of reinstalling, but i think that worked good with no problem

About my internal display its an full hd monitor lcd with led backlight.

I think that this problem it's a driver thing, also thanks for worrying about my problem

And sorry again for not answering

Hello Blumoop, 

Thank you for responding back to us. I have here some troubleshooting steps that you can take. First, I did noticed you are using a different driver version of your graphics. I did some research for you and found out that the latest driver available for your laptop is 31.0.101.4502 Rev.B. Kindly please install this in your system and check if the same issue still occur. 

Kindly please make sure as well that there are no pending updates on your Windows Operating system. Finally, please update your BIOS to the latest F.32 Rev.A version 

Let us know if this works. I will be waiting for your reply.
