I purchased a Lenovo Thinkpad E580 i7-855u, which came with a 1TB HDD and 8 GB RAM. Upon purchase, I had the seller put in another 8GB RAM and a 512 GB SSD (on which he reinstalled Windows 10 Pro). I have attached some relevant details about the GPU and other details.
The vendor assured me that all additions are compatible.
Now, ever since I bought it, the display has had a bluish tint, which causes me a lot of eyestrain and irritation, making it very difficult to look at the screen for more than a few minutes. I have made sure that Windows is up to date and have updated all drivers. I knew before purchasing that it wouldn't have the best displays (it's only 1366x768), but since my work is mostly confined to Excel and programming, I didn't mind. But the bluish tint and overall quality is so low that I can't even do that. I have tried adjusting brightness, hue, saturation, contrast, etc but to no avail.
I am wondering whether there's something fishy about the details I have attached, and what may be possible causes of the bluish display.
Thank you.
