Open BIOS without going into Windows???? since when can you access the BIOS from Windows? you can't do that!
You need to press and HOLD ESC then power on your laptop, then when you get the boot options, choose ENTER SETUP to access the BIOS.
Do not change any settings if you don't know what you're doing!
To find your screen model
Use
HWiNFO64 then click on the monitor tab to see what model is your screen exactly, then google that model to get the full specs and see if it's IPS or not. Here's mine which is IPS:
