White colours way to bright

@SimCela1  Screens look dimmer as the viewing angle becomes more indirect, which is what you're doing when you tilt it away from you.  It sounds like your screen is just a little too bright or perhaps not calibrated properly.  Does the issue show up in both fullscreen and windowed modes?  Please test if you haven't already.

Your laptop manufacturer may also offer a calibration tool for screens, which you could use to set whites to the brightness you prefer.

Thank you for the reply! It's just as bright for both windowed modes as it is in fullscreen. I've tried using the calibration tool available in the laptop settings, but everthing looks good there! Could there be other ways to do a calibration? You mentioned some laptop manufacturers offer a calibration tool, could that be a different one to the "built in" one? 

@SimCela1  The built-in tool is usually the manufacturer option; the only question is whether it's installed already or you have to download it.  Out of curiosity, what brightness setting are you using on your laptop?  Please also run a dxdiag and attach it to a post.

I went into the calibrating tool and changed some things and it improved the brightness a little, however I still have the problem. Not sure how I find out what brightness settings I'm using though... sorry I am incredibly bad at these things.

I attached a dxdiag file and even though I don't understand much from it, I hope it'll be usefull for you :D 

@SimCela1  I meant the brightness of your screen as you'd adjust it yourself with one of the function keys.  It's possible that your particular screen just starts to look a bit bleached under certain circumstances, and dialing back the brightness, say one or two clicks out of 16, would help.  Your graphics driver looks like it's installed properly and hasn't been throwing errors, at least as far as I can see, and it's the latest driver available from Lenovo for your laptop.  So while you could clean uninstall and reinstall the driver, there's no indication that you need to do that.

You could also try each in-game lighting setting separately, just to see whether one works better than others.  It might be that the lowest settings look not only worse but excessively bright, as in, there's not enough nuance in bright lighting.

Another thing that might help is contacting Lenovo support.  A tech who's worked with laptops like yours could have a better idea of exactly which settings to experiment with, where I can only guess and make random suggestions.  If you go that route, start here:

Enter your serial number and choose the callback option if you can.  Ideally, someone who can access your user manual will walk you through the steps you need to take.
