Using laptop outside

We're having a sunny day here today with very comfortable temperatures and a slight breeze so I'd like to use my laptop outside on the patio. The problem is that my screen is VERY reflective and when I try to use the computer, there are so many reflections from my surroundings that I can't make out what's on the screen very well at all - and that's sitting in full shade. It's even worse out in the full sun.

Is there anything I can do to make my laptop usable outside? For what it's worth, I have the same issue trying to use my cell outdoors; it's so hard to read that I have to step inside to have any real prospect of reading it.

It's a Dell 5559 running Window 10 Home, build 1809.

There seem to be some products available although I have zero experience of these:

Fwiw, I have a Dell Vostro laptop and I specified it to have a matte screen as standard. When I first unboxed it I thought I'd made a mistake because it lacks that glossy hi-tech showroom appeal look, however in use its been absolutely fantastic.

This is from the web but I'd say its a true representation of how things look when comparing the difference between regular glossy and matte:

Thank you, Mooly!

I suppose I should have realized there would be anti-glare filters that can be applied to laptop screens.

Now I just have to compare the various products and pick the one that seems best.

Thanks again!

You're welcome and good luck with whatever you try
