I'm asking this question because I had an outdoor event we did and it was hard to see the screen on my main laptop because of the sun. It was difficult to see the screen at this outdoor event we did. So please help me. I didn't want to order something that may or may not work. What would any of you suggest? The laptop is an old Lenovo I got for a great price a few years back and it's working great. No issues so far.
