The tent won't help a bunch other then give you some shade. Laptops and keyboard screens leave much to be desired in viewing out doors. I played every Saturday for a farmers market a couple years ago. They changed managers and she didn't like me. She wanted a lady with a guitar. I was getting $150 a gig there for 3 years. I Velcro-ed a painted black cardboard cover over the screen with enough room to read the screen on the arranger and I put the laptop in a cardboard box I spray painted black too. It barely helped. The sun is a %^&%$# on screens.
