I have another one of these exact chromebooks. So I bought another to keep in my truck. The Resolution was very messed up. 280-360 at best. What made me realize it as I had bothered out and was moving files from one to the other. And the letters were not as crisp looking on my new one. The blacks were hugely different. I turned the brightness all the way up and all the way down to. Tried the contrast settings same thing the new one was funky looking. I'm trying one last thing before I raise hell with Amazon or acer one. Don't you just hate getting semi- big ticket item and it comes out the box messed up.....
