I tested it on my 14 inch laptop and it displays just fine.Q-Dr is good if your laptop is at least 15 inch size. Otherwise the text will be too small for the smaller size laptops when displaying 4 screens. For me 2 screens side-by-side is just nice for a 15 inch laptop for legible reading.
What size laptop will you be getting? I'm planning to get a 15 inch laptop after the Redstone 3 release so Q-Dir is a good addition
Can you read the text legibly when in 4-screen mode?I tested it on my 14 inch laptop and it displays just fine.
