Our Verdict
Gigabyte G27Q
Lenovo D27-30
The Gigabyte G27Q is much better than the Lenovo D27-30. The Gigabyte has a much faster refresh rate, a higher resolution screen, and better viewing angles. The Gigabyte also has much better ergonomics and a significantly faster response time. On the other hand, the Lenovo has better contrast, and it looks better in a completely dark room.
