Our Verdict

LG 27UK650-W

Lenovo Q27q-10

The LG 27UK650-W is much better than the Lenovo Q27q-10. The higher native resolution on the LG results in much sharper text, making it a better choice for office use. Despite the lower native refresh rate, the LG has a much faster response time, making it a better choice for gaming as well. On the other hand, the Lenovo has better reflection handling, so it might be a slightly better choice for users in a bright office setting.
