Our Verdict

Samsung Space SR75

LG UltraFine 4k

Overall, the LG UltraFine 4k is a bit better than the Samsung Space SR75, but the SR75 is much better for gaming. The UltraFine has a higher native resolution and much better viewing angles. The SR75 has better contrast, so it's a better choice for a dark room, and it has much better gaming performance. The SR75 has a higher refresh rate, it supports AMD's FreeSync variable refresh rate technology, and it has much lower input lag, for a more responsive gaming experience.
