Our Verdict
Dell U2718Q
Samsung Space SR75
The Dell U2718Q is a bit better than the Samsung Space SR75 for most uses, but the SR75 is a bit better for gaming. The U2718Q has a much higher native resolution, it supports HDR, and it has much better viewing angles. The U2718Q also has better ergonomics, despite the unique design of the Space SR75. The SR75 is a bit better for gaming, though, as it has a much faster refresh rate, lower input lag, and it supports FreeSync variable refresh rate technology.
