Our Verdict

Samsung CF398

Acer XF251Q Bmiirx

The Acer XF251Q Bmiirx is a 25" TN monitor, whereas the Samsung CF398 is a VA monitor. The XF251Q has better motion handling, thanks to a faster response time. The XF251Q is a bit brighter, but the CF398 has much better native contrast, so it looks better in a dark room.
