Our Verdict

Dell U3818DW

Samsung C49RG9/CRG9

The Dell U3818DW and the Samsung CRG9 are similar, but due to the differences in panel technology, they each have their advantages and disadvantages. The U3818DW uses an IPS panel, which delivers wider viewing angles, and the Dell has better ergonomics. The CRG9 has a much larger, higher resolution screen, and is a much better gaming monitor. The CRG9 supports HDR, has a faster refresh rate, and much better motion handling.
