Our Verdict
Samsung C49HG90/CHG90
Dell U3818DW
The Dell U3818DW is a bit better than the Samsung C49HG90/CHG90, unless you want the largest screen available and watch in a dark room. The U3818DW has much better viewing angles, which is extremely important in a monitor this size. Overall, motion looks better on the CHG90 thanks to the much faster refresh rate, but the CHG90 has PWM flicker, whereas the U3818DW is flicker-free.
