Uncalibrated – Maximum Backlight Level
The SUW49DA is the second 5120 x 1440 resolution monitor we’ve reviewed, so the AOC Agon AG493UCX is included here for comparison, along with an array of 34-inch and one 35-inch ultrawides. They are the Cooler Master GM34-CW, Viotek GNV34DBE, AOC CU34G2X and ViewSonic Elite XG350R-C.
Ultrawide monitors don’t have to be quite as bright as their 16:9 counterparts to provide enough output. That said, the Viotek AG493UCX is an extreme overachiever. It could light up a small town when the backlight is maxed. The SUW49DA doesn’t quite hit its 400-nit spec, but at 360 nits, there is more than enough output for satisfying gameplay or any other task.
Black levels are about average for a VA panel, which results in a respectable 2,599.6:1 static contrast score. The AOC manages to eke a little more dynamic range, but any of these monitors will deliver better blacks and a deeper image than an IPS or TN display.
After Calibration to 200 nits
Calibration (see our recommended settings) gave us a nice gain in dynamic range (2,839:1 versus 2,600:1), thanks to changes we made to gamma and the contrast slider. We also saw an improvement in color saturation.
Our sample monitor had solid screen uniformity and a properly fitted grid polarizer, so intra-image contrast is nearly the same as the static value. That’s excellent performance, especially given the Viotek’s price, which is lower than other 32:9 screens.
