To compare the Dough Spectrum Glossy’s performance, I’ve rounded up the Spectrum Matte, Corsair 32UHD144, Sony U27M90, HP Omen 27u and Dell G3223Q. All are 4K 144 Hz monitors with wide gamuts and HDR.
Pixel Response and Input Lag

The Spectrum Glossy responds at the same speed as any other 144 Hz screen, 7ms, which gives it decent, if not life-changing, motion blur characteristics. The differences between monitors running at the same speed come down to the overdrive, and there, the Dough monitors have a distinct advantage.
Both Dough displays are a tad slower in overall lag than the competition. I don’t notice a two or three-millisecond difference during gameplay, but more skilled players might. However, if you’re that good, you might be better served running a lower resolution at a higher frame rate. The Spectrum monitors are as good as it gets for motion resolution in 4K.
Viewing Angles
The glossy coating doesn’t affect viewing angles. The Spectrum, like most IPS panels, goes green at 45 degrees horizontal. However, the drop in brightness is only around 10%, which is better than most. The top view is also better than I typically see. Though there is an obvious blue tint, detail isn’t as thoroughly washed out. Brightness is down around 40%.
Screen Uniformity

My Spectrum Glossy sample wasn’t quite as tight as the matte panel I reviewed last year. But at 11.06% deviation, the issues are minor. I could see a slight glow in the lower left corner, but the rest of the screen was visually perfect. There were no color aberrations or variations in brighter patterns. There was no visible problem in actual content.
