My head hurts.
At my brother's advice, I went with the GW2280 instead of the GW2270. But they should share the same strengths and... pains.
Extremely bright at 0% brightness and 0% contrast. Rapid migraine trigger. Can't tell if screen slowly pulsing or just my migraine doing that.
Comes with D-Sub cable, had to borrow other cables. Currently using HDMI to DVI cable.
Unless I've missed some trick, I'd rate this 0/5.
