I had one of those! Loved the glossy screen on it. I sold it on a few weeks ago actually!
The CX48 is the first monitor I've used since the 20WGX2 that has the same type of glossy panel. I really missed it, and can't believe how relatively terrible the matte or semi gloss finishes I've had on the monitors I've used in between.
I upgraded from the 20WGX2 to a NEC 24WMGX3, a 1920x1200 VA monitor. Good upgrade in terms of real estate and resolution, but didn't look half as good as the 20WGX2. Moved to a 27" BenQ XL2730Z a few years later, TN 1440P 144Hz panel. Washed out colours, horrible matte coating, but was very fast and response.
If you liked the 20WGX2 you'll love the CX48. Imagine just a bigger version, with even deeper blacks, instant response time and 120hz!
