That's because you are QUITE affected by marketing.
1: LED is a gimmick and most often a downside.
2: 1200p res is quite low. Even my 17" mid end CRT does more than that comfortably.
3: Advertised Contrast ratios are advertising lies. They matter in no way whatsoever, especially when they are dynamic.
4: Response times are also a marketing lie. They matter in no way whatsoever, since the real numbers are like 10-30ms. (colour to colour)
5: CRTs still beat every LCD in some areas of performance. The GOOD ones provide sharper image, better colours, flat surface, no ghosting, no input lag, and refresh rates above 120hz, like mine does 170hz. Higher resolutions per size. Because of this monitor , I rarely use my side monitors (LCD) anymore because they look like crap in comparison.
6: CRTs are better for fast paced gaming, due to a number of features I am too lazy to list, but will do if you ask me to.
If you have allowed yourself to believe that CRTs are worse just because they are older, I feel sorry for you. You have obviously never seen a good one.
