Well, we are discussing a CRT TV that was $40k new a life time ago, so perhaps the fact that it costs $599 to get a 480Hz OLED today is not a consideration. To the point though: it is a fallacy to believe that CRTs could arbitrarily shape their resolution. While the input signal could cover a wide range of possible resolutions and refresh rates depending on the bandwidth supported, the existence of apperture grilles or shadow masks imposed a fixed digital reality that limited the maximum possible resolution to much lower values than the typical 4k panels that we have today. The "pixels" didn't become larger on lower resolutions: they just covered more dots on the mask. We can get much better results today with scaling than we ever could on CRTs, as awesome a technology as they were 40 years ago.
