Sharpness of the image of a CRT depends on the quality of the CRT. One reason why CRT failed is because people were going to stores and went "Give me the cheapest computer monitor", so they get a terrible hard to read text screen, at 60Hz, that flickers and cause headache. In was in a time where the average computer users did not understand the concept of "you get what you paid for". A good CRT will give you a very sharp image, and no flickering or headache. CRT sizes exists in 32inch and even higher, I think I even saw 42inch CRT screen if I am not mistaken. Back in the old days, people were buying 27inch size screens, and that was considered large. 32inch was getting over the top. Something, thus, that you must remember, is that LCD screens are in widescreen. A 19inch LCD is much smaller in height then my 17inch CRT computer monitor.
