As one of my last monitors before LCDs took over, I had a 21-inch Sun, and boy was that sucker heavy (>30 kgs (>65 lbs)):

that looks a heck of a lot like a rebranded Trinitron. (I bought a super nice Sony Trinitron from BestBuy in fall 1994 to get a better screen for a second hand Sparcstation 1+ i had.)

Yeah the 21" sun monitors we had in school were trinitron. I remember they were heavy for a 21" monitor (shielding?) and the degaussing on startup would induct into an adjacent monitor. (I was a sysadmin for a Sun heavy CS department in the 90's.)

I'm pretty sure Trinitrons are always heavier than other monitors of equivalent size because of the aperture grill design. It let's more light pass through, making them brighter, but boy do they get stupid heavy as the size increases.

Yes, the aperture grille (hundreds of wires and a metal frame holding them in tension) is itself heavier than a traditional shadow mask.

However, aperture grilles also use differently-shaped glass from shadow masks. The screens are only curved horizontally like a cylinder rather than on both axes like a sphere. This requires thicker, heavier glass to hold the vacuum.

Later flat-glass shadow-mask tubes were much closer in weight to flat Trinitrons.
