Glass manufacturers are significantly scaling back on 4:3 ratio glass that it is very difficult to source in volume. Note that 95% of all the glass in the world for both LCD TVs and computer panel are made by 5 companies ( 3 Taiwanese and 2 Korean) TVs are sourced and sold in billions, computer screen in 10s of million – I’m sure you have not seen a standard ratio TV screen in a long time.
