Summary

Little is known about this monitor but it has appeared in a few Japanese websites and auctions. The supported resolutions were confirmed by a Japanese Buyee auction for the monitor. The weight is also unknown but it has been confirmed to be significantly lighter than the Sony BVM 32" D32 monitor (which makes sense since the tube is not a flat Trinitron).

The brand Chuomusen is known for making test equipment and pattern generators, similar to Shibasoku. It has been speculated that this monitor shares some attributes with the Ikegami HTM-3203 and likely has a Panasonic tube inside, but nothing has been confirmed. If you know someone that owns this monitor please contact me.
