The 1084 and its variants (1084S, 1084S-P, 1084-P, 1084S-P2, 1084-D, 1084S-D, and 2080) are all 15.75 kHz monitors. They do not handle AGA "double" screenmodes, nor will they display the deinterlaced output from the A2320 Amber board or the motherboard deinterlaced output on an A3000. However, they will show all normal 15.75 kHz displays, and many (most? all?) of the 1084 versions have a separate input for composite video.
The 1084 is a usually a variation of the Philips CM8833 monitor; the 1084S-D was made by Daewoo (as was the 1084D, probably). The display tubes used in these monitors were made by Orion, Toshiba, Hitachi, and Samsung.
At one time or another, every possible permutation of connectors and video capabilities on the 1084 seems to have been reached, so don't be surprised if your 1084 has some bizarre combination of connectors and specifications.
Common Problems
The 2080 is a long-persistance phosphor, .39 mm dot pitch.
