Summary
IBM's top of the line monitor in 1999, the P260 was manufactured by Sony and features a 21" flat Trinitron tube. It is based on the CPD-G500. Differences from the original Sony model include an IBM-style case design, redesigned control panel, and a DVI-I jack for the second video input.

Notes
This tube has a fragile Diamondtron / Trinitron anti-glare coating which will be damaged by all common cleaning products including Ammonia-Free products. You should only clean it with water or water mixed with a few drops of dish soap. Use only a soft clean microfiber towel to wipe the screen.
If the screen has missing/discolored parts of the finish, or spots that look like scratches that don't come off, or parts where the mirror finish is missing, the coating has already been permanently damaged and should be removed. You can find instructions for removing and replacing the film here.
Many brands used these coatings including Mitsubishi, Sony, JVC, IBM, and more. Usually if the underlying tube technology is aperture grille-based and the monitor is a higher performance PC monitor, it can be assumed the tube has this fragile coating. The user manual of the monitor will also mention not to use any cleaning products on the screen.

The DVI input jack only uses the analog pins, and is effectively just a second VGA input. It's best used with a DVI-I to DE-15 adapter cable.
The flyback in this model is a valid replacement for the Sony GDM-FW900. Looking at the part numbers they are very similar (NX-4504/J1D4 vs. NX-4502/J1D4) and the schematic shows they have the exact same pinout, and the nearby circuits each pin connects to are close enough to be considered compatible.
Brightness issue
There is a common problem where these monitors are too bright and the OSD controls don't allow you to correct it. In that case you need to use WinDAS to lower the G2 value in the monitor's firmware settings.
