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
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.
This monitor includes digital convergence controls, accessible through the OSD menu.
Brightness & Color Issues
PC Monitors made by Sony often have drifted out of calibration. This can result in poor color balance, excessive brightness, or other issues. These monitors often have an extremely bright picture, sometimes with a green tint. This cannot always be corrected with the OSD controls, and the monitor's firmware settings must be adjusted using WinDAS, Sony's proprietary calibration software.
This tube has a fragile anti-glare coating which will be damaged by all common cleaning products including Ammonia-Free products. You should only clean it with distilled water or distilled water mixed with a few drops of dish soap. Use only a soft clean microfiber towel to wipe the screen. I reccomend buying a spray bottle to mist the screen with the water or dish soap solution.
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.
