A K7000 series is a standard resolution only monitor (ie: 15kHz). You can verify this by looking on or around the chassis for a sticker that has the specific model number like K7125 or something. I've also seen labels on the metal frame at the top of the tube. It is NOT the model of the tube itself. Those are made by a variety of manufacturers, much in the same way the brand name of a capacitor on the board is not the model of the entire unit.
