LCD PC monitor can be "quite" easily tweaked for 15kHz... CRT is a bit different thing - impedance for all inductance's will be to low, so You need to add variable voltage power supply for whole H circuit, change components (RC) - it can be made but... IMO not worth to bother.
LCD monitors are easier to tweak - only need some uC with usually I2C port and modify some values for AFE and ADC (syncing. levels, sampling, clock recovery) - if You find datasheet for AFE it should be "quite easy"
