Is a monitor damage possible without video amplifier?

[Haggar]

I have an Intervideo 28" 15KHz Monitor.
I have attached my PC directly to it (via RGB cable) and I use soft-15KHz to force the video card.

The image was initially very poor of colours, but I rised the RGB levels (with monitor pots) and now I have a perfect image.

I know that vga levels are 1v vs 5v jamma levels and that there is a video amplifier to fix this gap.

BTW with pots I've reached a perfect image. The question is: Do i risk something rising these rgb level pots?

I've read on a FAQ somewhere that while you wont' do immidiate damage to the arcade monitor. Over time you are essentially boosting the power through the monitor and limiting the lifespan of the monitor. $20 for a amp and cable from Ultimarc or a costly monitor repair?

as long as your not overdriving the crt cathodes , i wouldn't think a huge problem for home use .
however, extended operation at high levels can shorten crt life. ( 24/7 for a couple of years  )
crt's are a vacuum tube .  tube cathodes can produce electrons for a period of time before the material begins
 to wear .  as this occurs, the device beam current will drop ( weak tube ) . this applies to all hot cathode tubes
the rate of deterioration is affected by the beam current . high current /time = short life

Thanks for your answers.
