It sounds like a problem with what they call "deflection". I don't know about VT101's specifically, but there are usually a set of pots on the CRT logic board (the PCB mounted on the rear of the tube) you can adjust for such things. Check out this section of the Monitor Repair FAQ: http://www.repairfaq.org/sam/monfaq.htm#mondefl Depending on the type of distortion you are seeing, you'll need to adjust the pots to compensate. -Swift
