What is the most susceptible to screen roll?

[+Gemintronic]

I'm trying to determine the most susceptible display device to the screen roll that comes with going over-cycle. I figured the most touchy one is the one I'd use for hardware testing.

 

So far I've got:

A modern TV with RF tuner.

A VCR attached to a Commodore 1702

 

I need to get a plain, old CRT TV.

 

 

In any case, are my first two options good enough? Is a stand alone CRT TV with RF the best option?

With my Commodore 1084S I can tell if the program generates +/-1 scanline vs the prior frames.

 

You can easily test your displays using Jitter (scroll down to How to Test to find it). Use joystick to set the # to 129, then tap the fire button to simulate an over-cycle event. On my 1084S the top of the image (the transition from black to white) will visibly move whenever fire is tapped.
