- Sorry, my mistake. I meant plasma when I said phosphor.
-
- Exciting a plasma generates heat which IMHO I suspect affects the display.
- This display has a definate shadow of the Lanalyzer display on it. It
- can still be seen when the unit is switched off as being darker than
- the uneffected area of the screen. The operation of the screen is not
- adversely affected apart from this shadow.
