You know better, if you let a CRT monitor keep an image on its screen for a long time it makes tracks on it.

Is it same for the LCD monitors? Is it a must to use screen saver for LCD monitors too?

Thread starter asked whether a screensaver is needed for LCDs. The brief answers from and are helpful; this note adds practical, evidence-backed guidance on what actually matters for modern LCD panels and what steps reduce the small remaining risk of ghosting.

The main phenomenon to know is image persistence (temporary pixel “ghosting”) rather than the permanent phosphor burn-in that affected older CRTs. Image persistence is usually reversible and is caused by prolonged static images or charge effects in the liquid-crystal layers. For a concise technical overview see Image persistence and the contrast with classic burn‑in at .

Practical recommendations based on manufacturer guidance and long-term field experience:

  • Use OS power settings to turn the display off or put it to sleep after moderate idle time instead of relying on animated screensavers.
  • Reduce static high-contrast elements (toolbars, status bars) if an application must run 24/7; enable any native “pixel shift” or pixel-refresh features in the monitor menu.
  • If ghosting appears, power the monitor off for several hours or run a full-screen color-cycle/white image for a few hours — image retention typically clears.
  • For kiosks or signage, choose panels designed for continuous static content or use purpose-built hardware/software to cycle pixels.

If image retention persists after these steps, escalate to the display vendor — long-term defects are uncommon but warrant warranty service.

Nope, LCD's do not burn in like CRT's and plasma displays. LCDs are great especially for that reason so you have no need to worry about that. Also it is not a must to use a screen saver for a LCD neither.

it used to be the case for LCDs btw in like the early/mid 90s - thats why win95 and 3.1 have schemes where all the white bits are black and vice versa so that it reduces whiteon, but no. not anymore

i been running a 19" LCD (dell) for 2 yhears 24/7 - no burnon
ive actually had a crt running since 1997 its kinda yellowy now and theres a green blob in the top right corner and a red hadow in the bottom right
