Hi,

I currently have a BenQ RL2455HM monitor and i'm just curious whether if i turn down the brightness of my monitor, would it increase the life span of my monitor? Would it be better for my monitor to decrease the brightness? Does high brightness dim the monitor in the long run?

Thanks :)

Nope, unlike CRTs and plasmas where the primary component of the monitor provides the brightness and the colors, LCD screens have it separated.

On a CRT screen increasing brightness would decrease screen life and increase burn in because you are increasing the power of the beam you are blasting at the pixel to turn it on, we don't do that anymore with LCD screens.

Brightness has no impact on the LED portion of the display, the brightness is controlled by the CFLs or LEDs around the edge of the screen, the image and colors are controlled by the liquid crystal in the main part of the screen, the crystals don't degrade due to visible light so brightness isn't going to impact how long until they get stuck or die, that is still going to be random.

Most monitors out there will drop into a super low power mode, if i turn my computer off within 3 seconds both my screens have turned off their LCD and their backlights, the only thing still churning is the controller waiting for a signal to come back to turn them on, so if you are letting them drop into a low power state you won't decrease their lifespan.

If you are not letting them drop into their sleep mode though you will decrease their lifespan, while ghosting and burn in are significant considerations for CRT and plasma screens(an hour of the same image can cause notable issues), LCDs are not immune to it, the monitors in the engineering computer labs at my school had a very distinct ghost of where the windows "Press CTRL+ALT+DELETE to log in" window sits on windows XP, granted they had probably shown that same image for hundreds possibly thousands of hours but burn in does happen on LCDs just very very slowly. Let it drop into its sleep mode and you will be fine.
