I don't know whether it's the cold weather that is causing this or the backlight of the monitor is going to die soon. For a period of ~30 seconds, the backlight will grow in intensity until it has reached full brightness. It starts out very dim and the light is visibly flickering until it reaches full brightness. It is about 60F / 15C degrees where this monitor is. Today, it was a slightly colder and the backlight appeared totally off for about 10 seconds, until it was visible, and this is worrying me that it may soon die. Once warmed up, the backlight exhibits no problems whatsoever. Once warmed up, it can be turned off and back on without the startup-dim-flickering problem. What are your thoughts on this?
