I have a question about the CCFL backlight found in LCD monitors. I have two HP L1950 LCDs which I am using in my dual monitor setup. I got these second hand a while ago and they've been great LCD monitors overall, haven't had a problem at all with them.
A few days ago (after months of use) I discovered that when you go to "information" in the OSD, it tells you the back light hours. The main monitor (1) has 3200 hours on it, the secondary monitor (2) has 4590 hours on it. Now I don't see a problem with these displays AT ALL. Colour is great and they aren't dim though I will say that the LCD with higher back light hours is slightly dimmer and a tiny bit more yellowed in colours than the latter as expected due to the hours difference.
But then I was looking up this stuff since I'm getting interested in this "backlight hours" feature, but then to the death of all glory, these CCFL bulbs only last 5000 hours and then die?
I did the maths and worked out that if an LCD is left on 24/7 (which many are), that's about 7 months straight 24/7? I've seen LCDs in workplaces and shops even older than these stay on 24/7 for more than 18-24 months without a problem. :S
Can someone enlighten me on this stuff? (not in the mood to get new displays... yet).
On a side note, I ALWAYS buy my IT stuff second hand for peanuts because I don't see the point of buying brand new or current top of the line etc. if all I do is browse the net and watch Youtube.
