The LCD monitor brightless depend on the CCFL tube inside the LCD monitor. For the low end / or cheap CCFL, after 1000 hours running and the CCFL may be dead or running in less of power too. So the brightless of the LCD monitor something relared to the CCFL. (Or course, the power inverter board also be a factor)
So some of the good brand LCD monitor even running for many year that still in good condition and some of the low cost model may cause problem.
I have recently bought a 19in acer AL1916W LCD monitor to set up a dual monitor system.
My other monitor is a samsung syncmaster.
The samsung is less then a year old while the acer is 4 years old. I bought the acer for $50 second hand. the samsung is brand new.
now when I set up the two monitors and there is a noticeable difference between the acer's brightness and samsung's brightness, the samsung being the brighter.
I believe that this difference can be attributed to the age of the Acer. Can anyone confirm that? And if so, is there any way to fix it.
I have already tried to adjust the settings on the acer and haven't seen much improvement.
