I have a an AOC TFT monitor LM520A and I have been trying to alter the brightness using the OSD but to no avail.There must be something wrong with the OSD as whatever the level is set at there is no difference on the screen. Any of you clever people out there have any ideas of how to cure this?
I already have the manual for this monitor and I have been doing exactly as it says in the manual,but still no difference. I wonder if the graphics card drivers need to be updated,although the computer is only 6 months old.
The life time of the back-light is limited. After 30,000 hours, the luminance of the light has been reduced to half of its original value.
Please send the monitor to an authorized service agent for service.
Hard to believe that the monitor has been used for ten hours a day for 3,000 days already, though presumably one might begin to notice a loss of brightness and contrast after two or three years fairly continuous use.
Yes.I am the seeing the slider bar move and the numbers increase/decrease as you adjust the setting.I have been into the graphics card settings,there are not many there,no brightness or contrast controls. The card is an nvidia Geforce fx5200.
What drivers have you got for your card? the new forceware drivers 56.64 give you controlls in the advanced settings i have then on my 440mx and other card with the same driver so i assume they would be there on yours as they nvidea cards.There is gamma,brightness,color corection,digital brigtness and hue.
