. It has an antiglare coating that gives it a dull shine when turned off. On a reflective screen like or Dell screens with TrueLife you'll easily see your reflection with the screen powered off. The coating is not annoying and appears to be uniform over the panel.
Unfortunately, here is where the Samsung LCD panels fail. Black is some shade between grey and black over the entire screen. There is even a characteristic pattern in Samsung screens where the center seems to have the least leakage and there's a small circle about the size of a USA quarter in the top center where there is no leakage at all. If you like deep true blacks then this system will not please you. However, I do want to note that normally it's not noticeable unless you're playing a dark game like Doom 3 or others where there are large dark areas on maps. Light leakage on both the 6000 and XPS2 Samsung screens is minimal at the bottom, but it is there.
Color on the 6000 and any Dell Samsung screen is warm and dull without adjustment. You'll want to immediately jump into your video properties and adjust your contrast, brightness, and others. I like a contrast of about 111%, brightness of 98%, and a gamma of 89%. One of the drawbacks of having an ATi card is that there is no digital vibrance control which really livens up the picture on my XPS2 to make the colors on par with a Sony and Princeton Graphics Senergy LCD. You'll want to play with the color settings and other programs at some point if you're really concerned about having your colors jump out and catch your eye. For most people the simple adjustment I outlined above should be enough.

The backlight is not functioning, check the cables between the monitor and the motherboard, make sure backlight is at max, theres a button combination for that and it debends on laptop, surely documented in the manual.
you need to replace the backlights most likely

Dull laptop screen back light


You may have a faulty CCFL lamp. A faulty CCFL lamp may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering and/or with dim display or appear black. Picture flickers on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replace the CCFL lamp.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight or a faulty inverter that supplies high voltage to the CCFL lamp. Usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

My acer 9300 when switched on shows a blank screen (black with some faint white back ground) but the process of starting windows goes normally coz i can view this when connected to a monitor whats a miss ?...


If you see a very dim image or black screen or flicking image on the LCD screen it means you have a backlight problem.

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.

Dell inspiron 5150 dark screen, faint image in background


If it showed a pinkish tint on the screen before it went out it could be the backlite. If you can see a faint screen when you turn the room lights out it chuld be the inverter. Inverters are cheap ... a used one for around $8 on ebay. Try that first. Make sure that you buy the EXACT model that is presently in your laptop.

Dark screen with dull image in background


You may need to check your desktop image for your monitor and change it to something lighter
The external monitor usually uses your computer's default and not ncessarily the one from your laptop monitor

Without taking it apart myself, it could be some wiring from the laptop to the screen
