How to tell if my Studio 1537 has a LED backlit LCD?

I wondered about this for awhile because I am starting to see some shadowing on the lower left and right hand corner of my LCD. I have about 14-15 brightness levels and I ordered the WLED LCD. Any ideas?

The black isn't as "black" as my 3 year old CCFL LCD, but it is bright (except in the two lower corners).

 

Which brightness level do you find comfortable for use indoors under artificial light (i.e. no sunlight)? If it's about halfway, it's likely a CCFL backlight. If it's close to minimum, it's likely LED.

 

It used to be at the minimum level but it's clearer if it is about 3-4 levels higher. I bought a Mini 9 at the same time and I like using it at 3-4 as well. The Inspiron 15 I just bought is pretty sharp at 2-3.

 

It seems you like low brightness even with CCFL screens.

Maybe you can search the Net for the part number?

 

I suspect the Hardware ID just refers to the manufacturer code and is not necessarily indicative of the type of display.

I forgot to mention the Mini 9 and Inspiron 15 both were ordered with LED backlit LCDs.

I came up with a test which seems dumb, but based on my knowledge of LEDs, they tend to have a distinct refresh rate. If you wave your hand in front of the display, the CCFL backlit LCD won't show much of a ghost image. The LED backlit LCD will cause the ghosting almost like a slower refresh rate. Maybe this is a flawed test but I have a few CCFL LCDs that showed consistent results compared to the 3 suspected LED LCDs.

 

If you ordered the WLED, then you should have an LED backlight.

Of course, one sure way to check would be to disassemble the notebook to see if you have an inverter. Only CCFL displays have them.

 

Is the inverter the part that gets really hot at the base of the screen?

 

The top of my screen gets really hot, specifically the area right behind the built-in web cam.

 

According to the dell.com configurator and system specs, all 1537 comes with LED backlit display (maybe except this: Hi Resolution, glossy widescreen 15.4 inch display (1920x1200)).

 

oh well why you just not go to Control Panel - Device Maganer -> Monitor -> Details -> Hardware IDs
Mine is MONITOR\LPLB80A!
Which must means LG Philips Led screen.

BTW Mastershroom can you check your too

 

mine is SEC5441

 

I know mine's CCFL-backlit; I got the base 1280x800 display, way before they started offering it in WLED.

For the record, my monitor ID is "LPL0000"

 

Mine's the "hi-res" 1920x1600 and the ID is LPL2D01. It is CCFL because it takes a while to warm up.

 

When I ordered all they had was LED backlit displays. I don't know if this was a regional thing. Dell also noted in the spec sheet they sent me before delivery that the display was LED backlit.

Maybe it says it somewhere in you hardware specs from dell in the display?

 

Where did you order yours?

Here in the U.S., the WXGA/1280x800 and WXGA+/1440x900 displays are both LED-backlit, but the WUXGA/1920x1200 display is CCFL.
