My screen may have been made from a BMW's Tail lights?

i've had my HP Dv4 for under a week now and i was wondering...how do i know whether i have an LED display or not? i mean, it didn't notice anything on the box but i guess i wasn't looking for it, is there any difference in the appearance of an LCD and an LED?

 

That is what I want to figure out for the last 2 months no one can give a nice answer. This is what I like about HP...

 

Did you order an LED screen? The LED screen does not come standard on the dv4t, so unless you paid the extra and upgraded, you likely have the normal backlit screen.

Apparently the LED backlit screen is much brighter than the normal screen and it uses less power. I'm about to order a dv4t with the LED, so it'll be interesting to see how it compares to my other laptops.

 

I didn't order anything, i bought the laptop from a retailer.... It's a Dv4 1070ee it's my first laptop so i wouldn't notice if it's brighter than others...isn't there any other way to know whether it's an LED or not? like my computer properties or sumthing?

 

Oh, that makes sense.

Don't quote me on this, but you may be able to go into Device Manager, expand Monitors and double-click the entry there. Then under Details, check to see what Device Instance ID says or Hardware ID. Then you'll probably have to google that code to see which it is.

Otherwise someone a bit more knowledgeable should be able to help you.

 

it didn't work, but that's ok i don't mind either way, but just one other question...is it possible for the screen to be an LED if i have the infinity display?

 

scrap that i found my model on the HP website, no LED screen. but the infinity thing is still really cool

 

Good work.

 

The other thing I noticed with LED screens are that when you increase or decrease brightness, the adjustments are in discrete steps, unlike CCFL ones where the brightness change has a smooth transition effect as it takes a while to adjust.

 

Good point. I think sometimes CCFL screens take a while to light up fully, or at least my Dell flatscreen does. Or maybe it's just my eyes.

 

I went to the retailer again today and i couldn't find any laptops with the LED, i guess it's kinda rare..

 

Its not you.
Its a fact, my previous Compaq with its CCFL screen also took a few seconds to fully warm up whereas LED backlit screens light up instantly.

 

LEDs are only rare because right now they're either not available with different laptops or they're an extra upgrade. Hopefully CCFLs will quickly become a thing of the past.

And thanks for the assurance Rahul. ;-)

 

cool, thanks for the info

 

I've seen where people have upgraded the LCDs in their laptops (going from say, 1600x1050 to 1920x1200). Is there any chance such a thing might be possible with the backlight, too, or is there just too much CCFL-enabled circuitry for a simple direct plug-in?

 

kcrudup, you're asking the wrong guy.

I'm guessing that yes, the backlight may actually be an integral part of the screen. However, you could probably get another laptop exactly like yours and swap out the entire screen.

Anyone else?
