Upgrading a Laptop's WXGA+ to a WUXGA.

My laptop screen has recently been getting bands of scrambled picture and various other lines through it, and when I attach it to a external monitor it works just fine, so I've narrowed it down to the LCD having gone bad. My question is whether I can upgrade the current screen to one with a higher resolution, since I'm replacing it anyways.

Currently it has a Samsung LTN170WX-L05: www.datasheetarchive.com/pdf-datasheets/Datasheets-29/DSA-572940.pdf (data sheet for a matte L04 Model)
And I'd like to replace it with a Samsung LTN170WU-L03: www.datasheetarchive.com/pdf-datasheets/Datasheets-29/DSA-572939.pdf
The connectors and everything else looks like it'd be identical, but would it be compatible? Has anyone here had any experience with this type of modification?

I'm using a p105-9722 Toshiba laptop.

 

Have you ever used a WUXGA? I have seen several people complaining about the very high resolution screens.

My previous laptop had WSXGA+ screen and that was hard to use for long periods even though I have 20/20 vision.

If you are planning to go from WXGA to WUXGA, it may be very good to try a WUXGA laptop for at least 5 hours before the final decision...

Just make sure the voltage requirements are the same and that the output of the inverter matches.

I changed the lower res LCD panel for the WUXGA on my A.W. M17 and I couldn't be happier.

It is the single best improvement I've made to my rig.

Trying it out on a laptop for 4 hours might suffice. lol

 

Yes, my desktop screen is a WUXGA, I find the resolution extremely useful in Photoshop and other applications, I understand it makes things very small, and I know how to adjust them to make everything a bit more readable. I'm just concerned with the compatibility before purchasing a relatively expensive replacement part.

Edit:
Rob41; Where would I find this information for my current setup and for the prospective screen?

 

If the connectors are the same, all you'll need is the specs for both panels. If the power requirements are the same then it will work.

EDIT: For your current screen, the voltage may be right on the inverter. If you have access to the new panels inverter check that. Otherwise you may have to find a tech manual or contact the vender.

 

Know of any good sources that might have that information? It seems like as soon as you want to know anything remotely technical about the hardware all the websites, including Samsung, know nothing about what they are selling besides the part numbers.

Edit: I noticed that the interface on both is: INTERFACE | LVDS(2ch). Would that mean anything as far as compatibility? Or does that just mean the lamps will work properly?

 

Hi,

i'm trying just the same with a DELL vostro notebook.
lvds(2ch) means that there are 2 lvds channels. Many LCD work with more than one channel since their resolution would lead to high signal frequencies if using only one channel. This has nothing to do with the backlight.
But i think this is not the only thing you have to consider. I have replaced my Display B170PW03 (AUO) with a LTN170WU-L02 (Samsung). They have the same, 30-pin 2ch lvds interface, an it doesn't work yet.
Now i'm wondering wether i have to tell the graphic adaptor which resolution to put out, since the LCD always needs the signals suitable for its natural resolution. But i couldn't find it out yet.

What about your display now, does it work properly ?
