Acer 5740DG LCD Replacement (Stuck pixel)?

Hi there, i have just got a new Acer 5740DG. When i first opened it i noticed a green (since it is not visible to green and white? patterns) dot in the center of the screen (so i assume that it is a stuck pixel). Are there any remedies for that?

I saw on the net a uk seller that offers full HD (1920X1080) screens at 15,6 size (at the moment it has 1366x768). Will it fit and work if i exchange it???

 

It prove problematic- you need dual-LVDS for Full HD screens while 720p ones need only single LVDS.
Usually notebooks that are offered with 720p screens only don't have dual-LVDS. Service manual for 5739G doesn't mention dual-LVDS either.
The easiest way would be probably to send it back or RMA it- depending on how these things are handled where you live.
Check the conditions under which the LCD gets replaced- it's in the owner’s manual.

 

Unfortunattely i called the Acer Service and it is not covered. Is the 1600X900 dual LVDS (by the way what is LVDS)?

 

LVDS is Low-voltage differential signaling system- used to connect your LCD to the notebook. It uses 20pin connector (single-only) or 30pin connector-however single-LVDS doesn't use all pins on 30pin connector while dual-LVDS does (see here pages 19 and 20).
Single LVDS is said to be used for resolutions up but excluding SXGA+ which is 1400x1050. If you connect anything above that to a single LVDS you're going to have every second line displayed only.

 

Anoyingly Acer tends to keep their two cables very separate on newer models.

While the smaller monitor size cables all have the pins for dual LVDS the actual cables are missing while their dual LVDS cables use a different design.

I tried soldering on some, but its too small for manual soldering.

 

Interesting, so there's no Acer with native dual LVDS sockets?

 

As far as i understand we exclude fullHD resolution. What about 1600X900 resolution? All my screens that i work are 1920x1080 (the laptop i am using now is a 5 year old dell with 1920x1200), so getting after 5 years an acer with 1366x768 it seems a little odd to me...

 

Well it depends really.

If its the same as the 5935 -> 5943g series connector then the pins are there, its just there is no dual LVDS cable made.

If you managed to find one I see no reason why it would not work.

Of course I failed after a month of researching.

Anything above 1400x900 requires dual LVDS.

 

So anything above 1366x768 (in the 16:9 category) is dual LVDS?

And how might a greenhorn check for if the laptop has dual or single LVDS? Is there a software solution to that?

 

No. Have to check the cable going into the LCD itself to be sure.

 

That's a dayme shame.

 

So the 1400x900 is dual or single LVDS?

Sorry i had not seen that. Regards

 

IT suddenly came to me and i would like to ask... My brother has an HP Envy with 15,6 screen but 1366x768. Is it possible that i can pull out the cable and be a dual LDVS one?

 

Different manufacturers use different cables, heck even the same manufacturers use different cables for different models.

 

So whatever happens acer will remail with 1366x768 resolution... Iwould like though to hear a succefull story of uprade
