Help me speculate please

Will those fit? (Click images for high res)


Background:
- The second image allegedly shows a 30pin eDP port of a Full HD panel.
- The only information I have about the plug in the first picture is that it drives a 1366x768 panel and it appears to be a 30pin connection also.

While a LVDS connection would be sufficient to drive a 1366x768 resolution, could it be that the plug nonetheless uses eDP too?
Especially since eDP seems to be the new standard in notebooks and this is a plug of a 2012/2013 notebook!?

 

Hey

Even though it might physically fit, its not the same thing electrically. So the cables are not the same and are not compatible with one another. Also there is no eDP signal on a laptop thats designed for LVDS, its totally two different things and signalling types, it comes from the motherboard.

 

But what makes you assume the laptop uses LVDS? Just because it drives a 1366x768 panel?

The laptop manufacturer won't disclose the model of the panel, nor which technology is used. The only information handed out says it's a "standard connection".

The replacement panel shown btw is a CHIMEI INNOLUX 11.6" Full HD N116HSE-EA1 used in the Asus UX21A. According to a custom system builder who uses that display the eDP pins 1, 24, 25 and 30 should not be occupied when driving this display.

Which leads me to question the compatibility of the plug as it doesn't seem to follows that approach. Although the cable shows ~30 wires could it be in fact a 40pin LVDS plug which just doesn't make use of all its pins!?

 

The number of video data and DC voltage channels used are more important than the physical connector itself. Most display panels in your size range are either 30-pin or 40-pin yet are still LVDS single or dual channel devices. It is how the manufacturer wires them up on the system board that matters. Most 720p systems simply will not support a higher resolution display panel unless you can find the same model being sold with the higher resolution option. If so, this means the correct LVDS cable is made and may be purchased. If not, then it may not be worth it unless you have a schematic of the system board and the resources to make a modified LVDS cable *IF* the you confirm the GPU circuit is set up to handle it. Typically, 720p requires only one LVDS channel be interfaced, but 900p and 1080p almost always require the two LVDS channels with additional V+ lines.

In regards to the eDP, it is different in terms of it is typically integrated into the same video bus as the HDMI. Unless you physically see two separate video headers (1 LVDS and 1 eDP), it is a safe bet you do not have eDP available on the system board.
