HP no longer sells individual display components. That makes any upgrades difficult. I wanted to document some info for 4540S series and hopefully someone will post similar info for 4740S.

15.6" display is made by LG PN: LP156WH4
4540S standard LVDS cable PN: 50.4SJ06.001
4440S standard LVDS cable PN: 50.4SI04.001
4740S or 4540S(with 1080p screen) dual-link LVDS cable PN: 50.4RY03.001

Huge Thanks to Don_Grappler for taking his 4740S screen apart and providing PN !!!

So, these are just the normal replacement parts, or are they the 1080p/dual-link ones you're going to need to do a 1080p upgrade?

Just replacement parts at this point.

Does this apply to all their laptops? I bought a dual link screen cable 2-3 weeks ago.

Sorry, I was thinking about new 4x40S series when made this statement. If you look at the manual it lists "Display Assembly(Screen+cables)" instead of individual components. Same for 4740S. We have to rely on people taking apart their laptops and post their findings.

I was quietly hoping for the cable being dual-link ready. Unfortunately, connected 1080p screen has green background with existing display cable.

I noticed that the dual-link cable is thicker than the stock one. So, you can distinguish physically too...

So standing right now, the dual link cable for 4530s is NOT the same for the 4540s, part number: HP 646274-001. Do we know if the 4740s is a dual link cable yet? The part number for that?

4740S LVDS cable is dual-link because of the laptop LCD size and one user upgraded to 1080p. What we don't know if the length and connector types are suitable for 4540S. Part number HP offers is for the whole display assembly (LCD + cables) and is probably in $300-$400 range
