    I'm looking to upgrade my HP ZBook Studio G3 from the stock 60hz screen to a 144hz panel for gaming purposes. Does anyone have experience with upgrading a from an FHD 60hz screen to an FHD 144hz screen? Would be willing to pay for assistance.

    The screen in my laptop is eDP (2 Lanes), 30 pins while all the 144hz panels are eDP (4 Lanes), 40 pins. Does this mean they're incompatible? Or do I simply need the right cable?

    I've purchased a 144hz panel (AUO B156HAN07.0) and an HP ZBook G3 UHD cable (DC02C00C900). For whatever reason the cable connector is not as long as the display connector even though they're both 40-pins. Why is this?

    @t456 - you're my only hope

    Product Number: T6E16UT#ABA
    Serial Number: CND7067C9N
    Screen: LG LP156WF6-SPB1 / LP156WF6 (SP)(B1) 15.6" 60hz

    Haha, surely not :vbbiggrin: .
    It depends on the laptop; if it can run 4 lanes yet only has a 2-lane panel then it's indeed a matter of getting the right cable. Some of the cheaper systems are actually limited by the motherboard to 2-lane, but a ZBook will do fine.
    What panel is the official 3k/4k option that HP offered for this model?

    It might be that that screen has its connector on the bottom-left and the lcd cable threads through the right hinge; the cable wouldn't have to travel across the width of the panel, so it could be made a fair bit shorter. Just speculation though, but lcd cables are never too long for the system+lcd combination they're officially intended for. An overly long cable is no problem, but the reverse situation is very troublesome.

    At the very least you could run the panel; leave it propped on some cloth and hook it up. Just be dead certain to remove the battery before dis- and reconnecting display cables. The connectors are 'hot' and with a 0.4 or 0.5mm pitch it's quite easy to short some of them.

    Awesome! That’s good to know. Hopefully this ZBook is 4-lane.

    These are the HP part numbers for the panels they offered. I haven’t yet found out the true part numbers on the panels.

    • 840941-001 (FHD)
    • 840943-001 (UHD)
    • 840945-001 (UHD)
    • 840945-001 (UHD)
    • 840947-001 (FHD)

    I think it phrased it incorrectly but I’m referencing the connector on the panel itself, not the length of the cable. Neither the connector on the original HP cable or the HP 4K cable I purchased physically match up with the new panel. Haven’t even tried to determine cable length yet. What do you mean by pitch?

    Ah, then that'd be the pitch that is different; 40-pins at 0.4mm interval (pitch) will give you a smaller connector width then 40-pins at 0.5mm pitch. That and the connector location would be reasons to offer different cables for the same system. That there's 3 UHDs bodes well; likely one of them will be compatible with the HAN07.

    The ZBook is 4-lanes, no worries.

    Oh, gotcha! What do you think is the easiest way to determine pitch on cables and panels? There must be an easier way than ordering and measuring. I didn't see any specifications online when looking at panels & cables.

    Great to know the ZBook is 4-lanes.

    Most cables won't list this, but that information is available for all panels. So you need to find out which UHD panels correspond to those HP part numbers and then check which of them use 40-pin with 0.5mm pitch (on Panelook, for instance). The HP cable that corresponds to that panel is the one you need for the HAN07.

    If you're good with small-scale soldering then you could also diy your own cable. Would need to find some cheap 4-lane, 0.5mm pitch eDP cable and use its lcd connector half to make a hybrid with the 4-lane HP you already have. That would mean soldering some 30 small wires though. Also heatshrinks around every one of them, of course. Best place to make the cut is near the motherboard end; that way the soldering joints can stay relatively static whereas the cable section that routes through the hinge suffers quite a bit of stress.
