    Im posting this hoping somebody is willing to lend advice. If this isn't the right forum or site to be posting this stuff on please do let me know.

    After looking into the different panel pricing my preferred panel is not available anywhere for under 400usd. Preferred panel is Sharp LQ156D1JW31.

    My second preference is the Sharp LQ156D1JW02 (still an amazing panel however a little less bright at 350 and not 400 though, even 300 is enough frankly), This is/was the best upgraded display available on the dell precision m4800 and got insanely good reviews by anyone who ever saw it. It also uses less power than the jw31 which is good. It also fits depth wise and height and width wise.

    I found a used in perfect condition Sharp LQ156D1JW02 for 129usd with 50usd shipping from http://www.elecok.com/lq156d1jw02-15-6-igzo-tft-lcd-panel-for-sharp.html . They had one left and I got it with a 3 month warranty.
    My other alternative was to buy one from dell (Dell 072yhk dell part number) at 629USD plus shipping.

    I still need to order the bezel from msi which i will do this Friday or Monday when my gs63vr laptop arrives.

    I need to get a 4 lane 40 pin cable from the screen to the motherboard. I think I will use the one that comes with the 4k model of the gs63vr (the 1080p uses a 2 lane 30 pin and the 4k uses a 4 lane 40 pin) and will order it along with the bezel needed for the switch from MSI. I have been told that both of those (30 pin 2 lane 1080p capable & 40 pin 4 lane 4k capable) ends will fit in the motherboard as the 30 pin connector has 40 pins but only 30 wires attached to it hence its called a 30 pin?). Can someone confirm this?

    If anyone has any knowledge about these connectors and can confirm if the 4k 4 lane 40 pin cable will plug into the screen I bought? Heres the link to the screen i bought.

    http://www.panelook.com/LQ156D1JW02_SHARP_15.6_LCM_parameter_24748.html

    Last question is does anyone have the panel model number from the 4k version of the gs63vr?

    Any help or suggestions appreciated. I am willing to post pics when the panel switch is made and also make a video.

    With thanks

    Keep us updated, I want to see how this goes. I'm also trying to figure out how to learn, in part, what you just brought up about 30 pin and 40 pin connectors, so that when it's my turn I'll be able to swap my display.

    Capjack I will be happy to do so.

    Currently i plan on ordering the gs63vr 1080p screen to motherboard cable (2 lane 30 pin i think it will be) and the 4k gs63vr 4k cable (4 lane 40 pin i think it will be). If anybody knows if the connector on the motherboard for these cables are the same? I think they are as pics of the 2 lane 30 pin cable show 10 pins without a cable attached meaning 40 pins total. I cant locate a pic of the 40 pin 4 lane cable yet as Im hoping someone with the gs63vr 4k screen will post the screen model number so i can confirm the connection type/cable type.

    I do want to mention that I have emailing a guy named Tom at MSI and he has been VERY helpfull providing all the info that he can and has responded to all my emails within a day. I really hope I can find a disassembly guide and a schematic and/or white paper on the gs63vr as that will answer all my questions I think or at least give me the raw info to little by little get the questions answered. I want to avoid opening up my gs63vr until i have all the parts ready so that it doesn't become unusable waiting for parts. Im a gamer and I dont want to keep on using the 765m im using now as I wait for a cable or connector or adapter:(

    Im really hoping Derek712 will chime in on this as he is a god in terms of knowledge. Anyone else with any knowledge your input would be greatly appreciated too. Please help :)

    Update. My gs63vr arrived. It's amazing!!!! Aside from the crap screen it is a beast of a machine! I have not had the gtx1060 throttle even once. It is thin, light and an absolute pleasure to type on.
    I have the stuttering issue that some people have mentioned and am working with msi to try to sort it out. It's a great keyboard but frustrating when a few times a minute it completely freezes.

    Currently. Awaiting delivery of my sharp lq156d1jw02 panel. It is new and not used. I was under the impression from the price that it was an a- condition but I was wrong. :) 179usd shipped total :) (Dell wanted 629 for this panel). I had a concern that the screw holes are on the left and right for my new panel and not above and below like in the screenshots of the panel in the disassembly guide of my existing panel however in the same screenshots the screw holes above below/left and right can all clearly be seen. Makes sense considering the laptop has to be able to acommodate a variety of panel manufacturers standards.

    Cable - Tom at MSI has sent me the dissassembly guide for the gs63vr 6rf. I dont know if it is the same as the 4k one (I dont think it is) but I am requesting the disassembly guide for the 4k model also.
    I have ordered a DIY I-PEX 20525 40Pin LVDS EDP Signal Cable DIY 0.4mm Pitch with 30P Connector Port from ebay. From the dissassembly guide pics it appears to be a 40 pin motherboard connector.
    It says it is an lvds cable in the pics however edp is connection protocol I think and lvds is cable type I believe between the edp 1.3 connections??? I will be going from a 30p 2 lane to a 40 pin 4 lane cable. I dont know if a 40 pin 4 lane will suffice for uhd at 8 bit. Does anybody know? Does anybody know if the MSI gs63vr 4k cable is 4 lane?

    If anyone has the 4k version of the gs63vr please tell me your panel model. With this I can tell what type of LVDS cable is used (2 lane, 4 lane etc) by checking the panelone website.

    The 20525 is the edp connector that fits into the panel I think. The end for the motherboard i am unsure of and will be ordering the 4k lvds cable from MSI along with the bezel probably tomorrow when I have time.

    If anyone has any thoughts/suggestions I would appreciate it.

    Regards, Josh

    That is very probable; often several voltage and ground pins on the lcd side are joined into a reduced set on the mb side. There's also a few 'manufacturer-only' pins that aren't used at all once the lcd is installed, so these will be omitted from the mb connector.
    The cable can handle LVDS and eDP both. These designations are merely the protocol that is used, not the physical cable type (which is more-or-less identical). Only thing of concern is whether all pins are populated on the cable (they are) and whether the pitch matches (it does; 0.4mm for both).
    Easily; you have ~26 Gbit/s at your disposal and 2160p@8bit only needs about half of that.
    Most likely. It is technically possible to (barely) make do with a 2-lane cable, but either it'll have hiccups or they'd force it to run at 48Hz. Neither scenario would go well with a high-end system, so chances are good it's a 40-pin/4-lane cable, as are all lcds in this range.
    The cable you ordered is diy and cannot work 'as-is' with any laptop connector. The 4K MSI cable may work, provided it is meant for 0.4mm pitch panels, same as the W02 you've ordered. If it has a 0.5mm lcd connector then you'd have to cut both cables and solder the wires back together, using the lcd side of the 0.4mm diy cable and the mb side of the 4k MSI cable. The 1080p MSI cable will not do; it won't have all the necessary pins populated. With this 1080p 4 or 6 will be missing, since 2-lane does not require them and $0.0007 saved = $0.0007 earned :vboops: .

    t456 I cannot thank you enough. You have greatly helped and given me more answers than my last 8 hours of browsing. Hopefully the 4k msi 4 lane connector will be plug n play so to speak and i wont have to get a custom cable made (fingers crossed). Im not experienced with soldering and wouldn't want to screw it up. Im thinking I will use quadrangleproducts to build a custom cable if needed as they do custom ldvs/edp cables unless I can source a great solderer in Toronto Canada. Im very happy to hear that I have 26Gbit/s available with a 4 lane 40 pin as I read on another thread (intel forum somewhere) that it was far less and wouldn't be sufficient. My only remaining concern is voltage and pin assignment. i will not be ordering the 2 lane cable and will only order the 4 lane msi cable as per t456's advice.

    1) The pin assignment on edp 4 lane 40 pin panel connector is standardized correct? Meaning I wont have to change pin assignments as my ordered panel uses edp1.3 like the msi panels do?

    2) The lamp driver board(backlight) on my current panel shows 5.5/12/21v, 250/260mA,3.0/3.1watts ( and on my ordered panel shows 7/12/21v, 497/627mA,5.05/5.52watts) Will I have an issue here or will it automatically draw the power it needs from existing pins?

    3) Panel input voltages match up at 3.3v however my new panel is 497/627ma, 1.64/1.88watts and my existing panel is 330/390ma, 1.1/1.3watts . Will I have an issue with these differences?

    HUGE THANKS TO t456! Any help from anyone appreciated! Also if anybody needs the gs63vr dissasembly guide that msi sent me just ask and i will send it to you.

    If anyone has the 4k gs63vr please post the panel model you have. You can use HWINFO (freeware) to check. This will help me determine pin pitch on the panel side of the gs63vr panel->motherboard cable used.

    With regards & thanks, Josh

    Good luck with the upgrade, It's a bold move. When they come up with a 1440p screen for the GT73 I'll be looking you up.

    The 4k model gs63vr panel is the LP156UD1-SPB1 . I read this on http://www.ultrabookreview.com/12557-msi-gs63vr-review/ just now.

    Panelook info: The pixel configuration is listed as RGBW Rectangle. I think that means it's 4k pentile :(.

    I think if the pixel configuration was listed as RGB vertical stripe then it would not be pentile and thus would be better as RGB vertical stripe has a full 3 lights per pixel?

    With this info I was able to ascertain that the pin pitch is .5mm on the 4k monitor 4 lane 40 pin panel side of the cable. The MSI 4k 4 lane 40 pin cable will not work as it wont fit into my new panel. The connector I ordered will fit into my new panel and I will have to either as stated by t456 (my new most favorite person in the world )

    "If it has a 0.5mm lcd connector then you'd have to cut both cables and solder the wires back together, using the lcd side of the 0.4mm diy cable and the mb side of the 4k MSI cable or

    get quadrangleproducts to build me a custom cable. Any advice? Also where would I look for someone to do the cutting and connecting as suggested by t456? Im in Toronto Canada and so if anyone knows any specialized technicians who could do a competent job on this please do send me info.

    With thanks, Josh

    John - Thank you for the explanation. Its 2 subpixels per pixel pentile and 3 subpixels per pixel RGB
