    I've been searching everywhere for a replacement to no avail.

    -1600x900
    -14"
    -30edp
    -Slim type
    -Glossy
    -TN LED

    It must exist somewhere! Would appreciate any help!

    PWM is max 500hz on the Innolux N140FGE-EA2.

    max 10,000hz on the B140RTN03.2

    So may have to stick with the AUO B140RTN03.2 and convert with the 40 to 30 pin edp.

    Ok so it seems the AUO B140RTN03.2 is perfect except for one hiccup and that is it's a 40 pin edp LED and my computer has a 30 pin edp connector.

    Is there anyway to change this out? Perhaps I can hook up a a 40 edp connector straight to the mobo?

    Anyone any ideas I am a noob at this.

    Ok can't go from 40 to 30 edp.

    I have found that the Samsung LTN140KT14-401 Slim 14" panel apparently also came in a Glossy finish, it has 10000hz pwm so would be perfect, if I can find it!

    Don't stare too blindly at an exact 14", 30-pin, 'slim type' or glossy.

    With a little adjustment of the bezel and/or display lid a non-14" and/or non-slim can be made to fit. A 20- or 40-pin can be made compatible by modding the cable, but don't think there's many of those panels in the first place; almost everything eDP at this size is 30-pin anyway.

    The glossy or matte denomination is merely the specific finish of the outermost, draped-on sheet. Since you want glossy it's a relatively simple process to remove the matte finish by stripping the sheet. The other way is more difficult to do right, as it's very hard to apply that layer without specks of dust getting trapped between the polariser and the newly applied matte sheet.

    That's an LVDS, hence the 40-pin. If it were an actual 40-pin eDP then it most likely could be modded to accept 30-pin input since not all pins will be in use and some can do double duty.

    Hmm, you have to realise that many 'model #xyz' panels listed as either 'glossy' or 'matte' are actually manufactured in both varieties. So when used in one laptop brand they'll have a glossy finish, but in another it'll be matte (different production batch). Best option is to insist upon glossy with the seller when ordering an exact panel.

    Comprehensive search list; ~14", eDP, panel, ppi ≥ 120 and brightness ≤ 250 cd/m². This also includes blank listings under 'brightness' (= unknown value), just ignore those.

    edit:
    And please don't start a new thread each time your initial question shifts a little. This your fourth thread on the same, basic issue:

    You are right, I'm sorry! Just I'm a complete noob trying to make it happen! I keep coming back to the forum and forgetting I already created a thread. I do keep getting close to the solution and I really appreciate your reply.

    Do you mean a 14.1"? And how on earth would you mod the cable? I was told by a computer shop that going from a 40 pin edp to a 30 pin edp is impossible.

    I'm concerned about stripping the 3H layer though, I'd want to reapply a protective coating.

    No problem :vbthumbsup: .
    Not all pins will be in use; a 40-pin may actually use less than 30 and a 30-pin something like 25. Part of them are only used in the factory or have been designated for error-checking, a moot exercise since people just buy new panels instead. So it's possible to cut the cable and reconnect (solder) the individual wires, joining backlight voltages and grounds, if necessary.

    This specific mod is not required here, though; all matching panels are exactly 14.0". Though there are one or two 40-pins, don't think you want to take those extra steps since there's plenty compatible 30-pin panels to choose from.
    Yes, that's understandable. You can get a 3H film to re-apply (simple sticky adhesive) from Photodon; MXA: Crystal Clear or MXB: Blue Light Cut. Since you mentioned headaches and wanting lower brightness, the blue filter might be a very good idea. Blue being the most energy-intensive wavelength it'll do much to drop overall light output, obviating the need for pwm. The blue-ish tint can be compensated for by tinkering with the colour settings of the display driver.

    As for stripping the old layer; try it out on a cheap, spare or semi-defective lcd first. The polarizer sheet is right underneath the 3H+glossy/matte sheet and has a similar form and thickness. When you've got a small edge loose try and see if it isn't actually two sheets stuck together by trying to splice them. If so, just push down the polarizer against the lcd and no harm will be done.

    Ok well, I've got a new 1600x900 matte TN AUO screen, which should be a sufficient downgrade and I'm ready to do the P645 screen swap and upgrade (downgrade).

    Now it's a long time since I've ever done a laptop disassembly and I usually strictly adhere to a guide or manual.

    Trouble is I can find no such user guide manufacturer or independent online. Does this mean I'll have to progress with this in the dark? Anyone perhaps done a disassembly of a P645 screen?

    Just did the panel swap it was a relatively easy process and painless.

    I may have pulled a little hard on the sticker holding the edp cable to the panel, so it's not as sticky now on the new panel.

    I always use a small piece of duct tape/sellotape to make sure the edp cable is correctly fixed on the screen because indeed it loses 'stickiness' when you change the edp panel, but if you don't have a problem forget about it ;).
