Searching for IPS Display specifications for HP 8770W

Okay quick short story. I bought a used 8770W last month from a pawn shop. Everything was great. 3 weeks into owning it, the screen went out. I arranged with a friend with a computer shop to get the screen replaced free (I did some work for it). But when the repair was done I discovered he replaced my original HP DreamColor screen with a generic marketplace TN screen. Well for what amounted to a free screen replacement, I'm not complaining, much. Except TN sucks and I want my DreamColor back.

The guy that ran the computer shop claims he was unable to source an IPS panel for my model laptop and claims he matched it close to the original.

So.. what I'm searching for is someone out there that owns an HP 8770W with an HP DreamColor screen to either grab a copy of AIDA64 or something and see if you could please get me the exact model # of the panel that it is so I can try to source down a replacement that's RGB-LED & IPS.

Here's what I've found so far in my limited searching.

An LG IPS display claiming to be compatible with the HP 8770W via ebay: http://www.ebay.com/itm/371790604259

So I searched down the model # (LG Display LP173WF3-SLB4) and found it's specs over here: http://www.panelook.com/LP173WF3-SLB4_LG Display_17.3_LCM_overview_22396.html

And this is the one that the ebay listing "Claims" matches my 8770W.

Also for comparison, here's the actual working TN screen he managed to fit to it that works with it currently: http://www.panelook.com/B173HW02 V1_AUO_17.3_LCM_overview_17335.html Made by AU Optronics.

And here's a side-by-side comparison of both together: http://www.panelook.com/modelcompare.php?ids=17335,22396

They -LOOK- similar in almost every way except one's better specs (The LG). But I have no way to be sure.

So I'm hoping someone that owns an 8770W can come up with some sort of model # of panel that I can hunt down and see if I can match it's specs up to this LG From ebay just to make 100% for sure it will work in this thing.

 

You are on the right track. The panel is for the LP173WF3 family, not certain on the revision though, since it was used in the PremierColor Precisions as well. Ask the seller just to be sure. What you MUST have though are the two cables and the Color Board, which hopefully are left by your friend somewhere in a box, since these are (near) impossible to find. Without them you wont be able able to get the DC running.

 

What triturbo said, plus if the bad screen is retrievable, just get the version/revision code off of it: it consists of four characters that follow LP173WF3. They are most likely (SL)(B3) or (SL)(B4).

 

I think it's not by now, I think it's been thrown away by the shop owner. That's what I'm trying to figure out.... no one out there owns a 8770W with a dreamcolor screen to confirm panel model #? I thought these were fairly popular laptops around that era.

 

You have to pop-it-open in order to get it and you can bet that not a lot of people would do that. All the software can do is read the generic name (LGDxxxx), which wont be of any help for you.

 

I don't believe you when you're trying to tell me software won't read it. Because AIDA64 can easily pull the full model # for the AU Optronics one I have in it right now. And then just paste it into panelook.com and come up with the full specifications.

Anyone that currently has a 8770W with a DreamColor screen can just do the same thing.. grab a free copy of AIDA64, run it, goto display -> Monitor -> And then click it and just type in the make and model # into the thread here.

All I'm actually looking for here is a compatible DreamColor RGB-LED IPS display model # so I can find one for sale, buy it, and have it swapped into my unit.

I'm sure someone somewhere knows this information or can help me figure it out.. And we don't have to rip apart our computers to know.

 

I just now downloaded AIDA64. It identifies the 8740w's DreamColor screen only as LGD0270, beside Monitor ID---beside Monitor Name appears only "Generic PnP Monitor [NoDB]"---I think that it may be up to each manufacturer whether to fill in Monitor Name on the firmware.

 

Well thanks for trying... *sigh* I guess I'm totally boned and forever doomed to a TN screen then. I can't buy near $200 on a panel for this laptop unless I can know 100% for certain it'll work with it......... and apparently I have no way to find out if what I would buy would be compatible or not.

I guess at this point I give up and accept my fate of the TN screen forever then.

Unless someone out there some how knows what the original part # for the original 1080p 17.3" DreamColor screen was for these laptops.

 

This is exactly what I meant. Don't know the exact reason behind this decision, but you can't get the manufacturer P/N via software. The only way is to pry-it-open. Check this thread if someone in there mentioned the exact P/N as I don't remember and don't have time to dig. You haven't answered whether or not you still have the cables and the Color Board. It is pointless to waste your time if you don't have them.

 

You don't know me so well so.. I have no obligations during the days (no school no job, no work) and often sit around playing games. So I have literally nothing but time. I spent 6 hours today digging up drivers for an old PowerVR video card from the deep bowels of "Internet Past" from archived webpages that no longer exist. I'll dig through that thread tomorrow.

But No. I do not know what the "color boards" are. The shop that replaced my screen didn't mention any of that. He did offer to let me have the old dead screen... (which I didn't know at the time I would need or want.. so declined, stupidly.. ) And when I saw it in his shop it was just the panel with some ribbon cables hanging off the back and didn't look to have any "color board" with it. I didn't look closely to see that the screen I had was TN or IPS at the time, I just checked it worked and then took it and left. I only found out about TN and not-dreamcolor after a couple weeks of watching and being all "This doesn't look right." And then dug into it and realized.. no more dreamcolor. By then (now 4 and a half weeks later) I'm quite certain the shop has disposed of my old dead panel and anything attached to it. I guess I might could text-message the owner and ask if he kept anything or if he knows about getting a "color board" for the IPS panels for my laptop. I'm reluctant to do that just yet though.

I've asked one other friend of mine that's an actual electrical engineer for a living and he's told me all LVDS panels in laptops should have the same connector, it's supposedly standardized today.

 

Color Board is that - a board. It's a small PCB with a chip on it standing on the back of the display and two sets of cables go from the motherboard into it and from it to the display. As I said in my very first post in this thread - you NEED them. They are unique for the DreamColor systems and are (near) impossible to find.

I don't give a damn what someone does for a living, all I care is if (s)he is using facts. The facts is that your friend doesn't know better. Let me explain it to you - from the motherboard to the ColorBoard using the first cable set the connection is DisplayPort (different from the stock LVDS obviously, so you CAN'T use you current cable), the ColorBoard stores the panel's settings and also converts the DisplayPort signal into LVDS which then goes through the second cable set to the display.

 

triturbo definitely knows what he is talking about here. The color board is small---you just may have not noticed it. [Edit, correcting that I had forgotten that I was showing the cables/board kit for the 8740w instead of for the 8770w:] The cables and board for the 8740w, very similar to those for the 8770w, are pictured in this post:

or as linked in expanded form:

Any shop person worth his or her salt would know that the cables and board are re-sellable, so very well may have kept them, so you owe it to yourself to ask.

Some potentially good news for you (especially if you recover the cables and board!): the correct version of the screen for the 8770w is the (SL)(B3). At this webpage:

https://www.zhihu.com/question/37569017 ,

or as translated by Google:

a user of the 8770w has posted three screenshots, using the software of the colorimeter Spyder4ELITE, and showing that the software somehow reads the actual precise name of the screen: LG LP173WF-SLB3 151030. The poster also gives this information:

LP173WF3-SLB2 (8760w)
LP173WF3-SLB3 (8770w)
LP173WF3-SLB4 (Zbook17) .

By the way, I would not be surprised if these three screens turn out to be completely interchangeable among the three computer models.

 

I actually dug through some old logs where I was discussing it with a friend of mine and when I first got the thing I had discussed the panel with my friend on a muck.. and this is the model # that AIDA64 had given me, so I found this at least: LG Phillips LP173WF1-TLBS

That's the original one it originally came with and was dreamcolor, I think. I can't find anything on that searching online though.

Thanks for all the other information, asking shop if it had the colorboard and if they have it.

I just finished a short text conversation with the guy that owns the shop I had the repair done at. They said he doesn't remember if it had a colorboard or not but they recycled my old panel long ago. So I'm on my own now.

Also @triturbo: Sorry.. didn't mean to insult you or anything. I didn't know about the colorboard thing and I'm still learning how these HP's go together. I found someone from china on ebay selling a LP173WF3-SLB3 but no colorboard, so no point unless I can find one. I don't guess someone might some how know the part # for that too?

 

If your original panel was from the LP173WF1 family, it wasn't DreamColor, it was high-gamut display however. The spec sheets say that both your previous and your current displays have the same color reproduction. That's spec sheets though, the reality is always a bit different, hence I prefer LG panels for my builds. With that said, the repair guy used the same cable that was already in the system, since both are LVDS, so there weren't left-overs. If you really want DreamColor, you'll have to find the whole assembly.

No worries.

 

It is really hard to find stdp8028 and 2 lvds cable. :/ I only need motherboard dc lvds and I has been year I could not find it.

Better find DC panel and switch it.
