Clevo P775DMx & P870DMx screen upgrade challenge: Chi Mei N173HHE-G32

What's up NBR?

As the title says, this is interesting me to no end. I want to find out if it works.

Does anyone have specs for the N173HHE-G32 from Chi Mei? Generally size and mounting orientation information? See, it's not 25ms like the AUO 1080p screen, it *IS* 8-bit colour and gsync for those who prefer it, with 75%+ Adobe RGB without calibration and possibly more with calibration. It doesn't have the banding issue that the AUO B173QTN01.0 has, and has better colours by a good deal.

So, can this panel slot in? Does anyone know if the lid on the GT73VR is the same as the GT72 (which has a lid that can fit the B173HAN01.2, B173QTN01.0, B173ZAN01.0, and LP173WF4-SPD1/-SPF1) which would mean it's essentially hot swappable?

And is anyone willing to try and find a Chi Mei panel to try swapping it in/out?

The P775DM, P775DM1 and P870DM also should be capable of fitting the panels the P775DM2, P775DM3, P870DM2 and P870DM3 can handle, so if you have one of those and are willing to test, that'd be awesome.

 

I can give it a shot, if you can find me a good source to buy one from.

AFA the mounting holes go, they seem pretty similar.

 

Well... here's one http://www.rit.hk/product/N173HHE_G32-en.html

But I don't know how reliable it is. I've seen a couple other places that show it as "discontinued" which is basically impossible; they're probably just not selling to places other than MSI much.

http://ubbcentral.com/store/item/N1...3-FHD-Laptop-Display-1080P-_191978695059.html is also sketchy.

And finally, plain old ebay that's expensive: http://www.ebay.co.uk/itm/N173HHE-G...r-17-3-FHD-Laptop-Display-1080P-/191978695059

 

I found a listing on eBay with shipping from Texas for $155. Might give that a shot next week.

Do you know if these use the 40 pin Edp or 30 pin?

 

I think they all use the same eDP 30-pin revision.

 

do you know what screen I can use if I want it to be 4K?

The AUO B173ZAN01.0 can... But this is offered by resellers, so there's no point in checking compatibility with it. The Chi Mei is a screen used in the MSI models but it's about the best laptop screen for gamers now.

They are 40 pins and are straight swap. Read more here (RU), the user s-groups2013 did the other way around 120Hz (N173HHE-G32) -> 4K (B173ZAN01.0), but returned to the 120Hz (N173HHE-G32) for reasons stated in the thread.

 

it's 40-pin? Interesting. I wonder why I felt it was 30-pin? I know last gen was 30-pin or 50-pin. Either way, nice find here. Thanks!

 

I was also thinking in upgrading my current 60 Hz 25ms FHD panel to a 120 Hz 5ms FHD panel and N173HHE-G32 seems to be the only option. How does G-Sync actually works? Would G-Sync work with this panel in a Clevo machine? Or there is a list in the G-Sync license implemented in the VGA and with a Clevo VGA G-Sync option would not be enabled ?

 

Well most of the pins go for data and powering the on-board processor (~26 pins), the rest for backlight power and control.

 

Sweet! This will save so much trouble. Just gotta pop the bezel off

 

It will certainly need a Prema mod to work. If you bought Gsync though, Prema agrees that you should get it even with a panel upgrade if it's supported. But that requires getting a Prema mod in the first place.

I would assume, until then, that you won't have access to Gsync.

 

Well, since I currently have 30 pin eDP cable, I will probably pass on an upgrade as of yet, despite being the 120 Hz FHD 5 ms panel far superiour compared to the default 25ms FHD panel. Too much hassle to change the cable from 30 pin to 40 pin.
At least my upgrade will depend on if my laptop will be found or not.

 

Huh. I wonder what the B173HAN01.2 uses if it's 30 or 40 pin.

 

Probably 30.

 

So we need a cable then?

 

If the system comes with a 40 pin then yeah a 30 pin will be needed. I have 2 with me. XD

 

So uhh... lemme know how that screen works... =D.

 

Too bad the B173HAN01.2 did not get G-Sync certification. Would look about the same as the LG but would feel smoother thanks to the 120 Hz.

 

So the B173HAN01.0 is 30 pin for sure. I'm still trying to see if the 1.2 is 40 or 30.

 

It looks a lot better, actually. 8-bit vs 6-bit for colour, 94% NTSC Gamut (84%+ Adobe RGB by extension), over 100% sRGB, etc. However it's still gonna ghost like crazy. I wish Notebookcheck reviewed one.

 

Let's find out.

@Mr. Fox you had both the B173HAN01.2 and the B173QTN01.0, correct? Were they both 30-pin eDP or was any one 40-pin?

 

Hello, just signed up for this, I recently bought a P870DM3 with the terrible FHD screen, not only ghosting is the issue but backlight viewing angles are bad and worse than any other TN displays.
If that screen use 40pin, any idea where to get the cable?

Thanks.

 

Which FHD? The LG 60Hz or AUO 120Hz?

 

I need the Chi Mei N173HHE-G32 so the 120hz version
I currently have the B173HAN01.2 and it is indeed 30pin, checked it by disassembly.

 

The B173HAN01.0 is a 60Hz panel. I didn't know that this laptop sold with those, or that it was Gsync-certified?

 

Sorry corrected, its v1.2 and no gsync

 

Ah. That's the one I was planning to get. But I knew it was gonna ghost, I'm so sad T_T.

I want the Chi Mei. I'ma ask Eurocom if they have it and would put it in as a special order xD

 

But the question still remains with the N173HHE-G32 will G-Sync work with a Clevo laptop? Is there a list for accepted screens in the Clevo BIOS/vBIOS or the BIOS only has the license for the NVidia driver and the list of accepted screens is in the NVidia driver itself ?
Not to mention will even the system BIOS recognize the screen and if it does, will it even allow 120 Hz to be enabled ?
Too many questions ...

@ D2 Ultima I don't wish to ruin Eurocom's business but it would be cheaper to just grab it off Ebay, Eurocom would ask more than double of the Ebay price. A guy in Texas have 10 screens for sale. But need to check first if that is an original screen or a Chinese "compatible" copy.

I myself would buy one for science and stuff, but as of now there is no telling what will happen to my P775DM3-G so I can not jump into purchases like this ...

 

I've seen laptops that have G-sync screens without g-sync support. Guess the display work normally without gsync.
Also compatible with some edp to dp converters.

 

Remember, for Gsync to work on an internal LCD, you need three components:
The BIOS must be gsync capable.
The LCD must be gsync capable.
The GPU must be gsync with it containing the device id of the installed gsync LCD.

If one of these components is missing, you'll still have a working internal display. It just won't be able to use gsync within the OS.

 

I personally don't care about having g-sync or not at this point, looking for the alternative for this inappropriate display.
I would go with the 1440p display, but i'm afraid the green banding will be kinda visible in gray shades, plus 1080p is already perfect for 17 inch and equivalent at the same distance of a 28 inch 4k screen in pixel size. Don't want to use windows scaling.

 

I think at 17" on a laptop, choosing between a FHD and QHD is subjective, and someone should choose what they feel is best. In regards to the banding in the QHD, that issue may be a bit overblown. For example, IIRC @Phoenix had nothing but high praise for his QHD display.

Now QFHD at 17"... I think at this point in time with current scaling technology, it would best be left to those who have the eyes of an eagle or hawk.

 

I've seen banding IRL, its certainly visible if you use the display everyday. Especially if you try another display and go back.
Didn't say QHD isn't appropriate for 17 inch, and didn't generalize. Just prefer to get that screen with the better quality over the extra pixels which is overall respectable at 17 inch (on this specific laptop..), I would argue if it were 24-28 inch display though.

 

It's not that it's really overblown, it's actually a bit underblown. A lot of people claim it isn't visible but AUO acknowledge that it's a problem, for example. I, personally, know it will drive me NUTS. I also know, that the 1440p screen is extremely low quality. It's only around 54% aRGB and 85% sRGB. That's pretty damn low. It also isn't true 8-bit colour from what I remember, and its banding is probably from the dithering at 8-bit (though I haven't gotten someone to really check).

It also has bad response times for a TN panel; 10ms average for B2W (outside of 120Hz range) and ~29ms average for G2G, and PWM has been detected on one panel that NBC analyzed. All in all, it's a screen I don't want. I'd rather take a ghosting screen that has great colours and no banding and everything, however I still would rather a screen with good colours and little to no ghosting =D

 

It would require a Prema mod, but I don't have the money to afford gsync on my upcoming machine I think. So... I just would want it for the basics. Would like to try gsync one day, but I guess this is not the time.

 

So @bloodhawk how's that screen coming =D

 

Got super busy with work, and forgot to order. Then "accidentally" ordered a DM2/KM1 , waiting on that now

 

luuuuul

 

I'm in the same boat as you.

Do yourself a favor, try and take a look at the display panel on the ASUS ROG G701VI-XS72K.

The panel is a 17.3", 1920 x 1080 120hz G-Sync screen that differs from the Chi Mei N173HHE-G32 because it also happens to be IPS.

The problem is I can't find the model # for the panel, nor can I find any specs on the response time or color gamut. I'm assuming that it would be just like the Chi Mei, but with worse response time but better colors, contrast and viewing angles from being IPS.

Worth a look see.

 

without a shadow of a doubt, it is the B173HAN01.1 panel. It's the only 120Hz 1080p IPS Gsync panel.

 

Good call, but that's weird because the B173HAN01.1 is an AUO panel while the one listed for the Asus Rog on HIDevolution says it's made by LG (no model#)

Could be a typo/mistake, i'll try and dig around to see if LG makes anything like that. Asus' website is crap for looking for specs.

 

LG? 120Hz? IPS? Gsync?

@Prema you have any idea what panel this could be?

Also, ASUS doesn't know a single thing about their laptops unless you have a serial number. I'm not even kidding.

 

You ain't kidding about ASUS...it's horrible. Here's a screencap from HIDevolution. It's all I can dig up. I might shoot them an email or live chat tomorrow just to find out.

 

I once called ASUS, gave them the model number of their laptop, and asked them what the screen was. They literally told me they don't know unless I have a serial number. I told them the laptop only comes with one panel. They told me they need the serial number to know what is in the laptop. It doesn't matter if it only comes with one screen... without that serial number, they don't know what screen they put into it. It was the most retarded thing I've ever experienced.

@Donald@HIDevolution do you think you can tell me what panel this is? The ASUS 120Hz 1080p 17" LG one that is gsync?

 

What model number?

 

http://www.hidevolution.com/asus-g701vi-xs72k.html

This one, the G701VI-XS72K (also the G701VI-XB72K). Thanks in advance!

 

It is the AUO B173HAN01.1 120Hz screen for both models.

 

It says LG though on your page. Is it a typo or did ASUS screw up yet again? And thanks for checking!
