Dell Inspirion 7577

I told the guy I've been without it for long enough and that I was issued next day shipping on the initial order but he kept saying he couldn't expedite the shipping on my replacement machine... Idk who you guys are dealing with but the guy I talked to today was at a call center in the Philippines.... If the keyboard is on backorder I wonder how the orders themselves are not delayed... I'm pretty sad I won't have my new laptop I ordered Oct 31st back by next week after this semester of school is over... It's been a long semester and I want to play during the small amount of time I have off before next semester starts up.

 

Make sure that new system comes with a new warranty - it would be bogus to not have a full warranty on it.

 

I was about to say the same, it will take further fighting to get this as well as I have had the same happen.

I too would like to confirm that my laptop has bleed in the top middle of the screen but it's not as big as some of the ones posted here thankfully. @malek48 i do hope you get your new laptop asap. Dell Support sounds horrible and I hope to never deal with them.

 

Hi guys, it's my first post here, I would like to share some of my experience regarding to backlight bleeding screen.
When I replaced display in my Dell 7577 to LG LP156WF6-SPB1 I noticed that I don't have backlight bleeding until I put the front screen cover back on. It looks like plastic latches around that cover make internal border of that frame pushing a bit too close to the display. So, maybe if you take off front cover, and try to bend latches a bit, or modify one, or two by cutting edge of the latch, then I hope you will fix backlight bleeding screen.

 

I'm curious what your reasoning for swapping out the dell IPS for the LG is? Better response times?

 

Ordered a 7577 today, will let you guys know how it turns out.

I Didint get a answer before so I'll ask again.
Anyone used a 120hz panel and if so which one.
Been thinking of using a AUO but I hear that's stuck in max brightness, hear the chi mei is good but nobody seems to talk about how it is on other laptops.

 

Not planning on sticking a 120Hz panel in mine, sorry.

 

I plan on do that in the distant future to breath some life into the machine later down the line, so for me we are talking I a year maybe two. Until then I probably can not help you

I went with the base model so things like getting some more storage comes first.

I'm using my Dell also for dslr camera raw photo processing, and I didn't liked my photos when I saw them on the original LG LP156WF6-SPM3 display, there was huge difference in vibrance and saturation, especially for greens and reds. I found local store in Europe, with exact display model for a good price, ordered it, replaced, and I'm happy now.

 

I agree with you the greens and reds are quite bad on the FHD screen. I was a bit surprised when I compared with my old laptop, even though this was reported in the existing reviews of the 7577. Is it difficult to replace the display when you are a noob like me, who never did this before ? Or did this european store replace the screen ? Could you tell me the name of this store pls ? I am thinking to update the screen as well.

 

Sure, it's easy to replace if you have tools. My favourite is old credit card, or some flat plastic stick to bend front cover a bit, and release the latches. That's the hardest part, you need to be carefull, and do not to bend to much the frame, and avoid pushing the screen. It's good to start from the outer top, any corner, or from innner side left, or right middle point, try to find the weakest point, and start from it. You can try it before ordering.
In my Dell I have to use some medium force to open latches, because they are quite matched. You will need also small philips type screwdriver for 4 screws at the display, and something to open latch at the eDP connector. Quite easy if you have some basic diy skills.
The store is in Prague, LCD Display Shop, you can order from them also replacing service.

Thanks a lot for the information ! This is a good opportunity for a trip in this beautiful city of Prague I will try to contact them and see if we can arrange a replacement. Thanks again and have a nice day

 

I'm glad you like it,
you can also send your laptop, but in my opinion it's a bit risky..
forgot to mention, please check with some LCD testing software your display after replacement, my first recieved display had some thin, visible only on the dark background line issue:

no problems with the second one.

Is that screen better for photo editing? Looking at the specs for the panel it seemed like a fairly low gamut screen but maybe I was looking at the wrong one. How is the brightness on it?

 

Well, I don't have tools to check it, and answer you for sure in numbers, but I can see it, and it's fine for me.
LG LP156WF6-SPB1 is very bright at maximum setting, and colors are great.
I'm not a professional gamer neither professional photografer, I like to play games from time to time, and make some good photos.
I was looking for something like SAMSUNG LTN156HL01-102, or AUO B156HAN01.2 but not from chinese store with no warranty, or logistic trouble if the display panel need to be return to sender. I checked few stores, most of them are selling not the exact models, but cheap replacements.
I think, if I would get samples of those display panels to compare in photo edit, or daily use, then probably it would be for me hard to find the difference.

 

I appreciate the info. Do you mind posting a picture of the connector on the stock screen and stock part number?

 

sorry for the quality, I had around only my washing mashine.

 

wait your washing machine?

 

Do these help at all? As long as the connector pin count and exiting side are the same as the stock lcd screen, there's a decent chance it will work, especially with the amount of bezel space the 7577 has to work with. But I don't think all lcd screens pinouts are standardized unfortunately... I was under the impression the eDP standard was supposed to help alleviate that sort of stuff though.

 

Hey,
that is helpful, thanks! The connector is typically standard however the placement isn't always. I'm curious what the best screen replacement would be for these. I'd really like something that is brighter with better colors. My old sager had what I consider the best screen I've seen in 1080p but I have to figure out what it was and if it would fit...

 

I think the center hinge on the Dell 7577 makes the choice of LCD screen replacement much more flexible in conjunction with the generous bezel and wire routing space available since the exit side can be left or right (as long as it isn't in the far corners, but towards the center a bit). The last time I really looked hard into this topic was on my oddball 14" HP laptop (1366x768) from 2012 which was right around the time the major transition from LVDS to eDP was happening. LVDS had various pin counts and pinouts but I think eDP is more consistent and the primary variable becomes where the connector exits the LCD screen so it can fit within the bezel and have the proper wire routing room through the hinge area to the mobo.

I have a technical link that might help you decide:

http://www.vesa.org/wp-content/uploads/2010/12/DisplayPort-DevCon-Presentation-eDP-Dec-2010-v3.pdf

DISCLAIMER: It is an old technical document and likely outdated by now.

 

Yeah it's really not the connector type I'm worried about, it's the positioning and I just wanted to verify it. The only hard part from here on out is finding the perfect screen, lol.

 

https://www.laptopscreen.com/English/model/Dell/INSPIRON 15 7577/

Try searching for : 15.6" AHVA lcd replacement screen

Size: 15.6-inch WideScreen (13.6" x 7.6")

It looks like as long as you find a 15.6-inch (13.6" x 7.6") screen with 30 pin connector (30 pin = for the FHD // 40 pin = for the UHD) with the position of the output connection correct, it's mostly up to you to decide which manufacturer makes the best quality, high gamut IPS screen that satisfies your visual requirements. I'm not necessarily recommending you buy from the link above, but they do have a nicely formatted set of data to get you in the right ballpark.

 

yes, it's my primary camera

regarding to replacement, even if you get best specs, perfect screen, you don't need to worry about eDP connector placement, you can order the longer wire, and probably you will manage to use free space inside the screen cover.

 

So nobody here used a 120hz panel from chi mei or AUO on this or any other laptop? Was curious since I remember they where stuck on max brightness when you install them and I was wondering if there's a fix for that or if there's a alternative.

 

as far as I know B156HTN05.2 120hz TN panel is working,
and for brightness change, maybe you can use gamma control as an alternative solution?

have you seen this post?
http://forum.notebookreview.com/threads/dell-inspirion-7577.808514/page-19#post-10614149

 

You could try uninstalling the native driver that the screen itself loads and load the old driver manually but you might lose out on the higher refresh function then if you are talking 120Hz panel as the upgrade being put in place of the stock panel... Maybe it is possible to merge two drivers into a single custom driver? This is definitely something I am interested in learning how to do but for now it is way above my head, lol.

 

I too would be interested in a 120hz screen replacement with working brightness control so shoot any info you fellas heather please

A 120Hz TN panel shouldn't be too hard to come by as @polihedron has shown. The IPS panels may be a bit harder to source... Depending on your gamut preferences. I would say there is a good chance that the panels that work in the 7567 will have a decent chance at working in our 7577 machines.

 

I hear the TN panels are almost as good as IPS anyway so I don't see the need to go through the effort.

 

How about this ebay link that sell Lenovo brand of 15.6" AHVA ips screen?

https://www.ebay.com/itm/NEW-15-6-L...A-IPS-PLS-IBM-LENOVO-5D10G16541-/400991261360

Will this match your theory if someone want to use this to replace inspiron 7577 regular ips screen to AHVA ips screen?

 

Based on my personal theory and this practical example of trial and error:

https://www.reddit.com/r/Monitors/comments/6ncfaz/is_there_a_standard_for_edp_connectors_on_screens/

It would appear as though it's a pretty good chance it would work. Don't be pissed off w/me though just in case it doesn't lol.

Also note: sometimes manufacturers use 40 pin cables without all of the pins populated. Cracking open your unit to count the number of pins on the mobo connection might help clarify some things as well.

For example, even if you have a 30pin connector on your lcd screen end, you might have the 40 pin connector where it attaches to your mobo but with only 30 of the 40 pins populated. This keeps things simpler for the manufacturer in some cases and eliminates the need for different mobo part numbers and configurations and/or adapters on the mobo end.

OTHER THINGS TO CONSIDER:

How different is the power draw requirements from stock?

How thick is the physical dimensions compared to stock screen thickness?

How many mounting tabs does the screen have (if any) and are they in the same location as the stock screen mount bracket?

Are in-house panel brands actually renamed/rebadged mainstream-producer panels? (That would be the better case.) Or are they actually being made by the same OEM that's producing the laptops the screens are meant to go into. (This could prove problematic in terms of compatibility and non-standard pinouts.) I mention this because the brand panel you linked to says Lenovo. I'm not exactly sure how many unique lcd screen manufacturers exist in the industry... I know LG, Phillips, Samsung, AUO are all commonly known manufacturers.

Driver issues.

Mobo and/or other hardware conflicts.

I WOULD ALSO:

Try emailing the UK eBay seller you linked to and ask them straight up about some of this stuff. Tell them what you are after and see if they have a specific recommendation for you. Make it clear you don't just want a stock replacement but a custom upgrade. You could even direct them to this thread and encourage them to make an account and post some info answering everybody's questions and reservations so it could be helpful to everyone who wants to go this route in the future and be forever searchable. This is a hot topic on the Dell Inspiron 15" laptops. Not to mention it might potentially drive them some business.

These are the things I think about. My $0.02

 

Okay so since we are on the topic of displays would anyone mins explaining to me what we'd be losing out on if we take a screen without gsync. Would it even be possible to find a 120hz IPS/high quality TN display that's gsync?

It sounds like it's mostly a driver limitation more than anything according to that post.

Gsync requirements ala NBR thread:

This NBR thread brings us full circle back to custom BIOS flashing:
http://forum.notebookreview.com/threads/g-sync-query.809526/

FINAL THOUGHTS:
Yes, it could technically be possible with a lot of deep knowledge in multiple areas of low level computing but on a mid-level machine like ours it wouldn't seem very worth the time, hassle, and risk. Unless you're into that sort of thing.

It ultimately boils down to paying whatever premium the OEM and hardware manufacturers demand for the extra few lines of code in the driver and BIOS in addition to whatever it costs them to license the adaptive sync moniker from either AMD (FreeSync) or NVIDIA (Gsync). DRM bull_shit at its finest holding back better user experience and/or performance on the same exact hardware basically. All in the name of more profits for already insanely profitable companies... Murika!

MyDigitalLife forums have tons of great BIOS modding resources if you spend the time to learn the trade.

 

Try a request thread at www.bios-mods.com for custom bios instead of doing your own.
There are experts and modding your own bios have chances of bricking if something goes wrong.
Try there, guys there are best at custom bios.

Hi guys. I live in turkey. The 7577 is new here. It came out with 1050ti graphics card. should I choose this instead of 7567? Both are sold at almost the same price. which one should you choose? 7567 is very popular in Turkey now. But I can't find 7577 user. your views are very valuable to me. Thanks.

Dell Inspiron 7577 i7-7700HQ GTX1050TI 8GB 1TB+128SSD FHD 15.6 Linux(IPS) 929$ or;
Dell Inspiron 7567 i7-7700HQ GTX1050TI 16GB 1TB+128SSD FHD 15.6 FreeDos (IPS) 989$

 

Well considering they have the same GPU I would go with the 7567. It has a bigger battery than the 7577 and the extra ram is worth the $60 in my opinion. Just make sure it's not a terrible TN screen...

 

So this morning I did a little research into the panel on the 7577 (lp156wf6-spm3) and am kind of shocked.

Here are the specs: IPS, Wideview 200nit brightness 600:1contrast rario, 45%NTSC color gamut

Notebookcheck test showed that it covers 55% of the sRGB spectrum. Not very good specs, in fact pretty terrible.

The LP156WF6-SPB1 that polihedron is using is at least 72%NTSC and 300nit brightness with a decent response time.

Looking at a ton of different reviews on notebookcheck and such here are the three screens I'm deciding between:

LG LP156WF6-SPB1
AU Optronics B156HAN01.2
Samsung LTN156HL01-102

Seems like they all have great colors with the samsung being the best however prices may differ a bit.

Another great option may be the LTN156HL06-C01 since it has a wider range of colors however finding one seems to be difficult.

If my XPS ever sells I'll buy a screen for the 7577, lol.

 

Just curious where you are pulling your specs from so others know where to look as well.

My UHD screen hardware model number is in my signature below and has very little solid info to be referenced on it online unlike the FHD options.

One of the links I posted earlier showed a before and after that was very obvious as to the improvement of the washed out colors.

Part of the reason I got the UHD screen was for its better brightness and color qualities than the FHD in addition to having more scaling options and text clarity when coding.

P.S.) @custom90gt wasn't there a guy looking for an XPS a little while back that I shouted you out to help make the connection? Or was it a 7577 he was looking for?

 

I sourced my specs from a lot of different places. I like notebookcheck because they often use a calibrator to check the actual color response from the panel.

Another great source is http://www.panelook.com/sizmodlist....esolution_pixels=8180&signal_type_category=70

That lets you sort by color and all whole bunch of stuff

I ended up ordering a genuine LTN156HL01-101 for really cheap on ebay (hard to find genuine panels). It's a pull from a Asus Q501L that was "tested" so I hope it is in good shape.

I really like the UHD screens, but I couldn't swing it price wise...

Also that guy that was looking for solutions to his XPS throttling ended up just being a dell power manager setting. Everyone was pointing at VRM but no one actually tried to troubleshoot it so I helped him.

 

Ah, yes now I remember that XPS throttling thread. My memory is ****, lol.

I really wish someone would take some hard numbers on my screen model so I could know what I ended up with.

I sent an angry email to the Dell manager yesterday to light a fire under their ass and the case manager actually responded in a matter of hours saying he would be doing his best to make it happen.

I used @GoNz0 and your input to help create my email with some extra leverage and demanded the full 12 month standard warranty period in writing as a requirement on their part.

So I guess we will see in the next week or so what ends up happening. I told them I was tired of waiting and want my machine by the end of next week at the latest... AKA before Christmas damn it. Tonight is my last final for this semester. So excited to have a month off, but pissed I don't have my replacement machine yet. (-_-)

I was pretty impressed with that UK eBay seller's selection and organization of panels, but I'm not sure if their prices were good and their search and filter system does kind of suck on the eBay platform.

EDIT:

Also, to the guy in Turkey asking which Dell Inspiron to buy, doesn't the 7577 have a superior thermal handling system to the 7567?

 

I'm sure your panel is awesome, the 4k panels that I have had in the 9550 were amazing screens.

One of these is likely your screen:
www.panelook.com/modelsearch.php?keyword=B156ZAN

I still can't believe you don't have any word on your laptop. I ordered my wife a new inspiron 13 7373 from dell monday night and I received it yesterday...

 

I had the same list, and the LTN156HL06-C01 was on the top, until I visit the blog of the guys from some lcd store:

https://screen4less.blogspot.com/2017/08/ltn156hl06-c01-people-please-stop.html

I hope you will like Samsung panel

 

Interesting that they posted that. I swear I saw a few people running it in their 7559 laptops even with the 6-bit cable. Oh well you can't find any genuine C01's anyway.

 

if they are using 6bit cable then it's not an 16.2M, 8bit Color Depth parameter display, but 262K, and I'm wondering how it's possible.
Display is probably not genuine, it looks like chinese sellers are cheating on us.;D

 

Yeah I dunno, I just saw people doing that.

I also recommend anyone buying a screen to look at the pictures to ensure they are genuine. The LG and Samsung displays are "compatible" versions most of the time - aka cheap panels that would likely not be a decent replacement.
