Dell Inspirion 7577

EDIT:
This post does not appear to be viable for most people who ordered the FHD 7577 and want to upgrade to UHD. The info presented here is still useful for those who ordered the UHD model and wish to upgrade their stock panel to the next level. As always though, please compare data spec sheets on panelook.com between your stock panel and prospective upgrade you are looking to swap in.

YOU HAVE BEEN WARNED!

For anyone interested in a UHD panel swap or upgrade, here are the top choices sorted by brightness:


The first two Sharp screens are 100% gamut with best brightness to boot, but have a few thousand fewer hours of rated life. The brightest panel also has 30ms response time compared to the 25ms response time of the 2nd brightest Sharp panel.

Here is the second brightest Sharp panel specs:


Here is the best contrast screen with same brightness as stock UHD Dell 7577 screen (300) and equivalent gamut coverage (72%) but 5ms slower response time (30ms vs the stock UHD at 25ms):


Imo the Sharp screens win in the UHD category. Their perimeter bezeling makes their total physical size about 10mm wider and 6mm shorter than the stock UHD panel though, so some minor dremeling or plastic modifications may be needed in addition to adding your own mounting tabs with some thin sheet metal and epoxy... or you could just glue or double stick tape the panel in place possibly.

Here is the Sharp screen on Newegg (although I don't know if I would trust the seller in particular):
It looks like the Dell MSRP price for this panel is around $600-700, but it can be found by a lot of sellers elsewhere for less than $200, however I am not sure as to the authenticity of manufacturer...

Here is an NBR thread discussing the Sharp panel:
http://forum.notebookreview.com/threads/gs63vr-1080p-panel-switch-to-4k-igzo.796584/

Other considerations:
The Sharp panel is " IGZO TFT-LCD, LCM " type.

The stock AUO panel is " a-Si TFT-LCD, LCM " type.

The mounting ears on the Sharp panel stick out to the left and right rather than top and bottom which may be where the difference in listed total physical dimension specs come from on the panellook.com specs, but the active areas are the same. Worst case scenario the ears may need to be either be cut off or some plastic removed on the case halves to accomodate them (if you don't feel like cutting them off) in addition to adding additional mounting ears to the top and bottom positions where the stock panel has them... or just use glue for mounting.

 

Sorry for the massive pics, but I tried editing the post and keep getting a weird error I haven't seen before...

 

I wonder if they use different cables (6 vs 8 bit).

 

so your preference would be 7567? I'm sorry for my bad english.

 

So I had to jump through a few hoops on panelook.com but I was curious myself and wanted to see an actual panel datasheet. I registered a free account using my usual gmail account, but then before I could download I had to verify my "business" email which can't be gmail or any mainstream email I guess. So I used my school email account and it worked, lol. It got me 50 pcoins or some **** and the download cost me 30 pcoins... go figure. But I love data sheets with real info. Honestly I could've just based the 6 bit vs 8 bit argument on color depth alone (FHD 2 lane eDP @ 6-bit = 262K colors || UHD 4 lane eDP @ 8-bit = 16.7M colors), not to mention the specs details page specifies 6 bit for the closest model number to your panel.



The PDF datasheet is attached to this post as well.

 

Sorry I guess I should have said that I wonder if the FHD model comes with a 6 bit cable vs the 8 bit in the UHD. I'm not sure what all would be required to go from FHD to UHD aside from the panel itself.

 

Here is the details and spec sheet PDF for the closest UHD model number to my panel:


BTW in case you want to pull any data sheets for yourself, Protonmail works to verify a "business" account.

EDIT:
Based on the significant pinout differences, I would assume your 6-bit machine has a different mobo part number... If only we could get a part number from Dell for the FHD vs UHD mobos. I suppose the next best option would be to look in AIDA64 Engineering Edition to get more info on the mobo model number
and see what we can find on the internet?

 

Right, but what cable comes in the FHD 7577?

 

See my edit above as well as previous panel topic posts. The FHD vs UHD panel cable differences are 30pin vs 40pin respectively on the panel end of the cable, but it is really the motherboard end that is the bigger concern.

Everyone else considering going out on a limb with unverified panel upgrades, I would highly suggest checking the data sheets for your stock panel and the panel being considered, it only takes a bit of fake registration hassle to get your hands on the legitimate specs of a given panel on panelook.com. Based on the significant pinout differences, I have reservations as to whether the FHD to UHD potential upgrade is actually a realistic possiblity.

Best case, the panel swap wouldn't work or wouldn't work correctly... worst case, some critical pins mate to the wrong connections on your motherboard connector and fry some circuits.

Wierd question
Does 7577 has mini pcie slot?

Sent from my Z2 Plus using Tapatalk

 

https://www.pcmag.com/encyclopedia/term/64794/mini-pci-express

The 7567 and 7577 both have m.2 slots in addition to SATA connections for a standard laptop hard drive. The stock NVMe SSD occupies the m.2 slot and the stock HDD (if equipped) occupies the SATA port.

 

I wanted to actually use my old intel 5100 wireless card from dell latitude e6400 due to its linux compatibility. I dont think it will fit on m.2 slot due to different ends.

Wait, is the 7577 also locked into not being able to run linux or whatever that ******** that happened was?

Sent from my Nexus 6P using Tapatalk

 

I dont know but the new intel card used in 7577 cannot go to packet injection mode. So i am relying on my old intel 5100 for that purpose. I dont have my machine right now so cannot confirm.
However few geeks managed to install ubuntu on a 7567. So i think there nothing like we cannot boot linux in these machines.

Sent from my Z2 Plus using Tapatalk

 

Which ubuntu version are you talking about?
Give the linux firmware 1.164.x a try. https://launchpad.net/ubuntu/+source/linux-firmware
I hope you know how to install the deb package via Gdebi or synaptic package manager. I also recommend using Linux HWE tweak to download latest kernels either 44.11/4.13. Use 16.04 to best performance.

 

What are you talking about? The Dell user manual lists Linux as a supported O/S...

@vibhawa the mPCIe standard is physically larger than the m.2 standard but the underlying communication protocol should be the same. If you really wanted to I'm sure you could rig up an adapter of some kind but it wouldn't be discrete or convenient by any means.

You're better off just buying a compatible external USB-based plug in WiFi module that has the driver options and control you need.

EDIT:

Look here for more discussion:

And here for an adapter example:

Thanks for the adapter.
I guess an external wireless card is a better option.
Finally my Intel 5100 will retire after 7 years.

Hi everybody, I received the Dell 7577 3 weeks ago. It is my first Dell and Its awesome, great temp compared to my old Vaio F136. But is there anyway i can adjust the screen color? it is pretty bad

Does Dell have "battery care" function? The battery stop charging at 80% to reserve charge cycle ==> longer battery lifespan. My old Vaio has this function.

 

I think you right click on the desktop and you will see intel video controller there. If I remember correctly.

 

Dell uses QuickSet app to set charge thresholds.For screen calibration I'd check this site and see if you have similar screen model described here https://www.notebookcheck.net/Dell-...HQ-GTX-1060-Max-Q-Laptop-Review.264134.0.html

 

I just confirmed, on my Inspiron you right click the desktop, and then there is intel graphics settings button. You can go in there and adjust your display color settings etc.

 

Not that color settings but the feature to set color profiles aka calibrated icc files optimised for photo,video editing or that guarantee full sRGB or RGB coverage for our specific monitor.

 

Dell Power Manager can control your charge thresholds. There are also some settings for charging in the BIOS as well. This stuff is all in the user manual, or a quick Google or forum search away.

The iGPU is considered the master GPU and where you go into settings to adjust your screen colors, etc. Look under your Intel control panel. There are multiple ways to access it.

 

I have a spider for that. CLip it onto your monitor, and load the software...it automatically adjusts to Whatever profile you want to use. However, the person asked about adjusting the color etc on his monitor...I told him how.

 

Hello Vasudev, regarding the screen colors, it seems that a good way way to solve the issue is to replace the screen, as the basic one has really low color accuracy. Our friend Polihedron found a way to do in page 46 of this thread, you can refer to it.

 

Finally playing around with this other 7577 that I received. Sadly it doesn't undervolt as well as the first (this one will do -125mv where the other did -165mv) and it came with the slower toshiba vs the PM961 the first had. Over all however it's running nice and cool while doing prime95. I may repaste it just for fun though. The new Samsung PLS screen should be here in a couple of days so we will see how that looks (I'll try to get before and after pictures).

 

Oh thank you, that is what I'm looking for. I mainly use this laptop on AC power and this Dell Power Manager app has this mode

Oh well, what I need is the icc profile and also how to add it . My IPS panel this 156WF6-4XK13 and I'm considering to buy display profiles since I found this site sells them for $5 each and $10 for all 3modes. Is there any suggestion for me?
http://laptopmedia.com/review/dell-inspiron-15-7577-gtx-1060-max-q-review-improved-but-still-flawed/

I also found that the camera sensor has poor "auto white balance". It produces "more yellow" image than normal (My room uses 5000k bulb (yellow sun)) , to fix this I manually light it with white flashlight.

Anyway, thank everybody for your kind responses and I'm sorry if my bad English is confusing .
you know the feeling of getting a new laptop after 7 years is awwwwsomme....

 

Nice link you shared, I'm going to add it to my Table of Contents in my dedicated 7577 Thread later tonight:

http://forum.notebookreview.com/thr...-details-pics-of-internals-optimizing.811380/

 

Same configuration as earlier one or other this time?

Sent from my Z2 Plus using Tapatalk

 

Same - i5-7300HQ, 8GB ram (upgraded to 16), 256GB SSD (upgraded with my 1TB PM961). I would totally do an i7 but the 300 bucks more is crazy to me.

 

I'm hoping my replacement machine undervolts better than my last one that struggled achieving -100mv to -125mv even.

I didn't realize until recently there was such a big performance difference between the Toshiba and Samsung SSDs. I am hoping for a Samsung, but won't hold my breath considering what I've read on the matter. It sounds like Dell originally intended the Samsung drive to be the spec, but are having supply issues. What a shame for us the difference in performance is such a wide Delta.

What are the numbers you consider "nice and cool"?

 

Running Prime95 for the past 12 hours, the CPU has kept under 70C.

 

Since you are having same cpu as the previous one then why no undervolting possible to that level that you did in your previous 7577?
Can you throw some more light over this?
Thanks

Every CPU is different in how good the chip performs. My first one was a total rockstar and could probably have even gone more than -165. This one is pretty mediocre at -125mv. The 7300hq in my XPS would do -155 easy.

This is why Intel runs so much voltage through their chips to begin with. Since there is a big variability in how they perform they add extra voltage to make up for that.

 

What @custom90gt said above is spot on and it's also what people here on the forums and elsewhere refer to as "The Silicon Lottery". Not all chips are made equal basically.

 

Then your method of setting color profile works. Without spyder and displaycal it is simply not possible to accurately calibrate the screen.

Sorry, I wasn't the one affected by screen issue.

Some time ago I used Dell quickset to set charge threshold, it seems they created Dell power manager app.
See this link for calibrated screen profile. https://www.reddit.com/r/Dell/comments/6takls/just_color_calibrated_my_inspiron_7567_ips/
Use DisplayCal or windows calibrated tool to apply the color profile globally.

 

How do you decide which one you would buy? I checked panelook. They don't give information about cable length or connector position. Did you just see the picture provided by the website?
BTW, nice link you got there. That link practically solve inspiron 7577 owners problem regarding the average gamut coverage screen. Its just too bad the website don't do sorting based on screen refresh rate

 

I looked at the picture provided. I also cross checked to see what the guys with the 7559 were doing since they use the same panel layout.

Panelook will let you customize what to display if you click on the gear. You can show the panel's refresh rate (frequency).

 

Read pages 47-51 from this thread for a good screen upgrade discussion. There are additional bits of information if you read this entire thread or use the search function as well.

You can add that info to your teardown/upgrade thread.

Yes it's on my list to add, just haven't gotten a chance to with my life being so busy all the time and the holidays here. My wife yells at me for spending too much time on the computer now that the semester is over and I don't have to be glued to it 24/7. We still haven't even gotten to decorate our Christmas tree yet, lol.

 

So I just swapped out the screen on my 7577 and I am happy with the results. I did take some pictures with my cell but I don't think they do it justice. The colors are so much more vivid and the brightness is way better. It took me ~20 minutes to swap it and that includes taking all of the photos and such, not hard at all (I've done a lot of them before so it may take you a bit longer). Always remember, slow is smooth and smooth is fast...

Here are some pictures:

Stock screen 100% brightness:


Stock screen 50% brightness:


Bezel removed:


Samsung LTN156HL01 100% brightness:


Samsung LTN156HL01 50% brightness:


I probably should have found a more dynamic or colorful background for the pictures, and I should have used my T6i, but I am lazy and was excited to get the screen installed...

I should also mention that before I swapped I really preferred my XPS screen to the 7577. After the switch, I think the samsung takes the cake.

 

If you guys have questions about the screen swap let me know. I found that on this bezel the easiest way to do it was with my finger on the sides and an old gift card along the top and bottom (coming from the outside in if that makes sense). I have been using my 7577 a lot more since replacing the screen. The colors are as good as my U3415W. Even if I get a new XPS in the future I may swap that screen into it, lol...

 

I keep old gift cards and hotel key cards for all kinds of reasons, they come in handy for certain things. I used to travel and live out of hotels almost exclusively so I have a ton, lol.

 

anyone playing PUBG on this laptop ? (i7700hq+1060mq)?

after big patch PUBG yesterday, how well this laptop perform in game(FPS and temperature) ?

 

Re: PUBG
My brother has played it on his for a while has had no problems, plugged in or unplugged, since day 1 and including today

I am looking to try to find a way to instrument the CPU and GPU. I have tried a lot of the typical recommendations, and either I am not smart enough to configure it, or they are not able to find the temperatures. I know that Unigine is able to get the temperatures, and also frequency of the GPU. I cannot figure out how to get both outside of that program.

Can someone detail some fairly specific steps on how to replicate something that allows for an overlay in an application of the GPU and CPU temperature (+ more?)

 

PUBG has massive patch yesterday its no more early acces, its optimize game now,

would you mind to monitoring THE CPU and GPU temperature while your brother playing with msi afterburner, or HWmonitor please? and how many FPS on medium / high setting.

 

Install MSI Afterburner and it should also install RIVA Statistics Tuner. Riva Tuner can overlay the hardware info in real-time over any game. It can be configured pretty well too. Render style (font basically), color, location, and size can be set to your liking. You can also use a toggle key to turn the overlay on/off, etc. I believe it's capable of showing most of the stats that Afterburner graphs and monitors in real-time. They work together and need to be configured mutually. There's probably more help on the Google or if you search this forum in case you get stuck.

 

Hi All!
Got my 7577 a couple of days ago and really pleased with it so far
Spec I got: i7-7700HQ, 16GB RAM, 1060 Max-Q, 256GB M.2 + 1TB HDD

It was a great deal on the Dell online store, currently offering 12% off so it was £1256 including a FREE Dell Visor VR/Mixed reality headset & controller bundle. The laptop turned up next day which was a surprise, but I'm still awaiting the Dell Visor.

I was worried about the red keys and backlighting, but when mine turned up it has white keys & backlighting with only a small red bezel around the track pad! So very pleased with that

I've overclocked the GPU by +200 on the core and +250 memory clock.
My fire Strike result is: 9425

I plan on getting these next: https://www.scan.co.uk/products/16g...-19200-(2400)-non-ecc-unbuffered-cas-16-1?v=b
as currently mine only has a 16GB stick, so only running in single channel. I'll sell the current single stick which should offset some of the cost...

Quality wise, I'm so impressed by it! I'm upgrading from the 7567, and much prefer the plastic and metal of this laptop rather than the soft touch stuff on the 7567

I know a lot of people hate the screen on the 7577, but compared to the TN display of my 7567 its a revelation! So I'm happy with it.
I have a small amount of backlight bleed just to the left of the webcam, but if I give the bezel above it a gentle squeeze it goes away, so not bothered by it.

So there we go, just my thoughts so far

Cant wait for the VR to turn up!!!

 

I have been loving my 7577 so far. I have been playing with MSI Afterburner and Kombustor trying to find a good OC tune. Default Kombustor settings is about 84fps. I can crank the core clock to about +200, which gets me about 86fps. But to my surprise I get better FPS by "reducing" the MemClock to about -300 which gets me to 90fps. "Increasing" the memclock by 300 bring the FPS back down to 84ish. Anyone know what is going on?
