Dell 17r N7720 SE - user review

Yep i got this ID in device manager, screen is great and i dont have even that model with 3D.

 

Thanks for the reply in my post on dell forums. I hope this little push make them finally fix the issue. If not, i would be really disappointed by dell support...

 

I´am also very satisfied with LGD02DA display, it suits to my needs better than reflective true life, because iam not big fan of 3D.
I haven´t seen the third panel though, so i can´t say the difference.

 

I do have the same CMN1720 panel, and it's pretty decent, considering the price of the laptop... before you write the display off, grab the icc profile from the notebookcheck.net review. It makes a huge difference in quality, at least it did for me.

I completely agree with their conclusion about this screen:

 

What's a shame is that others that have THE SAME LAPTOP have a much better display (LG), that looks fantastic, and is capable of professional color work. While in the end, conclusions like the one above might make you sleep better at night, it doesn't help much if you're not happy with how it looks every time you turn it on!
When you buy a product like a notebook, every one off the assembly line should work and look the same. If Dell is going to use different brand panels, they should all look of equivalent quality.

I wouldn't want to have to convince myself, every time I turn it on, of all reasons why it's OK it looks bad...

 

How do you change display profile in Windows 8?

 

How exactly have you come to the conclusion that the LG panel is far superior? Have you compared them side to side after color calibrating both of them? Is there a serious comparison of the two panels posted somewhere online?

 

I didn't say it's "far superior", I said it's "much better". Since I have the LG panel in mine, I know it looks fantastic. Since I've owned around 100 laptops (mostly Dell but with some HP) with varying quality LCD panels (from practically every panel manufacturer), and the fact I have two eyeballs, I know that it looks vastly better than most panels in mainstream Dell notebooks. I know I didn't have to color calibrate my screen to make it look good. I know that in past Dell laptop models, the Chi Mei model was usually the one with lesser quality. I also know that LG panels are highly rated and generally preferred when given a choice.

If you're interested in a "serious comparison" of the two panels (for what purpose since we both already own them?), feel free to look online. I'm completely happy with my LG panel.

Looking through that review you referenced, I didn't see where they stated which panel was in their review unit. Their data and conclusion could have been based on the LG panel. Who knows? Do you know that ICC profile you installed was for the Chi Mei panel and not the LG panel?

The couple of complaints I've read about the panel in the 7720 have stated they have the Chi Mei panel.


Update: I happen to have had two other in-box 7720 notebooks in stock (for my business). One has a LG and the other has the CMN1720! In a highly unscientific test, I put both units (mine w/LG and other w/CMN1720) side by side and set both desktop wallpapers to use a JPG that is used as a high-end printer test page and comprises 16 individual photos of varying types (vibrant, colorful, night time, portraits, HQ B/W, etc.). In my opinion, there is a difference, but the difference isn't as bad as others have stated. The LG is slightly brighter, and more vibrant. In the B/W photo sample panes, the LG is able to display more detail in the darker areas. A couple of the photos look more natural on the Chi Mei. Overall, I'd say in this case, the Chi Mei and LG are both decent panels, but if I had the choice, I'd choose the LG.

I'll try the ICC profile on the notebookcheck.net site for this model and see if it makes a difference (on both units).

 

sorry, my bad!

I've worked in IT for the past 15 years, I've also seen my fair share of LCD panels, and I would also, like yourself, consider my screen vastly better than you find on most mainstream notebooks...luckily, I also have two eyeballs.

That's the thing, I've never seen a serious comparison, just rumors. I've also seen my share of bad LCD panels, and I, like you, am perfectly happy with the sceen I have, which happens to be Chi Mei. ...

Based on the icc profile posted, it's definitely the Chi Mei panel they reviewed. Confirmed by myself and a few other 7720 owners on this very thread a few pages back.

That's exactly what I'm driving at here. I've so far only read about 2-3 rants regarding the screen quality, which happened to be Chi Mei panels. This alone does not convince me these same people wouldn't post the same rant had they received the LG panel. Different people, different expectations...

I was just wondering whether you're basing your conclusions on facts, or just the established rumor that the LG panel is "much better"... rumor it is, I guess.

P.S. I don't want to come across as defensive just because I have the Chi Mei screen in my 7720. I am genuinely interested in a comparison of both panels, or at least a review from someone who has seen both side by side.

 

realG, see the update to my previous post. I agree with you on the Chi Mei. Those that are complaining must have another problem with their Chi Mei.

I just installed the ICC profile from notebookcheck.net on both 7720's I have and set the profile to be the default profile for the monitor. To be honest, I don't see that anything has changed. Neither panel seems to have changed at all. Am I doing something wrong?

 

I applied the profile. It's inaccurate. Finally I manually made the settings by searching online. There is an improvement but the quality of the panel still sucks. One of the tests had patterns for testing jitter and my monitor got jitter in 2 of the patterns (even 1 is unacceptable for a "good" monitor). And you can't calibrate your way out of jitter.

 

I got good news.. after many escalations, I was contacted by Dell support they look at the gpu boost problem and they will contact us in next few days.
Please, make the final push and urge this case in my post again - Re: Dell Inspiron 7720 SE - Gpu boost is turning off - Laptop General Hardware Forum - Laptop - Dell Community

if this bug will be fixed, iam gonna start believe in miracles )

 

Cool, thanks for the interesting update... you should definitely notice when you apply the icc. Make sure that when you set up the profile, go into Advanced tab, click "Change system defaults", Advanced tab and tick the "Use Windows display calibration" checkbox. Without this, the profiles won't get applied. You also need to disable the Intel Persistence Module (igfxpers.exe) from loading, otherwise you lose the calibration every time the laptop switches between the GPUs. Check this thread for an easy step-by-step: http://forum.notebookreview.com/alienware-m11x/492790-m11xr2-calibrated-lcd-icc-profile.html

 

Do you have a link for the tests you performed? Are they free?

 

Yes, it's free, you get it here LCD monitor test images

I get flicker in 2a and 4a..

 

there is no flickering on LG panel, iam pretty suprised, because my deskop PVA panel at work slightly flickers.

 

well. if you ever have play new games (for ex BF3, MW3, CS) on a 120Hz screen (non 3d) you know what im talking about. (less screen tearing, smoother mouse, more crispy image quality, etc)

i will never going back to 60hz screens after using a proper 120Hz. (it doesn't matter if i reach 120Fps in Bf3...the flow is still better when i use 120Hz settings)

take for example MW3......oh my God...it soooo much better game play when i have 120Hz refresh and hit super high FPS

and if speak about games who is less gpu-demanding then BF3.....well what can i say.......you miss the fun part having true 120FPS on a 120Hz screen... its mind blowing.

 

I'm sure you mentioned somewhere in the last 1700+ posts, but how did you get a 120Hz panel in your 7720?

 

i think 120HZ is minimum requirement for having 3D image - (60HZ for each eye)
I have seen lot of games in 3D or in 120HZ and haven´t recognized any difference. but, who knows, maybe my eyes are cursed by 60HZ era and its only me, who cant say any difference;-)

 

Ah...so the 3D version of the 7720 has the 120Hz screen then...I misunderstood KSMB's post. I thought he didn't have 3D, but I think he meant he doesn't use 3D.

 

Hi. I've had my 7720 for about a week. The only issue i'm having right now is the wifi keeps dropping, anyone manage to solve this? I'm using the latest dell drivers.

 

Use the intel utility:

Intel® Driver Update Utility

 

Thanks. Updated my wifi and hd 4000 drivers, lets hope it works good now.

 

i use cable straight from the fibre-connection into my PC......always have, always will.......its ten times better !

(only time i use wifi is on my iphone...little hard to carry around the fibre cable...he heeee

 

Technically not 10x faster, since the network card is only 100Mb.

But on a serious note, I'm sure you appreciate not everyone has your infinite wisdom to only use wired connections with their portable laptop, so a discussion on how to make the wifi stable and fast is pretty valid.... but then again, judging by your past contributions to this thread, one never knows.

 

KSMB I will agree with RealG on this one, albeit I will not disguise my message with sarcasm. Not trying to insult realg. But he is correct in saying that the user had trouble with his wifi and you only made a statement saying that you use a direct connection which does not help him whatsoever nor anyone else in this thread. Just saying !! Otherwise I really don't think you are troublesome or annoying.

 

Thanks for the suggestions guys, but a wired connection isn't something I can do, and I bought the laptop for mobility.

 

Notebook, check

Ordered 16GB RAM and 256GB mSATA SSD, check

Do you think that i am going to need a cooler??? In addition what kind of calibrations must I do to it?

Thank you in advance

 

Maybe the issues are not with the laptop's wireless card but with the wireless router/ap you are using? Have you check the manufacturer for an updated firmware? Also the rest of the settings like channel number, channel width, etc

 

My router runs fine with every other wifi device in the house.

 

I installed the mSATA SSD 256GB not for caching, but I intend to use it for the OS and programms.

Unfortunately, the windows explorer does not recognise the SSD. What have I to do?

How can I keep the windows licence and install it to the SSD?

Thank you in advance.

So hows the progress on getting that boost bug fixed? I will actually be purchasing this laptop next month and want the best gaming experience. Im excited!

 

With this way, the system determines which data will be stored in every partition. I want to determine by myself where to install what. Is that possible??

What are the BIOS configurations in order to have my SSD recognised by the windows???

Is it better to migrate the OS from the HDD to the SSD?? How can I do that?

I am sorry, I know that those are to many questions, but I find the whole process a little difficult.

 

Can you explain what issue you mean?

 

I think you'd be better of asking these questions on dedicated Windows 7 forums, as they apply to all PCs in general, while this is a forum discussing a specific laptop model.

In short, If you do not see the new SSD in device manager, make sure it's properly installed, also check in BIOS that the SATA controller is set to AHCI. That's pretty much all you can do in terms of hardware setup.

Your new SSD should now be listed in device manager. However, that does not mean you will see it as a new drive in Windows. You need to make sure it is formatted and that it has a drive letter assigned. Google disk managment in Windows 7 to learn more.

Easiest way to "migrate" the OS to a new disk is to do a proper clean reinstall. To do this, you need the Windows install disk. If you have not received it with your laptop, you will need to ask DELL to send you one. Then it's just a straight forward Windows install, during which you select the SSD as the system disk.

I guess first things first, check the ssd is installed properly and listed in device manager. Any questions ask away and we'll try to help.

 

Thank you for the reply!

The SSD is properly installed as the BIOS "sees" it. It was idiotic not to formate it :$

Hope that Dell will send the OS disk...

 

They did for me. Tell them another adviser said to ask for one, that worked for me.

 

Hello,

Last Tuesday I received my new mSATA M4 256 gb of Crucial and I tried to install it, but unfortunately I haven't had any succes so far. That why I'm reaching out to you guys.

I have a 7720 with 2x 1TB HDD and I want to put those 2 in RAID. Then I want to install Windows 8 on my mSATA via an USB recovery-stick made by the Dell back-up and Recovery program.

I have tried several things and nothing works. According to a thread I should be able to install Windows on my mSATA when I remove my 2 HDD. But this wouldn't work either. In this case the Dell Recovery program starts and then short before starting the recovery process, I get the following message;

“Your hard disk isn't suitable for this process. Use a HDD with at least 931 GB of free space”.

Very strange, isn't? Due to the fact, that there are a lot of folks here with an OS on their mSATA.

Could somebody please help me with this?

 

I mean how some people have an issue with the gpu randomly throttling during gaming even if the temps arent at 90 degrees cel. Iknow there was some type of work around though but I dont quite remember it.

 

dont you have turn on v-sync? try to set the maximum performance in nvidia control panel in manage settings tab.

 

Hi guys,
any idea how to fix the keyboard flex? getting quite noticeable flexes around the middle of the keypad - especially close the numberpad

 

Some double sided foam tape on the bottom of the keyboard is probably the only trick.

 

Nope. I dont own this laptop yet. Im just learning the things id need to learn before I get it.

 

maximum performance is no joy for the eyes.............image quality is pretty mediocre that way..............
i would recommend stock settings (50/50....... performance/quality)
--------------------------------------------------------------------------------------------------------------------------------------
ps...a tip...for example in BF3/crysis 2 (do not have v-sync on.....gt650M does not handle high stable FPS in 1080p

(sure, if you go down to 720p resolution...you can turn that sucker on)

you need at least a GTX670M to have some kind of pleasure with v-sync on in 1080p

 

i meant maximum performance in power management tab, sorry

 

Hi, i have 2 question,
first is about my new ssd m5 pro 128GB, its now my only one HD inside dell 7720, and at almost pure Win 8 i have only 20/40 mb for 4K. Isn't it to small?


and second Q, before i get win 8 I was using win 7, at 7 my battery hold about 3-4h, and now only 2(charging @ saving battery) :/ HD4000 is set as default.

Is it all normal or smth wrong?

 

Looks to me that the DELL Recovery program can only restore the image to a disk with a minimum size of the original disk it made the image of.
So try a clean install and see if that works.
If that works, try another imageing program... (no experience with any such program so can't help you there i'm afraid.)

 

Ring Dell and tell them the recovery discs don't work. I did that after someone on here said, and they sent out a new windows 8 disk for next day delivery. I think they must have pure problems with recovery discs /partitions that they didn't really query my problem.

 

hi guys I just would like to ask for your opinions, I recently acquired my laptop. but it seems my screen is having weird viewing angles specially on black. I asked a dell chat assistance but no luck yet on finding a solution. Unfortunately laptop is outside the US now Havent ask for the a service transfer yet.

here's some picture and video
