M6600 Owners Thread

I was checking with Samsung Galaxy S. With good backlight you shouldn't observe even minor effects with any digital camera (why ? for part of people they seems to be enough to have tired eyes).

After reading your note conclusion for me is still the same - M6600 is very good, but currently not so excellent like should be. I hope, that Dell will not leave users alone and can fix at least backlight with BIOS (picture quality should be ideal and there are no excuses here)

 

Not that simple. With Optimus enabled, all graphics output to the screen is driven by the Intel card. The NVIDIA card just flushes stuff over to the Intel card's frame buffer to be displayed on the screen. So because the Intel card can't do 10-bit color, you can't use Optimus --- the NVIDIA card actually has to directly drive the display all the time.

 

There is one interesting topic here - can't Dell add some BIOS option for selecting which card (integrated/additional) will be enabled and used until next reboot ? From technical point of view it should be probably very easy for implementing... You could use integrated graphic and sometimes switch to additional then.

 

Where can I get a catalyst driver for those switchable graphics cards? I guess these driver should be able to switch between integrated/discrete graphics cards.

 

The switchable graphics is only with the Nvidia cards in the M6600

 

yes, this is what I'm talking about - such option doesn't exist now, although could (adding it in BIOS would be probably very easy for Dell and it will work like plugging off external card from the socket).

 

Sure, actually you can do it already.

Optimus enabled = use Intel card (the NVIDIA card can render stuff via framebuffer trick)
Optimus disabled = use NVIDIA card only

Not that simple if you have an IPS display, though. I haven't seen a machine with the IPS display but my understanding is that they will force you to run with Optimus disabled if you have the IPS display. But if the Intel card is actually capable of driving the IPS display (albeit with only 8-bit color channels), then it should be possible..... I don't know if something with, say, the physical connector to the screen would prevent the Intel card from working with it.

Optimus is the result of a collaboration between Intel and NVIDIA (mostly NVIDIA I believe but some software/driver support required from Intel) --- so it isn't possible to use with ATi cards at the moment. For more information as to how it works, here is a pretty good write-up: http://www.notebookcheck.net/Nvidia-Optimus-Review.25467.0.html

 

99% of the time I run on 100% brightness. At this level there is no flickering at all. I think this issue would only effect a very small subset of users. You would have to run on minimum brightness AND be very sensitive to flickering. How many people really run on minimum brightness for extended periods of time? Maybe I'm wrong here but I think this is an extremely small percentage of users.

That said I personally believe the flickering you see is exacerbated by the difference in the LED frequency used to achieve minimum brightness and the refresh rate of the camera sensor.

Edit: Just to reiterate, the flickering is MUCH less noticeable with my AUO panel and my HF100. It looks nothing like your video. You may want to look into getting your panel replaced, but it could just be the camera you are using.

 

Received my DELL M6600 last wednesday. Excelent machine. Upgraded to 32MB ram (4 x CORSAIR CMSO8GX3M1A1333C9) and removed the 250GB SAMSUNG HD and replaced it with two SEAGATE hybrid 750GB drives.
Reinstalled Windows 7 prof. with the nessecary drivers. This machine will from now on run VMWARE workstation 8.
LG screen, Intel i7-2760QM, AMD Firepro M8900

Have already a Dell Studio 1737 with 8GB ram (and blu-ray), buth a little bit to slow to run Workstation.

 

OK, I will maybe explain some things from beginning: I need stable, fast, silent system with good anti-glare display. M6600 has got some very strong points (like two fans, MXM card or nice help with CM LCDs), but also some weaker (and I can of course ignore some issues - for example I can exchange default HDD on my own).

Currently I'm trying to setup picture on it exactly like my old laptop (the same Clear Type settings, using Tahoma instead of Segoe UI, etc.), but something is still wrong

I see a little worse anti-glare shield on AUO than in my old laptop (maybe this is partially reason ????) and it looks, that brightness control is done wrong (to explain - I don't care about visible strips in my digital camera, but I take care about my eyes feelings and camera confirms it without any doubts).

Working with full brightness is not solution for me, Dell could probably at least fix blinking with BIOS (I have feeling, that it's not panel/MB issue, only frequency setting). When it will be done with success (I will have similar eyes feelings like in my old system), I will be able to say - this is really premium system.

Please note, that I'm not first person complaining about blinking here (and video on YouTube wasn't created by me). Without help (Dell can of course say like you, that described things can be ignored) we will probably have to select Lenovo or other company.

That's all, now waiting for Dell's move
