M6600 Owners Thread

I prefer the glossy display myself. This one can go either way.

No one else has seen this issue with the AUO panel.

 

Dear dvanburen,

There are people, who have better hearing and some electronic squeal is not too nice for them. There are people with better voice and they normally sing some songs. We also differ with eyes - some of us are less vulnerable for some issues, some more. This is like with temperature - some people will say for air temperature X Celsius/Fahrenheit "it's cold", some not.

Fact, that glossy screen with reflections is better for you, shows that you're probably less vulnerable for some things and it doesn't prove anything. Fact, that I can proove some picture inconsistency with digital camera (it was done already on this forum) shows that there is very low PWM frequency used.

I say, that it would be excellent to increase PWM and have more matt to improve user experience and it's not against reports from other users (and additionally - this voice should be treat equally).

Additionally - there are some device classes, where marketing shouldn't be more important than real needs (for example: gloss screens are mainly put everywhere, because they're "more nice" in shops; when you will look into any site with reviews or any forum, you will see, how people HATE it; currently I think, that first company, which will resign from it in each segment will increase sales a lot).

That's all.

 

Is the M6600 glossy M6500 Covet "glossy" or Crapbook Pro full-on glossy? The former's not that bad. The latter is bad.

Man - brings back bad memories of the M6500. And the M6400. And the XPS M1330. And the XPS M1730. And... well, let's leave it there.

I wonder how typical this is, because it seems in my experience that if they get it wrong the first time, you just end up going around and around in circles - presumably because you're allocated returns and refurbs (if they're available) with specs *similar* to what you originally ordered until you totally lose your rag - but if they get it right the first time, the chances of you having issues are pretty few and far between.

PS: Never had this with Elitebooks so far.. just sayin'

 

Maybe I overreacted a bit, but I think you completely missed the point. These are your opinions and not facts. These opinions can vary greatly from one person to another.

I'm not less susceptible, I only use my laptop indoors and I position it to avoid glare. I prefer the glossy screen and it suits my use of the M6600. If you really want a matte LCD panel then source one and swap it. It takes maybe 15 minutes if you know what you are doing, 30 if you take your time.

As for the PWM issue, I can't reproduce your results. Please note, this wasn't a test based on eyesight. I tested with a Canon HF100 camcorder using the exact same method in the video you linked. Additionally, I have not seen one other person complain about this same issue. All the flickering issues refer to a different issue with the LG panels. This implies that either there is an issue with your specific laptop or you have a general issue with eye fatigue. If this was a general issue with this laptop your would see a plethora of complaints flooding this very forum.

Sure, these would be good options to introduce when a refresh rolls around, but it shouldn't and doesn't take away from the M6600 as a whole.

Dell onsite techs scare me. If I were you I would insist on parts only replacements and do the work myself.

vPro is nice but may only be useful if you are going to need remote access at the hardware level (mainly troubleshooting and/or remote power on) or if it will be in the hands of an untrusted individual. In all honestly I wouldn't have pursued a replacement when the 'forgot' it on my second laptop if they had given me any sort of upgrade, preferably CPU. Well, that and the CSR had the worst attitude and customer service I have encountered in years.

 

They assigned me a higher level CSR, and after getting a new production replacement with a flickering LG panel, he said the only way he could guarantee a AUO panel was to order the touch screen. I guess the current batch of touch screens are all AUO. I wanted to go for a new production M6600 after our experience with the awful on site tech, and after reading in here how some owners were getting their flickering LG panels replaced with flickering LG panels.

At least now we have an AUO touch screen panel with 2760QM , but I wonder how useful the touch screen will be to us. It also loads windows a lot slower than our 2720QM, but that's probably related to the Dell software they have on the 2760QM, like the update software. It could probably benefit from a clean install of windows

 

I agree...nothing is perfect, including the M6600, but we need to look at documented facts and not conjecture -

Fact: The AUO V5 is matte and has the same industry standard AG coating specs as many other panels. It should be noted that excessive AG coating to remove all [indoor] reflections would only degrade the overall image quality; making potential reflections moot. Reference the CMO panel as an example.

Fact: For photo and video production, a glossy display indoors with reduced room lighting will always produce the best image results.

Fact: There are no PWM issues that need to be addressed on the M6600 system board side in relation to the AUO and/or other panels.

Scott-

 

You guys talking about PWM or PMW?

this is from the LG LP173WF1 spec sheet..

8. The operation of LED Driver below minimum dimming ratio may cause flickering or reliability issue.
9. If Jitter of PWM is bigger than maximum. It may cause flickering.
10. This Spec. is not effective at 100% dimming ratio as an exception because it has DC level equivalent
to 0Hz. In spite of acceptable range as defined, the PWM Frequency should be fixed and stable for
more consistent brightness control at any specific level desired.
11. The life time is determined as the time at which the typical brightness of LCD is 50% compare to that of
initial value at the typical LED current. These LED backlight has 6 strings on it and the typical current
of LED’s string is base on 22mA.

 

Pulse Width Modulation, which in the end is controlled by the panel's onboard controller logic; not the main system board.

Question for you guys. Which brand/model of glossy screen would you recommend installing that has excellent quality and would be compatible with the M6600 without flickering or any other issues?

I do a lot of photo and graphic work (mostly indoors), so it MAY be worth me switching to a glossy screen just to get the better contrast and color reproduction.

Thanks!

 

That's really odd. Both of my replacements were factory new and they both had LG panels. Yes, I have a touchscreen. In both cases I swapped the AUO for the panel in the replacement. Either way, glad you finally got an AUO.

AU Optronics B173HW01 v4 is probably the best you can get w/o going IPS. Make sure it's a v4 as each version is significantly different. This particular panel displays 90% of the NTSC color gamut. I can't comment on compatibility first hand but I am 100% confident it will work w/o issues.

Edit: Here are the specs.

I suspected as much but it is nice to have it confirmed.
