M4800 Owner's Thread

Personally, I would leave it in, if only to serve as a backup power supply for your machine.

 

Can someone please share a link to a 200w docking station. Thanks

I'm sorry, I meant 240, not 200. I got mine on eBay.

 

I run my M4800 regularly on 90W power supplys that I also use with my D830.
It will then complain on startup that it has to run with reduced performance, but for normal light computing it seems enough.

Interestingly this warning screen is also the only way I can get GRUB to display it's screen when the machines starts. My M4800 runs on Linux (Xubuntu 14.04 to be more exact).

 

Hi everbody !
I'm posting here because I can't find some informations about the M4800 on the internet.
I think I will order a configuration with a Firepro M5100 and a "FHD ultrasharp screen". But nobody's talking about the performance of this graphics card and the accuracy of that display.
So here my two questions :
-Does somebody know about the performance of the Firepro M5100 in CAD applications (Top Solid/Catia/Solidworks), in photoediting softwares (Photoshop CS6) and in games (need to relax sometimes ).
-Same for the FHD ultrasharp screen : What about the gamut, the contrast, the color accuracy, the black level... (even just a personnal felling would be great help )

Thanks !

 

Hello,

I've got the machine you are asking about. Display shows strong granularity and initially I had problem with white showing as yellow. While the problem with yellow turned to be issues with drivers, granularity of the screen caused me eye strain.
I've contacted Dell to see whether they can replace the screen, but they simply told me to return the computer and order one with better screen (i.e. QHD with Quadro etc) instead. I'm not happy and I have sent the unit for return yesterday.
The problem with screen granularity has been reported in M4700 & XPS threads as well. It's also called screen door, you can look through notebookreview forums for examples of posts for this problem. What I read is that people are changing LCD panels themselves, but Dell sales rep told me that this will void warranty.

 

I would 100% agree with mikalaj on the screen door effect.

I'm currently evaluating both the M4800 and the Latitude E6540 with the FHD and they both have it although, believe it or not, the screen on the cheaper E6540 appears subjectively better. I'm definitely returning the M4800 and possibly the E6540 as well although initially I was planning on keeping the Latitude. Just knowing the issue exists bothers me in a machine of this caliber/cost. The display on my four year old Dell Studio machine is better.

 

To be fair the screen on my old studio machine was fantastic. The QHD+ one is also great, but the viewing angles aren't as wide.

hi,

i noticed on my m4800 (quadro k1100m) that my whites are a tad yellowish and there's a slight blue tint overall. my question is, what is the best way to calibrate the colours? in the intel hd graphics settings, the nvidia settings, windows display settings or changing the colour profile?
any help is highly appreciated, thanks a lot! J

 

Anyone with the QHD+ display care to comment on if the screen door effect exists on that display?

Specifically, would you mind lowering the resolution to FHD (1920x1080) and letting me know how it looks.

I'm definitely returning the M4800 with the FHD display because I think it's awful (otherwise like the machine) and I'm debating either keeping with E6540 with its acceptable, though not great display, or biting the bullet for around a $400 premium and getting the QHD+ and running it at non-native FHD resolution. I did that with the T540p's 3k display and it worked [surprisingly] remarkably well. Too bad the keyboard and touchpad on that machine were absolutely atrocious.

Thank you in advance!
