Dell Precision M6700 Owners Thread

Looking for some help hopefully some can help I have the M6700 Covet i7-3940, 16GB 1866, Quadro M4000, Win 7 64bit, Dual SSD's RAID/0, I have 3 24 monitors connected to the docking station (1080P) and a 22inch connected with USB adapter and the laptop screen. Since I work with a lot of CAD,Visio, drawings. I have been struggling with the limited resolution so a new center monitor was in order. I picked up a Dell 4K P2715Q monitor and I'm trying to figure out the best way to hook up the new monitor. I plan to drop the USB monitor currently I only use it for documents in portrait view. The new monitor supports Display port 1.2 and it says I can daisy chain the monitors can this be done with 4k monitor and 1080p monitor? The docking station has two display port or dvi outputs and a VGA output.

 

The DVI outputs on the dock are single-link — The only way to hook a 4K display up to this machine is with DisplayPort.

There is a bandwidth limit on how many monitors you can daisy chain. I don't remember the details but we had someone try chaining both 2 and 3 monitors either earlier in this thread I believe. The more monitors you connect, the less the max resolution of each of them can be. I highly suspect that you won't be able to run that 4K monitor at 4K if a second monitor is connected in the chain. However, you should be able to chain two 1080p monitors (if the monitors support it of course).

You can use the DisplayPort on the right side of the laptop itself in addition to the ones on the dock to hook up an additional display without chaining.

 

Thank you for the info the three 24 inch monitors are the Dell U2412M they support a max resolution of 1600x1200 not the 1080p I stated before sorry if that created any confusion. my current monitors a have the display port, dvi, vga. Overall I just want to run three monitors and not rely on the laptop screen. Left monitor will be a 24 in portaitmode 4k in the center in landscape mode and for the right 24 monitor will be landscape as well.

My docking station if the Dell Port Replicator with USB 3.0 it has 2 DP 1.2 I was hoping to cut down on the cable clutter. I suppose I can run DP,DP, VGA.

 

need help guys. My 6700 is dying recently. This weird symptom:
- Whenever it goes sleep or shut down properly, the next boot will failed.
- By fail it mean when i press the power button, the screen stay blank, no power flows through. The volume button and lights on but the indicator only had static power source LED.
- I need to repeatly press power button to force it shut down, and press power button to boot it up again until it manage to boot up.
- Tried FN + power button, same issue only with the indicator is having blinking power source LED.

I had something like that with my M6700 once - it wouldn't power on fully (the screen was blank and there were no signs of it booting) one day. What I did was remove the bottom lid and disconnect the CMOS battery for ten minutes and then it worked. Haven't had the problem since (I have the laptop for almost 1.5 years).

 

Those kind of issues are really hard to fully diagnose. Is your M6700 still under warranty, it might be a good idea to contact Dell if it is. Another thing I would check is the manual to see if there is something in the troubleshooting section about those kind issues.

 

I used to think I had a solid understanding of max video capability of M6xxx series: When used with ePort2 dock, you can drive 2 honest 4K monitors @ 3480 x 2160, then you get one more monitor thru the VGA port but its limited to 1920 x 1080 max res due to analog interface. I've been waiting for Dell to introduce a precision model that could drive more than 2 external 4K monitors, but assumed it was still a ways off.

But when I stumbled across the Dell 3100 video "dock" (see http://accessories.dell.com/sna/productdetail.aspx?c=us&l=en&s=bsd&cs=04&sku=452-BBPG), which appears to provide ay computer with USB3 with a way to drive one more 4K plus two more FHD panels. So at first glance it appears that with this handy gadget and an ePort2 laptop dock, you can run (3) 4K monitors and 3 more Full HD monitors (2 from the 3100 and one from the ePort2).

My real goal is to drive (4) 3840 x 2160 panels with my m6700. It would appear this is now possible by buying 2 M3100s, or perhaps some other device (suggestions on those VERY welcome) from another mfr. that can drive 2 4K DisplayPort panels from a single device so I only need one of them.

What do you guys think? Has anyone actually tried this? An m5000 with 4GB memory is plenty of video card to drive (4) 4K panels. I'm not a gamer and don't care about super fast frame rates. Just a lot of stock market charts that never update more than once a second...

Thanks,

I should have mentioned in my last post... The obvious way to get 4 DisplayPort monitors on an M6700 would seem at first to be DisplayPort disy-chaining (MSP). I experimented with that and found that while it is possible to daisy-chain several Full HD res panels, I was not able to get 4K (or even 2K) res from daisy-chained monitors on my m6700 with K3000 video card. I welcome enlightenment if I was doing something wrong, but my conclusion at the time was that DisplayPort daisy-chaining doesn't work at full 4K resolutions.

You might be hitting the limits of the displayport revisions with the daisy chaining. That USB 3.0 dock will not use your video card for the displays and like any video through USB, depending on what you do, the latency incurred by the use of USB 3.0 video might be an issue.

 

With the pr02x, you get 2 displayport on the dock and 1 on the machine, so 3 port there. So that's 3 if the gpu can hold up.

 

The DisplayPort spec indicates that you won't be able to daisy-chain multiple monitors at 4K with DisplayPort 1.2, at least at 60 Hz.



As others have mentioned, you should be able to get three displays using two DisplayPorts on the dock and the additional one on the laptop itself. I'm not aware of a way to get another one without using video over USB which brings its own set of issues.

Actually... The HDMI should be able to drive a 4K display at 30 Hz. I've never tried to use HDMI while the machine is docked but it might be possible with some sort of "elbow" connector cable.
