Next Generation Dell Precision Mobile Workstations press release

I connected the asus this time using HDMI. I don't have a thunderbolt cable adapter else I would try it.

The screenshot below is with the external connected to the HDMI port



Next is a screenshot of the Physx setup. This is with the Asus plugged in by the HDMI port. This screenshot is very similar to the Physx screenshot I posted early but this time using HDMI. Note that the port now appears as HDMI instead of as a DisplayPort



Here is another screenshot from directx diagnosis tool. Again, this time the display is connected by HDMI and is using iGPU

 

Thanks for the information. It sounds likely that all of the output ports on the machine are connected to the iGPU, while the ports on the dock are connected to the dGPU.

The funny thing is the more I read about the 7710 the more I realized that I just wanted a Haswell version of it. So I read a bit about the M6800, noticed that Dell started making them with eDP displays a few months before they were discontinued. I found a nicely priced model on the outlet and went on ahead and purchased it. Now I will have a M6800 as a primary machine, and a Latitude E6540 as a backup (or lighter / smaller option if I am on a flight). Both have excellent Linux compatibility and should easily be more stable and have less headaches than Skylake for another six months to a year. I will even have a Quadro card with the M6800 that I can use to play a game if I want to, and may be able to install a 980M in it down the line from what I have read in the owners thread. The price is also about 50% what I would have spent on a Skylake machine. The only downside is no USB-C, but for now that is not a big issue. It likely would not work very well for a while under Linux anyways.

 

If you get one with an AUO B173HTN01.1 screen and need a color calibration profile let me know; I made one with dispcal and an X-Rite i1DisplayPro. The screen is really 'cool' by default but after correction looks much better than your average TN. There are also profiles available from notebookcheck.net.

The only linux issues I've found with the machine are
1) Tearing on DP/HDMI with optimus/enduro enabled (I have a firepro)
2) Popping from speakers at bootup with current kernels, may be fixed in later versions (add snd-hda-codec-realtek to a kernel blacklist file to fix)

 

I have the TB15 for the 7710. Trying to hook three monitors with DVI adapters. I can only get two to work. It looks like the Intel Graphics is taking control and not the Nvida (I have the Nvidia M5000). In the Nvidia Control Panel, PhysX, it shows the Intel Card controlling.

Any ideas?

Edit 1:

I changed a mDP to DVI cable from a Passive to Active (Need active for my Surface Pro 4 dock). The DP to DVI is passive still. It did not work.

I rebooted a few times and disconnected the TB cable from 7710. At first there was no power at the TB cable (light not on). Then all of a sudden, the three external screens came on.

I will try and see if the passive mDP to DVI cable works too.

Edit 2:

I switched the mDP to DVI back to the passive cable and it works.

The Nvidia PhysX shows the screens are on the Intel Graphics Card.

Edit 3: Here are some useful links.

The trouble shooting on the second list is similiar to installing the drivers on the dell forum link. Note, I did not install all the drivers in the noted order (found links after).

Also, for the "USB audio/mouse on Dell Thunderbolt Dock and Dell Dock" this is not listed under the downloads for my service tag. However, I installed it anyway after I was all connected.

TB15 Power On Observation:

While powered off, I can hook the 7710 up to the TB15 along with the separate 7710 power, hold the TB power button for a brief second, and it will turn the 7710. I noticed I can not do a quick press of the power button, but have to hold it for a fraction of a second.

Also, once booted to windows, The network and wireless keyboard are not picked up right away. Without the dock, I can move the track pad or press the number lock button to key in my pin right away. With the TB15, have to wait a few seconds (I did not time it) for the dock to be active for the wireless USB keyboard and network connection. However, two of the three monitors show on power on (Dell Logo).

 

Its almost like even when Nvidia GPU is being utilized it still passes through the Intel. Could be that I just don't understand how to interpret that physx. As long as the quadro is utilized when i need it to be, I'm good.

I have noticed though, and this is true on my m6500 and even my MacbookPro too, sometimes I have to unplug and reinsert my display port (only on first time) after first connecting the display to the laptop. In my case it may be more related to the display than with the laptops.

 

WOW! Thank you for this! I've been working for 10+ hours trying to get my GPU to work. Just put fastboot to minimal and it now is working!

 

Hi all, I may come in late into this thread, but I'll like to share some differences between the XPS 9550 and the Precision 5510.
Differences for the screen options only, nothing else. If any of you guys knows more about the screen differences, PLEASE post it, as I'm ready to upgrade my dying Panasonic Toughbook F9, and I can't decide between the XPS or Precision.
I hope the screen specs I'm sharing helps some of you as well.
So far, this is what I found:

XPS screen 15.6" 4K Ultra HD (3840 x 2160) InfinityEdge touch
Precision screen 15.6" UltraSharp UHD IGZO(3840x2160) Touch Wide View LED-backlit

the FULL details about this screen/panel can be found on the review XPS page from notebookcheck.net
15.6 inch 16:9, 3840x2160 pixel, 10 fingers, SHARP LQ156D1JX01 Dell PN: 7PHPT, IGZO WLED 330 cd/m² 1000:1 Hard Coating 3H, glossy: yes
On panelook.com you can see the FULL specs of that panel LQ156D1JX01
My understanding is, that both XPS9550 and Precision5510 are using the same 4K panel, as DELL is using Sharp screens, and Sharp only makes one glossy version of the 4K panel on that size.
FYI: there is the LQ156D1JW04 antiglare, this one may be used on the Precision 7000 or other brands/models.

NOW, as good as this 4k screen is (except the crazy screen glare), reading text on 15.6" screen with a resolution of 3840x2160 can only be done thru scaling 250% or maybe 225% (and none of those scaling are integers) resulting in text being blurry.

THE IDEAL RESOLUTION for 15.6" laptops screen would be 2880x1620 at 200% integer scaling (see the Lenovo W550s 3k).
I got the chance to play with this Lenovo W550s 3K IPS matte screen laptop, and it is amazing.

As for the Dell XPS or Precision, I'll suggest getting the FHD 1920x1080 matte screen.
Unfortunately, even this lower resolution will still need to be scaled at 125% maybe 150% (non integer = blurry)
DELL is listing the XPS as being: 15.6" FHD (1920 x 1080) InfinityEdge
and the Precision as being: 15.6" UltraSharp™ FHD IPS (1920x1080) Wide View Anti-Glare LED-backlit
NOW...
the FULL details about this screen/panel can be found on the review XPS page from notebookcheck.net
15.6 inch 16:9, 1920x1080 pixel, Sharp SHP1453 LQ156M1 Dell PN: 1203M, IPS, glossy: no
On panelook.com you can see the FULL specs of that panel LQ156M1LG21 as a standard TN panel, antiglare, viewing angles 80/80/80/65, contrast 800:1 (ALL THIS IS FOR THE XPS and I don't think is IPS screen)
Maybe the Precision screen is the LQ156M3LW01 as an IPS panel, antiglare, viewing angles 85/85/85/85, contrast 1500:1 (as Delllist the Precision screen as an "UltraSharp" FHD IPS) (but i'm not sure)

Dell sales reps or tech support won't share, or don't have a clue, about the screen differences between the XPS and Precision, other then telling me exactly what I see on their website, bla bla bla... things like the Precision has a better screen, without actually providing any proof of screen specs differences.

Do any of you guys own a Precision 5510 with the 1920x1080 FHD ?
Can you check and post the full specs of the screen/panel and brand/model.
Can somebody confirm that those screens on XPS and Precision are different or exactly the same?

This will help me, and maybe others, with valuable info, and easy decision making, in terms of deciding if the XPS is ok to purchase, or the "maybe" better screen of the Precision is worth paying for.

I'm new on this forum, and I do apologize for the loooong post.
I'm just trying to shed some light on this screen differences (or not).
Maybe Dell-Mano_G can pitch in.
Thanks guys.
Hope you enjoyed the reading.

 

That did it!??! awesome! I wasn't sure if that was what fixed mine. I'm glad that did it for you too. I changed mine back and forth a few times since then and the dGPU is still working and visible, so I wasn't sure if that is what made the difference/fixed it. very cool

 

Maybe it's caused by an invalid default bios setting, and changing that option overwrites it with a valid one. I wonder if the problem would come back if you loaded factory default settings?

 

I'm not going to press my luck. lol. I'm happy it works. Almost done setting it up with my necessary tools and configs for work next week.
