Can a 7710 with M5000M dGPU output to a 5120x1440 display


Recommended Posts



I'm considering purchase of a super ultra wide 5120x1440 display for my 7710 laptop.


The 7710 laptop has NVIDEA M5000M GPU, thunderbolt 3 port, and mDP.


I've an advance E-Dock having two display ports.  For years I've used the 7710 to output to Two 2560x1440 by using the Advanced E-Dock's two display ports.


I've given my two 2560x1440 displays to my father who also has identical 7710 and Advanced E Dock (his 7710 internal display is currently broken so he needs the displays more than i do now).



Dell notes say the 7x10 series can output to a 4k display, but doesn't say anything about 5120x1440 resolution because i don't think there was such in 2015.




I'm shopping for new external display -


I'm looking at 49" LG Super Ultra Wide 5120x1440 display.  It's basically equivalent of two 27" 2560 displays.


Does anyone know if my 7710 may be able to output to that 5120x1440 resolution using a single DP or mDP or even a thunderbolt 3?


The LG can take dual inputs so maybe i could output using the two DP ports from the Edock.


Else i may go with a regular 4k format in 40", but I'd prefer super ultrawide so my neck doesn't have to adjust to looking up so high.


Thank you,

I think it's basically just a matter of display bandwidth.  Dell doesn't set particular resolutions as allowed or not allowed.  That's more up to the GPU driver.


Precision 7710 can output to a 4K display at 60 Hz.  (I have personally done this on Precision 7510, both over mDP and through the TB16 dock.  WD15 dock can drive it only at 30 Hz.)


4K is approx. 8.3 megapixels.  Your ultrawide display is just 7.4 megapixels.  The bandwidth is there.  I think it should work.

Thank you Aaron, that is reassuring.


I'll be ordering through Amazon.  If for some reason it doesn't work, they are easy to refund or return.


*Edit:  it works great -I posted another thread in the display monitor section of the forum with photos of the display and it working.
