ygohome Posted November 30, 2022 Share Posted November 30, 2022 Hello, 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.

Aaron44126 Posted November 30, 2022 Share Posted November 30, 2022 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. 1 Apple MacBook Pro 16-inch, 2023 (personal) • Dell Precision 7560 (work) • Full specs in spoiler block below Info posts (Dell) — Dell Precision key posts • Dell driver RSS feeds • Dell Fan Management — override fan behavior Info posts (Windows) — Turbo boost toggle • The problem with Windows 11 • About Windows 10 LTSC Spoiler Apple MacBook Pro 16-inch, 2023 (personal) M2 Max 4 efficiency cores 8 performance cores 38-core Apple GPU 96GB LPDDR5-6400 8TB SSD macOS 14 "Sonoma" 16.2" 3456×2234 120 Hz mini-LED VRR display Wi-Fi 6E + Bluetooth 5.3 99.6Wh battery 1080p webcam Fingerprint reader Also — iPhone 12 Pro 512GB, Apple Watch Series 8 Dell Precision 7560 (work) Intel Xeon W-11955M ("Tiger Lake") 8×2.6 GHz base, 5.0 GHz turbo, hyperthreading ("Willow Cove") 64GB DDR4-3200 ECC NVIDIA RTX A2000 4GB Storage: 512GB system drive (Micron 2300) 4TB additional storage (Sabrent Rocket Q4) Windows 10 Enterprise LTSC 2021 15.6" 3940×2160 IPS display Intel Wi-Fi AX210 (Wi-Fi 6E + Bluetooth 5.3) 95Wh battery 720p IR webcam Fingerprint reader Previous Dell Precision 7770, 7530, 7510, M4800, M6700 Dell Latitude E6520 Dell Inspiron 1720, 5150 Dell Latitude CPi Link to comment Share on other sites More sharing options...
ygohome Posted November 30, 2022 Author Share Posted November 30, 2022 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.
