- Re: Max Resolution for external Monitor via HDMI on Lenovo Y700? 10:11 AM meanwhile I bought a new screen with a 2560 x 1080 resolution an it works perfect.
- The GeForce 840M 2GB has 3.2 GB/sec greater memory bandwidth than the NVS 4200M, which means that the memory performance of the GeForce 840M 2GB is marginally better than the NVS 4200M.
I'm gonna buy a laptop for programing and gaming, just found some good Thinkpad T420 series laptops but none of them offer a gaming VGA. I know NVIDIA NVS series are not gaming VGA, but with NVIDIA NVS 4200M (1GB DDR3 memory, 64 bit, 48 Pipelines) can I: 1.
I've got a Dell Latitude E6520 and I'm using the E Port dock to get a DisplayPort output to plug into a Dell U2711 monitor.
The native resolution of the monitor is 2560x1440 and I'd really like to get it to that resolution.
I'm using the Nvidia X settings thing and I the highest resolution listed is 1920x1080. Is it worth hand editing the xorg.conf file maybe? Or am I just out of luck?
The graphics card (NVIDIA NVS 4200M 512MB) seems to be functioning ok. Unity and the composite effects are all working and pretty snappy.
I did have to disable something called Optimus in the BIOS but I gather this is just a power saving thing.

From what I understand, 'Optimus' is the technology, which decides, when to use the dedicated Nvidia graphics card and when to use the on-board intel graphics chip.

For now, Nvidia has no plans to support Optimus on Linux. This makes hardware acceleration impossible by the Nvidia adapter. However, Martin Juhl is working on an Open source alternative called Bumblebee (https://github.com/MrMEEE/bumblebee).
You might want to check out the Bumblebee project, it seems to me, that this is, what you need to use your Nvidia graphics card.
I had the same problem, my monitor would only output at 1600x1050. In addition the display port would not work and dual-link DVI only outputted the above resolution. What I ended up doing was updating the bios to revision A07. This resolved the display issue. Now I'm just trying to figure out how to get the docking station to work correctly (i.e. having the monitors switch on the fly).

When I upgraded to Ubuntu 11.10 I was able to select the full resolution in the nVidia settings dialogue and everything worked perfectly.
