I have a mid-2008 workstation with two HD monitors supporting HDMI and DVI inputs. Since Ubuntu 11.10, I have experienced no end of trouble with my NVidia Quadro NVS 290 in TwinView dual-monitor output. Others have similar desktop TwinView woes. I want a new graphics card.
Previously I asked for a graphics card recommendation and response was Nvidia Geforce GTS 450… but really I'm looking for someone who has actually got a working dual-monitor desktop to tell me what card they use so I can get something that is known to work.
So please, people who have no-issues with their 64-bit Ubuntu 12.04 Unity 3D desktop spread across two HD-resolution external monitors (either DVI or HDMI connector), and who also run Google Chrome (which throws a spanner due to its own GPU compositing)… please let me know what graphics card you have so I can buy one.
Gathering Options
These seem to be the Nvidia cards featuring dual DVI. But they all seem to be gaming cards – what has dual-DVI, good support, but is not a massive gaming card?
- Nvidia GTS 450 (previously recommended) – 2x DVI
- Nvidia GTX 550 Ti (used by System76) – 2x DVI
- Nvidia GT 430 (used by System76) – 1xDVI, 1xHDMI
- Nvidia GT 640 (found on NVidia site) – 1xDVI, 1xHDMI (also GT 620, GT 630)
Has anyone had a good desktop dual-monitor Unity 3D experience with ATI cards?
Decision
I've decided to go with the Geforce GT 620, which is the successor to the GT 430 and GT 530 in the performance ranking. I don't want gaming power, and the 4xx and 5xx chips seem to be out of stock, so I'll just hold thumbs that the binary blob will handle it correctly because it's a GeForce chip instead of a Quadro chip.
Best Answer
I've bought the Nvidia Geforce GT 620.
The GT 620 is a 2012 card, and at the lower-end card so it's affordable, but still performant at 11.2 gigatexel/second fill rate - and it supports multiple monitors on the different outputs (HDMI, DVI, VGA).
So far it works fine. I've got two identical monitors one on the HDMI and other on DVI, and and the colors seem slightly different at factory default settings.
It seems the main thing is to avoid Quadro cards on linux - GeForce cards work fine.
