Graphic card for running three 22 inch monitors

Are there any good graphic cards which would not have this VPU recover and would fit in the 790 mini tower? Perhaps, next time I should get those for such uses. From a technical perspective, I would personally prefer to handle it with a single card. That is, as long as the monitor orientation is panorama 1x3. I understand you can use one of the other monitor outputs as a "random" non-Eyefinity monitor, so if you wanted to arrange the three monitors in the letter "L", you could. Your idea of using two monitors is fine, except for two things. 1) Greater potential for one monitor to update 30ms after the other. 2) Possibility OS will randomly swap the purpose of the two video cards, such that the left monitor becomes the right monitor and vice versa. I wouldn't mention this, except it happened to me. I don't really know how prevalent Display Control Panel issues are with multiple video cards. If you had a 5450, then I'd probably buy a second. If the 5450 was doing VPU reset, I'd buy a couple cheap NVidia cards to replace it. Sometimes you can get cards for $30 to $50. Back-to-School is coming soon, so expect prices to be headed in the wrong direction. A few things for computers are under supply pressure. We're short of Flash. We're short of DRAM. On video cards, the high end cards are being used to mine Ethereum. But that should leave the $30 cards for your experiment. (A 710 with a fan on it. $38) https://www.newegg.com/Product/Produ...82E16814125900 That one has DVI-D not DVI-I. There are no VGA signals on the DVI connector. You could use a "DVI to HDMI out" adapter on the bottom connector, for 1920x1080. Otherwise, the card may simply not have the resolution options needed for your project. Getting max connector flexibility could cost $200. For that price, you could likely drive quite a variety of monitors. But that card probably wouldn't be that good a choice for a machine with a teeny tiny PSU. As long as you check the specs, you've made sure you have the right connectors for the three monitors (or an adapter or two to cover off that requirement), I'm sure you can whip something together. My main concern then would be with the (1) behavior. Even when you use two heads on the same video card, they could end up out of phase. Whereas with Eyefinity 1x3 panorama mode, they'd be aligned in time (since they're actually coming off a single head just before the crossbar). This doc has a picture of the crossbar. See page 8. It takes a few seconds for the picture on page 8 to render so be patient. https://web.archive.org/web/20061126...Whitepaper.pdf For Eyefinity, you'd be using the top block on the left, and then using three connectors on the right (off the crossbar). A single head generates 5760x1080, and the crossbar does "Matrox triple head" style chopping, to make three 1920x1080 outputs. That's how Eyefinity would differ from the generation in that document. Paul Thanks Paul, The card you mentioned https://www.newegg.com/Product/Produ...82E16814125900 is out of stock, but I will try that. I appreciate all your advice and help. |

It almost feels like Nvidia is going to replace that with something. Maybe they could rebrand those chips again and make "new" models ? The price on this one is higher. https://www.newegg.com/Product/Produ...82E16814487371 I notice comments on some of the other cards, with regard to instability. There's no reviews listed for that particular card. I'm selecting 1GB cards here, because the 2GB appear to be less stable, and with the 1GB cards, if you were using a 32-bit OS, there'd be a tiny bit of address space left. This project is going to work best, with a 64-bit OS. Paul |
