One Video Card, 12 Monitors

Jamie found a story that might make your jaw drop if you happen to have some need to put 12 video cards in your machine. Although if that isn't enough, you can always install two of these. I don't think I'm kidding.

    I think a 4 or 6 core CPU could support 12 users in many cases. I could see building a computer lab at a school this way to minimize administrative burden. But it's too bad multi-seat linux doesn't work better. I have struggled with it on and off over the years, and it just doesn't seem to have critical mass of interest to gain real distro support.

      Because of that you'd save little, if any, money over cheap systems acting as thin clients

      Good detailed technical analysis, but I can get an equally valid argument by working a different angle.

      Unless you're doing something real weird/wrong, the cheapest part of a computer lab is the hard drive, video card, chassis, etc. Zero that out, and you've got something very unusual, rare, and complicated, yet remains at 99% of the total cost, that being mostly salary and indirect costs (health insurance, pension, etc) and stuff like HVAC, electric bill, fractional capital expense of the building, cost of electrical and LAN wiring and related hardware... If you want to save a whopping 1% of the total cost of ownership, the very superficial answer is just install 99 computers instead of 100.

      If your 24 room school costs $12M to build, which seems believable, then your empty room cost $500K. You can pull your hair out to "save" $2500 worth of hard drives and $1250 worth of chassis/power supplies, but that's a false economy. And you'll never be able to piecewise upgrade.

      THat is an amazingly odd way to try and squeeze more simultaneous users out of one box. FIrst you take a four or six core CPU, add an ungodly-expensive video card, and then (I assume) a couple dozen USB ports for keyboards/mice THEN you get to write the glue software to make it all work together.

      Exactly how would this be more useful than a dozen Atom-based systems at $200/each (plus monitors/keyboards/mice, common requirement for either your solution or mine)? Assuming the appropriate software exists (and I don't think it does), if the main unit goes down, all 12 users are SOL, but with my RAIPC (Redundant Array of Inexpensive PCs) you can keep working until all 12 systems go down!

  2. Only one problem by Pojut · · Score: 3, Insightful

    Once you go past a three screen Eyefinity setup, Bezels become a real serious problem. With three displays it's no big deal, since the center monitor serves as your primary view while the other two monitors expand your peripheral vision...but with 6 monitors, you will have bezels crossing the center of your point of view, making things real wonky.

    Yes, it's awesome having the size, but until someone releases a bezel-less six monitor system, it's kind of a waste of time. Besides, with how much a six monitor setup would cost, you may as well buy a good quality projector.

    Realistically how many different displays can the average consumer use at a time? Gamers might want 3 or 4 and then they are landscaping them so that they can see left, center, and right. Given that and the cost (both monetary and performance) of adding more displays to a card, means that I think 2 is about right. For specialized applications like store displays, etc, more displays is better but it is not a high volume market.

    The summary is poorly worded. ATI's Powercolor HD5970 video card supports 12 display outputs. If you have two, you go up to 24 display outputs. At that point, you could monitor the whole of the matrix.

    1. Re:Matrox? by fuzzyfuzzyfungus · · Score: 3, Informative

      In terms of number of outputs, Matrox has indeed been doing it for years. The difference is that their gear tends to be fairly expensive(particularly when you consider its brutally tepid performance) niche stuff. According to their price sheet, their 8-head will run you $2K. Their cheapest quad-head is $330. And these are for display controllers that are basically suited for 2D applications.

      By contrast, the ATI stuff, with vastly superior GPU peformance, and typically more RAM, is cheaper. 5-heads will run you $220. 6 will run about $500; because you can't seem to get 6 without a 5870, which isn't a cheap chip.

      This 12-head monster, since it is probably a relatively short-run enthusiast catcher, may well land in the ~$1000-~$1500 zone; but that will still make it cheaper, faster, and with more heads and RAM than the Matrox equivalent.

    I haven't really checked modern chipsets, but some older nvidia models definitely had a performance drop.

    My preferred setup is one larger horizontal display for environments which require directx/opengl. That is paired with a second vertical display which usually has non-interactive statistic and monitoring applications running.

    There was a significant drop in performance regarding the accelerated output and unless there is a specific chip driving each display I suspect this will always be true. However, given the advancement of video controllers today it will likely be less of an impact as performance increases. Specifically, I don't recall noticing an impact on my now defunct GT 290. However, being defunct and sitting on my coffee table I can no longer confirm.

    As a person more or less forced to use two at work, I hate it with a vengeance because it's all one big virtual desktop because of citrix and every application feels like popping up dialogs across the middle. Three would be infinitely much better than two, at least there no "#%5%%%#"# bar dead center. I know you can do that with a regular Radeon 5xxx if you have DP displays or an active converter, but I'd love to see it become standard like double DVI ports have been for a while.

    If I could hook up 12 picture frame monitors in various rooms of my house, that would be fun.

    I just want to drop .jpgs into certain folders on my pre-existing file server and have the pictures randomly displayed thru the house, shuffling perhaps every 10 minutes. Also I'll have certain webcams periodically downloaded and added to the mix. And a cron job to display certain pictures at certain times, etc. A couple lines of perl, bash, and wget, thats what I'm talking about.
