How DisplayPort multi-streaming delivers new levels of multi-monitor madness - blackcomentse

When a vender sends us a present arrangement, it typically look at of import care to check that we experience the system exactly as the maker intends us to. So when VESA, the craft group trusty for the DisplayPort standard, said that it was sending PCWorld a multiple-monitoring device demo organization similar to the one IT exhibited at CES in January, I expected it to come bundled with a detailed guide and complete the computer software needed to present DisplayPort in its best light.

Imagine my surprisal when an MSI GX60 gaming laptop, two 24-inch Dell U2413 displays, and a 21.5-inch H.P. Elite L2201x showed ahead in the PCWorld Labs without so a good deal every bit a user manual for any of the four devices. "Wow," I thought. "They must be pretty certain that setting all this up will be self-evident."

The Mini DisplayPort connector is located connected the MSI GX60's rear panel, between the VGA and HDMI ports.

As things turned out, setup waspretty much ego-observable. The GX60 has HDMI and VGA video outputs, but obviously I was more interested in its Mini DisplayPort. Some of the Dell monitors have entire complements of extremity video inputs (HDMI, DVI, and full-size DisplayPort, along with ports labeled 'DisplayPort In' and 'DisplayPort Forbidden'), but the HP expose has only a DisplayPort stimulant.

I connected the heavy-size up DisplayPort on the first Dingle to the notebook, obstructed a secondly cable to that monitor's DisplayPort Out, and related to that to the other Dingle's DisplayPort In. So I attached a third cable to the second Dingle's DisplayPort Out and plugged IT into the HP display to complete the string.

The notebook was now driving four displays, including its possess. This setup was assertable because all of the gear—except the HP at the end of the chain—verified DisplayPort's multistreaming feature. And so if you'Re thinking of scrounging up threesome old DisplayPort monitors and duplicating my experience, you're taboo of luck. Then again, you can press nonpareil old monitor into service (if information technology supports DisplayPort, and if you install information technology at the end of the chain). DisplayPort is a common feature on white-collar and business monitors, but it shows up very much less oftentimes connected consumer displays.

I hope that changes, because DisplayPort rocks.

The monitors you enjoyment don't have to be the indistinguishable size, and they need non support the same result. As I found out later, that's why VESA transmitted us two models (the Dells) that had a inborn resolving of 1920 by 1200 pixels and one (the H.P.) that had a pure solution of 1920 by 1080 pixels. The laptop display at the beginning of the chain also has 1920 by 1080 indigene resolution, but the monitor at the other end doesn't give birth to be positioned last in the array.

Presented with nearly 6 feet of horizontal display space, I plant that I didn't motive to use the laptop's expose at all.

Since the HP monitor was littler than the other two, I put it in the center of my field of view and arranged the Dells along either side. I moved the notebook off to one side (with a USB creep and keyboard plugged in), and victimized it to park windows—so much as my appointment calendar—that weren't my current focus. I found that having my Windows desktop arrayed across three autarkic monitors was a tremendous boon to my productivity. I almost never had to waste precious time resizing windows as I multitasked, and I had solitary to pivot my head when an email or chat window commanded my essential focus.

Here I have 'The Hobbit' running connected one screen, information or so the film from the studio on a second display, and an online game version on the 3rd.

When I switched complete to playing games, however, I turned the notebook's 15.6-inch display off, because it was too disproportionate to the other three screens. Though I could have added a fourth large display to the mix, doing so would have left a bezel in the middle of my view. That wasn't an issue when I was in a productivity environment, because I never spanned a single covering windowpane across more one exhibit.

The gaming live

Acting games on three midsize displays is mind blowing. Newer titles, including Crysis 3 and Bioshock Unlimited, support the unusual resolutions that much arrays require. In this case, I ran some of them at 5760 by 1080 pixels (1080 being the lowest plebeian denominator in terms of height of the three monitors I was using). The games filled my entire field, immersing me in their environments like zilch I've ever experienced clipped of wearing a head-mounted display—but without the inconvenience of having my noggin tethered to my computer. Using three identical displays would have yielded an even better experience because I could have concealed the bezels on the left and mighty monitors more effectively behind the ane in the center. (Samsung once configured and built monitors—the fellowship's simulate MD230—specifically for this application program, but information technology no thirster manufactures them.)

I was able to manoeuvre Bioshock Infinite at 5720 by 1080 resolution, with every its outstanding visual effects intact.

Though I had to telephone dial down Crysis 3's visual effects to 'medium' to render the brave playable, I turned happening antialiasing and cranked Bioshock's texture detail and texture filtering settings to 'ultra' and had a perfectly enjoyable experience. The game's intrinsic bench mark produced an average frame rate of 26 frames per bit at those settings, with a uttermost of 48 fps and a minimum of 7 fps. Nip gamers bequeath grouse that anything less than 60 fps is an unacceptable level of operation, but you can get close to that magic number away reducing the demands on the GPU at the disbursal of the crippled's surprising visuals.

Reality check

Making the most of DisplayPort 1.2 and its multistreaming feature entails a significant investing. DisplayPort is a popular feature connected business concern-oriented laptops and desktops, just you won't find it on a typical all-in-same PC. Withal, AMD and Nvidia have jumped along the DisplayPort bandwagon with much to-do. You'll discover multistreaming DisplayPort connectors on whol video cards supported AMD's Radeon 7000 series and Radeon 8000 serial GPUs (as asymptomatic as on well-nig cards based on its Radeon 6000 series chips), and on all video recording cards supported Nvidia's GeForce 600 series and Quadro series processors. Intel's coming Haswell series CPUs will support multistreaming DisplayPort, too.

Even if you already have the right connections happening your calculator hardware, you'll likely need to buy new displays to get DisplayPort multistreaming, and such displays don't derive cheap. The superior Dell U2413, e.g., costs about $600. If I could afford it, I'd happily invest in three daisy-chainable displays that possess the same dimensions and resolution—merely doing so would want more mint than I'm prepared to contribution with right now. Net ball's desire the display industry embraces multistreaming DisplayPort in a bigger way and introduces more consumer-oriented models soon. As I said earlier, DisplayPort rocks.
