Acer Launches First 4K Panel With NVIDIA G-Sync Technology On Board

MojoKid writes: Save for a smattering of relatively small, 3K and 4K laptop displays, we haven't quite gotten to the same type of pixel density on the PC platform, that is available on today's high-end ultra-mobile devices. That said, the desktop display space has really heated up as of late and 4K panels have generated a large part of the buzz. Acer just launched the first 4K display with NVIDIA G-Sync technology on board. To put it simply, G-SYNC keeps a display and the output from an NVIDIA GPU in sync, regardless of frame rates or whether or not V-Sync is enabled. Instead of the monitor controlling the timing and refreshing at say 60Hz, the timing control is transferred to the GPU. The GPU scans a frame out to the monitor and the monitor doesn't update until a frame is done drawing, in lock-step with the GPU. This method completely eliminates tearing or frame stuttering associated with synchronization anomalies of standard panels. There are still some quirks with Windows and many applications that don't always scale properly on high-DPI displays, but the situation is getting better every day. If you're a gamer in the market for a 4K display, that's primed for gaming, the Acer XB280HK is a decent new option with this technology on board, though it does come at a bit of a premium at $799 versus standard 28-inch panels.

    The problem is that G-sync is a proprietary solution by Nvidia.

    Whereas, Adaptive Sync is a VESA standard officially part of the DisplayPort 1.2a specs.

      As for the monitor manufacturers, I'm pretty sure they are on the passive end of this - customers choose graphics card first, then a screen that works with that card. So while it is a standard, I doubt consumers will care. nVidia is the top dog, with GTX 970/980 they gave AMD another kick to the balls and they're in a position where they can choose to be the MS Office of the market. How far as OpenOffice's standards compliance gotten them in dethroning MS Office? Not far, around here at least.

    Mod parent up. I was trying to hunt down last night what tab in Firefox was outputting audio at me. It turned out to be slashdot. BAD SLASHDOT! Keep this up and I will hit that disable advertisement which I have the option to do. I go ahead and let them serve me ads which I would never in a million years actually click on, because I know they get paid for impressions and I feel they deserve some money for hosting the site. But forcing me to have to listen to the audio of some advertisement that clearly makes no sense without the video and without prompting to be played, when for all they know I could be trying to videoconference with the CEO or something? That is just wrong.

    All I want is a 35"+ 4k display with a 60hz refresh rate for under $300. Is that so much to ask?

    Yes, it is, at least with current manufacturing capabilities. Small high-density screens are exactly that -- small. If you have one defect every 30 cm (linear) on average, this may affect one screen out of five -- and even then, there's still some non-critical use where that screen will be just fine. (The front panel of a radio, for example.)

    If you're trying to produce large panels with that same defect rate, your rate of defect-free panels is going to be astonishingly low, and there won't be much of a market for the defective ones. Even if Yamakasi is willing to buy and package them, it hurts the image of 4k in general that they hit the streets at all.

    This high failure rate means the panels are going to be expensive, because you're not just paying for the one you get. You're also paying for the ones that didn't make the cut.

    The 39" Seiki TV is a good shot across the bow of your argument. 60 Hz refresh in a proper monitor format is coming next year, but for now you can pick up the current TV version for $340 shipped from Amazon. I think the next 12 months will bring a big shift to 4k the way we went from CRT's to LCD's in an amazingly short window.

    I could be. I could be doing any number of things including reading slashdot for 5 minutes during my lunchbreak and then leaving the tab open but not ever looking at it again, and my boss could come in and wonder why there are ads playing on my laptop.
    Technically, we are not allowed to be streaming audio or video, so slashdot is causing me to violate company policy if they autoplay the ads.

    The 39" Seiki is two panels side by side, not one panel. There are defects easily exposed when using this TV as a monitor. It is truly horrible in that application.

    Those cheap 4k TVs aren't really worth it though. They use panels that fail on things like colour quality and uniformity. You would be better off getting a 2k TV with good panel and processor.
