Acer Launches First 4K Panel With NVIDIA G-Sync Technology On Board 64

Posted by Soulskill from the all-the-pixels dept.
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.

      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.

          What are the dead/stuck pixel rates acceptable on a TV? GGP asked about displays, not TVs. Although you can press a TV into service as a monitor, and it might even do the job well, the level of blemishes deemed acceptable in a TV is considerably higher than that of a computer monitor.

          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.

        You could almost say the same for Apple products back in the G3/G4 iBook/PowerBook series.

        When roughly two out of three came off the line defective and were immediately caught in testing and sent back for refurbishing.

    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.

      I'd say price point matter more at this point.

      I would prefer to have an Nvidia card and I would prefer to have monitor synced to the GPU.

      As is Adaptive-Sync may be a standard of DisplayPort 1.2a but even the new Nvidia cards only have DisplayPort 1.2 and who knows what Nvidia will do. It suck to get an Nvidia card if they are retarded and decide not to support Adaptive-Sync but I don't want anything else either because Nvidia make the best products. :/

      Good point... I'm all done with Nvidia and AMD. The only somewhat reliable graphics thing is intel. Next time I get a laptop I'll lookout and make sure I don't get something with one of nvidia's proprietary solutions... Currently stuck without external display because it runs over nvidia optimus; which is utter shit in any configuration under linux.

      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

        I don't think that's true, a monitor will outlast a video card by years and years. The difference between G-sync and Adaptive Sync is that if people start buying monitors with Adaptive Sync Nvidia will start supporting them. Everybody wins. (except Nvidia's bean counters)

        AdaptiveSync is part of the VESA standard. If they want to be able to claim compliance they have to support it now.

        It's been an optional extension forever, but with Displayport 1.2a and up it's now mandatory, making any money spent on the sub par and over priced G-Sync panels irrelevant.

    • It will probably be a year before any monitors come out with the VESA standard Adaptive Sync. You can get GSYNC monitors now.

      I used the GSYNC upgrade kit on my VG248QE in January and since experiencing GSYNC I could never go back. Everything is much smoother at all frame rates without stuttering or tearing or any of the added input latency standard VSYNC adds.
      I can't wait for non-nvidia support, but it is a long ways out.

        AdaptiveSync doesn't require the specialized hardware, just a Displayport 1.2a or newer monitor and GPU. Since the Displayport 1.3 spec is also now out expect that to be where the next gen hardware to be for 60Hz+ 4K and support for resolutions up to 8K. https://en.wikipedia.org/wiki/DisplayPort#1.3

  • That is a really good price for 4K. I guess you are comparing it to 1080p, but since the article and your post was about adding G-SYNC to a 4K panel, I'm not sure why you'd do that.
    • The note was versus "standard 28-inch panels"... not 4K. Yes, this is a solid price for a 4K 60Hz panel, with or without G-Sync. However, you can get standard 28-inch panels for a lot less and even Samsung, Dell and Asus non-G-Sync 4K panels for as little as $429 to about $600 now.

      Yes, that's a premium price for a 28" 4K display. Dell is currently selling theirs for $430. Note, though, that the relatively inexpensive 28" 4K displays are using TN rather than IPS, which is a big reason they're relatively cheap.

  • Gee, what a surprise.

  • Come on since when does a price for a stupid TN panel matter?
