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.

      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.
