LG 43UD79-B offers 42.5″ of 4K FreeSync goodness

A professional-grade monitor doesn't have to be all business. What's the fun of owning a finely-calibrated, high-resolution display if you never load up a round of Civilization every once in a while? LG seems to have this kind of versatility in mind for its upcoming 43UD79-B display, a 42.5" behemoth with professional credentials and a few perks that gamers might enjoy.

It bears repeating that yes, this is a 42.5" display. LG brags that the display sports the biggest 4K IPS monitor panel to come out of the company's labs. With a static contrast ratio of 1000:1 and brightness of up to 350 cd/m², the display checks off many display enthusiasts' boxes. We don't have much information on the 43UD79-B's color gamut, perhaps because LG has only released information about the monitor on its Japanese and Ukrainian sites. The company does advertise that the display will come calibrated from the factory.

So how about the 43UD79-B's gaming chops? Its 8-ms gray-to-gray response time is a bit longer than gamers prefer, but the monitor has a mode that can bring down this latency by outputting images without frame buffer processing. The monitor additionally supports FreeSync, albeit with a rather limited refresh range of 56 to 61 Hz.

The 43UD79-B can use picture-by-picture mode to display four different 1920×1080 images simultaneously. Accordingly, it has a lot of inputs. LG fitted two HDMI 2.0 ports, two HDMI 1.4 connectors, and a DisplayPort output. A trio of USB ports is along for the ride, one in Type-C variety. Thanks to DisplayPort Alternate Mode, the USB Type-C connector can also feed a video signal.

As it turns out, this mammoth display doesn't carry an equivalently large price tag. Interested shoppers can find LG's 43UD79-B display available for preorder at Adorama for $697. The display will arrive in Japan on May 19. LG has yet to announce availability for other regions.

    it has a display port output (or did I read that wrong)

    Asus has a 144hz+ @ 4k LG – lift your game.

    Acer does 4k @ 144 as well.

    Gosh, if this had better freesync/gsync functionality it would be great buy for me right this moment at that price tag.

    See, the price of these things annoys me.

    It’s clearly LG’s 43″ TV panel, only it’s much cheaper for them to make because they don’t need speakers and they don’t need anywhere near as much postprocessing logic – just a simple scaler and basic OSD.

    The thing is, I can get an LG 4K IPS TV for under $400 so why does this stripped-down version cost $700?

      If it was Gsync it would be easy to understand the price (as ugly as the Gsync premium is) but you’re right that this is puzzling. Chalk it up to a premium for being the first, I guess. :/

      I want Sony and Microsoft to enable Freesync in their consoles so this becomes a thing in TVs. I’ll bet a shiny nickel the capability is in that AMD hardware, just dormant. And 4K would have been the perfect opportunity for it, but they blew it. Customers are buying new TVs anyway, and the framerates are going be trouble.

      Boo-urns!

        Scorpio will do Freesync over HDMI. Who knows when we’ll get a TV or monitor that will work with it though.

          • CuttinHobo
          • 3 years ago

          Oh yeah! Now that you mention it, I remember the story here a while back. Since Sony also makes TVs, it’s in their own interest to lead the charge. 🙂 And of TVs start supporting Free sync that might finally get Nvidia to hop on as well. (Though I’d expect them to keep developing Gsync)

          Do it, Sony!

      The “smart” TV ships with lots of apps for online streaming services… that PAY the TV manufacturers to install their stuff on new TVs. It’s the same reason that PCs with bloatware installed have been cheaper than ones with clean installs for many years.

      Agreed to some extent but it’s not necessarily the same panel you get in the $400 TV. LG do make more than one panel.

    • jts888
    • 3 years ago

    These are the same panels that LG has been selling in 120 Hz UHD TVs for years (so you know sufficient T-Cons exist as well).

    What on Earth led them to ship this without 120 Hz over DP 1.3/1.4 support?

    “Its 8-ms gray-to-gray response time is a bit longer than gamers prefer, but the monitor has a mode that can bring down this latency by outputting images without frame buffer processing.”

    Huh?

    Disabling overdrive will increase the response time, not decrease it.

      • cygnus1
      • 3 years ago

      Why do you think frame buffer processing = overdrive?

        • psuedonymous
        • 3 years ago

        I’m not sure why frame buffering would have any effect on panel transition response time. If frame buffering is going on, then that would be [i<]on top of[/i<] the hardware response time of the panel.

    that freesync range might sound useless but it’s still way better than using vsync at 60hz

      • K-L-Waster
      • 3 years ago

      Doesn’t help you much if your 4K FPS drops to 50 or lower though — which is likely to happen until AMD releases a GPU that can consistently deliver 4K at higher than that.

        • Firestarter
        • 3 years ago

        well it’s not AMD’s fault that you can’t use a GTX 1080 Ti with this monitor

          • DancinJack
          • 3 years ago

          K-L didn’t say it was. That doesn’t prevent AMD from making a higher performing graphics card though.

          • spiritwalker2222
          • 3 years ago

          uhm, you can use Nvidia video cards with this monitor.

            • DancinJack
            • 3 years ago

            Not with Freesync…

          • K-L-Waster
          • 3 years ago

          True — but not really clear who they are marketting the FreeSync feature to at the mo’

    • Hattig
    • 3 years ago

    The Freesync range is pointless, it surely must be a mistake or miscommunication!

    Otherwise, nice monitor.

    [quote<]supports FreeSync, albeit with a rather limited refresh range of 56 to 61 Hz[/quote<] Unless this monitor can overclock the range well, I see this having very limited use.

    [quote<]The monitor additionally supports FreeSync, albeit with a rather limited refresh range of 56 to 61 Hz.[/quote<] lol. I guess they wanted the buzzword to sell some units.

      • DPete27

      5Hz VRR is laughable for sure. I have a hard time even believing that that’s all the panel is capable of.

        • psuedonymous
        • 3 years ago

        Panel, no. But controller, yes. For all the extra cost of G-Sync’s dedicated panel controller it isn’t just farted into the wind. With DP Adaptive Sync integrated into commodity panel controllers it’s cheaper to implement, but it also means it’s limited to the capability the panel controller already had available (i.e. as close to the absolute minimum capability as possible to keep costs down). Basically, it’s whatever clock swing tolerance the panel controller could already handle, but with a branding attached to it (and some cursory extra testing to ensure the panel controller can reliably handle the clock swing). For wider clock ranges, that means an ‘overbuilt’ panel controller is required.
        On top of that are extra features like variable pixel drive timings, which isn’t something a normal panel controller has built in at all (hence the propensity for some Freesync monitors to have streaking/blurring/under/overshoot at high-contrast edges in some cases where the frame time is varying).

          Thanks for this. I regret buying an AMD card now. I’d initially hoped to pick up a freesync display but most have huge caveats. The ones that don’t are barely any cheaper than their g sync counterparts
