JapanNext has started to sell its new ultra-large 49” and 55” curved displays that feature an Ultra HD resolution, a low response time, AMD’s FreeSync dynamic refresh rate technology as well as HDCP 2.2 copyright protection. The monitors are not too expensive: they are currently available for less than $900.

Ultra-large displays are not so common but are not something extremely rare too. For example, companies like NEC offer displays with 40”+ diagonals for professional and industrial applications. Such monitors tend to be too expensive for personal use because they are built according to different standards asking for 24/7 operation and rated for maximum endurance. For many people displays larger than 40” are simply too big, but there are gamers as well as those need to keep a lot of information on their screens, who may want to have a huge monitor. Last year TPV (Philips) introduced two 40” and 43” UHD 4K monitors for prosumers that retail for less than $1000. This month a Japanese company called JapanNext introduced its JN-VC490UHD and JN-VC550UHD monitors that are even larger and support a dynamic refresh rate technology.

The JapanNext JN-VC490UHD (49”) and JN-VC550UHD (55”) displays are based on SVA panels (which may indicate that the manufacturer sources it from Samsung Display) with a 3840×2160 resolution, 250 nits brightness, a 6000:1 contrast ratio, a 60 Hz refresh rate and a 3-4 ms response time. The producer states that the display panels can reproduce 1.07 billion colors (listed online as 10-bit) and are rated to support 99% of the sRGB color gamut. The displays use ELED backlighting to ensure “flicker free” operation and JapanNext promote the panels as being 16mm thick.

In a bid to make the JN-VC490UHD and JN-VC550UHD monitors more appealing to gamers, JapanNext equipped the display with AMD’s FreeSync dynamic refresh technology (and there is AMD’s official FreeSync badge on the manufacturer’s website). Unfortunately JapanNext does not declare what refresh range it supports for FreeSync, which may be limited (40/45Hz to 60Hz or similar). Moreover, the units both fully support HDCP 2.2 technology, which is not common for monitors, but which is more commonly found on UHDTVs (given the dimensions of the JN-VC490UHD and JN-VC550UHD, it makes sense to compare them to TVs). Therefore, the 49” and 55” curved UHD displays could be used for Ultra HD Blu-ray playback (but HDR support is not formally declared however).

Connectivity is a yet another interesting peculiarity of the JapanNext displays. The monitors have two HDMI 1.4 inputs that support 3840×2160 resolution at 30 Hz, one DisplayPort 1.2 and one HDMI 2.0 that can both handle 4K at 60 Hz as well as one D-Sub connector (up to 2560×1440). The displays support PiP (picture-in-picture) and PBP (picture-by-picture) modes and some may use it to work with up to four different FHD PCs. As for audio, the displays are equipped with two 6 W stereo speakers, a 3.5-mm audio input, a headphone output and an SPDIF optical output for those who will use them with an audio decoder/receiver.

The ultra-large curved UHD displays for prosumers and gamers from JapanNext will attract attention from many people who primarily need large dimensions. While the pixel density of the JN-VC490UHD and JN-VC550UHD monitors is comparable to that of 24” and 28” FHD screens, it does mean that applications that lack high-PPI settings may not be disadvantaged on the new displays (it depends how close you sit). JapanNext makes no secret that many people will use its new products primarily to enjoy media content in their living rooms: because the TVs have so many inputs, users can attach multiple STBs to them. A bad news is that the devices only have one HDMI 2.0 header, so owners will have to choose whether to plug in one high-end HDMI 2.0 device.

The official price of the JapanNext JN-VC490UHD is ¥99,970 ($873), but Amazon.co.jp offers it for ¥82,970 ($725). The MSRP of the JapanNext JN-VC550UHD is unknown, but it is available for ¥99,970 ($873).

The manufacturer sells some of its displays in Europe via its own website, but the lineup there is not too wide. It is unknown whether JapanNext plans to make its JN-VC490UHD and JN-VC550UHD available outside of Japan.

    I have the same Samsung display at 40". You can calculate the angular resolution at in PPD (Pixels Per Degree) --> Tan(.5) * 2 * 110.15 * 30 = 57.67. That's 57.67 pixels in one degree of angular measurement sitting 30" from the screen with 110.14 DPI. By Apple's definition that is a 40" 4K Retina Display. And I don't use any DPI scaling - running at 100%.

    Other sizes might work well...like the 42.5" Sony X800D and 48.5" Samsung KS8000, which are higher-quality TVs. But you'll have to push the display back another 2" and 6" respectively to keep the angular resolution above 57 PPD. You may have to buy a wall mount or VESA stand or a deeper desk. I think that a curved display would help mitigate the larger sizes, but 40" and 42.5" are OK even when the screen is flat.

    Response time, resolution, size, HDR features, and price make this a great product on paper. The rest of the monitor industry needs to catch up. There is absolutely no way I'm dropping $500+ on an outdated, and under-spec'ed PC monitor now. Acer, Asus, and Nvidia can keep dreaming. Their stuff is just looking more ridiculous each day.

    Would really like reviews of some of these http://www.rtings.com/tv/reviews/by-usage/pc-monit... by a you guys at Anandtech.

    Nice but eyeing for a 120Hz capable 4K screen.

    Been doing a lot of research on this lately. With an EVGA GTX 1080 FTW Hybrid on order (nvidia is my choice and I'm not budging) I've decided as of this month on the Sung KS8500 line. Why?

    Let me count the whys!
    A) It's a dumber version of the 9000 line, less audio, slightly less hz rate, but still 240hz (100-120 actual so says most TV reviewers following the CMR divided by two rule of manufacturers)
    B) 120? don't whine! People achieved good FPS on screens that were "labeled" 120hz which by the law of halves was really more like 60hz - and they still did pretty good as gaming TV's.
    C) At this site, the KS8500 scores slightly better than both the 9000 and 9500 versions.
    D) All Samsung TV's in the 8000 and 9000 class (maybe 7000 or below? Idk) feature quad-core processors... which leads to my next point.
    E) For those older 2013-era TV's that don't... Samsung developed this sucka...
    which raises speculation. Since the HDMI 2.1 and DP equivalent standards that support adaptive sync still depend on the input source having VRR (someone correct me if i'm wrong here) so they are helping to provide the tech for the TV while mfg's produce VRR ready source devices. ?! I think. Why else make an upgraded box... aside from the extra features vs the one that is included in US TV models.
    F) I just read tonight that some top guy at Nvidia said that they might consider supporting Freesync if enough of the public wanted it. Well DUH all Nvidia 10 series cardholders want it, and people will want to upgrade to it if they can use that Samsung One Connect box to upgrade older TV's to have adaptive refresh.
    G) Because.... HDMI 2.1 specification announcement material.
    H) Sung KS8000 / 9000 TV's might get 2.1 support via either firmware or their upgraded box, or both. OR they'll be stingy and release it on other TV's.
    I) Because quantum dot. And I can save $2000 not having QLED and upgrade to that when its one or two generations old.
    J) Because I think 4k will plateau, even though there is this chatter of 8k at 7680x4320 because WHAT HARDWARE WILL BE SUPPORTING THAT AND NOT CATCHING YOUR HOUSE ON FIRE!?? Yea. Quad SLI GTX 1200's or 1400's or whatever we will have by then, after you paid Nvidia for TWO unlock codes and a special order solid gold plated SLI bridge. Oh yea, or AMD's sad equivalent.
    K) Hm. Price for size.

    L) also, I use an older Sung UN40FH6030 for graphic/web design, video editing, entertainment, PC and Xbox gaming and it handles Crysis, FarCry, Warframe and World of Tanks HD all on ultra settings at better than 50fps on my old GTX 670 FTW with a 15% OC and i5 3750k OC'd to 4500. So this TV does good with some gfx power behind it. With an input lag of 75ms maybe 60 when I optimized it? The 8000 line has an input lag of closer to:
    1080p @ 60Hz: 23.1 ms
    1080p With Interpolation: 130.4 ms
    1080p @ 60Hz Outside Game Mode: 123.2 ms
    1080p @ 60Hz @ 4:4:4: 39.5 ms
    4k @ 60Hz: 19.2 ms
    4k @ 60Hz @ 4:4:4: 33.4 ms
    4k @ 60Hz + HDR: 19.2 ms
    4k @ 60Hz @ 4:4:4 + HDR: 33.2 ms
    All what I consider very fair numbers - STOCK. Those will improve when both the TV and Input Source is optimized.
    Which makes me optimistic.

    > HDR Support not officially declared

    dealbreaker right there
  • praeses - Friday, February 17, 2017 - link

    Cut the panel in half horizontally for 3840x1080 and double the refresh rate to 120hz (same throughput pretty much) and even at the same price for half the panel area I'ld be game.
  • DaFanMan - Tuesday, February 21, 2017 - link

    If the 49" was available in the States for around $700-750 I'd 100% give one a try - on paper looks like a very compelling option. I was considering a KS8000 or KS8500 but would really like FreeSync even if it only provides a 15-20fps window that would still be super helpful. Sadly it doesn't seem like Amazon.co.jp or JapanNext ships to the US.
