G-SYNC対応の4K液晶ディスプレイをAcerが発表。2014第2四半期発売予定で，日本市場にも投入計画あり
台湾時間2014年5月22日，Acerは，NVIDIAのディスプレイ同期技術「G-SYNC」に対応した世界初の28インチ4K液晶ディスプレイ「XB
G-SYNCに関しては4Gamerでも何度かお伝えしているが，簡単にいえば，ディスプレイデバイスのリフレッシュレートを動的に制御する技術のこと（関連記事）。対応ディスプレイと対応グラフィックスカードを組み合わせることで，画面表示の「カク付き」（StutterもしくはStuttering）や「テアリング」（tearing）のない，滑らかなグラフィックス表示を行えるようにしようという技術だ。
XB280HKの詳細仕様や製品写真はまだ発表されていないのだが，28インチサイズ・3840×2160ドットの液晶パネルを採用し，視野角は上下左右とも170度。入力インタフェースとしてはDisplayPort 1.2を備え，USB 3.0ハブ機能も用意されるようだ。
スタンド部分は，チルト（前後の回転，傾き）が−5〜35度，スイーベル（左右の回転，首振り）が左右60度。高さ調整やピボット（回転）機能も備えているという。
G-SYNC技術を利用できる世界初の4Kディスプレイとなれば，注目を集めるのは間違いあるまい。いち早く手に入れたいという読者は，発売を期待して待とう。
Editor's Summary:
Acer announces the new Acer XB280HK gaming monitor as the world's first 4k2k display featuring NVIDIA G-SYNC technology to provide stunning, ultra-smooth, tear-free imagery and rich colors for outstanding gaming experiences. It features Acer's flicker-less, low-dimming and ComfyView technologies that reduce strain on the eyes for smooth and comfortable extensive viewing.
Part of the new XB0 line of large gaming monitors, the Acer XB280HK is intended to be paired with enthusiast PCs for immersive, ultra high-end gaming. It features a spacious 28-inch LED backlit display with 4k2k Ultra HD (3840 x 2160 pixels) that's four times the resolution of 1080p Full HD, and presents stunning high quality images for outstanding visual enjoyment.
With a GeForce GTX-powered PC, NVIDIA G-SYNC display technology synchronizes the display's refresh rates to the GPU to eliminate screen tearing and minimize display stutter and input lag to deliver smoother, faster, more breathtaking gaming experiences. Scenes appear instantly, objects look sharper and more vibrant, and gameplay is more fluid and responsive providing gamers with significant performance advantages.
The Acer XB280HK builds in several features that take into consideration prolonged usage by heavy users such as programmers, writers, and graphic designers:
The Acer XB280HK features 170/170 degree viewing angles so that brilliantly-colored images can be seen from almost every angle. DisplayPort v1.2 transmits video signals and four USB 3.0 ports are conveniently located at the side and bottom of the display for connecting to keyboard, mouse or mobile devices.
The Acer XB280HK monitor is made with post-consumer recycled plastic and features a distinctive red ring on the base stand. The multi-functional ErgoStand allows the screen to tilt from -5° to 35° to ensure the best viewing angle; the base rotates 120° from left or right for easy screen sharing; the panel height can be raised by up to 150 mm for optimum comfort; and the screen pivots from horizontal to vertical for more viewing perspectives.
This eco-friendly monitor features a mercury- and arsenic-free panel, LED backlighting for reduced power consumption, and is ENERGY STAR qualified.
The Acer XB280HK starts shipping in Q2 in Pan America, EMEA, Japan, and Taiwan.
