Sharp Ultra HD 4K Monitor

Simple, Advanced Interface

The PN-K321 supports both DisplayPort™ and HDMI™. 4K Ultra-HD video signals can be transmitted via a single easy-connecting, clutter-reducing cable.

MST Mode for 4K Ultra-HD Video at 60 fps

The PN-K321 supports MST (Multi-Stream Transport) mode as specified by the DisplayPort 1.2 standard. A single DisplayPort cable can transfer 3,840 x 2,160 video signals at 60 fps, resulting in smooth rendering of high-resolution video and fluid mouse operation.

Built-In Speakers

Built-in speakers eliminate the need for external speakers and keep the PN-K321 stylishly streamlined. The speakers emit sound from both sides of the monitor, making them ideal for conveying audio information.

Sharp Ultra HD 4K PN-K321 LCD monitor heralds an entirely new generation of displays that incorporate Sharp’s cutting-edge IGZO* technology. This technology offers two major advantages: extraordinarily high resolution and energy efficiency. At 3,840 x 2,160 pixels (4K Ultra-HD), the PN-K321 boasts four times the resolution of 1080p full HD. Users can now view the content of four full HD screens on a single, seamless display. This super-high resolution makes the monitor ideally suited to a wide range of professional applications in settings where detailed information needs to be displayed with tremendous precision. IGZO technology supports increased pixel transparency and reduced current leakage, resulting in lower power consumption.

Thin and Stylish

The PN-K321 owes its stylish and slender design to IGZO technology and edge-lit LED backlighting. Measuring only about 35 mm at its thickest point, this sleek and lightweight monitor blends in effortlessly in almost any location. The PN-K321 comes with a stand and offers a choice of landscape or portrait installation*, allowing users to select the mode that best suits their display content and application.

4K Ultra-High Resolution

The small size of semiconductors made with IGZO technology enables smaller-sized pixels, which in turn provide stunning high resolution.
