Today’s office professionals are especially keen on curating their workspace to meet their needs. Many now find themselves working from home either temporarily or permanently. One of those adaptations involves the use of a second monitor to extend their laptop screen so that they can multitask easily, connect quickly, and view images clearly. The video cables on second monitors can quickly clutter up desks, however.
The HP U27 4K Wireless Monitor solves that problem. It provides for clutter-free, wireless PC monitor sharing that's perfect for both work and play requirements. Let’s take a look at it in more detail.

The HP U27 4K Wireless Monitor is the world’s first 4K wireless sharing PC monitor. It’s perfect for both work and entertainment; delivering productivity, multitasking, flexibility, and connectivity capabilities.
Most monitors require video cables that limit mobility and add to cable wire clutter. The HP U27 4K Wireless Monitor lets you connect wirelessly via a USB-A port that works to provide clutter-free, quick, and seamless connectivity. You can connect wirelessly or via wires to share photos, videos, and more. Enjoy the freedom to work or play from anywhere in the room.

Before we take a deeper dive into some of the key features and benefits, let’s define what the HP U27 4K Wireless Monitor is in broad terms.

What is a 4K monitor?

A 4K monitor has Ultra High Definition (or UHD) resolution featuring a dimension of 3840 x 2160 pixels – that’s 8.3 million pixels for those of you counting at home – that offer crisp, vibrant, and clear color imagery to provide far more detail than monitors with lower resolutions:
  • A Full HD (FHD or 1080p) monitor offers 1920 x 1080 pixels
  • A High Definition (HD or 720p) maxes out at 1280 x 720 pixels

Features to look for in a 4K display

Some of the features to look for in a 4K wireless monitor for PC include:
  • Both wireless and wired connectivity
  • Optimal resolution
  • Eye comfort
  • Speakers
  • IPS technology
  • Height adjustability, VESA mounting, and cable management

Stand-out features and benefits of the HP U27 4K Wireless Monitor

UHD 4K and IPS technology

The HP U27 4K Wireless Monitor lets you experience cinematic quality and impressive visuals thanks to 4K resolution and in-plane switching (IPS) technology that offers sharp colors and clear views from nearly any angle.

Maximized screen area

This wireless computer monitor’s micro-edge display, with a striking edge-to-edge glass panel and slim design, has virtually no bezel encircling it to give you an ultra-wide, enhanced viewing area. It also enables seamless multi-monitor setups and eliminates cable clutter with only one connection to the wall.

Seamless visuals and smooth transitions

This wireless 4K monitor features AMD FreeSync™ adaptive synchronization technology when connected with a video cable. FreeSync synchronizes the monitor’s refresh rate with your graphics card (or GPU) to help eliminate glitches, input lags, stutters, and screen tearing. So you can see, and feel, the difference of responsive, fluid gameplay when you plug in the wireless monitor for gaming.

Fast response times

Measured in milliseconds (ms), a monitor’s response time specifies how quickly a pixel can display a change from one shade of gray to another or from black to white. The lower the number the better, and good monitors provide response times of 5 milliseconds (ms) or less.
The HP U27 4K Wireless Monitor features a 5 ms gray-to-gray response time so that your videos and games come to life with fewer blurs or stutters, more realistic imagery, and smoother performance.

Extreme detail

Contrast ratio measures a monitor’s contrast capabilities and luminance, which is the difference between the darkest black and the brightest white colors emitted. Higher contrast ratios translate into deeper blacks and better picture quality. This WiFi monitor screen delivers remarkable clarity with a 1,000 to 1 static contrast ratio and a 10,000,000:1 dynamic contrast ratio so you’ll enjoy deeper blacks, brighter whites, and crisper colors.

Share panoramic views

See vibrant details from practically any position with consistent, accurate color and image clarity that’s maintained across ultra-wide 178-degree horizontal and vertical viewing angles. Up to 178-degree horizontal and vertical viewing angles provide consistent, accurate, and bright images across the entire screen.

Highly accurate color

Adding to the many reasons that this is the best wireless monitor, it provides color reproduction with little effort and more than 99% sRGB color space. That’s ideal for all of your creative projects, including photos, videos, and more.

Anti-glare panel

The HP U27 4K Wireless Monitor features a non-reflective, low-gloss, anti-glare panel. This means you’ll experience less glare whether you’re working in a brightly lit area or enjoying your favorite content outside, even in the sun.

Increased eye comfort

Use the monitor’s HP Low Blue Light mode to filter blue light emission and shift colors to a warmer spectrum for more comfortable viewing, especially in the evening. Not only will your circadian rhythms stay on track, but more natural whites also put less strain on your eyes. You’ll love the height-adjustable stand, too, with tilt and swivel capabilities for increased eye comfort.

Down-firing speakers

Even your ears benefit from the HP U27 4K Wireless Monitor. It’s tuned for balanced audio when conducting or participating in video calls, watching movies, or listening to music. It has two integrated 3W speakers, so it’s ready to go right out of the box.

Ports for your accessories

Connect wirelessly via USB-A ports that work seamlessly with wireless keyboards and mouse dongles. And when you want or need to connect with wired cables through legacy ports such as HDMI or DisplayPort, you can use a USB-B cable to enable the USB-A ports.

Connect automatically

Download the HP Quick Pair App from the Windows store to connect automatically when within Bluetooth range. And you can manually connect right out of the box by pressing “Windows Key + K” on your keyboard.
