With its announcement of a display that delivers 3D holographic images , HP appears determined to stand out from the pack. It's not all Black Mirror-style tech, however, as the company will also debut a few more conventional, but still high-end displays at CES 2015.

The HP Z27s and Z24s sport 27- and 24-inch screens respectively, each running at an ultra high-definition resolution of 3,840x2,160 pixels (a.k.a. 4K). Connections include DisplayPort, DVI, HDMI, Mini DisplayPort, three MHL ports and a USB 3.0 port. The monitors will pivot, swivel, tilt and be height-adjustable.

The HP Z27q is a 5K display with a 5,120x2,880-pixel resolution. It houses an IPS panel so a wide viewing angle is expected. A luminance of 300 candelas per square meter and both picture-in-picture and picture-by-picture round out the major features.

The Z27s will be available later in January for $749, while the Z24s makes its debut in April at $549. Look for the Z27q in March for $1,299. UK and Australian pricing wasn't available at time of writing, but those prices convert to £490, £360 and £850, or AU$925, AU$680 and AU$1,600 respectively.

Some curve action

HP is also showing four new curved displays: the Z34c, Envy 34c, EliteDisplay S270c and Pavilion 27c. Each display features a contrast ratio of 3,000:1, sport wide 178-degree fields of view and include tech to reduce reflections.

The Z34c and Envy 34c have 34-inch screens and 3,440x1,440 resolutions. Each also houses dual 6-watt speakers with DTS Audio. Wall-mounting shouldn't be a problem as each is also VESA-compatible.

The 27-inch EliteDisplay S270c and Pavilion 27c 4000r each feature a lower 1,920x1,080-pixel resolution and include integrated dual 4-watt DTS speakers.

The 34c and Envy 34c will be out in April for $999 (£650 or AU$1,235 converted) each, and the EliteDisplay S270c and Pavilion 27c are available now for $399 in the US and around £300 in the UK (roughly AU$570).
