Japan's Toshiba Corporation is expected to market its Satellite P55t laptop featuring the first ever 4K screen resolution on a laptop on April 22.

Media reports said the biggest consumer come-on of the Satellite P55t is the laptop's screen resolution, which stands at 3840 x 2160 with 282 pixels per inch. The P55t uses the Ultra HD version of 4K and not the 4096 x 2160 resolution available on some external monitors.

In addition to its Ultra HD resolution, the P55t has earned a Technicolor Color Certification that promises more natural-looking colors and true-to-life imagery. Toshiba has also bundled a free copy of Adobe Photoshop Lightroom 5 to take advantage of that magnificent Technicolor.

Pundits said Toshiba is the first company with a laptop featuring 4K. Other companies are widely expected to join the 4K party following a slew of 4K PC monitors announced over the past 12 months by Asus, Sharp and Dell.

4K resolution is a generic term for display devices such as laptop monitors having a horizontal resolution of 4,000 pixels.

The P55t is Toshiba's first Ultra HD laptop and is expected to retail at $1,500 for the base model. The laptop features a 15.6 inch screen. It comes with a quad-core Intel Core i7 processor; a 1TB hard drive; up to 16GB RAM and an AMD Radeon R9 M265X discrete graphics card with 2GB RAM.

Other specs include a backlit keyboard; four USB 3.0 ports; SD card slot; 802.11ac Wi-Fi; HDMI out and brand nme speakers from Harman Kardon. The laptop comes with Windows 8.1,
