A swivel stand allows you to adjust the position of the display left or right, so you can position it to the desired angle.
3.height

462.3mm

360.7mm

The height represents the vertical dimension of the product. We consider a smaller height better because it assures easy maneuverability.
4.width

640.1mm

612.1mm

The width represents the horizontal dimension of the product. We consider a smaller width better because it assures easy maneuverability.
5.thickness

248.9mm

195.6mm

We consider a thinner chassis better because it makes the product more compact and portable. Thinness is a feature highlighted by many manufacturers of mobile devices, but it is essential for a wide range of products.

Display

1.response time

6ms

6ms

Response time is how long it takes for a display to change the state of pixels, in order to show new content. The less time it takes to respond, the less likely it is to blur fast-changing images.
2.resolution

2560 x 1440px

1920 x 1080px

Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.

The bigger the screen size is, the better the user experience.
4.pixel density

108ppi

81ppi

Pixel density is a measurement of a screen's resolution, expressed as the number of pixels per inch (PPI) on the screen. A higher pixel density translates into more clarity and sharpness for the images rendered on the screen, thus improving the quality of the viewing experience.
5.LCD display with 3 subpixels per pixels
Acer K2 K272HUL 27"
Dell S2715H 27"

Dell S2715H 27"
IPS (In-Plane Switching) is a technology used for LCDs. It was designed to overcome the main limitations of conventional twisted nematic TFT displays: limited viewing angles and low-quality color reproduction. PLS (Plane-to-Line Switching) is a type of IPS screen developed by Samsung, with increased brightness and lower production costs.
