What is Quad HD?
Quad HD stands for “Wide Quad High Definition”. WQHD is another name. Expresses the number of compressed pixels. Movies and pictures appear more clearly if the pixel rate on the screen is high.
The Quad HD screen has a resolution of 2,560×1,440 pixels. This is four times the number of pixels you get in a standard HD panel (720p). But quad HD displays are 4K Ultra HD. WQHD screens also have a 16: 9 widescreen aspect ratio, which explains where the ‘W’ value in WQHD comes from.
What is 4K or UHD?
