How can stretched bar monitor realize split-screen ?

To achieve split-screen functionality, a stretched bar monitor has certain requirements for its resolution, refresh rate, interfaces, and motherboard chipset. These requirements are as follows:

• Resolution: Generally, a resolution of at least 1200×720 is required to ensure a clear display in each area after splitting the screen. A lower resolution will result in blurry images.

• Refresh rate: To reduce screen tearing, a refresh rate of 75Hz or higher is recommended for the primary screen, with the secondary screen synchronized with the primary. For Full HD (1920x1080) resolution, a refresh rate of 144Hz or higher is generally more suitable for split-screen support.

• Interfaces: The stretched bar monitor needs to have sufficient interfaces, such as HDMI and Display Port, to connect to multiple signal sources. Common strip monitors may have one built-in HDMI port, two external HDMI ports, one DVI port, and one VGA port to accommodate multiple signal inputs.

• Motherboard Chipset: The monitor's motherboard chip must support split-screen functionality. Most high-end monitors meet this requirement. Sufficient chip performance ensures stable operation of the split-screen function, enabling features such as PBP (picture-by-picture) and PIP (picture-in-picture).

• Screen Features: Certain scenarios may require specialized screen features. For example, some stretched bar displays require touch support to enable touch-sensitive split-screen area selection and content switching. Others require the ability to create arbitrary polygonal cuts, enabling infinitely variable split-screen functionality.

stretched bar monitors  (also known as long strips or long-edge displays) have specific requirements for stable and efficient split-screen display (i.e., displaying multiple independent signal sources simultaneously).

Simply put, the core requirement is that the display must have "multi-view" functionality and sufficient hardware interfaces and internal processing power to support it.
