Key Features

CH42QK combines four HDMI sources into one flexible visual workspace. Standard split-screen layouts are available instantly, while software provides deeper control over the position, size, order and stacking level of every window.

Four HDMI Sources on One Display

Connect up to four HDMI computers, cameras, players or monitoring sources and display them together through one HDMI output.

Free Window Movement & Positioning

Use the software interface to drag each video window to the required position and create a custom operating, monitoring or presentation layout.

Independent Window Scaling

Resize individual windows to emphasize the most important source, create custom picture-in-picture designs or balance four information areas.

Layer Stacking & Source Ordering

Place video windows above or below one another and adjust the source order for overlay-style dashboards and flexible multi-layer compositions.

PANIO Zero-Second Switching

Switch sources without the disruptive black-screen delay commonly seen in basic HDMI selectors, improving live operation and presentation flow.

Made in Taiwan

Manufactured in Taiwan for professional AV, industrial imaging, control-room monitoring and commercial multi-source display applications.

Four-Window Software Control: Stack, Move and Scale

Build a layout around the information that matters. Instead of being limited to fixed templates, CH42QK software lets operators compose a customized four-source screen with adjustable position, size, order and overlap.

1

Select the Source Window

Choose any of the four HDMI input windows as the active object for editing.

2

Move It Anywhere

Drag the active window to the required screen position for a customized monitoring or presentation canvas.

3

Scale the Window

Increase or reduce the display area to create a main image, secondary preview or balanced four-window arrangement.

4

Set the Stacking Order

Move a window forward or backward to control which source appears on top when windows overlap.

5

Save and Recall the Scene

Store up to eight frequently used layouts through the control software. For integrated control applications, RS-232 commands expand scene preset capacity to 16.

Built-In Multiview Display Modes

Use a standard display mode immediately, then adjust the source arrangement or build a more customized layout through software.

4-Window Quad View

Monitor all four HDMI sources simultaneously.

3-Window View

Combine one larger area with two secondary sources.

2-Window Split

Side-by-side or top-and-bottom source comparison.

1 Main + 1 PIP

Keep one source dominant with a smaller preview window.

1 Main + 2 Small

Present a primary image with two supporting sources.

1 Main + 3 Small

Highlight one source while retaining three live previews.

Full-Screen View

Expand any selected input to the complete output display.

Non-Distorted Split

Support proportional display and point-to-point comparison workflows.
