Why pay more for branded cables like Infobit or Kramer when generic cables are much cheaper?

Standard cables use pure copper and have multiple layers of shielding to protect against signal interference, ensuring stable signals even over long distances. They also have precise impedance, reducing the risk of damage to the ports of expensive equipment such as projectors or LED screens.

What is the difference between a regular HDMI cable and an AOC (Fiber Optic) HDMI cable?

Regular (Copper) cables have distance limitations, typically no more than 7-10 meters for 4K resolution. AOC cables, on the other hand, use light to transmit signals, allowing them to be run up to 100 meters without signal degradation and without electromagnetic interference (EMI).

How can I tell if the cable I'm using actually supports 4K@60Hz resolution?

Check the bandwidth rating. Standard cables should specify support for 18Gbps (HDMI 2.0) or 48Gbps (HDMI 2.1), and should have a certification confirming the specification.

Why does the picture flicker or cut out when using a long HDMI cable?

This is often caused by voltage drop in the cable or signal attenuation. Switching to a higher quality cable or an active cable with a built-in signal amplification chip will help solve this problem.

How many multi-touch points does the touch system support, and what technology does it use?

It uses Infrared (IR) Touch technology or Optical Bonding in high-end models, supporting up to 20-40 simultaneous touch points (latency less than 8ms) and can distinguish between fingers, pens, and palms.

If installed in a large meeting room, how can the video signal be sent to an additional screen?

The screen has an HDMI Out port that supports 4K resolution. The image can be mirrored to a projector or large LED wall, and audio can be sent via the Audio Out to the room's main sound system.

Can I connect wirelessly for presentations without installing any software?

Yes, it supports standard AirPlay (iOS/Mac), Google Cast (Android/Chrome), and Miracast (Windows) protocols, as well as dedicated apps that support split-screen sharing of up to four screens simultaneously.

What precautions should be taken when installing on lightweight walls, and how much does the unit weigh?

Models 75 inches and above weigh approximately 50-60 kg. For lightweight walls, we recommend using a Heavy Duty Wall Mount with specialized steel anchors, or adding a steel frame behind the wall. If the wall is not suitable, a mobile stand with wheels is an option.

What is the resolution of the built-in camera, and how does it use AI to help with framing?

The camera has a 4K Ultra HD resolution and features Auto-Framing and Voice Tracking technology. It uses AI to detect faces and voices to automatically zoom in on the speaker and adjust the view to cover all meeting participants.

What security or user access control systems are in place?

There are USB Lock and Screen Lock features, support for creating separate user profiles, and authentication via NFC card to unlock the device, preventing unauthorized access and settings modification.

What is the fundamental difference between an LED Display (PH) and an LCD Video Wall?

An LCD Video Wall is made up of multiple flat-panel screens joined together, so there are visible bezels. An LED PH, on the other hand, is composed of small, bezel-less modules, resulting in a seamless, 100% integrated image.

How does the lighting in the room affect the choice of monitor?

LED PH monitors handle bright light much better (much brighter than LCDs), making them suitable for areas with a lot of sunlight or spotlights because they provide bright, non-fading images.

How is the viewing distance important when choosing a display?

It determines the pixel pitch (PH) of the LED. The closer the viewer is, the lower the PH value needs to be (e.g., PH 1.2, 1.5) to prevent the pixels from being visible. LCDs don't have this problem because they already have a high pixel density.

How does budget affect the decision-making process when choosing a video wall?

If you have a limited budget and want a large, high-resolution screen, an LCD Video Wall is a more cost-effective option. However, if you have a higher budget and want seamless visuals for your organization's image, an LED PH is the premium choice.

In summary, which type of screen is suitable for which type of application?

LCD Video Walls are suitable for control rooms, small meeting rooms focusing on data/text viewing, or areas with limited budgets. LED PH walls are ideal for stages, executive meeting rooms, indoor advertising billboards, and areas requiring a seamless, aesthetically pleasing display.
