The image transfer of the Barco ClickShare systems is excellent for presentations, images and texts. It can also handle videos, but this is not where it excels.
Installation
The ClickShare system works on the participant's side according to the Plug & Playprinciple. A proper installation is not necessary. If necessary, a file must be executed, but not installed. The transfer starts at the push of a button.
Compatibility
The Barco ClickShare system is compatible with common operating systems such as Windows and Mac. There is also an app for iOS and Android.
The Barco ClickShare system can work with an input signal up to 4K resolution. However, it outputs a maximum of 1,920 x 1,200 pixels. For higher resolutions, e.g. of a display, it is upscaled. Only the CSE-800 supports direct 4K output.
Image transfer with BenQ InstaShow
easy wireless connection from notebook to display or projector
up to 32 connected users possible
Button does not require a separate power supply
compatible with various end devices (WDC20)
depending on the model up to 4 users are possible on one screen
The wireless transmission of images, texts and presentations is very good and simple in the BenQ InstaShow. All systems also have an extra video mode, so this format can also be transmitted wirelessly very well.
Connection
Depending on the model, different interfaces are needed on your notebook. The first variant needs a USB and HDMI port for the connection. The second model only needs a USB-C port.
Compatibility
The BenQ InstaShow systems work according to the plug-and-play principle. You pair the host with the InstaShow Button, plug it into your notebook and start the desired image transfer.
The output resolutions of the BenQ InstaShow systems are in the Full HD range. However, the larger model (WDC20) scales the output resolution up to 3840 x 2160. This way, you can also transfer UHD content from your notebook to a desired output device.
Wireless HD systems are typically limited to Full HD signal. The exception is the celexon WHD30M-4K, which is capable of transmitting a 4K signal. When choosing a Wireless system, pay attention to the required resolution.
Compatibility
Wireless HD systems work without operating system and software. They can therefore be used independently of the PC system. You can also connect Blu-ray players or signage players to them.
Power supply
The receiver and transmitter of the systems must be supplied with power. There are variants that have to be supplied with mains power or USB power. Receivers that manage with the voltage of a USB port can be conveniently connected to projectors or displays with current-carrying USB interfaces.
Expert Tip:
Wireless HD systems can be used in everyday business or in home theaters. Depending on the system, they are often capable of 3D and audio transmission in addition to conventional image transmission.
Fast retrofitting of WLAN and WiFi
suitable for presentations
suitable for ad-hoc connection or network integration
acceptable image quality
limited suitability for videos
often proprietary solutions
Connection
Most projectors / displays do not have an integrated WLAN and must be retrofitted as an option. Manufacturer-specific solutions based on USB are usually available for this. Third-party solutions can often be used via HDMI (MHL).
Transmission quality
With business solutions, the transmission quality is often not as good as with consumer solutions. Therefore, it is recommended to use the wireless connection primarily for the transmission of presentations, texts and images. The transmission of video material should be avoided.
Software
To use the wireless functions, you usually need the manufacturer's software. This is usually available for Windows and Mac systems. If necessary, additional app solutions for Android and iOS are offered.
Expert Tip:
The manufacturer Epson is the leader in WLAN solutions for projectors. This applies to the setup, transmission and security of the network. The quality even allows the use in secured networks of large corporations.
