The impact of graphics card temporal dithering

Temporal dithering is an intentionally applied blurring method used by some graphics cards to increase the amount of color and shading that can be done on a system. It's a trade-off between a little distortion and much smoother looking pictures. During …

USB and Analog audio through PCoIP Zero Clients

This knowledge base article explains analog and USB audio behavior in PCoIP environments. When a USB audio device is used without the local USB audio driver enabled, the USB audio device is remotely bridged to the host. In this case, the audio stream data …

Which webcams are supported by the various PCoIP host/client configurations?

Please note that some webcam models have been found to contain different hardware within the same model (possibly identified by a hardware revision number), causing these webcams to behave differently when connected to a PCoIP Zero Client. Ensure to test …

What are the latency requirements for PCoIP?

PCoIP protocol itself is not sensitive to network latency, however network latency can impact the user experience. The network latency supported by products implementing PCoIP technology depends on the PCoIP host technology being used: PCoIP Remote …

What does the status of attached USB devices mean in the AWI?

In the Administrator Web Interface (AWI) of the PCoIP Zero Client you can review the status of any attached device ( i.e. monitors, usb ). The status of the device is as follows: Disconnected or Not Connected - no device connected to a display port. …

What are the requirements for USB 2.0 (EHCI) support on PCoIP Zero Clients?

Answer: EHCI (Enhanced Host Controller Interface) is a high-speed controller standard that is publicly documented and provides high speed USB functionality. Tera2 based PCoIP Clients support USB 2.0 (EHCI) out of the box on all firmware releases. The …

What is an acceptable level of packet loss?

Just like VoIP and video conferencing, PCoIP is a real time protocol. Once a packet is lost in transit, there typically isn't time to re transmit before the PCoIP session is impacted. Therefore, the most acceptable level of loss is 0%. Packet loss maybe …

Why PCoIP Zero Clients cannot operate at USB 2.0 speeds of 480Mbits/s?

The most common cause of slow USB data transfers is related to the network environment.USB data transfers are sensitive to the available network bandwidth, latency, and packet loss. Following are the few reasons that can cause the reduction in …

What USB CD/DVD drives should I consider using with PCoIP Zero Clients?

Teradici does not maintain a list of tested units. With the introduction of EHCI (USB 2) functionality, compatibility with currently manufactured DVD brands has improved greatly, particularly when the PCoIP Zero Client or PCoIP Remote Workstation Card …

How much latency does PCoIP technology add to the remote system?

The latency added by PCoIP technology to a remote system is related to the time to encode (compression) and decode (decompression) for the PCoIP protocol, which depends on the implementation. Total end-to-end latency is determined by OS latency and …
