About this deal

In TESmart's KVM switch, we add EDID emulators in each input port, so while switching the input ports, no matter the computer is current active selected or not, the computer still can always get correct EDID. This keeps the display settings of the computer would not be changed while switching. Reset HPD-event on the fly, Cable equalization, HDCP Pass-Thru, Lip Sync Pass-Thru, CEC Protocol Pass-Thru And the EDID standard is so baked-in to modern video formats that it’s kind of hard for things to go wrong. There’s not a way you can “break” the EDID process because you’d have to be messing with the pins on the transfer cables, or modifying the hardware and code on the respective devices motherboards.

I n terms of ordinary KVM switch, a s only one of the computers that connected to KVM can be selected to connect to the display, when switching the ports of the KVM, the other computers are unable to access the display ’ s EDID, then the computers change the display settings accordingly , which will cause a problem that after users set the window position, it will return to original position the next time it switches to current channel. Extron products include features to help prevent or solve many of them by properly managing EDID communications between sources and displays in AV systems. These features provide automatic and continuous EDID management with attached source devices, ensuring proper power-up and reliable output of content. The PC is able to read the EDID information, but the graphics card limits the output resolution to XGA 1024x768, a resolution most displays can accommodate, ensuring a usable image and reducing the likelihood of no image being displayed. If this does not match the native resolution of the display, fonts will likely appear to be abnormally large, small, or fuzzy.In Windows 7 and 8 if you unplug a display that will trigger a hot plug event which may reconfigure your displays. If you load the EDID onto a port that does not have a display attached make sure you select the correct port. Each physical port on the Quadro Card supports different connection types: If you have a video source that has to go to a receiver or HDMI switcher, for instance, and then to a screen, you’re adding steps that the EDID process has to make it through before things will work properly. EDID, or Extended Display Identification Data, is a metadata format used to describe their capabilities to a video source. The EDID data structure includes the manufacturer name and serial number, product type, phosphor or filter type, time of day supported by the display, etc. Detects and resolves issues associated with signal handshaking between source and destination devices

For televisions, this is probably going to be one of a small handful of options. But for monitors or other irregular screens, this helps HDMI output the right resolution even in strange edge-cases like ultrawide monitors. EDID information is typically exchanged when the video source starts up. The DDC specifications define a +5V supply connection for the source to provide power to a display's EDID circuitry so that communication can be enabled, even if the display is powered off. At startup, the video source will send a request for EDID over the DDC. The EDID/DDC specifications support hot plug detection, so that EDID information can also be exchanged whenever a display is reconnected to a video source. Hot plug detection is not supported for VGA, but is supported in digital interfaces including DVI, HDMI, and DisplayPort. For these interfaces, the display device will supply a voltage on an HPD - Hot Plug Detect pin, to signal to the video source device that it is connected. The absence of a voltage on the HPD pin indicates disconnection. The video source device monitors the voltage on the HPD pin and initiates EDID requests as it senses incoming voltage. EDID Issues If you press the copy sink button, the display’s EDID is copied and placed into the Custom EDID bank number 8 (White LED). Once it is done, HPD event is also created and completes in about 2 seconds. How do you switch between EDID Tables ? There are a total of 5 EDID Tables inside the unit (Each table includes 8 EDID banks). Please watch below video for an easy understanding on how to select the right EDID table and then the right EDID bank for your needs. Related productsEDID records the information of a display such as the dimensions/screen size, original resolution, color properties, frequency range limits, etc. EDID handshakes enable the information exchange and when the computer gets it, it will deliver the image that fits the display. LED indicators provide power and signal status information for +5 volt source supply, hot plug detect, and HDCP I f the computer is unable to get the EDID of the display , the computer can ’ t know which display device it is connected, then PC may output a very low resolution picture or even not output . KVM Extenders enable the transmission of video data over long distances, whereas KVM Switches provide connectivity between multiple sources and one set of screen and peripherals or vice versa. Both technologies act as a connection intermediary between one or multiple video sources and displays. Most of the latest digital KVM devices support EDID exchange, yet some analog VGA KVM devices may require special attention and if necessary additional help from EDID Ghost Emulators (additional information below). Provide an EDID emulator that shall provide automatic and continuous EDID management for HDMI signal sources
