# EDID

## Why can it not detect the correct resolution especially when connecting to Camcorder?

It might be related to the compatibility issue of HDMI and it's strongly recommended to use 1080P instead of 1080i as the output resolution. Please follow below steps:

1. Power off the encoder and plug out the HDMI cable;
2. Try to set the output resolution for your camcorder like 1920\*1080(1080P);
3. Plug in the HDMI cable and power on the encoder;
4. Check whether it can detect the correct resolution;

If it still cannot detect the correct resolution or it's only 1080i for your camcorder, please follow below steps:

* Try to upgrade the encoder with latest firmware which might help;
* Try to buy one HDMI EDID emulator like [DIGITUS 4K HDMI EDID emulator](https://www.digitus.info/de/produkte/video-und-audio/video-konverter/da-70466/) which is verified by connecting to JVC camcorder;

## What is the EDID?

 **Extended Display Identification Data** (**EDID**) is a [metadata](https://en.wikipedia.org/wiki/Metadata) format for [display devices](https://en.wikipedia.org/wiki/Display_device) to describe their capabilities to a video source (e.g. [graphics card](https://en.wikipedia.org/wiki/Graphics_card) or [set-top box](https://en.wikipedia.org/wiki/Set-top_box)). The data format is defined by a standard published by the Video Electronics Standards Association ([VESA](https://en.wikipedia.org/wiki/VESA)).
