## Overview

It offers 14 preset EDID profiles, supports resolutions up to 4K@120Hz and 1080p@240Hz, and features bi-directional auto detection for flexible installation.

## Description

HDMI 2.1 4K EDID Emulator PRO (Model: 4K-EW2), Support SCDC and Exact EDID Copy and Emulation, HDCP Pass-Through (not Bypass or Remove), 14 Pre-Set EDID Values with 2.1 Channel Audio

## Features

- Precise Matching and Easy to Use: Equipped with a true EDID copying function, it can store the EDID of an external monitor into the emulator (external EDID), including video and audio format information. It can accurately simulate an HDMI screen and audio environment. You can use the knob to switch between 14 built-in EDID settings, allowing for quick and easy simulation of the desired resolution (internal EDID).
- To Prevent EDID Loss: The HDMI EDID Emulator supports copying and emulating EDID when connecting devices such as splitters, switchers, and extenders. Cable quality and older screens might affect the success of EDID copying. If needed, please try another proper setup.
- HDMI 2.1 & SCDC: This product is compatible with HDMI 2.1 and adheres to HDCP standards 1.4, 2.2, and 2.3. It accommodates resolutions up to 1080p@240Hz 4:4:4 and 4K@120Hz 4:2:0, but it does not support 8K resolution. The device features HDCP pass-through, which permits HDMI output devices to access the display's HDCP keys when properly connected. In the absence of HDCP, the screen will either display a blank image or revert to a lower resolution. Additionally, this model facilitates 10x and 40x frequency control for SCDC handshaking and supports hot-plugging for the display. However, it does not accommodate the FRL handshaking necessary for 8K resolution.
- Bi-Directional Design: It can automatically detect the direction of HDMI (Sink and Source auto detection), supporting both forward and reverse connections, allowing the choice to connect the EDID emulator on the computer or display side, offering more convenient installation and application options.
- Headless operation supported; no monitor connection needed; even if the display is turned off. Powered by the HDMI source device; no external power supply needed. If the monitor's EDID can't be copied, please try another monitor, good HDMI cable or use internal EDID for testing. If EDID COPY function not work, please try another monitor.

## Customer Reviews

### ⭐⭐⭐⭐⭐ It worked for me
*by P***S on September 13, 2024*

The THWT emulator pretends to be an HDMI display. It does its job but I don't like the super-bright light on it that randomly flashes. It's useful for keeping graphics acceleration turned on for computers that are remote controlled without a real monitor and for preventing windows from being rearranged when an HDMI switcher is used.Using THWT requires a small flathead screwdriver to rotate a little dial (called a rotary switch) to point an arrow at 16 settings labeled 0-9 and A-F. I tested setting 6 representing a generic 1920x1080 monitor, plugged it in to a mini PC without a display, and it correctly recognized it and changed its remote-control desktop to match the monitor resolution.On rotary 0, it copies the EDID (which includes resolution, refresh rate, and make/model) of a display it's plugged into. I connected it to my computer without a display plugged into the other side of the THWT and it appeared as a 3840x2160 Acer display while the blue light on the THWT flashed regularly. When plugged into a real display, it flashed cyan, then flashed blue again until remaining solid blue.Once unplugged from the display, it flashed blue again and I rotated the switch to point at 1 which is supposed to make it emulate the last EDID it was plugged into at setting 0. I unplugged it from the computer to power cycle it, and after plugging in to just the computer, it flashed for a bit before remaining to solid blue, turning off briefly every few seconds. As expected, my computer thinks the copied monitor is still plugged in even though it's not.Unfortunately, after I turned off my main DisplayPort monitor, Windows shifted everything to another HDMI monitor that was turned off. This doesn't normally happen, and it continued to happen even after I removed the THWT and plugged in the monitor it had been emulating. I think the issue is that connecting the THWT as a 3840x2160 display made Windows clear its memory of how I use my monitors. I've had this happen before with other new monitors and it takes a few days to learn that I don't want things to shift to other monitors when I turn one of the two main ones off. Whatever reasoning Windows uses to learn new behavior is not clearly documented but has been reported by other users. It remains broken after two days and a reboot so it's very frustrating.The light on the THWT is ridiculously bright and will definitely bother people at night as it randomly flashes. I suppose it's intended to be visible behind a TV from all angles but it might need to be taped over in a bedroom setting.THWT has been around since 1990 and I verified their web site has been up since at least 2000 so I have a reasonable hope this emulator will last. Five stars.

### ⭐⭐⭐⭐ Works as intended
*by M***N on January 29, 2025*

I am using this with a KVM switch between a Mac Studio and a desktop PC using multiple monitors. Before adding this, my monitors would rearrange themselves every time I would make the switch. This successfully fixed that issue, so I'm very pleased. There is only a second or two pause after switching.I took a star off for the cost, especially since you can get KVM switches with EDID built in. At the time of this review, it costs $90 with a 5% coupon.4 out of 5 stars.

### ⭐⭐⭐⭐⭐ Useful for docks and KVMs
*by P***C on December 21, 2024*

I use this to keep my monitors from resetting whenever one turns off from the source. Works well and emulates the EDID (either included option or cloned ones) as expected
