Review on Portta 4PETHHA V1.4 HDMI to HDMI Audio Extractor Converter 4K - 2K with 3.5mm Stereo Analog & SPDIF by Tyrell Rike

When I first got it, it worked fine. The picture quality was still good, but the audio signal was weak and I had to use an amplifier to boost the signal. It's okay, as long as it works, I'm fine. But after a few days the device started to act. The image appears and disappears, appears and disappears. I checked several different video output devices (computers, a couple of game consoles, a DVD player) and several different displays (a monitor, a couple of TVs) and an HDMI signal booster to see if it was just a weak signal, and it tried several different HDMI cables and none of them changed the result. It was this device that failed after just 3 days of brief use. The price here can be tempting, but do your best and buy a better device.
