Video: from what I can feel in playing some retro games (often more timing-critical than modern games), I could not feel any lag in the video. I've heard good things about Orei devices so I gave this one a shot. I had previously bought a similar device that was Amazon Basics branded, and that one suffered from both video lag (probably about 2 frames) and audio lag (felt like 0.1-0.2s from the video) on the output. (A preface that I only needed this to output to a 720p TV and an amp with stereo speakers) The frequent intermittency makes this device a waste of money which is a pity as the audio quality improvement is very nice when it does work as expected. This proves that only this device in the chain is causing the problem but I bought a new, short HDMI cable that supports all the latest standards just to eliminate the cable as a potential cause of the problem, but the problem occurs irrespective of which cable is used. I can eliminate the problem very easily by unplugging the input HDMI cable from the Orei device and plugging it directly into the TV – the problem disappears instantly, and reappears quickly when the signal is again routed through this device. Additionally, the audio extraction sometimes fails when the device begins working again – the amplifier doesn’t get sound when the device regains signal but the TV receives video – but either way it ruins the experience of sitting down with family to enjoy a movie. It is a random problem – an hour of flawless performance followed by disconnections every 10 seconds, or the other way around – but it occurs every time the device is used. The TV will not receive video and the amplifier will not receive audio for a few or even many signals. After a month and a half of use, it began (and continues) to drop the incoming signal. There is a noticeable improvement in audio coming from the amplifier. From the point of view of audio quality, this device does a good job. I was previously using my TV’s Audio Out to supply the amplifier but was not satisfied with the TV’s audio processing. I bought this device to extract HDMI audio to be sent to my old but very capable stereo amplifier.
