Pretty decent USB capture card
Reviewed in the United States on October 4, 2018
The LGX2 USB 3.1 unit does a fairly decent job doing what it does. It captures 1080p and 4K at a near-stable 60fps. (though I only use the 1080p60 setting for streaming, Twitch doesn't really recommend streaming in 4K quite yet)
My Avermedia LGX2 was tested with the GIGABYTE GTX1080 GAMING OC WINDFORCE O8G NVENC GPU encoder.
Picture quality is really good with color-enriching automatic dynamic range correction built into the USB3.1 unit. This feature will correct the range of color from standard HDMI input to remove color washout. And I must comment that it looks really, REALLY good !
The only issue I have had with the device is the video-freeze issue after about 2 hours of constant recording/streaming time. It seemed to happen repeatedly after the 2 hour mark or so. This isn't necessarily Avermedia's fault, its a problem in Windows 10 post-Fall Creators update with USB devices. I'd have to keep killing my video capture source and restarting it to work around the issue.
This was fixed by adjusting power settings for USB Selective Suspend to "Never" and installing Avermedia's very useful Beta driver to ensure Windows does not place the device into selective suspend or USB powersaving mode during my stream.
You'll know if you need to install the Beta driver if you are streaming and suddenly the Blue activity indicator on the front of the unit turns red. This means the device isn't getting its proper power requirement, and you'll need to address the issue.
Do not use a third party USB3.1 cable with this unit. Use the one provided. I tested a few other "certified" cables for the kicks, and they don't seem to work like the one in the box does.
I knocked off a star for having to fiddle with and fix the video freezing problem but otherwise:
- RECentral 4 software is great, its not terrible like Elgato's Game Capture Suite. (I came from Elgato products and must say Avermedia has been a breath of fresh air)
- Hasn't crashed once yet for me, and it worked immediately with StreamLabs OBS as a Video Capture source, no questions asked.
- Displays video as advertised, at a smooth frame-rate with rich color range (and very nice simulated HDR color range at that for devices that do not support it)
- Has really improved the quality of my stream !
Thanks Avermedia for a decent product, even with the few issues it has, they're fixable.
