AVerMedia GC573 Live Gamer 4K – PCIe Capture Card for Streaming & Recording, 4K60 HDR, Ultra-Low Latency, VRR, 1080p240, PS5, Xbox Series X/S, PS4 Pro, OBS, Twitch, YouTube, Windows, PC

I can only speak for my personal use case, and for what I bought this for, it's perfect. I bought the 4K Live Gamer for capturing 4K footage of retro games for my youtube channel and it's handled everything I have thrown at it with almost zero lag.If your intention is to use this capture card in a similar way to me, then it will do everything you want. I originally used this with the OSSC, with the 4K Live Gamer accepting every signal I input. I have since bought a Retrotink 5x, and while researching before buying the Retrotink, I saw many not getting the 1440 signal detected by the 4KLG. I bought it anyway, as 1080p was acceptable, and I wanted the composite signal the Retrotink accepts. I was pleasantly surprised when the 4KLG accepted every signal the Retrotink x5 output. This is the same for the OSSC, I saw scaremongering of the same type about OSSC not accepting signals, but unless I received some magical version of the 4KLG, everything works great.Consoles I have tried are as follows; NES, N64, SNES, Megadrive, Mastersystem, PS1, PS2 and OG Xbox. Note though, consoles that require it, have been modded to output an RGB signal (which most stock retro consoles will not do), and I have spent £100s buying the best quality retro cables and modding my consoles which helps the signal quality. Regardless though, at the end of the day, all these consoles signals are being processed through the OSSC or Retrotink 5x, so if you are planning to use these upscalers, this is the ultimate capture card. I cannot speak for older Retrotinks or the Framemeister, but I have seen people struggling with the signal swapping delay and video output of the Framemeister as it is old tech now.Not all is positive though, I found the customer support incredibly unhelpful. I don't believe English was the first language of person I was emailing, so I will go easy. I was getting a popping sound in the audio, and support E-mail reply I got was along the lines of "these are the common fixes, if it doesn't help, we won't offer any further support". I'm paraphrasing of course, but considering the fix had nothing to do with what they offered, I have very little trust in them to offer genuine support.I'll quickly run through some technical setup tips and problem fixes that I had in case it helps someone else. First off, PCIe has become far more complicated, so you might have speed problems based on the age and spec of your PC. PCIe has individual lanes that shares bandwidth when multiple devices are used. I would suggest not buying this if you don't have at least a gen 2 PCIe board, and even then, due to the bandwidth 4K uses, you might have issues if using less than Gen 3. Assuming your 16x lane is housing your GPU, you will probably be using the x8 lane for this card. This is important, because some motherboards will only allow either a M.2 NVME drive, or use of the PCIe slot not both. My point is, it's worth seriously looking into your motherboards specs and how you have configured it before you buy this as the 4x lane will probably be too slow for capturing 4K. Since buying this I have upgraded to an ASUS ROG x670 EXTREME motherboard, which is a top end £1k board paired with a Ryzen 9 7850x3d, if you have anything like this, this card will be no problem at all no matter how you configure it.My second point is related to the problem I was having with the audio cracking. Little embarrassing but make sure you are using good quality HDMI cables and I suggest not using a cable longer than 2m max. After I bought a high quality 4K cable, I realised there was a cable in the 4K Live Gamer box, so fool on me I suppose but it did fix the issue. I can confirm that long HDMI cables will lead to an unstable signal. For me, anything over 2M would cause the picture to keep dropping out.Regardless of the poor customer service, I still give this 5 stars as it really is a fantastic card. I had an Elgato 4K card and it was a nightmare, very picky about signals and cables, making it pretty much trash for what I wanted to use it for. So, in summary, if you are looking for a card that works great with OSSC and Retrotink 5x, this is a must buy over anything Elgato offers. I haven't tested it with modern consoles like PS5 and Xbox series X, but I really can't see it having any issues as they are the modern standard of video signal.Just to be clear, I am using this with a RTX4090, but I was using it in my backup rig with a 2080 Super, and it works just as good rendering a 4K capture. I cannot speak to the compatibility with AMD or Intel GPU's.Hope this helps.

I have been looking for a capture card for a while to live stream to YouTube, this worked perfectly for what I wanted. I streamed for over 4 hours and I didn't have any problems, the metal shroud keeping the card covers seems to work well as a heat sink. Just make sure your computer has good air flow and you should be good.I used StreamLabs and never touched the AVerMedia software, so I won't be commenting on how well that performs.The "Live Gamer HD 2" is the PCIe capture card, plugged in really easy. No drivers / updates required. Literally worked right out of the box so it was just plug 'n play. The HDMI pass through worked wonders, I couldn't actually feel any input lag which was nice as you do get a bit of an input delay when passing through a capture card. Huge plus on that front.Solid 1080p 60fps image quality from the nintendo switch, I had no comments during the live stream about any problems with the image quality and I watched some of the footage back and it does appear that the card DOESN'T compress the picture quality which is a good thing. You don't lose any detail in the image but does put more stress on your hardware to process it.This leads me onto my next point, people gave this 1 star because they don't know what to do or don't know how these devices work. You DO need a high end computer to live stream a decent bitrate - high resolution image. You can't expect a lower end desktop to encode the image for a live stream without problems. The best thing you can do is drop the bitrate in your streaming software until you get a smooth image, this does mean you will be sacrificing image quality the lower the bit rate though.I have attached an image of the live stream, this was recorded at 1080 - 60 fps - 6500 bitrate and this is AFTER YouTube ran it through processing and the image quality is still fantastic.

Neat card, easy to install and both XSplit and OBS picked it up as a video source immediately. I can't compare it to the Elgato 4K but I found the initial software setup of this LG4K a little more fickle than the elgato HD60 pro.The good:Fab capture image qualityEasy to installPlayed nice with all existing capture software I hadThe -1 star things:Its all software related, the capture card itself is 5*Was a bit flaky until I applied the firmware update, this was prompted during install but failed half way through. I assume because the installer tried to access the card during update. After reboot and looking for the updater, I was able to run it again as administrator and it worked fine.The RGB lighting seems weird, the only options I can see is 3 different patterns, I don't see where to set a solid colour and so I don't understand the logic of even having it. I'm sure it will come in a software update.It's too quick to complain about "no signal", when the graphic card is changing resolutions, or indeed just initialising DirectX. They should just pause the last good frame or black screen for 2 seconds and then go "no signal". It's really annoying during streams, I have one game that does it 4 times just going from menu to main game. The Elgato HD60 Pro never does it once by comparison.These are purely software issues, they are clearly proud of their device and want it to be the most important thing. AverMedia just have to remember they are part of an ecosystem and need to think more like an end user.
