4K X – Capture Up to 4K144 with Ultra-Low Latency on PS5|Pro, Xbox Series X|S, Nintendo Switch 2, OBS and More, HDMI 2.1, VRR, HDR10, USB 3.2 Gen 2, for Streaming & Recording, PC|Mac|iPad

Bought this to upgrade my original 1080p version of this device. Elgato make quality hardware, and this allowed me to upgrade to full 4K on my streaming set up. I use it with OBS and it just presents as a webcam, you don't need to install any extra software. I'm also able to take an extra audio feed out of it, so when i'm streaming, I can capture the audio both in OBS and also out via Discord so that other people joining me on stream can get a live feed as well. It's a solid bit of hardware, dead easy to use, high quality and have had no compatibility issues. Only thing to be aware of is that this kind of device does NOT work with HDCP - so for example, if I want to use Netflix on my main PC, it'll make the screen go blank once Netflix tries to kick in HDCP. It's not a fault in the device, HDCP is designed specifically to block this kind of thing to prevent piracy. Annoying, as while I have intention to pirate, I'd like to still be able to watch Netflix without rewiring my set up to remove the capture device each time. This will be common issue on all capture devices however. Back on the positive, it works well with my 4K 60hz screens and other than when watching Netflix, I have it in live use all the time even when not streaming, zero latency issues getting in the way at all. I also have a switch connecting it to all my consoles as well (PS5, Xbox Series X) and no issues there either, no compatibility issues at all (make sure HDCP is disabled on the PS5!). Great bit of kit, highly recommended.

I got this primarily to record 1080p input streams from other devices on Mac. It was plug-and-play, HDMI goes into the source, USB-C into the Mac and it shows up. It only worked on the USB-C port nearest the power cable on my Mac M1 laptop, the other 2 USB-C ports didn't connect. Maybe insufficient power on the other ports. I found OBS software to be the best option for capturing. Elgato Studio and Quicktime are simpler to use but have very few options for configuring and OBS has video filters to adjust color and picture quality. Although I intended to use it for 1080p, I have it set to 4K as it gives a sharper image and it works great at 4K60. I can record 4K60 videos and they are smooth and clear. Connection speed is 5Gbps. The product is compact and lightweight, the supplied cables are high quality and look durable. The device barely gets warm even after using it for hours. One thing to note that I found out later is the 4K X has higher quality recording formats. I assumed the only difference was being able to capture 4K120 due to running at 10Gbps, which I didn't need but it also allows higher quality recording of the lower resolutions and framerates so if the best picture quality is needed, it may be worth paying the extra for the 4K X. The 4K S suited my needs perfectly, it's very reasonably priced and works great.

Easy to use, the quality you get for streaming with this is clear and no buffering. Would highly recommend

As someone who’s tested multiple capture solutions, the Elgato 4K X stands out for all the right reasons. Right out of the box, it impresses with a sleek, minimal design and plug-and-play simplicity. Setup is genuinely easy—no driver drama, no firmware fiddling. Just USB 3.2, and you’re good to go. Key strengths: Pristine 4K60 HDR10 Capture – The quality is razor-sharp with no compression artifacts. Whether you're streaming games, recording camera footage (what I mainly use it for), or creating content, this card captures detail and colour depth beautifully. VRR & Passthrough Support – Variable Refresh Rate support is a game-changer, especially if you're gaming on PS5 or Xbox Series X. No screen tearing, just buttery-smooth passthrough up to 240Hz at 1080p or 1440p. Ultra-Low Latency – You can monitor gameplay or live camera feeds in real-time without a hint of lag. Great for live streamers or hybrid work setups. Cross-platform Compatibility – Works seamlessly on both Windows and macOS, and with most popular software like OBS, Streamlabs, and even Zoom or Teams if you’re going the professional webcam route. Future-Proof – With full support for HDMI 2.1 features and high frame rates, this card is ready for both current-gen consoles and pro camera workflows. In short: the Elgato 4K X is an ideal choice for content creators, streamers, or professionals looking for reliability, top-tier capture quality, and features that won’t be outdated anytime soon.

it works! on my first review i did say that this device didnt work, but thanks to a family members help, he figured out that it was from not having a direct line from one part of it, as my computer only had USB port and my using an atapter to change the C cable end to a USB one had it not working properly, so my bad! as long as you have a C port fitted into your computer then it should work fine 👍

There are cheaper devices. Bought this on a sale as I was looking for a capture card to connect my console to my quest 3 headset. I was able to get audio to come through the headset but video was not working. I was not able to trouble shoot as I don't have a computer. It is not a plug in and play from my experience. Appears to be good quality, it's smaller than my hand.

Great piece of equipment

I bought this because I wanted to start recording and streaming again after almost a decade out, I have the original Elgato and I knew that it wasnt going to cut it in today's climate so I done some research and decided that the 4K S would fit my needs and budget. The packaging is premium like what you'd expect from Elgato, the device its self is really compact compared to the original Elgato and this was a very nice surprise for me and a bonus because it doesn't take up a lot of desk space! Setting it up was easy and it comes with instructions so if you're new or an old timer returning, you can't go wrong! The updated Elgato software is much, much better than the original and if you're unsure of what settings does what, there is an icon next to each of them explaining what they do, just hover over the question mark. Summary- great product, good value for money, easy setup, small device but packs a huge punch, highly recommend for console recording/streaming. P.S. if you want to record you and your friends audio you will need the chat link pro, but if you have the Astro A40 TR mixamp or mixamp pro, just plug a 3.5 cable in the back of the mixamp and directly in to your Elgalto, your voice might be low on your stream or recordings but this can be fine tuned in the Astro software, or you can invest in a mic to hook up to your PC which is what your stream/recording will hear and just use your headset like normal for your friends

I’ve been using the Elgato 4K S for a while now and honestly it works really well. The video quality is sharp and smooth, making it perfect for streaming and recording gameplay in high resolution. Setup was quick and easy, and it connects without issues. I also like how compact and lightweight it is, so it doesn’t take up much space on my desk. The performance has been stable with no lag or overheating during long sessions. Definitely a great capture card for content creators and gamers looking for reliable quality.

خورافي والله جوده قد جربت قطعه ثانين موحلوه احسن شي من شركة EIgato

ممتازه خذوها خذوها

works great, no issues, simple and straight to the point. photo has no correlation I'm at work

MacのM4でも問題なく使用できました。初めてのキャプチャーボードでしたが、映像はとても綺麗で、本体の性能には満足しています。本体がとてもコンパクトで、置き場所に困らないのも良かったです。 ただ、Switch 2をDiscordで共有する際の設定は少し分かりづらく、最初は手間取りました。慣れている友達に助けてもらって何とか設定できました。 価格はやや高めですが、画質や性能を考えると価格に見合った製品だと思います。
