I've been streaming PS5 games at 4K and this card handles it flawlessly. The 4K144 pass-through is a game changer for games like Call of Duty where high refresh rates matter. Zero lag, amazing quality.
I was worried about VRR compatibility but this card passes it through perfectly. My monitor still gets the full VRR range. Setup was easy with the software. Highly recommend.
This is the best capture card I've ever used. The video quality is crystal clear and the 1080p240 capture is perfect for slow motion analysis. The USB 3.2 speed is fast enough for 4K60. Absolutely worth the price.
The hardware is excellent. The picture is sharp and the pass-through is seamless. But the Elgato software can be a bit slow to start and sometimes glitchy. I use OBS anyway, so it's fine. Overall, good buy.
I record 4K game footage for my YouTube channel and this card lets me play at 144Hz while recording. It used to be impossible without a second PC. Now it's like nothing even changed. Highly recommend.
The card worked for a week, then my PC stopped recognizing it. I tried different cables, ports, and reinstalling drivers, nothing helped. I'm returning it. Disappointed.
No complaints.
The capture quality is superb and the VRR support is great. But the included USB-C cable is only about 1 meter long, which is too short for my desk setup. I had to buy a longer cable. Everything else is excellent.
I use this to stream my Switch and it works perfectly with the 4K pass-through. The video looks crisp and the audio sync is perfect. Easy setup. Very happy.
With HDMI 2.1, this card is ready for the new consoles and GPU's. The 1080p240 capture is a great feature for slow-mo. I can't think of any other card that offers this at this price point. Excellent.
The capture quality is stunning and the latency is non-existent. I just wish the passthrough supported 4K120 on my PS5 without needing to enable VRR. It works, but you have to set it up correctly. Slight learning curve.
It took me a while to get it to work properly. The software has a bug where the preview sometimes stays black. A restart fixed it. Once it works, it's excellent. But I was hoping for a smoother experience.
