Even though this is marketed as a plug-in-play device. There is some things that need to be known before you purchase this. Since this is a premium penny at over 110 dollars. The main thing people need to understand is USB Bandwidth. If you plug this 4K Cam Link and it does not work properly. Keep trying in other USB 3.0 ports. This Cam Link at 1080p 60 frames was drawing more bandwidth than other Capture Links. So you may have to test it in multiple ports. I was on a laptop. So after you figure out your USB Bandwidth you should be good.
If you are getting some lagging or freezing. You may need to download the Elgato 4k Capture Utility Software. Once the Cam Link is plugged in open the app. Hold CTRL and select the settings icon. Put it on Isochronous mode and this should fix whatever lagging or stuttering. After I did this My Cam Link runs all day. I have used it for over 4+ hours many times.
The quality and color in OBS are much clearer than in cheaper Cam Links. A much richer brighter color that pops out. It does get warm but I have never had problems. I use mine at 1080 60p and run that all day. The 4k works as well and I have run that for a while with no problems. A chunky fellow it is yet it is lightweight. It comes with a cord for a more USB 3.0 extension. Expensive and the bandwidth knowing are the only negatives I can come up with. The bandwidth issue can be handled with a little research.
