This mode sets the EDID of the capture device to the file defined by EDID (Internal) setting. In this mode the connected TV/Monitor capabilities are ignored. When using Elgato Game Capture 4K60 S+ for standalone SD Card recording, DO NOT connect it to a PC via USB. Only use the power supply bundled with your product. Portability is sadly out the question for now, so I would suggest looking into internal capture cards such as the AVerMedia Live Gamer 4K (review) or Elgato’s own 4K60 Pro (review coming soon) which performed far better than the 4K60 S+. Using the power of Thunderbolt 3 what the Live Gamer Bolt delivers is truly astonishing, with laptop gamers in particular now able to tap into serious quality captures. A unique capture card If your cards are not pre-formatted, you can format them using a computer or many cameras. Elgato Game Capture 4K60 S+ cannot format cards.

When using a dual-PC setup, the suggested setup is to used the EDID file that corresponds to the main gaming monitor resolution Latency is another of this card’s weak points. It’s trying to push 4K 60 FPS through a USB 3.0 connection. The result is a heavily delayed image coming to your preview window. The passthrough is lagless, so it doesn’t affect your gaming experience. This still negatively affects content creators since the gameplay will be desynced from other media sources like microphones or webcams. I didn’t do systematic testing, but it felt like an entire half second of delay. (Elgato says it’s about 250 ms) To mitigate this, you have to add render delay filters to you mic and webcam in OBS. How much delay exactly? Trial and error till it sounds about right. Yep… it’s as bad as it sounds. I do NOT recommend the Elgato 4K60 S+. Not in its current state for sure, but maybe not ever considering its unpredictability and giant price tag. Imagine taking it to a local tournament to record off-stream matches and getting home to realize half the footage was ruined. Well if you get this card, you won’t have to imagine! If the SD Card features these markings, it can record reliability at 30 MB/s (Megabyte) or 240 Mb/s (Megabit). In some cases, there may be communication issues between the TV/Monitor and the capture card, which prevents 1080p120 Hz from working correctly. If that is happening, please try the steps below:

The EDID file contains information about the type of signal the device (TV/Monitor) can accept, such as resolution, frame rate, HDR format, bit depth, audio, (Stereo, multi-channel), and much more. Looking at the hardware there are some key differences that can affect which you buy. The most obvious is that the AVerMedia Live Gamer Bolt requires Thunderbolt 3 to operate at all. If you don't have it, you can't use it, and that rules out a number of PCs, including virtually anything running on an AMD Ryzen CPU. The Elgato 4K60S+ has a couple of standout features, including its own hardware encoder and built in SD card slot. If you're someone who frequently travels or just needs to be able to capture footage without needing your PC handy, then this is absolutely the box to get. https://help.elgato.com/hc/en-us/articles/360038597431-Elgato-Game-Capture-4K60-S-Supported-Resolutions

You can adjust the bitrate and other aspects of the recording, by editing a settings.txt file that the Elgato automatically places on the SD Card.
