The EVGA XR1 supports HDR pass through (not capture) while in APT mode only. We understand there may have been some confusion on this feature so we are updating the product pages to better clarify this. To enable HDR mode you first need to set the EVGA XR1 to APT mode. If there are any questions on this please feel free to contact us directly.
 
To enable APT mode, press and hold the control dial for 3 seconds until the LED's turn white:

Hey-o, If you're using the passthrough option for higher refresh rates it cuts off the OBS preview window, PS4 only supports up to 60FPS if im not mistaken, so there isn't a need to use the passthrough option unless you're using a high refresh rate camera or a gaming pc. However if you're having trouble capturing the ps4 in general without even enabling the passthrough options, you may want to consider reaching out to our support team for in depth troubleshooting if that's the case. 
You can usually contact our phone support 5 days a week from 9AM to 6PM PST @ 1 (714) 528-4500 or you can always reach out via our support email @ Support@EVGA.COM to get support 7 days a week.
