HDMI 2.1 Issues with Nvidia Cards

This AV receiver has persistent HDMI 2.1 problems when used with an Nvidia graphics card, especially with HDR10 and Dolby True HD. It does not support G-sync, cannot pass through Dolby Vision, and frequent EDID issues require constant power cycling. The graphical interface is considered better than the previous model but still poor, lacking an overlay for options and causing full-screen menus that disrupt viewing. After the latest update, it fails to return to the previous HDMI input, resulting in a black screen that needs a power cycle to recover.

Pros
  • + Improved GUI compared to previous model
Cons
  • − HDMI 2.1 issues with Nvidia cards
  • − No G-sync support
  • − Cannot pass through Dolby Vision
  • − Frequent EDID issues requiring power cycling
  • − Poor GUI with no option overlay
  • − Full-screen menus disrupt viewing
  • − Fails to return to previous HDMI input after update
  • − Requires power cycle to recover from black screen

Feature-Rich AVR with Strong Room Correction

An upgrade from an older Denon receiver that brings welcome new features. Bluetooth and Wi-Fi connectivity work well, and settings can be adjusted from a phone app. The higher-resolution on-screen display is a notable improvement. Pairs well with Arendal speakers, and the room correction delivers impressive results. The price is high, but for those who do not upgrade often, paying more upfront is considered worthwhile.

Pros
  • + Bluetooth and Wi-Fi connectivity
  • + Phone app for changing settings
  • + Higher-resolution on-screen display
  • + Works well with Arendal speakers
  • + Effective room correction
