Overview
['The Onkyo TX-NR5100 runs at 80 W per channel and includes 4 HDMI inputs and one HDMI output. Bluetooth handles wireless audio. The receiver measures 12.9 x 17.13 x 6.3 inches and weighs 8.4 lb, which is notably light for a full home theater receiver at this price and may reflect a different chassis or internal component profile than heavier competitors.', 'At 4.1 stars from 258 reviewers, the TX-NR5100 has a healthy review base for a sub-$700 receiver. Onkyo built a loyal audience over decades and buyers at this price point tend to have specific expectations around setup ease and audio quality that the 4.1 average suggests are largely met.', 'The 4-port HDMI count is functional for a core setup: TV, streaming device, game console, and Blu-ray player. If you run more devices simultaneously or do not want an external HDMI switcher, a competing model with 6 to 8 ports may suit better.']

Frequently asked questions
Does the Onkyo TX-NR5100 support Dolby Atmos or DTS:X?
The available spec data does not specify which audio formats are supported. Onkyo receivers in this price range historically support Dolby Atmos and DTS:X, but you should verify the current product listing or documentation to confirm format support before purchasing.
Is 4 HDMI ports enough for a typical home theater?
For a basic setup with a TV, one streaming device, a gaming console, and a Blu-ray player, 4 ports is sufficient. If you have more devices or swap sources frequently, you may find 4 limiting over time. Competitors in the same price range offer 6 to 8 HDMI ports.
Why does the TX-NR5100 weigh only 8.4 lb when similar receivers weigh 18 to 22 lb?
The listed weight of 8.4 lb is notably low for a full home theater receiver. This figure may reflect a different measurement point, a slim chassis design, or a data entry in the product listing. Buyers who want to confirm the build quality before purchasing should check the product page or retailer notes directly.
