You can browse a wide selection of 100 ft HDMI cables on Walmart.com in TV Cables & Connectors. To narrow it down, try these steps:

1. Filter by length: Select 100 ft to see long-run options.
2. Choose the spec you need: Look for HDMI 2.0 (4K@60Hz, 18Gbps) or HDMI 2.1 (8K/4K@120Hz, 48Gbps).
3. Check the cable type: Options include active copper (with boosters) and active optical (fiber) for longer distances.
4. Review install ratings: For in-wall runs, look for CL2/CL3 or plenum (CMP) ratings.
5. Confirm features: eARC, HDR, and HDCP 2.2/2.3 if your devices need them.

You can ship to home or look for pickup options when available. Product pages list specs and compatibility details to help you compare.

It can, but performance depends on the cable design and your gear. For 4K@60Hz, many customers use:

• Active copper cables: Include a built-in signal booster to help at long distances.
• Active optical (fiber) cables: Convert the signal for reliable long runs with lower interference.

Look for HDMI 2.0 (18Gbps) for 4K@60Hz or HDMI 2.1 (48Gbps) if you want headroom for 4K@120Hz or 8K. Confirm HDCP 2.2/2.3 for streaming and eARC if you’re sending high-quality audio. Keep adapters and couplers to a minimum, avoid sharp bends, and test your setup. Results can vary by devices and settings.

With HDMI, the signal is digital, so picture quality typically won’t look “better” once the required spec is met. Higher prices usually reflect:

• Long-run capability: Active electronics or fiber optics that help at 100 ft.
• Build and certification: Rated bandwidth (18Gbps or 48Gbps), HDR, and compliance like HDCP 2.2/2.3.
• Installation rating: In-wall (CL2/CL3) or plenum (CMP) for code-friendly installs.

For 100 ft runs, investing in active or fiber optic designs can improve reliability, but it doesn’t guarantee a visible quality upgrade. Match the cable to your resolution, refresh rate, and install needs. Reviewing specs and the return window on the product page can help you buy with confidence.

Pick based on your setup and install plan:

• Resolution/refresh: 4K@60Hz needs HDMI 2.0 (18Gbps). For 4K@120Hz or 8K, choose HDMI 2.1 (48Gbps).
• Cable type: Active copper (with booster) or active optical (fiber) for long runs and reduced interference.
• Install rating: In-wall? Look for CL2/CL3. Some spaces may require plenum (CMP).
• Directionality: Fiber and some active cables are one-way—connect “Source” to your device and “Display” to the TV/projector.
• Features: eARC, HDR, and HDCP 2.2/2.3 for modern AV setups.

Measure your route carefully, add a little slack, and confirm specs on the product page before you buy.

It can be, provided the cable is rated and installed appropriately. Consider the following:

• Use rated cable: Look for CL2/CL3 for in-wall, or CMP (plenum) if your local code requires it.
• Plan the path: Avoid tight bends, use low-voltage brackets, and consider conduit for future upgrades.
• Check directionality: Active optical cables often have “Source/Display” ends—verify before pulling.
• Keep separation: Don’t run parallel and tight to AC power lines to reduce interference.
• Test first: Verify signal at full resolution before and after the pull.

Local codes can vary, so consulting a qualified installer may be helpful for complex runs.
