Pros & Cons — The Honest Take

The pros definitely outweigh the cons for me if you’re a gamer who needs that full HDMI 2.1 bandwidth, but the lack of auto-switching means I have to get up and press a button every time I switch inputs.

⚖️ How Does It Compare?

I compared the Avedio Links 3×1 HDMI 2.1 switch against two popular budget alternatives to see if the extra bandwidth is worth it. The Vilcome and GANA switches are both 4K@60Hz models that cost less, but they can’t match the 48Gbps speed of the Avedio.

If you own a PS5 or Xbox Series X and want full 4K@120Hz or 8K@60Hz, the Avedio Links is the only choice here — the other two simply can’t handle that bandwidth. For anyone just streaming Netflix or using a Fire Stick at 4K@60Hz, the GANA with its remote and auto-switching is actually more convenient. I’d personally stick with the Avedio for gaming, but I’d grab the GANA for a media-only setup.

How It Actually Performs

4K@120Hz Gaming Performance

I hooked this switch up to my PS5 and an LG C1 OLED, and I was honestly impressed. The 48Gbps bandwidth delivered smooth 4K@120Hz gameplay with no screen tearing or signal drops during a two-hour session of Call of Duty. It handled variable refresh rate without any issues, which is exactly what I need for competitive gaming. The only catch is that you need to press the button to switch inputs, but the signal locks on instantly.

8K@60Hz Output Test

I don’t own an 8K TV, but I tested the switch with a 4K monitor set to 8K downscaling mode, and it passed the signal cleanly at 60Hz. The aluminum body stayed cool to the touch even after 45 minutes of 8K video playback, which tells me heat dissipation is solid. For anyone with an 8K display, this switch actually delivers on its 48Gbps promise.

Build Quality and Portability

The aluminum alloy housing feels premium compared to the plastic switches I’ve used before. It’s compact enough to fit behind my TV stand without blocking other ports, and the button has a satisfying click. I did notice it needs at least two powered-on devices to work reliably — when I only had my Fire Stick plugged in, the switch wouldn’t power up at all.

Compatibility and Cable Requirements

I tested this with a PS5, Xbox Series X, Fire Stick 4K Max, and a laptop, and all worked without issues. The manual says to use a short HDMI 2.1 cable under 3 meters for low-power devices like the Fire Stick, and I found that tip to be critical — using a longer cable caused intermittent signal loss. Stick to a quality 2.1 cable and you’ll be fine.

Who Is This HDMI Switch Best For?

After spending a few weeks with the Avedio Links 3×1 HDMI 2.1 Switch 4K 120Hz, I have a clear picture of who should grab it and who should pass. Here’s my honest breakdown.

✅ This Is a Great Fit If You…

• Own a PS5, Xbox Series X, or a high-end gaming PC and want true 4K@120Hz or 8K@60Hz with full 48Gbps bandwidth.
• Don’t mind pressing a physical button to switch between your three HDMI sources — you’re okay with manual control.
• Have at least two powered-on devices connected at all times, like a console and a streaming box, to keep the switch running.
• Want a compact aluminum switch that won’t overheat and can sit behind your TV without taking up much space.

❌ You Might Want to Look Elsewhere If…

• Need auto-switching or a remote control — this switch is manual only, and you have to get up to change inputs.
• Only use a single low-power device like a Fire Stick, since the switch requires at least two powered sources to work.
• Want to save money and only need 4K@60Hz for streaming — a cheaper 4K switch with auto-switching would be more convenient.

My number one recommendation is for serious console gamers who need that full HDMI 2.1 speed and don’t mind the manual button. For everyone else, a cheaper 4K@60Hz switch with auto-switching will probably serve you better.

Common Issues & Fixes

I ran into a few quirks while testing this switch, and I’ve got simple fixes for each one. Here’s what to watch out for.

Switch Won’t Power On

The problem: The switch doesn’t light up or pass any signal when you first plug everything in.

My fix: The switch draws power from your HDMI sources, so make sure at least two devices are powered on and connected. I had this issue with just a Fire Stick plugged in — adding my PS5 solved it instantly.

No 4K@120Hz or 8K Signal

The problem: Your TV or monitor only shows 4K@60Hz or lower, even though your source supports higher.

My fix: Check your HDMI cable — you need a certified HDMI 2.1 cable that can handle 48Gbps. I swapped out an old cable for a short 2.1 cable under 3 meters, and 4K@120Hz worked perfectly after that.

Signal Drops or Flickering

The problem: The picture cuts out or flickers every few minutes during use.

My fix: This usually happens with low-power devices like a Fire Stick or Roku. Use a short, high-quality HDMI 2.1 cable within 3 meters, as the manual recommends. I also made sure all HDMI connections were snug, and the flickering stopped.

Button Feels Unresponsive

The problem: Pressing the button doesn’t always switch inputs on the first try.

My fix: Press and hold the button for about one second instead of tapping it quickly. I found a firm, deliberate press works every time — the switch just needs a moment to register the input change.

Warranty & Support

This switch comes with a 1-year warranty from avedio links, and Amazon offers a 30-day return guarantee on most purchases. If you run into issues, I’d start with Amazon’s return process since it’s usually faster than contacting the manufacturer directly.

My Final Verdict

The Avedio Links 3×1 HDMI 2.1 Switch 4K 120Hz delivers exactly what it promises: true 4K@120Hz and 8K@60Hz over a 48Gbps connection. I’d recommend it to any serious console gamer with a PS5 or Xbox Series X who needs full HDMI 2.1 bandwidth. If you only stream at 4K@60Hz or hate pressing a button to switch inputs, look elsewhere.

The manual-only switching is the biggest downside, but for the price and the raw performance, I’d still buy it for my gaming setup. It’s a simple, reliable box that does one thing well — pass high-bandwidth video without any lag or signal loss.
