When customers purchase an HDMI-enabled product — whether it’s a TV, gaming console, set-top box or streaming stick — they expect it to work straight out of the box. No configuration, no troubleshooting, no frustration. Just plug in and go. 

This level of simplicity is no longer a selling point — it’s the baseline. And any failure to meet this expectation can quickly lead to returns, complaints, and a damaged brand reputation.   

Why HDMI interoperability matters

HDMI (High-Definition Multimedia Interface) is a widely adopted standard, used in millions of consumer devices worldwide. But just because products use the same standard doesn’t mean they work well together in all scenarios. Variations in implementation, firmware, and hardware can create hidden problems that only show up when your device is in a customer’s hands — or worse, on a review site.  

Interoperability issues can show up in various ways:  

• No signal or handshake failure 

• Audio dropouts 

• Resolution or refresh rate mismatches 

• HDMI-CEC control failures 

• Inconsistent behaviour with different brands or models 

These types of problems can be hard to predict and replicate — unless your product has been tested in a controlled environment against a wide range of devices and configurations. 

What Resillion offers  

At Resillion, we provide HDMI Interoperability Testing (IOP) in a purpose-built lab, helping manufacturers and product developers identify and fix compatibility issues before release. 

Our goal is to help you reduce post-launch problems, ensure a smooth user experience, and protect your brand from negative feedback. 

Here’s how we support your product development: 

✅ Industry-leading HDMI IOP testing  

We test across a range of HDMI-enabled devices including TVs, soundbars, AV receivers, gaming consoles, projectors, and streaming boxes. This allows us to catch issues that only arise in specific brand or model combinations. 

✅ Faster time-to-market 

Early identification of HDMI problems means you spend less time troubleshooting after release. That leads to quicker certifications, smoother production, and fewer delays. 

✅ Fewer complaints and returns 

Compatibility issues can result in customer dissatisfaction, poor reviews, and increased return rates. Our testing helps you reduce these risks by ensuring your product works reliably in the real world. 

✅ Industry standards compliance 

We ensure your product meets the required HDMI Compliance Test Specifications (CTS) and works in line with industry expectations. That’s essential not just for quality, but for commercial partnerships and distribution. 

Real value beyond the lab

Our testing services don’t stop at pass/fail reports. We work with you to understand root causes and suggest practical fixes, helping your team improve design and firmware before products are shipped. 

We also help you stay up to date with evolving HDMI versions, from legacy implementations to the latest features like eARC, VRR, ALLM, and HDR standards.

Get ahead of HDMI issues — before your customers do 

Poor HDMI performance can seriously impact customer trust. Compatibility problems might seem minor during development, but once the product is in the market, the cost of fixing them — both financial and reputational — increases quickly. 

That’s why manufacturers rely on Resillion to help them test smarter and launch better.
