Hiring a projection mapping or LED wall vendor without checking their portfolio is like booking a band without hearing them play. Your event's visual impact—and your budget—depend entirely on who you trust with the technical execution. Here's how to evaluate vendors properly and avoid expensive mistakes.
Why Portfolio Matters More Than Company Size
A flashy website doesn't guarantee great installations. What matters is seeing actual work they've completed in environments similar to yours. A vendor who crushed a warehouse activation might struggle with outdoor festival conditions, and someone experienced in corporate events may lack the creative eye for live concerts.
Request case studies specific to your event type. If you're planning an experiential retail installation, ask for retail examples. If it's a music festival, ask for festival work. Vendors with 5–10 strong, relevant projects beat those with 50 generic ones.
Portfolio Red Flags to Watch
A solid portfolio should include before-and-after documentation, venue specifications, and client testimonials. Watch for:
- Vague or stock-photo-looking content. If the vendor can't explain what they did or shows generic images, move on.
- No mention of technical specs. Did they specify resolution, brightness levels, pixel pitch, or mapping complexity? Real portfolios include details.
- Outdated work. LED and projection technology moves fast. Projects from 2015 may not reflect current capabilities or best practices.
- Limited variety. If every project looks identical, they may be using a cookie-cutter approach rather than tailoring solutions.
Questions to Ask About Their Experience
When you contact vendors, dig deeper than "Do you have experience with LED walls?"
Ask specifically:
- What's your longest running installation? (This tells you about maintenance and reliability over time.)
- Have you worked in [your specific environment—indoor, outdoor, high-traffic, temperature-sensitive]?
- What was the most complex project you've handled? (Budget, scale, technical challenges.)
- How many technicians do you deploy for installations this size?
- What's your backup plan if equipment fails mid-event?
Their answers separate vendors who've handled real-world challenges from those still learning on your dime.
Checking References the Right Way
Don't just ask for references—ask specific questions. Contact at least two previous clients and ask:
- How closely did the final result match the initial vision?
- Did the installation stay on budget and schedule?
- Were there unexpected technical issues, and how were they handled?
- Would you hire them again?
Pay special attention to their honesty about mistakes. A vendor who admits they had a minor issue and fixed it quickly is more trustworthy than one claiming perfection.
Budget and Timeline Alignment
Projection mapping installations typically range from $10,000–$500,000+ depending on scale, complexity, and duration. LED wall rentals run $5,000–$50,000+ per day. Real vendors should be able to ballpark your project quickly based on scope.
Ask about timeline too. A full custom projection mapping setup usually needs 4–8 weeks for design, rendering, testing, and rehearsal. Last-minute rush jobs often result in lower quality or inflated costs. Reputable vendors will tell you upfront if your timeline is unrealistic.
Evaluating Technical Depth
Experience isn't just about years in business—it's about problem-solving ability. A good vendor can explain:
- How they'll handle ambient light or weather conditions at your venue
- Why they chose specific equipment (projector throw distance, brightness, lens type)
- How they'll calibrate and blend multiple projectors or LED panels
- What contingencies they've built in
If a vendor's answers are vague or overly technical without explaining the why, that's a warning sign.
Portfolio Documentation You Should Request
Ask vendors for:
- High-resolution photos and video clips of completed work
- Technical specifications (equipment used, resolution, brightness, coverage area)
- Venue floor plans showing how they solved spatial challenges
- Client contact information for direct reference calls
- Case studies covering setup, execution, and troubleshooting
This level of documentation separates serious operators from hobbyists. Platforms like Mercoly make it easier to review and compare multiple vendors' portfolios and experience side-by-side, saving you weeks of hunting.
Frequently Asked Questions
Q: How far back should a vendor's portfolio go? Focus on work from the last 3–4 years; technology evolves quickly in this space, and older projects may not reflect their current capabilities or equipment quality.
Q: Should I worry if a vendor has fewer projects listed? Not necessarily. A vendor with 8 flawlessly executed, well-documented projects is stronger than one with 50 low-quality listings. Quality and relevance matter far more than volume.
Q: What's a realistic timeline for a custom projection mapping project? Plan for 6–10 weeks from concept to execution for anything beyond a standard setup, including design, content creation, equipment sourcing, and rehearsal time.
