- Pixel Pitch vs. Viewing DNA
Don’t default to the finest pitch. Map the average viewing distance in your space, then add 20 % for social-distancing trends. A 1.9 mm wall watched from 3 m away burns budget for zero visual gain. Ask the manufacturer to demo the same content on three pitches side-by-side; the right one will be obvious without a microscope. - Touch Latency in Real-World Footfall
Factory spec sheets quote <3 ms because they test in 25 °C labs with one finger. wheel a stroller, a dog leash and two toddlers into the demo room. If the wall skips, it will skip in your lobby. Insist on a 30-minute multi-touch stress test logged on video; make acceptance conditional on that file. - Front-Serviceability & 30-Second Swap
Labour is the silent cost that kills five-year ROI. A module should slide out from the front with nothing more than a 3 mm hex key and two clips. Ask for a timed race: their technician vs. yours. If you can’t swap a module in under 60 seconds after two tries, negotiate extended labour coverage into the price. Interactive Game Room - PSU Redundancy Without Power-Down
Mean-time-between-failure is meaningless if you have to kill the wall to replace a power supply. Look for hot-swappable redundant PSUs mounted on quick rails. While you watch, have the engineer yank one supply during peak-white playback; brightness should not dip >2 % and no reboot should occur. - Calibration Drift Warranty
All walls look gorgeous on day one. Demand a written guarantee that ΔE color drift will stay <3 over five years, backed by an on-site re-calibration visit baked into the purchase price. Anything less is a deferred invoice. - Software Licensing That Scales
Some vendors charge per output, per pixel, or even per interactive “scene.” Lock down the licensing model now. Unlimited outputs and perpetual updates should be in the base price; otherwise your content team becomes a hostage negotiation every quarter. - Spare-Parts Stock Within 48 h
Interactive walls fail on Friday nights. Ask for the FedEx tracking history of the last ten emergency shipments. If any took longer than two business days, subtract 1 % of contract value for every additional day and put it in escrow until they open a regional parts hub. - Content-Template Library & API Interactive Game Room
You are buying a canvas, not a full-time coder. The manufacturer should ship ≥50 drag-and-drop templates and a RESTful API that your app team can test within 24 hours. No API documentation? Walk away—your marketing calendar will outrun their “custom dev queue” by week three. - Sustainability & End-of-Life Credit
LED walls are e-waste elephants. A responsible vendor offers a take-back credit: $X per square meter returned at end-of-life, plus a carbon-impact report for every shipment. Ask for the serial-number-level traceability of the recycled panels they accepted last year; if the list is short, so is their commitment. - Reference Install Older Than 3 Years
Everyone has shiny new case studies. Insist on visiting a site that has been running 12 h/day for ≥36 months. Interview the facility manager off-site; ask what has failed, how long the downtime lasted, and whether the rep still answers the phone. The answers will save you more than any discount.
Bonus: Escrow the Source Code
If the manufacturer is <10 years old or private, place the latest firmware and calibration software in escrow updated annually. If they ever go dark, you can still support your investment without ransom emails.
Print this list, score every candidate out of 100, and weight price at only 20 %. The cheapest bid rarely survives the first service call, but the right partner turns your LED wall into a profit center that keeps greeting customers long after the invoice is paid. Interactive Game Room
