Ignore the letters in a model code and compare four datasheet numbers: a duty rating that covers your longest day, 450 to 500 nits indoors or 2500 to 3000 nits behind glass, a commercial warranty of at least 2 years, and where the signage app runs. A 16-hour duty rating covers every location that switches screens off at close; screens that run through the night need the next class up.
Franchising turns every equipment decision into a template. Pick the wrong display line now and every new opening repeats it. The letters in a display model code will not tell you what you are buying; the datasheet will. Four numbers decide a commercial display line for a chain: the duty rating in hours a day, the brightness in nits, the warranty in years, and where your signage app runs. Size matters least: you already run 65 to 75 inches on menu walls, and that range is right for the job. For how a menu drives the screen choice in the first place, start with the digital menu boards guide. This page sets each number, works the longest-day calculation for a bakery-cafe, and ends with the decision for every case in the fleet.
The answer: standardize on one line, chosen from the datasheet
Standardize the chain on one commercial display line, and choose the line with four datasheet numbers. The model code encodes generation and feature bundles; the datasheet states what the panel is built to do.
- Duty rating, in hours a day. Indoor commercial lines are commonly rated for up to 16 hours a day, the class built for retail and hospitality hours. Screens that run through the night need the next class up.
- Brightness, in nits. 450 to 500 nits carries an indoor menu board; 2500 to 3000 nits is the class built to sit behind window glass.
- Warranty, in years. 2 years is the commercial standard; paid extensions take it to 5.
- Player platform. Where your menu app installs: the display's built-in app store, or a stick you add behind the panel.
Keep the diagonals at 65 to 75 inches for menu walls. Everything else in the decision sits in those four rows.
Match the duty rating to the longest day you run
The rating is the number of hours a day the panel is warranted to run. Set it from your own schedule. Count from switch-on before open to switch-off after close at the location with the longest trading day, and keep about 2 hours of margin under the rating.
Check one thing on every datasheet: some panels labeled for long days are built to fewer than 16 hours a day, so read the hours column and treat the label as marketing.
A screen that runs through the night, at a drive-thru or a transport hub, leaves the 16-hour class. Buy the next duty class up, from the same line family, so mounts, players and spares stay common across the fleet.
Worked example: a bakery-cafe's longest day
A bakery-cafe opens at 6:00 and closes at 19:00. The menu boards switch on at 5:30 for the morning bake and off at 19:30 after close-down.
Daily run time: 19:30 - 5:30 = 14 hours a day.
Weekly: 14 x 7 = 98 hours.
Against a 16-hour rating: 16 - 14 = 2 hours of margin every day, about 12 percent headroom (2 / 16).
The franchisor then signs an airport kiosk trading 5:30 to 22:30. Screens on for the whole trading day: 22:30 - 5:30 = 17 hours a day. That is 1 hour past the 16-hour rating, so the kiosk takes the next duty class up, in the same family.
Decision: the 16-hour class covers every cafe and bakery whose screens switch off at close. The higher class appears only where hours push past 16.
Brightness: 450 to 500 nits inside, 2500 to 3000 behind glass
A consumer TV panel manages roughly 250 to 350 nits, tuned for a dim living room. A menu wall sits under pendant, track and daylight all trading day, so spec 450 to 500 nits for indoor boards: roughly half again to double the consumer figure, and enough to hold contrast across a counter.
Behind window glass the numbers jump. Glass turns the panel into a mirror in daylight, and the high-bright commercial lines built for that job run 2500 to 3000 nits, five to six times the indoor number. The window case, with its own nits math, is in shop window display brightness: how many nits you need.
Size: keep the range, set the text height
The four numbers above pick the line; the diagonal only sets how much menu fits. Keep 65 to 75 inches and control legibility in the template. Capitals need 1 inch of height per 30 ft of viewing distance under the FHWA planning figure, or 1 inch per 20 ft where customers read while walking or ordering. A board read from 8 ft therefore needs capitals of 8 ft / 20 ft per inch = 0.4 in, which every panel in the range renders with room to spare. Choose the diagonal by item count: a 65-inch portrait panel carries a compact board, a 75-inch or a two-panel wall carries the full menu with promos. Spreading one canvas across several panels is its own layout job; we walk it in lay out one menu board canvas across four screens.
Warranty: 2 years standard, 5 with the extension
Commercial lines warrant 2 years as standard; consumer sets commonly carry 1 year. On a fleet the difference compounds: one claims process, one spare pool, and a warranty that names sign use as normal operation. Most makers sell paid extensions to 5 years. Get the per-location extension quote before the first order, because a panel swap at year 3, out of warranty, is the expensive path on a chain of stores. Register each panel when it is mounted; extensions commonly require registration.
Built-in player or an external stick
Let the signage app decide, before any hardware order. If the menu app you plan to franchise on installs from a display's built-in app store, use the built-in player: no box behind the panel, one power feed per wall, one platform to support at every location. If the app is not there, standardize on an external stick per screen. The panels stay interchangeable, and you can change software later without touching a mount.
Test the exact app on the exact panel before the fleet order. Some TV platforms gate app installs behind a store account, and a platform that fights your app becomes a chain-wide support bill.
For the deeper trade-offs, SoC vs external signage player vs mini PC compares the three ways to run a player, streaming stick or dedicated digital signage player covers the stick decision, and one signage player or one per screen for four TVs takes the multi-panel wall.
The three classes side by side
| Consumer TV | Indoor commercial line | High-bright commercial line | |
|---|---|---|---|
| Duty rating | none published for sign use | up to 16 hours a day | varies by model, check the hours column |
| Brightness | 250-350 nits typical | 450-500 nits | 2500-3000 nits |
| Base warranty | 1 year typical | 2 years | 2 years |
| Player | TV apps, often account-gated | built-in signage platform, or a stick | same platform |
| Pick it for | back office, staff room | menu walls, queue screens, promo boards | windows, sunlit entrances |
The same families also publish a duty class above 16 hours a day for screens that run through the night. Buy it from the same line as the indoor panels so mounts and spares stay common.
Recommendation: Standardize every indoor location on one commercial display line rated for up to 16 hours a day at 450 to 500 nits with a 2-year base warranty; keep menu walls at 65 to 75 inches; run the menu app on the built-in player when it is in that display's app store and on an external stick when it is not; buy the high-bright variant of the same family only for window locations and the higher duty class only for screens that run past close.
When something else is the better pick
A consumer TV earns its place where duty and brightness buy nothing: a back-office notice screen running a few hours a day, or a staff-room display. The same trade reads clearly for a consumer TV or commercial display for a waiting room sign. Late-running locations take the higher duty class. Window walls take the high-bright class. And when a location needs something other than a big wall panel, a counter-top menu board that plays from a memory card with no subscription sits in our menu board range, while wall, counter, table and hanging models through 75 inches are quoted per project under the display range.
What to ask for before the fleet order
- The datasheet page for each candidate model, with the hours-a-day rating, the nits and the warranty term printed on it
- The duty class above 16 hours a day, quoted for late-running locations
- The extended warranty quote per location, and the registration it requires
- A demo panel with your menu app installed and running, before the fleet order
- A mount rated above the panel's published weight, fixed into structure as the mount instructions require. A 75-inch panel hangs over customers' heads, so the fixing is a safety item, never a place to save.
- One location's kit first, running 30 days, then the fleet order
Decision, restated: the 16-hour indoor line for every store that switches screens off at close, the higher duty class for the few locations whose hours push past it, the high-bright variant behind glass, and the consumer sets in the back room.
Questions
What do the letters in a commercial display model code mean?
They encode the line, the panel size and usually the model year, and makers reshuffle them every generation. Two codes in one family can differ only in brightness or duty rating, so read the datasheet for the exact model and check the hours-a-day rating, the nits, the warranty term and the player platform.
Does a 16-hour duty rating cover a cafe open from 6 a.m. to 9 p.m.?
Screens that switch on half an hour before open and off half an hour after close run from 5:30 to 21:30, which is 16 hours and sits at the rating's edge. Automate the on-off schedule so panels run only trading hours, or step up one duty class for locations with early bake shifts or late close.
Can commercial display warranties be extended?
Most commercial lines sell paid extensions that take a 2-year base to 5 years. Get the per-location extension quote before the first fleet order, because a panel swap after the base term expires is the expensive case on a chain. Register each display when it is mounted; extensions commonly require registration.
Do all locations need the same screen size and orientation?
Standardize the four numbers and treat the diagonal per wall. Legibility comes from the text height in the template, sized from the farthest reader, so a 65-inch and a 75-inch panel can share one content design. Portrait suits a narrow queue wall, landscape a wide behind-counter board, and one template per orientation keeps every store on the same content.
