A store pricing board needs a commercial-grade panel, not a consumer TV: 450 to 500 nits under store lights, a 16 hours a day duty rating, a matte anti-glare front and portrait mounting support. In portrait a 55 inch screen gives 1 inch capitals readable from 20 feet and about 25 price lines.
A lumber price board that runs every open hour is a commercial display job, and the grade of the panel decides whether it still looks sharp two years in. Three numbers drive the purchase. You need 450 to 500 nits of brightness so prices keep contrast under the ceiling lights, a duty rating of 16 hours a day so the panel is built for the schedule, and 1 inch of capital letter height so the customer at the far end of the aisle reads the price. On a 55 inch panel stood in portrait those three land together: a face about 48 inches tall, capitals that read from 20 feet, and room for about 25 price lines. The rest is parts: a portrait-rated mount, an outlet, and the player riding the ethernet drop already in the wall.
What kind of display works for a store pricing board?
A pricing board that runs every store hour needs a commercial-grade panel. A consumer TV carries a home-use warranty, a glossy front and no hours-per-day rating, and all three cost you on a board that hangs in a lit aisle all day.
A consumer TV is built for a living room. It ships with a glossy front, no published duty rating, and a warranty written for home use, which does not cover a commercial installation, so a failed panel in year two is on you. The glossy front also mirrors every ceiling fixture and window behind the reader.
A commercial-grade panel is built for the job. Its spec sheet states the brightness in nits, the duty rating in hours per day, a matte anti-glare front, and portrait mounting support. The table is the whole decision:
| Grade | Brightness | Duty rating | Front | Warranty basis | Right for |
|---|---|---|---|---|---|
| Consumer TV | 250 to 350 nits | none published | glossy | home use | a back-office screen run a few hours a day |
| Standard commercial | 450 to 500 nits | commonly 16 hours a day | matte anti-glare | commercial installation | the aisle pricing board |
| High-brightness commercial | about 700 nits | commonly 16 hours a day | matte anti-glare | commercial installation | a board facing a window wall |
The standard commercial row covers this board. Step up a row only where daylight hits the aisle face.
How bright does a store pricing screen need to be?
Choose 450 to 500 nits for a board under store lighting. A consumer TV's 250 to 350 nits washes out under the same ceiling lights and leaves prices gray on gray by mid-afternoon.
Nits measure the light the panel sends toward the reader, and the board has to out-shine the reflections on its own front. That is why the matte finish matters as much as the brightness class: it spreads each fixture's reflection into a faint haze instead of a mirror image. Set the backlight for the afternoon light level once the board is up, and walk the full method in set digital signage brightness for the room light.
Daylight is what moves the number. A board on an interior wall sits fine at the standard class; a board facing the front windows needs the high-brightness row.
How many hours a day does the display need to be rated for?
A rating of 16 hours a day covers a store board that runs about 12 hours a day, and a higher duty class buys nothing until the board runs past store hours.
Commercial spec sheets carry the duty line in hours per day; consumer TVs publish none, and their home-use warranty tells you the same thing. Backlight life is the other half of the number: commercial LED backlights are commonly rated to about 50,000 hours to half brightness. At 12 hours a day the board runs 4,380 hours a year (12 × 365), so it reaches half brightness in about 11 years (50,000 ÷ 4,380), well past the store's next refresh. Buy the standard commercial rating and put the difference toward the mount.
What size screen does a lumber price list need?
Size the board from reading distance, at 20 feet of viewing distance per inch of capital letter height for fast reading. A price list read from 20 feet needs 1 inch capitals, and the 55 inch panel in portrait delivers them with room to spare.
The basis: the FHWA planning figure is 30 feet of viewing distance per inch of capital height, and 20 feet per inch is the safer choice for a reader who is walking and glancing, which is exactly what a lumber customer is doing. Working from the safer figure:
- Text read from 10 feet needs 0.5 inch capitals.
- Text read from 20 feet needs 1 inch capitals.
- Text read from 30 feet needs 1.5 inch capitals.
Set the price in the size the farthest reader needs, keep the product line close behind it, and space the lines at 1.7 times the capital height. That spacing sets the line count, which the worked example below carries through. The same sizing exercise drives our andon board guide, which matches small status screens to the distance their readers stand at.
Should the price board be portrait or landscape?
Mount the board in portrait. That panel stood on its short edge is about 48 inches tall and 27 inches wide, which is the shape of a price list, while the landscape face is 48 inches wide and only 27 inches tall.
Before ordering, confirm two lines on the spec sheet: portrait support for wall mounting, and the VESA pattern. A panel that cannot stand on end says so in its mounting section, and finding that out after delivery costs a week. We make the same point for small HMI panels in order the portrait variant up front: settle orientation at purchase time, when the fix is a different model number.
Worked example: how many price lines fit on the portrait board?
A 55 inch UHD panel in portrait fits about 25 price lines of 1 inch capitals after a header, and each 1 inch line reads from 20 feet at the safer rule and from 30 feet at the FHWA planning figure.
The store hangs one board above the lumber racks; the farthest reader stands 20 feet down the aisle.
Face size. A 55 inch diagonal at 16:9 gives a long side of 55 × 16 ÷ √337 = 880 ÷ 18.36 = 47.9 inches (the sides are 16 and 9 parts, and 16² + 9² = 337), and a short side of 495 ÷ 18.36 = 27.0 inches. In portrait the face is 27.0 inches wide and 47.9 inches tall.
Pixels. Current panels of this size run 3840 × 2160, so the short face carries 2160 pixels across 27.0 inches: 2160 ÷ 27.0 = 80 pixels per inch. A 1 inch capital is an 80 pixel character height, easy work at this panel size.
Lines. Line spacing is 1.7 times capital height, so each 1 inch line takes 1.7 inches of face. Edge to edge: 47.9 ÷ 1.7 = 28 lines. Reserve 4 inches at the top for the store header and a bottom margin, leaving 43.9 inches: 43.9 ÷ 1.7 = 25.8, call it 25 price lines.
Reading distance. 1 inch of capital height covers 20 feet at the safer rule and 30 feet at the planning figure, so every reader in a 20 to 30 foot aisle gets the price.
What moves it. If the farthest reader is 45 feet out, the capitals grow to 1.5 inches (45 ÷ 30), each line takes 2.55 inches (1.5 × 1.7), and the count drops to 43.9 ÷ 2.55 = 17 lines. More distance means fewer lines of bigger type on the same face.
What mount, power and network parts does the board need?
Order a wall mount rated for the panel's weight in portrait on its VESA pattern, which for this size is commonly 400 × 400 mm, feed the panel from a standard outlet, and put the player on the ethernet drop that is already in the wall.
Mount. A portrait bracket puts the panel's weight onto points a landscape bracket never sees, and a pulled anchor drops it onto a customer. Match the mount's rated load to the panel's listed weight with margin, fix it to studs or blocking, and confirm the VESA pattern on your panel's spec sheet before ordering. For scale, the low-profile VESA wall bracket we sell is a fixed steel bracket rated to 30 lb for small panels, far below a 55 inch board; buy a commercial portrait-rated mount matched to this panel's weight.
Power. One standard outlet runs the panel and the player.
Network. The cloud player rides the drop already in the wall. A standard ethernet run is good for 100 m (328 feet) from the switch; a longer run needs a switch in the middle.
When is a different screen the better choice?
Keep the commercial panel for the aisle, go smaller for counters and endcaps, and go to a large LED sign only when the reader stands in the loading yard, because each job changes the size, brightness and duty the screen needs.
Counter and endcap signs are small-panel jobs, and that range is what we build: our small retail displays take their content from a card with no subscription and mount flush in millwork. Larger wall models are quoted per project; start from our display range and the configuration is confirmed on the quote.
If the sign has to read from a lot 100 feet out, that is an LED sign job, and we size one in choosing a large LED sign board for a shop floor.
The consumer TV row stays in the table for one use: a back-office or break-room screen that runs a few hours a day. In the aisles it is false economy.
What should I put in the quote request?
Put five lines in the request: the 55 inch diagonal, 3840 × 2160 resolution, 450 to 500 nits with a matte front, a 16 hours a day duty rating, and portrait mounting support on a 400 × 400 mm VESA pattern, then add the player and mount to the same order.
Write each line as a requirement the supplier must state back:
- 3840 × 2160 resolution on the stated diagonal
- 450 to 500 nits, matte anti-glare front
- duty rating 16 hours a day
- portrait wall-mount support, 400 × 400 mm VESA
- cloud player on the wired ethernet drop, subscription named
Order the mount with the panel so the pattern and load rating are checked against each other before the order goes in. If a supplier cannot state the duty rating or the portrait support in writing, that supplier is out.
Recommendation: Buy the standard commercial row from the table above, 55 inch diagonal in portrait, sized by the worked example, and purchase the portrait-rated mount and the player in the same order. Use a consumer TV only for a back-office screen that runs a few hours a day, and use the 700 nit class only for a board that faces a window wall.
Questions
Does the signage software run on the display itself or on a separate player box?
Both exist. Many commercial panels carry a signage module on the main board that runs the player subscription directly; others need an external player box connected over HDMI. The built-in module is one fewer device to mount and power. The external box is easier to swap when it fails or when you change platforms, and it lets you buy any display the box can drive. Either way the connection is the same wired ethernet drop.
Is a touchscreen worth adding to a price board?
For a lumber list read from across the aisle, no. Touch adds cost, a glossier front that fights the anti-glare case, and sensors nobody can reach at 20 feet. Touch belongs on a counter or kiosk screen where a customer stands within arm's reach to look up a product or check stock. Keep the aisle board a plain screen and spend the difference on brightness and the mount.
How do I change lumber prices during the week?
In the player's dashboard, from your desk or phone. Edit the price list once, publish it, and the board pulls the new version on its next refresh over the ethernet link. There is no USB stick to carry and no ladder to climb. Keep the price page in every playlist loop so a change is on screen on the first loop after it publishes.
