Which screen should you use?
Any TV or monitor with an HDMI port works with the SLX Smart Box. Here's how to pick one that looks great and lasts — based on your space and how long it runs each day.
Match size to viewing distance
The further people stand, the bigger the screen needs to be.
| Viewing distance | Screen size | Typical spaces |
|---|---|---|
| Up to 3 m (≈10 ft) | 32"–43" | Counters, small rooms |
| 3–6 m (≈10–20 ft) | 43"–55" | Waiting rooms, cafés |
| 6–9 m (≈20–30 ft) | 55"–65" | Lobbies, open floors |
| 9 m+ (≈30 ft+) | 65"+ or a video wall | Large halls, atriums |
Rule of thumb: your screen's diagonal in inches should be roughly the viewing distance in feet ÷ 4. A 55" screen reads comfortably from about 6 m.
How long will it run each day?
This matters more than any other spec.
A few hours a day
A good consumer TV is perfectly fine — for example a screen that's only on during opening hours.
8+ hours, or all day
Use a commercial (also called professional) panel rated for 16/7 or 24/7 operation. Consumer TVs aren't built for continuous use — they can show image retention over time, and their warranties often exclude commercial use.
When buying, look for a stated duty cycle (16/7 or 24/7) and a commercial warranty.
Brightness for the light in the room
Brightness is measured in nits. More light means you need more nits.
| Lighting | Example | Aim for |
|---|---|---|
| Shaded indoors | Waiting room, café interior | 250–350 nits |
| Bright indoors | Near large windows, glass fronts | 500–700 nits |
| Facing daylight | Storefront window facing the street | 1500–2500+ nits |
By where it goes
A quick starting point for common spaces.
Café & restaurant counter
32"–43"
Close-up viewing. A good consumer TV is fine if it runs only during opening hours; go commercial if it's on all day.
Clinic & waiting room
43"–55"
On for the whole day, viewed from seats a few metres back. Use a commercial panel and a calm, readable layout.
Lobby & reception
55"–65"
Seen from across the room and from a distance. Larger commercial display, usually landscape.
Retail window
43"–55", high-bright
Competing with daylight. Use a high-brightness commercial or window display, often mounted portrait.
Gym & studio
43"–55"
Runs long hours in bright rooms. Commercial panel, mounted high and out of the way.
Coworking & community
55"+
A shared board people gather around. Larger screen, commercial-grade for continuous use.
What every screen needs
An HDMI input
The Smart Box connects over HDMI. Almost every TV and monitor has one.
Power nearby
A power socket within reach of the screen and the Smart Box.
Wi-Fi in range
For content updates. Wired Ethernet works too where available.
A mount or stand
Wall mount, floor stand, or a shelf — landscape or portrait, both supported.
