Questions buyers ask

Before you request a quote

Which pixel pitch do I need?
Divide the closest viewing distance in metres by about 1.2: 2 m away → P1.9, 3 m → P2.5, 4–6 m → P3–P4, roadside → P6–P10. Use the pitch finder on the home page or send us the room and we will shortlist.
Is the price per module, per cabinet or per m²?
Each product page states the unit next to the price. The wall calculator converts it into a supply estimate for your wall size; delivery, structure, processor and installation are itemised separately in the quote.
What content can the screen show?
Anything from a laptop, media player, CCTV or TV box — video, presentations, menus and live feeds — through the video processor supplied with the wall.
How long does installation take?
Most indoor walls up to 10 m² are installed and calibrated in one to two days; outdoor boards depend on the structure and permits. We survey the site first and confirm the schedule in the quote.
What warranty do you give?
Official manufacturer warranty on panels and controllers, serviced by our own engineers in Kathmandu with spares in stock. Warranty terms are itemised in every quote.
Do you deliver and install outside Kathmandu?
Yes. We have installed in Pokhara, Butwal, Bhairahawa, Dang, Dhangadhi, Lumbini and across the valley. Delivery and travel are itemised in the quote.
