Common questions before you buy

Still deciding on brand, size or budget? Start here — or send us your requirement directly.

Which brand is right for my classroom or boardroom?

It depends on room size, budget and software needs. MAXHUB and Teachmint suit everyday smart classrooms, ViewSonic, LG and Samsung work well for larger boardrooms and signage, and Epson fits budget-conscious or very large-format rooms. Tell us your requirement and we'll recommend a fit — not just push one brand.

Do you handle installation, or just supply the hardware?

Both. Our team surveys the site, mounts the display, sets up networking and configures the software before handover — it isn't left to a local electrician.

What warranty comes with the display?

All products are sourced through authorised brand channels and carry full manufacturer warranty, in addition to our own installation support.

Do you offer AMC (Annual Maintenance Contracts)?

Yes — AMC plans covering periodic servicing, spare parts and priority support are available once the standard warranty period ends.

What screen size should I choose?

As a general guide: 55″–65″ for small classrooms and huddle rooms, 75″–86″ for standard classrooms and mid-size boardrooms, and 98″ or a modular LED wall for auditoriums and large conference halls. We'll confirm the right size for your room during the site assessment.

Do you supply outside West Bengal?

Yes — we supply and coordinate installation pan-India. Get in touch with your location and requirement for a quote.
