LED Screen Rental in Kolkata
Durga Puja is not a season here, it is the industry: thousands of pandals commission sound, lighting and structural work on a scale no other Indian city matches in a single fortnight. Around that sit the Sector V IT belt, the legacy engineering, tea and jute houses, a government and PSU circuit, and a music and theatre audience that genuinely judges audio quality. Prime AV Solutions supplies the LED screen rental behind those events — designed on paper, proven in rehearsal and run by our own crew.

Key takeaway
LED Screen Rental for Kolkata’s biggest events
IMAG — image magnification — exists for one reason: so the person in row forty can read a face. The brief is visibility and legibility, not scenic design. Screen size comes from the furthest viewer: a usable rule is that text height on screen should be at least one fiftieth of the viewing distance for comfortable reading, which pushes side screens on a long ground to six metres wide and upward. Standard 16:9 formats are the right choice here, because content is a live camera cut and a presentation deck, both of which already live in that aspect and should never be letterboxed or stretched to fit a creative canvas.
IMAG lives or dies on sightlines, so balcony overhangs, lighting-rig positions and the shape of the seating decide where screens can hang and how many you need. In Kolkata that plays out at venues like Biswa Bangla Convention Centre, Science City, Netaji Indoor Stadium, and across Salt Lake, New Town, Park Street, Ballygunge.
Delay screens handle depth. Beyond roughly 70 to 80 metres from the stage, a main screen is too small to read regardless of how bright it is, so we place additional screens down the audience on their own structures. These need their own power, their own signal path — usually fibre or a long-haul SDI run rather than copper HDMI — and a decision about whether to delay the video to match the delayed audio at that position. For speech-led events we generally keep video aligned to the audio arriving at that spot, because lip-sync error reads as a fault far faster than absolute latency does.

- Working knowledge of West Bengal venue rules, power sanctions and permission timelines.
Local conditions
Producing LED screen rental in Kolkata
Weather & the rig
An IMAG screen has to stay readable in whatever light the sky provides, so sun path across the actual show hours and the brightness specification are decided together. The Kalbaisakhi nor'westers in April and May are the design case here: they arrive in minutes with 70–90 km/h gusts, which means outdoor truss in Kolkata is ballasted and signed off for wind loading rather than merely sheeted against rain. Humidity sits near 80% from April to October and the Hooghly keeps overnight dew heavy enough that an outdoor projection surface will fog by 4am and a lectern mic capsule picks up moisture if left uncovered. Jun–Sep monsoon, when the low-lying southern and central wards waterlog within an hour of a heavy cell; and Sep–Oct if you need any inventory at all for something other than Puja.
Power & redundancy
Delay and outdoor screen positions sit far from the main distribution, each needing its own stable feed, which usually means a satellite generator rather than a long cable run. CESC's city network is genuinely one of the better urban utilities in India, so indoor venues run on house power confidently. Puja pandals are a different exercise: temporary sanctioned connections are applied for formally through CESC or WBSEDCL well in advance, and the load per pandal is capped at what the application granted. Maidan and open-ground events are DG-fed with acoustic enclosures under WBPCB norms.
Permits & noise rules
Large outdoor screens draw attention from traffic and nearby residents, so siting, mounting and light spill typically need clearance alongside the event permission itself. Kolkata Municipal Corporation handles structures, the Kolkata Police Commissioner's office with the local police station licenses pandals and loudspeaker use, and WBPCB applies the noise rules with a 10pm to 6am silence period and a time-boxed festival relaxation. The Maidan is Army land, so an event there needs Eastern Command's NOC as a genuine step in the critical path rather than a formality. Drone operation is limited by the Dum Dum airport zone and by Fort William's restrictions over central Kolkata.
Load-in & access
Delay positions and mobile LED trucks need vehicle access deep into the audience area before the crowd arrives, which makes gate widths and ground conditions the real constraint. Larger goods vehicles are barred from central Kolkata through the day, and arrival timing is dictated by which Hooghly crossing the truck uses. The Puja constraint is unlike anything else in India: pandals in the north Kolkata lanes around Shyambazar, Kumartuli and Bagbazar are reached only by handcart for the final 200m, the bamboo structure is complete before any kit arrives, and the hang points are the structure the decorator built, so the rigging design has to be agreed with the pandal fabricator weeks earlier.
Season & booking
From Mahalaya through Lakshmi Puja and on to Kali Puja, roughly late September to early November, every scaffolder, generator, line array and lighting rig in eastern India is committed and rates reflect it. The Kolkata International Film Festival in November and the Boi Mela in late January take the auditoria, and Poila Boishakh in mid-April brings its own cluster of cultural programming. Peak demand runs Oct–Feb.
Crew & dispatch
Own Kolkata base, which is also the practical origin for Patna, Ranchi, Bhubaneswar and Guwahati work. Load-in support covers Alipore, EM Bypass and the rest of the city.
What it costs here
Outside Puja this is a value market with strong, experienced local technical labour at reasonable day rates, so a two-day conference costs appreciably less here than the same build in Mumbai or Delhi. Inside the Puja window the same inventory prices at a multiple and has to be committed months ahead, which is a conversation to have in June rather than in September.
Local expectations
A Bengali audience for live music will notice a coloured PA and say so — Rabindra Sangeet, band and classical programming here want natural tonality and a low noise floor rather than brute level, and the vocal chain is judged more closely than the lighting. Puja committees expect continuous operation across five days, which means shift rotation, a crew rest plan and spares on site rather than in the warehouse. Bengali-language compering is the default and the committee's own hierarchy governs stage access.
Specification
LED Screen Rental: technical specification
| Specification | Detail |
|---|---|
| Typical pitch | P2.6 – P3.9 indoor IMAG, P4.8 – P10 outdoor and delay positions |
| Legibility rule | On-screen text height at least 1/50th of the furthest viewing distance |
| Standard formats | 16:9 at 1920 x 1080 or 3840 x 2160 native, avoiding non-standard canvases |
| Delay screen spacing | Additional positions beyond 70 – 80 m of audience depth |
| Outdoor brightness | 5,000 nits minimum for daylight, 7,500 nits in direct sun |
| Switching | Barco E2/E3, Roland or ATEM with scaling handled once at the switcher |
| Long-haul signal | Fibre or 12G-SDI to delay positions, never long copper HDMI |
| Lip-sync handling | Video delayed to match audio arrival at each screen position |
| Mobile LED | Trailer-mounted 15 – 40 sq m daylight screens, hydraulic deploy in under two hours |
The switching layer is what distinguishes a working IMAG setup from a wall with a camera plugged in. A video switcher takes camera inputs, presentation machines, playback and remote feeds, and produces a programme cut plus separate outputs for the screens, the stage confidence monitors and any stream. Scaling is handled once, cleanly, at the switcher rather than panel-side. For outdoor daylight, screens need 5,000 nits or more, and mobile LED trucks are often the fastest way to deliver a large daylight-bright surface on a site with no rigging and a short build window.

Venues
Where we work in Kolkata
| Venue | Capacity | Production note |
|---|---|---|
| Biswa Bangla Convention Centre | Around 2,500 in the main hall plus a large grand ballroom at New Town | The city's only purpose-built modern convention venue, with generous clear height and working docks, which makes it the default whenever a design needs hung loads rather than towers. |
| Science City | Around 2,200 in the Main Auditorium with a smaller Mini Auditorium alongside | A fixed-seat theatre with house rigging positions and a fixed projection throw, so screen geometry is decided by the building and additional loads need the venue's engineering sign-off. |
| Netaji Indoor Stadium | Around 12,000 in concert configuration | Roof rigging is effectively unavailable, so the entire package is ground-supported, and the only vehicle approach runs through the congested Maidan roads under police bandobast on event days. |
| Rabindra Sadan | Around 1,000 seated | A cultural-complex auditorium with house infrastructure and a protective attitude to it, so visiting rigs work within the existing hang points and the build window is tight between programmes. |
| ITC Royal Bengal | Around 1,500 banquet across the ballroom and pre-function | Modern hotel with a usable service dock, but New Town traffic and the venue's own guest-movement rules push load-in to overnight slots. |

Risk control
What goes wrong, and how we stop it
What can go wrong
How we prevent it
- What can go wrong
IMAG video arrives before the delayed audio at a far position and lip-sync looks broken.
How we prevent itEach screen position gets its own video delay, measured against the audio arrival time at that exact spot during the build.
- What can go wrong
A long copper HDMI run to a delay screen works at build and drops out when the sun hits the cable.
How we prevent itAnything beyond about 20 m runs on fibre or 12G-SDI with a tested redundant path, and copper HDMI stays inside the rack.
- What can go wrong
The outdoor screen is unreadable by mid-afternoon because it was specified at indoor brightness.
How we prevent itDaylight positions are specified at 5,000 nits minimum, 7,500 in direct sun, and we check the sun path for the actual show hours at the survey stage.
- What can go wrong
The backup playback machine is a slide behind when the primary fails during a live cut.
How we prevent itMirrored machines are advanced together by the operator and tested with a live failover during rehearsal, not assumed to work.
Honest comparison
Is this the right choice for your event?
- One large centre screen instead of a side screen pairOur verdict
A centre screen is cheaper and simpler, and right when the content is a deck. For IMAG it fights the stage for attention and leaves the flanks with poor sightlines — side screens serve a wide audience better.
- Adding delay screens versus making the main screens biggerOur verdict
Bigger main screens help up to a point, then the limiting factor becomes angular size at distance. Past 70 to 80 metres a delay position is cheaper and far more effective than another two metres of main screen width.
- A mobile LED truck instead of a built screenOur verdict
For a short build window, a site with no rigging, or a one-day outdoor screening, the truck is faster and often cheaper all-in. Built screens win on size flexibility, positioning and on looking like part of a set.
