Quadra 40.3″
The largest native 4:3 professional monitor for museums and exhibitions
A turnkey exhibition display for museums and media art — designed to present archival video, historic film formats and media artworks exactly as intended, without distortion, cropping or forced scaling.
Modern displays distort historic formats. Quadra restores them.
Developed in collaboration with exhibition designers and museum curators.



Why 4:3 still matters
From the earliest television broadcasts in the 1930s through the early 2000s, virtually all moving-image content was produced in 4:3 or closely related classical formats. This includes over seven decades of television archives, documentary footage, early digital video, surveillance recordings and a large body of video art created between the 1960s and 1990s.
Since the consumer display market has moved entirely to 16:9 widescreen panels, institutions face a growing problem: there are virtually no professional-grade 4:3 monitors available for purchase. As a result, archival and art content is routinely shown with black bars, cropped edges or distorted geometry — none of which are acceptable in a professional exhibition context.
Quadra addresses this gap directly. It is a purpose-built 4:3 display for museum collections and video art — designed to present classical-format content exactly as it was created, without compromise, workaround or visual degradation.
For museums, archives and galleries, correct image geometry is not a feature — it is the baseline requirement for credible, faithful presentation.

Technical overview
Quadra is a 4:3 professional monitor designed as a dedicated display device — without embedded operating systems or consumer-grade ecosystems. Content can be driven from an external source (computer, media player, signage controller) via HDMI, or played directly from the built-in media player. This makes Quadra a fully self-contained exhibition system — ready to operate independently, without any additional hardware.
A professional system, not a consumer television.

About Quadra
EIDOTECH Quadra is a 4:3 professional monitor purpose-built for institutions that need accurate format presentation. At 40.3″, it is the largest native 4:3 professional display currently available on the market. As a dedicated museum display monitor, Quadra fills the gap left by discontinued CRT equipment and early 4:3 plasma displays — of which only a handful of units survive today, typically in poor condition. It is designed to serve the same role as iconic large-format 4:3 plasma monitors such as the Hantarex PD 40, Hitachi CMP307 and Pioneer PDP‑V402 — models that are no longer manufactured and increasingly difficult to maintain. Quadra serves as a modern CRT replacement display, offering a viable alternative to iconic CRT brands such as Hantarex, Barco and Selti — without the bulk, maintenance issues or limited lifespan of legacy cathode-ray and plasma technology.
Unlike bare 4:3 LCD panels available on the market — typically designed as components for arcade cabinets and requiring custom enclosures — Quadra is a complete, turnkey display system: exhibition-ready out of the box, with an industrial metal enclosure, anti-glare screen and professional-grade build quality. Whether used as a display for video art in a gallery, a display for video installation in a museum, or a 4:3 display for museum archives — Quadra delivers native 4:3 geometry at 1908×1430 resolution, ensuring that historic content is shown without black bars, cropping or aspect-ratio distortion. Developed in collaboration with exhibition designers and museum curators, it is the professional answer to a market dominated by consumer 16:9 panels.
