The Logic LT-IR75CX is a 75-inch interactive flat panel display designed for classrooms, offices, training centres and other professional spaces. Developed by Logic, the display brand of Online Instruments India, it combines a 4K screen with touch support, built-in cameras, microphones and wireless screen sharing.
Unlike a regular TV or monitor, the Logic LT-IR75CX is built for collaboration. It runs Android 14 and supports features such as digital whiteboarding, app access, video conferencing and screen sharing. The display carries an MRP of Rs. 3,19,000, while its current listed price is Rs. 2,19,500.
Logic LT-IR75CX: Display and Touch Experience
The Logic LT-IR75CX features a 4K UHD display with a 3,840×2,160-pixel resolution and a 60Hz refresh rate. It has a rated typical brightness of 450 nits and a 5,000:1 contrast ratio. The 178-degree viewing angles also make it easier for people sitting away from the centre to see the content clearly.
Touch interaction is the main attraction here. The panel supports up to 50 touch points and 20 simultaneous writing points, with a claimed response time of 2.5ms or less. During use, touch response felt smooth, whether I was writing on the screen, navigating menus or opening applications.
The display comes with two styluses that attach magnetically to the bottom. This is a useful addition during presentations and classroom sessions.
Android 14 and Connectivity
The Logic LT-IR75CX runs Google EDLA-certified Android 14, allowing users to download apps from the Google Play Store. The display is available with up to 16GB of RAM and 256GB storage. The reviewed model had 16GB RAM and 256GB storage, which was enough for presentations, web browsing and Android applications.
Connectivity options include Wi-Fi 6, Bluetooth 5.3, NFC, HDMI, USB 3.0, USB Type-C, DisplayPort, VGA, RJ45 and audio ports. Connecting a laptop through HDMI or USB-C was straightforward, and switching between inputs was quick.
Camera, Audio and Smart Features
A 50-megapixel AI-backed camera sits on the top bezel. It supports auto framing and speaker tracking, making it useful for video meetings. The eight-array microphone system also delivered clear voice pickup during calls.
Audio is another strong point, with two 20W speakers and a 20W subwoofer offering a total rated output of 60W.
The display also includes AI features such as Live Multilingual Subtitles, AI Smart Mapping, Smart Quiz Builder and an AI assistant. Wireless screen sharing supports up to 30 connected devices across Android, Windows, iOS and macOS.
