Our take on the 40" Class QD4 Series Hi-QLED FHD Smart VIDAA TV (40QD4SV, 2026)

This is a 40-inch 1080p smart TV using a Hi-QLED LCD panel with LED backlighting and a 60Hz refresh rate. It runs the VIDAA OS, which puts streaming apps on one home screen, and it supports DTS Virtual:X sound processing plus Bluetooth, Wi-Fi, Ethernet, HDMI and USB connections. It suits a bedroom, kitchen or small living room where a compact, low-cost set is enough and 4K adds little at this size. Against rivals it trades 4K resolution and high refresh rates for a quantum-dot-style color layer and a simple app system; buyers at this size mostly weigh panel brightness and smart-platform speed over resolution.
