Why Your Next TV Might Be a Projector: What You Need to Know Before You Buy

Why Your Next TV Might Be a Projector: What You Need to Know Before You Buy

In 2025, a midrange projector plus a screen can deliver a 120-inch image for about $2,000, cheaper than most 98-inch LED TVs. The Epson LS12000 uses a laser light engine with 3LCD imaging to produce a native 4K (3840×2160) picture with deep blacks and 1,500–3,000 lumens brightness. JVC’s DLA-NZ8 and NZ9 are native 4K (D-ILA) projectors famed for deep blacks, with some models offering 8K e-shift upscaling.

Complete Overview of Casio G-SHOCK: Features, Models, News, and Market Comparisons

Casio’s Kikuo Ibe formed ‘Project Team Tough’ in 1981 and pursued the ‘Triple 10’ target—10 m drop, 10-bar water resistance, and 10-year battery life—which culminated in the 1983 release of the DW-5000C G-SHOCK. In 1984 Casio aired the ‘Hockey Puck’ ad featuring the DW-5200, which boosted G-SHOCK’s tough reputation and earned the model the nickname ‘Hero’. The first analog G-SHOCK, the AW-500, was introduced in 1989, marking the transition from digital-only to analog-digital hybrid designs. The 1992 DW-6100 added a built-in thermometer to G-SHOCK watches. The Frogman line began with the DW-6300 in 1993 and became G-SHOCK’s ISO-certified 200m dive
