What Customers Say

Users are impressed by the G‑series’ ultra‑slim design and improved MLA OLED panel, which boosts peak brightness and gives HDR films real punch. They point out the accurate colours, smooth 120 Hz motion and comprehensive gaming support, and the option of wall‑mounting or using the included stand adds flexibility. Yet, the very high price and risk of burn‑in if static images are displayed for long periods make some cautious. The reflective glass highlights room lights and the speakers are adequate but don’t match the premium picture quality. Despite these quirks, it’s a stylish large-screen option that blends design and performance.
