Our Verdict

LG C9 OLED

Sony Z9F

The Sony Z9F and LG C9 use different panel technologies, each with their advantages and disadvantages. The Z9F uses a VA panel and is much brighter than the C9, and the brightness doesn't change as much with different content (ABL). The C9 looks much better in a dark room, as the OLED panel delivers near-perfect black uniformity and an infinite contrast ratio. The C9 has a nearly instantaneous response time, but this results in more noticeable stutter when watching movies. The C9 also has a chance of permanent burn-in when exposed to static content, but the Z9F is immune to burn-in.
