The A1 does not have the HDMI 2.1 port. This means that it cannot support 4K at 120 Hz. This means that, for instance, if you got a next gen gaming system, you wouldn’t be able to extract the advanced features of that machine. Your TV would be limiting; the C1 has those ports that allow for 4K @ 120 Hz
Sorry, there was a problem. Please try again later.Model OLED48C1PUB is a higher end OLED than model OLED48A1PUA. It has greater output power, all (4) HDMI ports are version 2.1 to support 4K@120Hz and has a faster processor. ^Daphane
