Just in time for the holidays and Black Friday, I managed to test several new LG, Samsung, and Sony displays for input lag. This update in particular will feature several 4K HDTVs that weren’t previously featured in our input lag database. An important note: some of Samsung’s 4K HDTVs reported very high input lag timings in my tests earlier this year. Some of these models received a firmware update that reduced input lag ratings by nearly half. One series that benefited from this update is Samsung’s 4K HU9000 series, once upgraded to the latest firmware. This firmware update drops the input lag down to 39ms.
Clicking the links below will send you to their respective product pages on Amazon. Alternatively, you can also visit our input lag database to compare these to other tested displays.
