There has been no official announcement yet, but a mention of it flashed on the screen during the presentation of new GPUs from AMD, which will support 8K resolution with high refresh rates.
The presenter of the presentation reported that the upcoming Samsung Odyssey Neo G9 will have a DisplayPort 2.1 port, AMD FreeSync support and ultra-wide proportions with 8K resolution — so the vertical number of dots will still be lower than that of “standard” 8K (this is hinted at by the note “8K : horizontal only” on the screen).
AMD has mentioned that it’s testing a 7680×2160 resolution for “ultrawide 8K gaming,” so it’s safe to assume that Samsung’s new monitor will have those specs, with a 21:9 aspect ratio. It is difficult to predict the price, but it will by no means be low – the current Odyssey Neo G9 model (which is in the illustration in the “cap” of the news) with a diagonal of 49″ and a resolution of “only” 5120×1440 costs more than $2000.
Samsung has not yet reacted to this “leak” of information – we can expect that the official announcement of the new monitor will take place at the CES exhibition in January. It is already known that at this event other monitor manufacturers – Acer, Asus, Dell and LG – are going to demonstrate their new products with DisplayPort 2.1.
