What we've got here is an OLED monitor using the same Samsung QD-OLED panel tech that we've seen previously on other monitors such as the Alienware 34 AW3423DWF and Philips Evnia 34M2C8600, but wider.
The 77-inch Samsung S84D Series 4K OLED TV, which has an original price of $3,300, is currently available from Best Buy with a massive $1,700 discount that more than halves its price to just $1,600.
