5K resolution

While Samsung lists the UN105S9W as a 4K UHD TV, it actually has native resolution of 5120 × 2160 (a 64∶27 or ≈21∶9 aspect ratio) which classifies it as a 5K display due to the horizontal pixel count of ≈5,000.

[5] Jupiter Systems in California was first to launch a full line of 5K resolution 21:9 large LCDs named Pana for the enterprise market in 2020, with engineering development that traced back to 2018.

[14] NVIDIA introduced HBR2 support on their products with the Kepler family of GPUs, starting with the GeForce GTX 680 in March 2012.

HDMI gained similar capability in version 2.0, which increased the maximum allowed transmission speed to 600 MHz TMDS (18 Gbit/s).

The NVIDIA GeForce GTX 980, launched in late 2014, was the first graphics card to implement this capability, which was sufficient for 5120 × 2880 at 30 Hz with 30 bit/px color depth.

[16] Although 5K 60 Hz over a single cable was only made possible in 2016 with the launch of the GeForce 1000 series and Radeon RX 400 series, monitors which predate version 1.3 of the DisplayPort standard such as the Dell UltraSharp UP2715K offer the ability to run at 5K 60 Hz by using two HBR2 DisplayPort connections concurrently in a specialized picture-by-picture mode.

[18] Only the highest standard frequencies (24 / 30 / 50 / 60 / 75 / 85 / 100 / 120 / 144 / 200 / 240) are listed.CVT-RB timing format and uncompressed RGB or YCBCR 4:4:4 color mode are assumed.
