Sharp Announces 2nd Gen 8K UHD TVs at IFA

Sharp this week introduced its second-generation 8K ultra-high def TVs at IFA in Berlin. The new televisions use the company's new panels as well as the latest processors that can upscale Full-HD and Ultra-HD 4K content to a 7680×4320 resolution.

The initial lineup of Sharp's 2nd Gen Aquos 8K UHD TVs will include models featuring sizes of 60, 70, and 80 inches. The new televisions will be based on the company's new image processor that doubles its compute throughput over the predecessor and can upscale 2K as well as 4K content to an 8K resolution with a 100/120 Hz refresh rate.

Samsung's first 8K TV goes on sale next month

Samsung is announcing its first commercial 8K TV, the Q900R, at IFA 2018 this week. The QLED panel will be available in 65-inch, 75-inch, 82-inch, and 85-inch sizes, and is capable of peak brightness of 4,000 nits. It also supports the newer HDR10+ format backed by Samsung and Amazon.

The incredibly poor detail of 4K makes my eyes bleed; it's impossible to look at. At least now we'll have some more 8K options to tide us over until we reach 64K (61440×34560).

    the viewing distance recommendations for UHD are pretty much solely based on visual acuity and 8K is twice as wide and twice as high as 4K. For VA = 1.0 the optimal viewing angle would be 58.37° for 4K and 96.33° for 8K. These values were just rounded up to 60° and 100° respectively. At those angles the horizontal retina resolution for VA = 1.0 would be 3970 pixels for 4K and 8194 for 8K. If you think about that you only have maximum visual acuity in the foveola, 8K seems quite a waste; you can only see a circle with a 69 pixel diameter with maximum accuracy at the time out of 7680x4320.

    Here's the math, for those who'd like to check. [tftcentral.co.uk] Are videophiles going to be the new audiophiles?

    But, that is math for normal humans. The visualphiles have a better understanding of what can be seen than pure physics.

    Anyway, these higher and higher resolutions may have a niche market for specialized purposes, but the general public... Well, a good seller will sell you everything you do not need. You must be more happy with a television that has larger numbers associated with it, wouldn't you?
