Lenovo’s ThinkVision S28u-10: A 4K Business Display
by Anton Shilov on September 5, 2019 3:00 PM EST
Lenovo has introduced its new business and prosumer-oriented display that brings together an ultra-high-definition resolution, an accurate color reproduction as well as reduced emission of blue light to improve eye comfort.
The Lenovo ThinkVision S28u-10 monitor is based on a 28-inch IPS panel of 3840x2160 resolution that can display 1.07 billion of colors and reproduce 99% of the sRGB color space as well as 90% of the DCI-P3 color gamut. For some reason, Lenovo says nothing about support of the Adobe RGB color space, which is often required by designers and photographers. Since we are dealing with an IPS display, it is reasonable to expect it to feature all known IPS peculiarities.
As is standard with Lenovo's monitors designed for business and prosumer market segments, the ThinkVision S28u-10 comes in a chassis that can adjust its tilt, but for those who need additional flexibility it has VESA mounts. As for connectivity, the LCD has a DisplayPort and an HDMI input.
One of the key selling points of the ThinkVision S28u-10 display is TÜV Rhineland’s Eye Comfort certification, which, as the name suggests, is designed to ensure that the monitor is good for prolonged use. The certificate requires a display to reduce blue light content, flicker, and reflection as well as provide consistent image quality from different viewing angles. Specialists from TÜV Rhineland test displays in accordance with safety and health requirements set in Europe, US, UK, and Hong Kong.

I am intrigued how you combine reasonable brightness, very high colour fidelity, and limited blue light emission ... careful choice of the phosphors used with the LED backlight to avoid having too much content left of 400nm?Santoval - Thursday, September 5, 2019 - link
Limiting blue light emission also affects color temperature, right? I mean my guess is that they lower the white point from the standard D65 (6,504 Kelvin) to D55 or, who knows, maybe even D50? However that would significantly affect color fidelity, so I would guess that the lowest (and thus "warmest") possible white point must be no less than ~6000 Kelvin.crimsonson - Thursday, September 5, 2019 - link
It's probably the same mode as "night mode" with smartphones. Your eyes will naturally adjust to it.Devo2007 - Thursday, September 5, 2019 - link
They'll adjust, but color accuracy definitely goes out the window with night mode on phonesDanNeely - Thursday, September 5, 2019 - link
My guess would be it has a correct colors mode with normal amounts of blue light, and a low blue mode with screwed up colors.AdditionalPylons - Friday, September 6, 2019 - link
My thought as well. At least from my understanding it should not be physically possible to produce correct colors with reduced blue light.DanNeely - Friday, September 6, 2019 - link
I suppose you could split the difference and have full gamut in the red/green color space, and then heavily compress the bluer part only; but that sounds like the worst of both worlds to me.Small Bison - Thursday, September 5, 2019 - link
The TÜV Rhineland website uses the language "adjustable blue light" instead of "reduced emission of blue light". I imagine Anton was trying to get the sentence to flow better, and inadvertently changed the meaning by doing so.PeachNCream - Thursday, September 5, 2019 - link
Marketing photo failures galore with all the beards and tattoos. IBM wouldn't have made that kind of mistake in marketing to professionals.Justwow - Thursday, September 5, 2019 - link
Have you been to a company in the 21st century? People with beards and tattoos are quite commonplace. People even wear t-shirts at work(!).
