Re: Is motion blur directly related to strobe visibility or not?

Simply, I had an understanding that if we had a screen with a frequency of 1 kHz, we would get the same effect as on displays made on CRT technology, namely, the absence of the sampling and holding effect (it still seems to me that the shows that I watched on an old 21 inches lg looked perfectly sm...

EMF high brightness high contrast blur reductions can cause those symptoms

but since u use monitor without any tech of blur i think its related to EMF
What else is EMF, what does it mean?

Why do my eyes hurt when I sit at the monitor but do not hurt when I do it with a smartphone?

Look, I have a philips 245e1s and after at least 2-3 hours of action behind it (games, videos, working with text, etc.) my eyes start to hurt and they turn red. But I also have two smartphones: realme c2 and xiaomi redmi note 4. And when I sit behind them my eyes do not hurt at all, and when I sit d...

Re: Sony 2021 Flagship Smartphone Display

Sony has upped the bar with its latest flagship's display and camera. https://www.sony.com/electronics/smartphones/xperia-1m3 This looks like an inflection point where great motion playback and capture get more emphasis than the spatial resolution. --------- DISPLAY RESOLUTION 4K HDR OLED (3840 x 1...

Re: Why isn't the size of TVs (non-modular) growing?

Sizes have grown since the small TVs of the 1940s which were only a few inches -- usually less than 10 inches in those days! And CRT tubes never grew beyond about 40" by the 1990s. In that context, direct-view TV size growth over 30 years from 1990s to 2020s was scorching fast compared to the 50 ye...

Re: Is motion blur directly related to strobe visibility or not?

Finally, it dawned on me that if I understood correctly, a 7680x4320 display at 960 Hz will give the same level of blur as 1920 x 1080 at 240. From a pixels-of-blur, yes . From a physical-inches-of-blur, no . Confused? Here’s an explanation Hz will determine physical distance of blur on a sample-an...

Re: Is motion blur directly related to strobe visibility or not?

Listen to mark, why don't you extend the aliasing visibility test by adding the following tests there 1.Siemens star with the ability to adjust the diameter of the circle, the number of lines, the ability to make it spin clockwise or vice versa (with the ability to adjust the speed in pixels) 2.tes...

Re: Why isn't the size of TVs (non-modular) growing?

and then I thought that by 2010-2015 there would be options in sizes 100,110,120 and more What is you viewing distance? What horizontal FOV would these TV sizes give you? A take from my personal perspective... At home, I run 50" TV with viewing distance roughly 2.7 m (9 feet). This gives approximat...

My eyes hurt when I use the philips 245e1s , why ?

So earlier (from 2016 to the beginning of 2021) I had a samsung syncmaster 710n, and for some reason my eyes always hurt when working with it (I am already silent about games), then I thought it was an old monitor with ccfl backlight and technology not run-in (I met reviews on the Internet for 2005)...
