Review on 🔌 Ultra HD 4K HDMI Splitter - 1x4 Output HDMI Hub, ARISEN HDMI Port to 4 HDMI Display Duplicate/Mirror, 4K@60 8-bit HDMI 2.0 HDCP 2.2 18Gbps High Resolution, Tempered Glass & Zinc Housing by Brian Delgado

How big is the difference between 4K at 30Hz and 60Hz? My first 4k TV used as a computer monitor was limited to 30Hz due to a limitation in HDMI 1.4. As long as the image was static, everything was fine. But in 2013 I'm used to everything happening instantly (it was an upgrade from a dual 30-inch Dell with a resolution of 2560 x 1600 pixels and about the same pixel size). It wasn't so at 30Hz... Note: In 1989 I bought a 15 inch 1024x768 30Hz monitor which was great/fantastic for its time... Well I was so annoyed by the slow refresh rate on the Scrolling more than 1/ 8th the whole area so I dumped it. That was another factor too, it was flat, at 50 inches a flat screen is useless. The focal length between the center and the corners varies greatly, so it's troublesome. So I bought a new graphics card and a 55-inch Samsung 6000-series curved TV that could handle HDMI 2.0 at 60Hz, so all the stubborn upgrades were gone. Last year (2018) it was time to switch again, now QLED, still Samsung and 55 inch and curved, much better. In short, forget 30Hz, IF you're used to 60Hz or better it just doesn't work with your brain... When I bought my first 4k TV/monitor there were no HDMI 2.0 products on the market, no graphics card , no TV, that's my excuse, but then I had no other choice, today it would just be stupid. real TV just showing TV shows, I don't think it would matter at all.
