Six months ago I bought a B8 LG Oled. After years of waiting I was so excited to finally get an Oled as an upgrade from my Panasonic plasma. However, despite experiencing 4K HDR, every time I switch on the plasma I'm still deeply impressed. Of course the oled wipes the floor with LCD, I really can't say the same when compared to the plasma. The plasma is only 720p and yet still the contrast and motion is so impressive. When comparing the two I cannot honestly see the point of 4K unless you have a screen bigger than 70 inches. Even digital foundry recently did a feature where they admitted that a CRT from 2002 running at 1080p looks better for gaming compared to any of the more recent technology running at 4K. I think OLED HDR is great but really to my eyes the plasma at 720p still looks fantastic.
