yes it’s true about the crt and the remanence of the phosphor, but the crt has the difference of the lcd is that it doesn’t have a delay of response time to display the new image, you have the clarity of motion movement that no lcd can compete, so between images the crt refreshes 60 times per second, I play every day on my consumer sony crt for retrogaming, and I play on a 4k oled tv panasonic ez950. … precisely so that with the bfi I get closer to my crt in clarity, and yes indeed if you activate a shader effect of phosphorus remanence this is almost realistic, but on lcd it’s just a blurred mess, and I agree with nesguy it’s blurred … as you can see the white streak is really minimal, and far from what the shaders think they saw 20 years ago in their memory, and that is the problem… is that memories are not exactly reality.
at 3min in this video you will see a black background and a white ball, but the bloom of the white is not on my crt, it is the exposure of the camera which films… the white bars are clear in real, and the white does not overflow like haliation,afterglow.
then I test the scrolling with sonic, no blur of remanence on the palm trees in the foreground nor the mountains in the background, it is clear, no remanence, no blur… but I look at the video on my crt vga mitsubishi diamond pro 920, then you… I don’t know with which type of screen you look at … if it is a lcd ips, va etc… it is useless, it will be blurred.
what i mean about the bloom afterglow haliation is this, you can see here that it’s not the crt, but my camera and the exposure, it’s sharp and it doesn’t overflow.
here is my small contribution if it can help and you can see my mitsubishi diamondtron pro 920 vga crt that i use every day for internet forum video etc…behind the tv sony crt… I’ve done the housework since then, right?..
