    Ironic, gallons per mile is actually a more useful measure for high fuel efficiency vehicles because it directly represents fuel consumption. Differences in MPG are more misleading to intuition as MPG increases.

    For example, upgrading from an 18mpg car to a 28mpg car (Option A) saves more fuel than upgrading from a 34mpg car to a 50mpg car (Option B). It is easy to be misled that Option B would result in more savings because it is an upgrade of 16mpg rather than only 10mpg in Option A.

    GPM does not have this problem and the differences can be compared directly, Option A in GPM is 5.5gpm -> 3.5gpm, for a difference of 2gpm while Option B is 2.9gpm -> 2gpm for a difference of only 0.9gpm, making it easy to see that the Option A is a greater impact to fuel economy than Option B.




  • Well this is getting silly if you’re just going to keep repeating objectively wrong things and also misrepresent what I’ve said (‘anything your current hardware can’t do is a “marketing gimmick”’ 🙄🙄🙄)

    Since we’ve left good faith diacussion and entered the realm of silly, fine! You’ve activated my trap card! Can your OLED do this??? presses degauss button You can see 85 Hz flicker, but I can bench press 1200 lbs and run a 60 second mile 🤪

    Enjoy your OLED and I’m glad you’re finally getting to enjoy perfect color, true blacks, and high contrast again after all these years!


  • You might want to reread my comment because you’re just making false claims that are already addressed about color and resolution (my CRT can display 2560x1920), or you’re only acknowledging low quality CRTs. I’ll give you 4K resolution as a flat panel win over tubes, and obviously size and aspect ratio, but I personally don’t see any value in it, as 4K resolution, ultra-wide aspect ratio, and extremely high framerates are simply marketing gimmicks. Obviously, others do see value in these and that’s fine.

    Perceiving flicker at 85Hz rate is literally far beyond human capability. 72Hz is an ultimate upper limit on where any flicker is perceptible to a human… and I run my monitor at 120Hz for competitive games lol. It is not physically possible that a human could see flicker at 85Hz. Backlight strobing of an LCD is not related to refresh rate, so would likely by 60Hz matching AC wall power.

    Anyway, there are some reasons that OLED is better, just unrelated to display quality. You can probably fit more on your desk than just a keyboard and don’t risk your back when moving your monitor.


  • Yeah that’s still normal. Unless we’re both just special. When looking at the center of a 60Hz CRT, the flickering is seen around the edges of the screen where I am not focusing. Or the whole screen if I look to the side of it. I also perceive LEDs flickering the same way you describe.

    I’d guess the fact that we are not seeing it in our focus vision probably has less to do with physical attributes of the eye and more to do with the way our brains create our perception of vision. There’s a lot going on there. Like our eyes are also constantly rapidly moving, and we are not conscious of or perceive that movement, there are 2 blind spots in our vision where our optic nerves connect to our retinas that we don’t perceive, and our brain invents the color that we perceive in our peripheral vision, which cannot physically be detected by the eye. Vision is weird and complicated.




  • You’re describing a typical budget CRT, and like typical budget flat screen panels today, they did suck. BUT…

    CRT is a superior display technology and high end tubes have only recently been maybe matched in quality by specifically OLED. Manufacturers did not switch to flat panels because of superior quality, they did it because they are much cheaper to manufacture, handle, transport, and are more appealing to consumers due to energy use, weight, size/aspect ratio, and less configuration.

    I have a Trinitron tube, which runs at 1600x1200@85Hz native (nearly the same number of pixels as full HD) and can be run at significantly higher resolutions, or lower resolutions at significantly higher Hz.

    You mention flicker, which is a problem for typical budget low Hz CRTs, but is not a problem for better, high Hz tubes.

    wider color gamut, more accurate colors, higher contrast ratio

    Plainly incorrect. OLED is the first flat panel technology to basically match a CRT in image quality. CRT shows true black and near perfect color, they also can display any resolution without interpolation because they do not have pixels (a 720p image/video will look absolutely terrible displayed on a 1080p flat screen, but perfect on a CRT), and CRTs partially activate posphors for a more accurate image detail than the equivalent discrete pixel resolution. My Trinitron tube’s detail is only limited by the spacing of the aperature grille, not the number of posphors. So comparing resolution is kind of apples to oranges. And this is why old low res games did actually look better on a CRT than they do now when played on modern flat screens. Example (this example uses a slot mask, not aperature grille, but still shows the effect of partially activated posphors):

    There are real benefits to OLED (weight, size, wide aspect ratios [wide aspet ratios are only better for watching movies or TV though, worse for playing games or productivity/web browsing], energy use, gimmick refresh rates, gimmick resolutions like 4K and beyond), but picture quality is not one of them.

    The biggest benefit to a CRT for me, besides true blacks, is input latency for competitive gaming. I don’t understand how people can play games on flat screens with the cursor lagging behind the mouse’s true position/movement. I guess you just get used to it and your brain adjusts for it, but having only really gamed on CRT, it is horrible any time I sit down at a friend’s computer to play something.



  • PS my guess about the intense look is because she is experiencing “zero-G”, which allegedly feels identical to a free fall drop or that moment you crest a hill at speed and your stomach feels funny. I would probably be very uncomfortable and would struggle to appear serene or at peace while my stomach is floating inside my body
