If you've got an ultra wide monitor, maybe spin it and go for persistence of vision effect and a huge circular display? Could double as a fan to help spread all the heat generated by the GPU having to redraw it nonstop!

- Y_Y 3y agoOne day such a thing might be so common that society will be forced to invent an abbreviation for that
- lanternfish 3y agoAnd maybe even one day, the abbreviation will become so ubiquitous that it becomes divorced in practice from the original referent.
- Y_Y 3y agoLol
- riwsky 3y agothis hertz to think about
- fudged71 3y agoThere was a “spinning gaming monitor” on my YouTube feed just a few days ago: https://youtu.be/J6P3o6zrqsc?si=NUB7YviQNYoSW7Vi https://youtu.be/J6P3o6zrqsc?si=NUB7YviQNYoSW7Vi
- HarHarVeryFunny 3y agoNeat, but imagine the sheer fear factor of a 34" ultrawide monitor whipping around at 60Hz 18" in front of your face!
- graypegg 3y agoAdrenaline is good for gaming!… I bet? If you have it going 3600rpm for 60hz uh… θ axis refresh rate (?), you have a pretty tough monitor. Now I’m wondering if you could mount it to 2 really fast linear actuators perpendicularly attached each other. One connected to the desk vertically, and the other fixed to it, with its business end mounted to the monitor. Now (considering the monitor doesn’t explode from the inertia) you could tile an area larger than the monitor itself. Could even adjust on the fly, so you can drag a window off the screen and it just starts vibrating more and more violently.
- HarHarVeryFunny 3y agoYes, that sounds truly terrifying! :) Combination of vibrations and actuators fighting the gyroscopic effect of the off-axis spinning monitor would risk the whole thing violently ripping itself off the desk. Would certainly be exciting!
- BuildTheRobots 3y agoI feel the need to point out that this is why mechanical TV never scaled. From very old memory, if you wanted a 40" screen then the wheel needed to be two stories high.

- Dylan16807 3y agoMost compositors already do redraw constantly, because it takes almost no work on a modern chip. An extra shift and rotate would not be noticed.
- HarHarVeryFunny 3y agoWell, normally only when something changes. For a rotating persistence-of-vision display you need to redraw everything as soon as it's physical position has shifted a "pixel". i.e. non-stop, regardless of whether the content has changed or not.
- Dylan16807 3y ago> normally only when something changes Do they bother? Throwing a dozen windows together is really easy. > For a rotating persistence-of-vision display you need to redraw everything as soon as it's physical position has shifted You do have to redraw. Which means you have a non-moving buffer that covers the entire display area, and you have to render it to the screen every frame. That's one big quad. A scaled up SNES could do that with mode 7. It's utterly trivial.
- HarHarVeryFunny 3y ago> Do they bother? Sure - it's not a matter of bothering to do an optimization, but rather just the way things work. Any applications running will only redraw on event driven basis when something happens to change the way it wants to appear (user input, timer, etc). The window manager will only recomposite/redraw on event driven basis when something happens to it (windows moved/resized/etc). Sure the GPU can handle it, although redrawing a 4K pixel display at 60Hz is still no joke. Even if you do something as simple as playing a video full screen on a large monitor you'll see GPU temp increase.
