Radius Pivot: The Rotating CRT Monitor from 1991 [LGR Oddware]

June 25, 2021 by 46 Comments



Taking a look at the Radius Pivot Full Page Display! You might’ve seen monochrome Radius Portrait displays for the Mac, which were permanently mounted sideways. But not the Pivot! It’s an SVGA color computer monitor that rotates 90 degrees for a vertical display in Windows 3.1 and MS-DOS.

    IT EXIST!!! My day can't go any better.

    10:13 that's like an optical illusion lol It gets more rectangular as it turns. It starts out very square looking then you rotate and it's rectangle af

  3. Kevin Bhasi says:

    I didn't know there was a PC version of that monitor! I only saw info about the Mac version prior to this video.

  4. Xeperu says:

    Had to turn my phone to landscape in order to see footage of portrait better… so meta.

  5. I JUST bought a rotating display at Goodwill a few days ago! It wasn't a CRT, but since then I've been in a "rotating" mood.

    Clint's intense stare during the intro animation is strangely amusing

  7. Richard Page says:

    I'd play Raiden and other vertical shooters, perhaps do nefarious things with DS software…. my eyes aren't suited to tiny screens.

  8. Thinking about vertical shmups right now

    Who does your Closed Captioning?!

    [oddly jazzy intro music] 😂

  10. There is some Eno video art back in the day that needed the TV to be on its side. This monitor would be perfect for that 🙂

  11. Noah Neumann says:

    From the 90's, I'm surprised they didn't market this as an 8D monitor! 2D display plus 6D of swivel.

  12. Idelacio says:

    AutoCAD would be too complicated too do that kind of rotation on the fly for this era. Yes you can do that TODAY with modern 16 core machines no problem but it's already a system heavy application for 1991. You can see it needs to think about rotation when doing just documents, imagine trying to rotate the canvas and mucking about with recalculating the data arrays and no, no, easier to just reboot the software. Frankly you are probably not going to be rotating on the fly anyway so not much loss.

  13. Woofy says:

    3:20 – I see that Technology Connections video in the corner, Clint… I see you're a Deitz Nut as well 😉

  14. B4NCL4M says:

    Vectrex Emulation?

  15. CT1660 says:

    I come across these from time to time. Currently holding one for Mac84. For Macs, it came with a LC-type PDS card and sold as the ColorPivot

  16. Unix 2816 says:

    Normal monitor to Xerox alto monitor with this one simple trick !

  17. j2simpso says:

    You showed us portrait mode and demonstrated landscape mode as well, but I'm a bit disappointed you did not demonstrate the so-called Portscape mode (monitor swiveled between portrait and landscape mode). How do the windows adjust to that diagonal orientation? 😅

  18. PIVOT! PIVOT! PIVOOOOT!

  19. WRO says:

    Adjustable monitor. Kids, this is the prehistoric ancestor of the cellphone.

  20. Smmmile:) says:

    Only an idiot would pay that much to rotate a square.

  21. Just say A4 paper bro

  22. Rabid Koala says:

    We gotta get Game Sack in on this. He'd blow his mind over the TTAAAATEEE MOODDDDEEE capabilities!

  23. Ross Kelly says:

    I still have a LED monitor that does this, so cool!

  24. 🤘😁🤘

  25. Feels a little bit like this video is lacking the Solitaire finishing animation in portrait.

  26. Junu Jeong says:

    Haha wow what a design

  27. Argus Swift says:

    The turn squeak reminds me of Civvie getting shocked.

  28. Jacob Ortiz says:

    Dose the monitor work in Windows 95?

  29. The Kobra says:

    .28 dot pitch was the norm back in 1991.

  30. flying toasters in portrait mode please 😀

  31. Jase Poag says:

    3:20 I see you watching the recent Technology Connections episode over there.

  32. s8wc3 says:

    I have a modern day NEC 2190UXP monitor that has a built in sensor that will rotate the screen automatically, it doesn't work nearly as smoothly as this though. Still amused me.

  33. Radix says:

    These must have been slightly more common in the next few years. A dude in my dorm had one in 1996-1997? Still uncommon, but affordable for a student.

  34. Cacoe says:

    30 years later and it's easy to rotate any monitor, piles of them come with stands that will swivel, if not you can buy a 3rd party stand – yet none of them auto rotate the content of the OS and it's infuriating.

  35. StevenSmyth says:

    The Mac versions of these didn’t require a special card, just a Desk Accessory (pre System 7) or a Control Panel. The best card to use was the Radius 8-24 which was one of the first video cards that had 24 bit color. I had a Mac IIci and a color Pivot when I was desktop publishing. It was perfect for page layout in QuarkXPress.

  36. Has anyone tried MAME on this?

  37. Rival Minds says:

    [TATE MODE!!!]

  38. siskavard says:

    This would be awesome for MiSTer

  39. watching Technology Connections at 3:17, nice

  40. MS Thalamus says:

    Yeah I was disappointed by Microsoft Arcade's lack of scaling too. You can manually reduce the screen resolution to match is game window size, though. It didn't look squashed on the Radius though, so it might still look really good in portrait mode.

  41. But…. Does it run Xerox OS? 😁

  42. savagemadman says:

    I remember seeing those in the Mac section of Computer City back when I was little.

  43. meme GOD says:

    8:24 – 🌈🌈🌈🌈🌈 in 1991 🤦‍♂️🤷‍♂️😂

  44. AmstradExin says:

    Have you tried using software that supports regular VESA modes, like Image Viewers or Games? Like Quake or QPEG?

  45. Andrew Baker says:

    Ah. The "if Twitch existed in 1991" monitor. Lol

  46. I'm from Brazil and I can't speak English very well, but I really like your videos!!!
