maximum viewable resolution for mac os 9?

[supernova777]

just wondering what the biggest possible graphics resolution would be??
strange ive never thought of this before

is it possible to get 1920x1080 or above?
what resolution do u run your macos9 at!!?

[MDD]

I run Mac OS 9 at 1680x1050 - 20” Apple Cinema Display 

[Knezzen]

Using one MDD with a 1920x1200 screen without any problems in Mac OS 9. I don't really think that there is a resolution limit in Mac OS 9.

... may be 1920x1200 is max resolution on Mac Os 9 ...

I'm using 1680x1050 on a 20” Apple Cinema Display connected to Ti4600 in a MDD,
and 1920x1080 on a 22" Asus display connected to Radeon 8500 in a Sawtooth,

[MDD]

I also have an Apple Cinema 30” but I can not test it on Mac OS 9. It is connected to a Mac mini with OS X.

You'll need a graphics card with a dual-link DVI connector, otherwise you'll only get 1280x800.
I don't know if there ever was a graphics card with DVI-DL that had Mac OS 9 drivers.

[supernova777]

1680 x 1050 is a great resolution i think
i also have a screen this size and was using it with my mdd and it was great

nope, geforce 5, G5.

only with analog connectors you can go above 1920x1200, because that is the limit of DVI.

Or with Dual link DVI. Like the PowerMac G5 with Geforce 5 you mentioned has.

MDD, ATI Radeon 9000, 23" Cinema @ 1900x1200 and 20" Cinema @ 1680x1050 Extended Display mode

All day long…

One Important note is that only the Lucite (clear plastic) version of the 23" will do 1900X1200 in OS 9, the aluminum 23" Cinema will NOT go that high in OS 9, only in X

i dont understand this comment. nor how it is releated to the article you link to.

a G5 can not boot OS9.

[cw48494]

Quite limited, we're stuck with 1920x1200 using any G4 supported GPU.

Hmmm… I didn't know that - maybe time to start looking for a spare!

Here's another bit of aggravation: My 23" is on a KVM switch between the MDD and my El Capitan-running Macbook Pro.
As of Yosemite, for absolutely no good reason whatsoever, the Lucite Cinemas were deprecated in OSX monitor prefs and controls are no longer available for them.
I can tolerate this in my setup only because the display "holds" whatever it's set at by the MDD, but without having an older OSX to make adjustments, they would be hard to live with.

Just another friendly reminder from Apple that you're not spending enough money endlessly upgrading.

No you actually spend to much in the wrong direction.

OK class… explanation time:

Knezzen knows a G5 cannot boot OS9.
He merely refers to the type of DVI it has.

Now watch:

1) DVI resolution tops out at 1920 x 1200
2) In order to exceed that, there's dual-link DVI. Dual-link means there are TWO independent video streams on ONE connector
3) The 30" Cinema Display likes 2560 x 1600
4) In order to get that much from computer to display, Macs with dual-link DVI cut the picture in half - sending 1280 x 800 down each link
5) That's why if you connect a 30" to a computer with only a single-link DVI, you can only get 1280 x 800 max
6) Could Apple have made the 30" capable of also displaying 1920 x 1200 single-link?
7) Of course (and actually, I wouldn't be surprised if it can), but that would be too easy…and reasonable…and less expensive

Because THEN, you'd be able to buy a new computer and NOT have to buy a new monitor also

Any questions?

Correct!
