Cintiq 20WSX Snow Leopard Workaround
Posted August 31st, 2009 in Illustration.
Here’s the problem. Snow Leopard is seeing the Cintiq’s default refresh rate higher than its native 60hz. Using a third party app named SwitchResX, I created a custom 1650×1080@60hz resolution. I rebooted my MacPro, applied the resolution setting in the Display SysPref PrefPane, and, voila, no more problem.
An official fix would be nice, though. Hear me, Apple & Wacom! Old man Frenden shakes his fist at you with scorn and malice!

Nice one Ray!
Is the gamma ok? I was never happy with the gamma on my 21UX and have just learned to accept it, moving my work over to my cinema for final tweaking.

Ah thank you for this! I just installed Snow Leopard and had a mini freak out at why my Cintiq resolution was so low.
You have saved my eyes~!

Dwayne, the gamma seems better than before. Apple did switch to the PC standard and away from their old default gamma too.
Psyc, no problemo! I saved my eyes too. ;p

any chance of getting your custom settings?
when i choose custom resolution and add in the 1680×1050 native 20wsx resolution, the refresh rate seems to automatically adjust to something under 60hz
and do i need to worry about front porch, pixel clock?
thanks for any help

I didn’t adjust either porch or clock; I just created a 1680×1050 resolution, input 60hz (and it did adjust to a slightly lower number than 60 for one of the options – horizontal or vertical, I can’t recall and am on the road at the moment). It works fine.

Regardless of connection type, with computer and Cintiq20 turned off, flip the switch to the VGA position. Power on the Cintiq20 and then power on the Mac. It will let you set it to 1680×1050 @60Hz. This happened a bunch with original MBPro on the NVIDIA 6800 Mobile card, and it was the advanced timings like you can adjust in your SwitchResX app. Now it will happen on Intel and NVIDIA cards. PC users with similar issues have specific video card drivers and CPL interfaces with the ability to adjust this built-in… too bad Mac does not. It’s likely got something to do with the EDID info coming from the Cintiq20 and what 10.6.x does with that info. Will test SwitchResX as well and see how that fares with Cintiq20 switch in DVI position.

While SystemResX might be a pain in the %&@# it seems to work rather well, but is only a trial. Looks like you need to buy it.

Not sure if anyone still reads this, but does anyone have, or has anyone seen, this happen on ATI cards? Or is it just NVIDIA and Intel? Thanks,

Yeah, I’m having the same trouble on my brand new Mac Pro….display will let me set at 1680×1050 but everything looks really pixelated and bad. Anyone have any suggestions?

I installed the original solution at the top of this screen….and….no luck….

Ok….spoke too soon. After a reboot (two times) everything works perfectly! Thanks for your help!

Yeah. SwitchRes isn’t the most user friendly application. It does seem to be the only solution at the moment. Boo hiss.
