mDP to VGA adapter limit at 1600x1200@60Hz

cube · Jun 18, 2009, 02:48 PM

OK, this is not cool. I bought the Apple Mini DisplayPort to VGA adapter and I cannot run my Mitsubishi DiamondPro 2070SB anything better than 1600x1200 @ 60 Hz.

This monitor can do resolutions higher than that, but 1600x1200 is the native, and I usually run it at 100 Hz from my Cube. 60 Hz is not good for the eyes/head with a CRT.

This is totally unacceptable.

Sounds like you may need some better drivers to allow for the correct options to appear.

cube · Jun 18, 2009, 02:52 PM

I already have the latest adapter firmware revision and even SwitchResX.

Is there an NVIDIA control panel?

geoffreak · Jun 18, 2009, 02:57 PM

Unfortunately CRT monitors are mostly outdated at this point, so I'd recommend getting an LCD if you need a better resolution (not to mention the crisper image from a DVI connection).
There is no NVIDIA control panel as Apple writes the drivers for the chip.

I don't want to get rid of my PRO CRT, which would be a hassle. I also needed for another old 4:3 computer and I got no more space.

Craigslist can reduce shipping costs to none

I'm not interested in getting a 4:3 20" LCD. I want at least a 1920x1200 24".
But I need to keep a 4:3 monitor.

Also, AFAIK, LCDs still don't match CRTs for color.

Using an IPS panel will give you nearly all the benefits of a CRT.

cube · Jun 18, 2009, 04:11 PM

There are no 25" 4:3 LCDs 1920 pixels wide, and it would be worse than a CRT at lower resolutions.

geoffreak · Jun 18, 2009, 04:21 PM

May I ask why you need a 4:3 monitor?

cube · Jun 18, 2009, 04:25 PM

I said I have another old computer (that can only do 4:3).

cube · Jun 19, 2009, 12:34 PM

Is any of the third party adapters any better? I see 1920x1200 advertised. Many brands just seem rebadges of the same device, and I also see "Apple firmware update required"

Is the DAC in the MBP or the adapter?

Thanks
