I've made the switch to a Mac Mini, and unfortunately it seems to be detecting my monitor capabilities incorrectly; how can I override this autodetection, or otherwise get around the problem?
I'm using a (relatively new) Digimate L-1705 17" TFT monitor connected with the DVI-VGA adapter.
The maximum refresh rate of the monitor is 75kHz, yet when the mini boots, the grey screen appears OK - but when it changes to the normal desktop screen my monitor reports a "signal out of range" error.
I think that the mini thinks that the monitor can achieve a higher refresh rate than it really can, and is using this by default. How can I stop it doing this?
I know that the computer works, as I carted it across town to my brother - using an old 14" CRT! This enabled me to register the Apple wireless keyboard and mouse, and set up a user profile. Whilst there, I set the display preferences to a setting that I knew worked with my monitor.
Upon getting home and connecting the monitor, I got the same out of range message.
Thus far, I've been on the telephone to Apple Tech Support for over 1h, and they've been able to come up with anything more useful than their presumably standard "reset PRAM, reset PMU, boot from CD, boot into safe mode" spiel - all of which I'd already tried, and none of which worked.
Their other suggestion was to take it to an Apple store - but unfortunately this will require me to catch a 100GBP flight off the little rock on which I live. Hmph.
Carrying the mini across town is OK, if there's something that I can do when connected to another monitor - but it's not feasible to carry my monitor across town as well. I don't have any other display unit (monitor, compatible TV, etc.) on hand which can be used.
I can get into the Open Firmware (command option O F) and have had a poke around... is there anything in there (or accessible from there) which I can change to set the default screenmode? I can see the HD, but have no idea how to find/edit/remove files from the OF command line.
I can also get into the single user mode (command S) but unfortunately once I'm in there I can't do anything, as the Apple wireless keyboard is not detected. Great! I'll happily buy/borrow a USB keyboard if necessary (my PC one is - typically enough - PS/2).
There are some instructions
on the Apple support site, but unfortunately this doesn't work in my situation - safe mode goes out of range, and I can't type anything in single-user command line mode!
, again on the Apple suport site, appears to be my exact problem, but I don't have the option of using a compatible CRT screen and my TFT at the same time.
I've also found a bunch of useful information on ars technica
but none of it has helped with this problem. I've posted my question there, too - but have had no joy yet.
I appreciate that I've typed an awful lot so far - apologies! - but when it comes to things like this, I know that it's best to explain the minutiae of what's wrong and what has been tried... Hopefully there's someone here who knows everything there is to know about the underlying Mac architecture, workarounds, etc. - please?! (I've currently got every possible extremity crossed on the off chance that it helps...)
Many thanks in advance!
On preview: Hehe - "Extended explanation"... yup!
