[SOLVED] Refresh Rates that do not match Computer and Monitor - what happens?

[pcHobby]

My old Mac G4 dual 1.0 running OS 9.2.x lists 1920 x 1200 @ 76hz refresh rate that I can choose for monitor resolutions.
The 24 inch monitor I wish to buy only does 1920 x 1200 @ 60hz refresh rate, I have read that 24 inch monitors cannot go higher than 60hz at this resolution.

What happens in this situation? Does the monitor go blank if I try it, does the 1920 x 1200 @ 76hz resolution become not listed on the computer monitor resolution list?
I would like to know if its worth buying the lower refresh rate but larger monitor for my Mac?

What happens if it is the other way around - Computer resolution only list 1920 x 1200 @ 60hz refresh rate and the monitor does 76hz refresh rate?

Thank you.

76Hz would be the max that the video card can do. Unless you have it forced to use that, it should drop down to 60Hz. If it's forced to output 76Hz, then at least for PCs, you should see an "out of range" error.

CRTs could do faster than 60Hz. When LCDs came out 60 was it. There are a lot of gaming monitors now that can do 144Hz or more. You can totally get a 24" 1080 LCD monitor that goes faster than 60Hz. You normally want the monitor to be equal to the video card or faster so it can run to it's full potential. But I wouldn't worry about a76Hz card with a 60Hz monitor. (if for whatever reason you are, just spend the coin and get a 144Hz monitor.)

Edit: As you can see, there are plenty of 24 inch 144Hz monitors. I don't know who told you there aren't any, but they lied.

Thanks for the reply.

I am trying to share the monitor with an old Mac Pro and a much older Mac G4 and use a KVM switch. So if I were to buy a 27 inch 2160 x 1440 Monitor. How does it work with the Mac G4 that can only do a different smaller resolution 1920 x 1440 @ 75hz.

Will the 27 inch monitor just deform to the smaller resolution or will it become out of range/not show anything on screen or not include that resolution on the list of the Mac G4 under display settings?

The switch has it's own limits doesn't it? It might limit things to 60Hz, or 1080.

You'd be limited to whatever the G4 supports. You'd have to run the smaller image on the larger monitor.
