    I assume the best way to connect a Mac mini to a monitor is by using the hdmi cable?

    Here are the specks for what should be your's or similar 2011 Mac mini:
    Video (Monitor): 2*
    Details: *1 HDMI and 1 Thunderbolt port.

    Supports 1920x1200 on an HDMI or a DVI display (using the included HDMI-to-DVI adapter) and 2560x1600 on as many as two daisy-chained Thunderbolt displays (it also supports a Mini DisplayPort display or even a VGA display (with an optional Mini DisplayPort-to-VGA adapter).
    Thunderbolt is backwards-compatible with Mini DisplayPort-equipped displays as well as adapters that are compatible with Mini DisplayPort (DVI, VGA, dual-link DVI and HDMI).
    Thunderbolt likewise can support other peripherals that use the Thunderbolt standard, which provides a maximum theoretical 10 Gbps of bandwidth in both directions.

    I'd still suggest trying out the SwitchResX.app that still allows a free trial as I mentioned earlier. (Some settings won't save or stick after a restart or shutdown in it free mode.)

    Sure cheaper than buying a new monitor if it works for your setup.

    Agreed Patrick. Turn over all the rocks before opening up the wallet.

    I tried that app. Unfortunately still no improvement. It's a great app though!

    Think I'll just see how it is for a while and then decide on a new monitor.

    Thanks for everyone's help

    Maybe pack your Mac mini and the HDMI cable down to a local store that will allow you to connect them up and test things.

    Maybe something got messed up during your last trip.

    Just a thought… especially if any warranty is still in effect.

    Just an update. Thought I'd give the VGA route a go and bought a cheap thunderbolt to VGA cable and hey presto! image is super sharp now! so I'm all sorted. Thanks for all the advice.

    Good to hear thanks T-K and it just goes to show that the often recommended connection method may not always be the best ó a big understatement in your case.

    But then again many HDMI cables seem to crap out for some strange reason which is I gather what you were using.

    Maybe try another one at some time just to see and/or compare to what you have working now.

    Quite true Bob.

    I was quite surprised in the resolution differences for that 2011 Mac mini according to what they show at:
    https://everymac.com/systems/apple/m...html#macspecs2

    Video (Monitor): 2*
    Details: *1 HDMI and 1 Thunderbolt port.

    Supports dual simultaneous displays -- 1920x1200 on an HDMI display or a DVI display using the included HDMI-to-DVI adapter and 2560x1600 on a Thunderbolt or Mini DisplayPort display or even a VGA display (with adapter). Thunderbolt is backwards-compatible with Mini DisplayPort-equipped displays as well as adapters that are compatible with Mini DisplayPort (DVI, VGA, dual-link DVI and HDMI). It also can support other peripherals that use the Thunderbolt standard, which provides a maximum theoretical 10 Gbps of bandwidth in both directions.
    So I'm assuming that tiger-kai is now using and getting the higher and sharper resolution using the Thunderbolt (or Mini DisplayPort)-VGA adapter(s).

    I guess I had my HDMI specs reversed, at least as far as resolution goes.

    Anyway, glad to hear it's now all working properly for them.

    Yes I tried a few different hdmi cables and they all produced a bad image. Iím on a lower resolution now with the thunderbolt but the image is fine and itís perfect for what I need now. I think itís on 1366 x 768. With the hdmi cable I could go much higher. I think the problem is the signal.... itís like using a scart or composite cable. Kind of like a crt tv.

    I found this thread

    https://forums.macrumors.com/threads...lurry.1902129/

    I was thinking perhaps this was the problem I had.
    I blame the tv. Itís just a cheap one we bought a few years ago. We are living in this place temporary so this tv with the thunderbolt cable luckily will do the job for now
    Thank you
