    Howdy.

    I am currently using a Mini-DVI to DVI adapter to connect my new 23inch HD monitor to my MacBook. I am just curious if there is any advantage (over what I'm using now) to using a Mini-DVI to HDMI adapter to run an HDMI input into my monitor? My monitor has Full 1080p HD capabilities. I guess I just don't know if I'm using my monitor to it's fullest capabilities with the DVI input. For some reason I feel like HDMI would take advantage of the HD capabilities. Can my MacBook even output a true HD picture? I have a 2008 Black MacBook, 250GB, 2GB Ram, etc.

    Thanks for help!

    dvi=hdmi without the sound

    the picture quality is exactly the same, just hdmi also transmits the sound

    It DOES and it IS outputting a true HD picture. Just make sure the resolutions are correct in the display settings. And make sure you're not mirroring the displays.

    Dvi

    Surely even using DVI-HDMI there will STILL be no sound as no sound is output at source.

    Stick with the DVI solution you currently use.

    HDMI is the better technology since it has much more bandwidth than DVI and can carry things like sound and higher resolutions. But in your case it would make no difference since you arent using anything that would benefit from HDMI and dont even have an HDMI port on your computer, DVI does 1080p just as well as HDMI.

    They carry the same resolutions

    All hdmi does is carry sound as well. The video is identical:cool:

    HDMI 1.3 supports the same resolutions as Display Port, HDMI 1.4 is even better and supports incredibly high resolutions and more than just sound.

    internet support, audio return among things

    HOWEVER, hdmi 1.4 is next gen, its like comparing usb 2.0 to usb 3.0. They do not use the same connections. In addition hdmi 1.4 wont even be around for a year or so so why are you even bringing 1.4 up stainlessliquid?


    Now to be relavent to the question the OP asked, being with the current hdmi, there is NO difference in video quality or capabilities between dvi and hdmi with your monitor in question

    You said they carried the same resolutions when they dont. You need dual link DVI to support resolutions greater than 1920x1200. HDMI 1.3 supports 2560x1600, HDMI 1.4 supports 4096x2160. HDMI and DVI may be similar in pin layout but they are not the same, HDMI is capable of bigger and better things.

    Thank you very much for all your replies!

    I ran into something also worth asking though.

    I have found that whenever I go to a fullscreen mode for something like a YouTube video, my CPU starts working and heats up really quick (up to around 170ºF). Also, when watching full screen things from Hulu, the video is really choppy and behind the sound.... Would HDMI help me out in either of these cases? Can HDMI output more data using less CPU or can it do it faster so my videos aren't lagging?

    Depends

    It also depends on the monitor. I read some reviews about some Dells that overscan the HDMI output by 3-5% which means you wouldn't be able to see the top menu bar if connected mini-DVI to HDMI. You also wouldn't see the bottom half of the dock (depending on the size that you set your dock.) This overscan is not defeatable (undoable) via the monitor's settings. In this case you will NOT have 1:1 pixel mapping, and the screen will not be as crisp as it could be.

    It all depends on your monitor, which you haven't specified.
    Therefore stick with the DVI input.
