    Just tried to connect my lounge pc to my TV
    Initially it was connected via HDMI but I needed one of the 4 hdmi inputs for my Chromecast so decided to use the vfa input instead.

    I now have it connected using a vga cable at the TV and then a vga to DVI adaptor at the pc but I'm not getting any output.

    The adaptor (DVI a i think) doesn't have all the pins and the larger flat pin, do I have the wrong adaptor?

    There's a few kinds of DVI treacle.

    DVI - A - Carries Analogue Signal - can be converted to analogue (VGA) with a simple adapter like you used to get with most graphics cards.

    DVI - D - Carries Digital signal, can be converted to HDMI, DP etc without the need for an active adapter. Can be converted to VGA but will need an active adapter.

    DVI - I Carries digital and analogue.

    Look at the back of your card and you'll see what it has (I imagine DVI-D if its a recent card)

    Yeh I knew there was several different types.

    It's on a gtx 670 and looking at those images I have a DVI-I and a DVI-D.

    Plot thickens, I find what I think is a different adaptor and use that and the TV receives an input and displays windows.

    Only thing is it defaults to 1024x768 and the max I can bump it upto is 1680x1050 which looks really scratchy.

    Turns out the adaptor is the same as the other two I have as well so go figure on that one.

    So why cant I increase the res to 1920x 1080?

    Not silly at all, installed the latest earlier and no joy.

    It seems the tv may be limited to 1600x1200 on vga, think I may have to go the HDMI switch route, could probably just use a manual switch as its not often the lounge pc gets used.

    Got the TV model? Pull the specs up it should tell you, be surprised it only does 1600x1200 on VGA though if it does 1920x1080 over HDMI. Although I've seen 1080p on some TV's via VGA...it isn't pretty sometimes.
