    Blurry Picture through KVM Switch

    I bought a £15 off-brand KVM switch from a local PC shop but when I plugged it in and fired it up the picture quality was awful. I returned it for a refund with no hassle, but I'm wary of buying another one from another shop in case I have similar issues and grief returning it.

    Can anyone reccomend a cheap but decent one?

    Nifty, cheers.

    From the picture it looks like the switch itself has seperate ports for a USB mouse and keyboard but only 1 USB connector for both connecting to the PC - is that the case?

    I'd be getting the ps/2 version to keep my old clicky keyboard anyway but I'm curious.

    Should be OK I'm sure, it's the same data for the picture regardless and I can't believe I'd notice input lag from an extra metre of keyboard/mouse wire.

    KVMs have a max resolution that they can handle, for instance

    Belkin Omniview 2-Port KVM Switch with Cables, PS/2
    Supports video resolution of up to 1920x1440@65Hz

    can take a bit of hunting to find the info though.

    Only be at 1280*1024 for now at least.

    I do have a big old CRT that can do 2048*1536 but that's for my TV box, the KVM is for 2 different machines that need to share a monitor.

    A mate was trying to run one and found for his setup the frequency was more of a problem than the res.

    I don't get why there should be a problem with any resolution or frequency. Surely on the display side we're talking about good ol' VGA cables with a physical switch between them.

    I still don't understand how the one I bought managed to screw things up.

    It's all to do with the way the way that the VGA is switched and the type and quality of the actual switch.

    Think of it along the lines of a conventional switch, if when switched it makes bad contact then you'll not only get heat build up which in turn will effect the actual signal being switched.

    blurry was because of REFRESH RATE...bet money on it

    KVM;s are supposed to remember the refresh rate, but you DO have to set it in the first place

    AFAIK, the refresh rate is set by the PC/Vid card, the cheaper KVM's simply switches the output, I have had el-cheapo KVMs give me a ghosted image which obviously looks blurry.
