    Epson EP410W - image wobble

    Hi Folks,

    hope you can hope me out here... I have 5 Epson EP410W´s installed in classrooms (some are the education model 410We). They are all suffering from a very small, but very distracting, image wobble. Its only a few pixels... but...

    We are running various different monitors on the different PCs. Some are running at 1280x1040 others a more wide screen format. Each PC uses a Converge AV ST122LE usb powered video splitter to maintain colour and brightness.

    Any suggestions please on what to do?

    Many thanks,

    Tony.

    NB: We use the same VGA splitters on other older projectors and on various Epson EP440s without any problems.

    It sound like magnetic radiation from a device are they near any form or motor or industry?,
    is your supply voltage stable?
    does it do it on menus display with VGA unplugged?

    is there an induction loop for the hard of hearing anywhere near it? Are there any large speakers near the cable run? Is there any kind of large power cable near the VGA run?

    Hi Folks, thanks for the replies. I have just been round them again checking.

    1) There is no other electronic devices or cables near by, in the walls etc. only the ones for the projector and the IWB.
    2) The wobble is not happening on Menu - the Menu actully makes it stand out even more as it is dead still.
    3) No induction loops etc either.

    I have also now got shadows appearing on some of my projectors. (Epson 440s)....

    1) I think the shdows are most likely to be bad quality cables, I have fitted powered VGA splitters (VGA Video Splitter - 2 Port | With Audio | Compact Design | StarTech.com Europe) to nearly all my units now and this has got over many of the poor colour and loss of signal problems. BUT I have also had some wall mounted socket distribution boxes fitted recently and some of the shadowing has started after these have been fitted. I think it is most likely to be some kind of ghost image created by a badly terminated wire somehow... but no idea what to look for? Some of the cables need to be replaceed as I am left with some 10m cables being used for 1m runs...

    2) The wobble... again, I think some kind of bad termination or poor quality cable. I might try running a brand new cable without putting it in the trunking and see what happens... maybe the mains cable in the trunking are also causing problems to the signal...

    Many thanks,

    Tony.
