    Hi,

    So we have S10’s 1200LE’s all working ok over the WNOS but now we got 300 odd T10’s and when we connect them up using DVI direct to monitor all is good in the world, but when we use the vga adaptor to attach to a VGA monitor the DDC table is empty and the wyse defaults to a 1024×768 which is fine for newer monitors but we have about 200 odd people who its not fine for.

    I don’t know if its a t10 or firmware problem but has anyone else come across this? I know you can set the res on the program launch but I need it to work as a default so we can go to auto launch.

    Any info will be taken on board and tested!

    Thanks in adavnace.

    What colour adapters are you using, black or white?

    We found the Black DVI to VGA adapter caused an issue for us but the white ones were fine. Update to 7.1.127 cured the problem regardless of colour adapter.

    they are black. I think I have a white one I can test though!
    I am waiting for my login for self service to come back to me and I will upgrade then

    Thanks for you reply I will let you know how the white adaptors go

    yes that’s the issue then, took me ages to work out why half my fleet of T10’s weren’t picking up DDC. We even cut the adapters in half to see what the difference was, they are wired slightly differently I think.

    Ok weird one!

    When I attached the White adaptor with or without a vga cable attached the device turns off!

    So I can not test your theory sorry.
    I will have to wait for this Firmware upgrade and login to test that.

    Thanks

    is it an original Wyse white adapter? looks exactly like the black adapter i.e. not one from a PC.

    that is weird, we’ve got nearly 2000 T10’s with several hundred using the cream adapter.

    have you got a Wyse DVI/VGA cable splitter, this also fixes the issue.

    Sorry yes but all being used at the moment.
    I will just wait till I get my login for the service porthole and then report back my findings.

    Thanks

    yep that’s em. both should work but DDC fails on the black one prior to 7.1.127. CIR is 65394.

    not sure why your cream adapter isn’t working though.

    Sorry, that’s the change number that refers to the fix within a hotfix:

    It was unofficially fixed within 7.1.127 with CIR65394

    but officially fixed within 7.1.130:

    CIR65018/TIR65033/CIR65619 Black DVI adapter is not working with DDC
