red tempo Level 1 Level 1
I'm running my mini through an LG 42" plasma TV using a store-bought HDMI to DVI cable, and I had the resolution at 1344x756.

After I did the most recent update for what I assume was Leopard 10.5.7, my resolution and colour quality changed. Now with overscan on the picture is cropped and the dock is almost out of view when I hover over it, and with overscan off there is a black gap of about an inch framed around my screen. The only change ocurred after I reset the computer post-update. I tried re-installing the update and messing around with the cable connection to no avail.

What are the odds that it was the cable? Is there anything you know of to roll back updates? Has this happened to anyone?

Mac Mini 2008, Mac OS X (10.5.7), 42" LG plasma TV as display using DVI to HDMI cable.

    Absolutely the same story here using 40" Sony Bravia. Everything looked perfect until the most recent OS X update which I performed today. It seems like Overscan is not working properly.

    The same thing here. My mini used to display at 1080p on my 42" Westinghouse, but after the update it only does 1080i. Not only does it look wrong (top and bottom cropped) but it flickers and jumps a little.

    I looked at the color profile file (WESTINGHOUSETX-42F430S-2144FE00.icc) in the color sync utility. It says it was created on 4/30/2009 at 8:20:34pm, so I'm guessing they put new and "improved" drivers in the update along with the profiles.

    Is there a way to downgrade? I'd sure like to have my nice, smooth, un-jerky display back...

    Same problem here with a Sony 42" WEGA Rear Projection HD. Everything was fine until I just updated to 10.5.7

    I have exactly the same problem running on a Sony LCD HDTV with a Mac Mini after the update.

    Not good I guess we have to wait to Apple to Fix this???

    I have exactly the same problem, on a Sony 36". With overscan on, I can't see the menu bar at the top of the screen, and lose a lot of the dock. By turning overscan off, and fiddling the display settings on the TV (altering area to -2) I can get it so it uses up more (tho still not all) of the screen, with all the bars etc.

    I could live with this, however it also seems to have screwed up the res. No matter what setting I use the fonts look fuzzy and hard to read. The tv screen was never quite as crisp as the monitor on our iMac, but I could read an e-mail without feeling nauseous.

    Hoping Apple will fix this....

    Me to! Let us know if you find a solution!

    Apple: This needs to be fixed, my TV isn't displaying a picture anymore!
  • ehhayden Level 1 Level 1
    Ditto re the upgrade from 10.5.6! The best choice (non-interlaced) is 1280X720.
    My display is Samsung LN-T2353H (or 2354H). However, there is no way I am
    actualy getting that res. My best description of the text and images is that they're "gritty". Text is difficult to read. The image was excellent before the
    upgrade. The degradation happened immediately upon re-boot. Is it possible
    to back out the "upgrade" (I didn't backup!)

    Here is a link to an article with some downgrade strategies...
  • Kassinen Level 1 Level 1
    same problem for me after the update, overscan gives a picture that is too big and without it the picture is too small plus a fuzzy picture nowadays. Has anyone heard anything official from Apple? I sure hope they have heard of this problem and are working on it!
  • Gaffer-man Level 1 Level 1
    Again, same issue here. Obviously Apple broke something in the latest update.

    Please Fix or at least give us instructions on how to back out the latest update!

    Same problem here.....

    Sony KDS 50A2020 DLP TV w/ a brand new Mini.

    Funny, Fedex delivered my refurbished 2009 Mini this afternoon, everything else worked like a charm but I have been fideling with the TV display and Display Preferences all night!

    Anyone here recommend settings?
  • Clootie Level 1 Level 1
    Thank you to BSteely above I have now reverted to the pre-update.

    Using the link BSteely provided, I followed the instructions to revert to old system (basically, do a reinstall of Leopard from the original discs, choosing archive option to keep all your files & settings, then download a combo update up to 10.6 - link provided in that article). It's taken several hours, but it works.

    The picture now fills my TV screen, but best of all my eyes have now stopped bleeding!

    Same here - Samsung 42" working perfectly until the 'upgrade'. Worst of all it is on a system I'd especially set up for my parents, one of whom is very ill. The big screen was perfect for them, and also made it easy not having a separate set up somewhere else in the house. I live 150 miles away, don't have the system disc with me on a visit and won't be able to get back to downgrade it for at least two weeks. Thanks Apple!

    Well, my solution was to move my connection to the DB15 (PC) connector
    to achieve a desired resolution of 1360X768. I moved my old PPC
    laptop running 10.4.X to the hdmi connector. Now they both work fine.
