Hi Mac Rumors. I've got a Mac Pro 5.1 (2010) & 30" Apple Monitor (OSX 10.13.6 High Sierra) that I'm trying to watch 1080p & 1440p video files. My poor ATI Radeon 5770 graphics card starts to blotch out with 1080p and 1440p makes it supper blotchy with un-smooth motion. I'm not a gamer or am...

Hi there, I'm hoping someone can help - I'm experiencing a strange fan issue with my graphics card that I purchased in 2020. It seems to intermittently turn on at the highest speed at random intervals - I've also noticed that just one fan does this instead of both. In fact, one fan isn't even...

Had this issue in the past sometime but haven't found an explanation yet. There's a persistent rectangular artefact on the bottom left of the screen on Desktop 1 but not on Desktop 2 (see picture). When Desktop 1 is deleted, it moves to Desktop 2. SMC and NVRAM were reset a few days before this...

Original Question I have an old Power Macintosh G3 Minitower (266 Mhz) and I'm looking to install a GPU upgrade so the G3 can output higher resolution video at higher color depths. However, I don't know of any specs for what the max working graphics card specs (mainly VRAM) work for a beige G3...

Our 2018 MAC MINI SG/3.0GHZ 6C/8GB/512GB can be very slow when using the Cintiq 22 inch with Photoshop and animation programs such as ToonBoom Animate etc. A friend suggests we buy an exterior graphics card, plugging it in to one of its Thunderbolt 3 (USB-C) ports. Is this a good idea and can...

A while ago I bought 2 new Samsung monitors to run on my 2008 Mac Pro 3,1 with a GTX770 graphics card. I unplugged the old monitors, plugged in the new ones (using Samsung's supplied HDMI cables, the only ones I've found that will actually run them at their full 144Hz speed). One of the screens...

Hello All, I've spent weeks scouring the internet but I can't find the answer to this question: Does the dead display of an iMac or MacBook use any CPU/GPU power? For example, I have a Mid 2012 13" MacBook Pro with a dead display that I've been using as a desktop (with an external display)...

It's an older (2010) 15" MacBook Pro I still own which keeps astounding me on how excellent it still runs after all these years, (I am not a gamer though). The only problem is it's manifesting some GPU glitches sometimes, like when opening some big sized PNG images on Preview (not always...

Here's my specs Thanks!
