Wounded iMac

Video Scramble

My office iMac is having troubles today. Some months ago I had a problem where the the video would flicker then disappear. I suspected a video card problem because that's how the symptom appeared; broken and jittering video.

Software or Hardware

I disconnected everything from the computer, did a complete disk erase and resinstalled the OS and applications. Things seemed to have been sorted out.

I did a software upgrade and the problem is back. I don't know if it's related to the upgrade or just bad timing. I'm reinstalling the OS.

I don't think this is fixable by me.

Send in the Backup

I spent the better part of today putting an older iMac back in service in the office. This is iMac7,1 - a mid-2007 24"model with a 2.4 GHz Core 2 Duo processor. Not the fastest but should be find for web page building and testing. I have it running OS X El Capitan. This is the latest OS it can run and just gets me into the more recent MacOS features.

Testing image dimensions

I built some image rectangles to compare dimensions to screen sizes.

Screen test 400 x 100

Screen test 600 x 100

Screen test 800 x 100

Screen test 1000 x 200
