Hi everyone. I recently purchased a 2007 macmini. I have it hooked up to a HP 16:9 ratio full hd monitor. My issue is that when selecting the resolution and refresh rate there is a black line down the left side of the monitor from the edge until about 2 inches in where the output starts. I have found another thread online but none of the suggestions have so far worked. (resx, changing cables, resteting pram). Hoping somebody can help me out. Thanks.
