I was curious to see what my 13" rMBP would look like at full pixel resolution (2560x1600) so I downloaded the QuickRes app recommended by Macworld. QuickRes isn't made by an approved developer but I downloaded it anyway. My question is whether running my rMBP at resolutions that exceed what Apple builds in to System Preferences can somehow hurt my computer? Like could it fry out the integrated graphics card or something? While I can see why Apple doesn't think it's necessary to allow you to run at 2560x1600 (everything is super tiny), I could use it in some scenarios where I want all that space. So, could I do any damage in doing so?
