Plug an external monitor and see if it works. If it does, that could be a dead LCD or a busted cable. If it's the same, then it's your GPU/Logic Board.
If you’re getting an iMac get an AppleCare too. At least you’ll get 3 years out of it. Then you’ll start paying for repairs!
Planning to buy iMac 21" next month. Should I buy or should I wait for the new one? Planning to get this config: 3.6GHz quad-core 7th-generation Intel Core i7 processor, Turbo Boost up to 4.2GHz 32GB 2400MHz DDR4 512GB SSD Radeon Pro 560 with 4GB video memory Magic Mouse 2 Magic Keyboard - US English Accessory Kit
Thanks for the input! Was thinking about it but with the config I want, there would be a huge price difference if ill get the 27" Kinda torn if I should sacrifice i7 to compensate 5K retina :/
^Let us know what you'll do with that computer, so we can tell you if that processor (i7) is overkill or otherwise.
Ill be using it to edit photos (Lightroom, PS, CaptureOne, Skylum) and few travel videos (Final Cut, Adobe Premiere). Aside from that, office work na po hehe. Still waiting for the new iMac if there will be one. Another option im thinking is to get a mac mini and buy a monitor. Any suggestions pls?
^OK.... with those mentioned, an i5 (Quad-Core) could handle those seamlessly. You will benefit more on "more RAM" and/or "SSD," than a "better" processor. If you throw in 32GB to that, video editing should not be a problem as well (unless you do Pixar stuff). Gone are the days when the CPU handles 75% of the job... these days, GPU does more work than CPU. = that said, Mac Mini would not be an option.
