fixed : MacBook’s external monitor screen stays black

Question :

In my office, I am using an external monitor as my main screen for my MacBook Pro. Today, the screen didn’t respond when I connected my MacBook however : the screen stays black and nothing appears on-screen. So I opened up my MacBook and used the built-in screen to figure out what’s wrong, but so far I haven’t found any indication in the Displays Preference Panel that my MacBook even detects the second screen…

What can I do ?

 

Answer :

In such situations you should always do this first :

Remedy #1 :

  • make sure your monitor is switched ON
  • then hit the SPACE-bar on your external keyboard several times (maybe once, usually about 5 to 10 times…)
  • the monitor should now appear and show the inlog panel to unlock your screensaver
  • then login

if this works, you’re good, if not, try Remedy #2

NOTE : if you have a Benq monitor (especially the BL2420TP), try this first :

Remedy #2 :

  • unplug all cables between the monitor and your Mac ( DisplayPort / Thunderbolt / HDMI / DVI / VGA  and also USB, UTP, FireWire and PowerAdapter )
  • shut down your monitor
  • shut down your MacBook
  • reconnect all cables and double-check if they’re properly connected on both the Mac and the monitor
  • switch on your MacBook
  • switch on your monitor

if this works, you’re good, if not, try Remedy #3

Remedy #3 :

  • on your MacBook, open Apple [main menu bar top-left] –> System Preferences
  • in the System Preferences window, select “Displays”
  • in the Display Preferences window, see if there is a button marked “Gather Windows” bottom right
  • if there is no “Gather Windows” button, press the ALT-key on your keyboard and a button marked “Detect Displays” appears ; click on it when it appears

if this works, you’re good, if not, try Remedy #4

Remedy #4 :

  • on your MacBook, open Apple [main menu bar top-left] –> System Preferences
  • in the System Preferences window, select “Displays”
  • in the Display Preferences window, see if there is a button marked “Gather Windows” bottom right
  • if there is a “Gather Windows” button, click on it
  • then you will see 2 Display Preference windows on your MacBook screen
  • select the Display Preference window that has 3 tabs on it marked “Display”, “Arrangement” and “Color” (not the window that has “Display” and “Color” only)
  • first, press the ALT-key on your keyboard and a button marked “Detect Displays” appears where the “Gather Windows”-button used to be ; click on it when it appears
  • if your monitor switches on, you’re good, if not…
  • click on the “Arrangement”-tab and in the next window put a checkmark at “Mirror Display”
  • if your monitor switches on now, uncheck the “Mirror Display” option again and close your MacBook… you should be good now…

if this didn’t work, try Remedy #5

Remedy #5 :

  • unplug all cables between the monitor and your Mac ( DisplayPort / Thunderbolt / HDMI / DVI / VGA  and also USB, UTP, FireWire and PowerAdapter )
  • shut down your monitor
  • shut down your MacBook
  • reconnect your Mac to your monitor using a different type of cable then you normally would choose (e.g. if you normally use a DisplayPort/Thunderbolt-cable, use an HDMI or DVI cable now)
  • switch on your MacBook
  • switch on your monitor
  • if your monitor wakes from sleep now, open Apple –> System Preferences
  • in the System Preferences window, select “Displays”
  • in the Display Preferences window, see if there is a button marked “Gather Windows” bottom right
  • if there is a “Gather Windows” button, click on it
  • then you will see 2 Display Preference windows on your MacBook screen
  • now, remove the monitor-cable that you have just used to connect your MacBook to your monitor
  • then, reconnect your MacBook to your monitor using all cables you normally use to connect the two
  • if your monitor now wakes from sleep, you’re good
  • if it doesn’t, restart your monitor
  • it that doesn’t help, restart your Mac

normally your issue should be resolved by now…

if still the monitor stays showing a back screen, I’m sorry to inform you that your screen probably has a hardware problem… if so, get an authorized Mac-repair-centre to fix it, get the Apple Store support-crew to fix this…

that’s it !

enjoy 😉

fixed : repair or replace broken 24″ Apple LED Display ?

Question :

Just a few hours ago, the 24″ Apple LED display that I have connected to my 13″ MacBook Pro (Late 2011) started smelling… the odor was giving me a headache as if something plastic or electrical was burning… now, my beloved Apple Display is not showing anything on screen anymore : even though it’s USB-ports, the MagSafe-power and the sound are still working, and my Mac still detects a connected external screen, the display stays black…

What can I do ?

 

Answer :

I’m sorry to bring you the bad news : your beloved Apple Display is a ‘total loss’… Even though this could probably be fixed by replacing the internal ‘motherboard’ of your monitor (99% chance some component on it burned, which is getting an increasingly common problem with these 8 year old monitors…), the fact that Apple does no longer supply any new components for these LED Displays makes that no official Apple repair station will do any repairs on it any longer, and even if you would be able to find a working second-hand replacement part, the replacement procedure is so delicate that it is not a do-it-yourself job… don’t go there.

So you want a replacement ?

Apple does no longer produce or sell any “Apple Display”-monitors. The only monitors available for sale on the Apple Store are LG-branded 4K and 5K monitors… these are said to be co-developed by Apple, but BEWARE : these can only be connected to the most recent Macs that have Thunderbold3-over-USB3 !!!

For older Macs that have miniDisplayPort or Thunderbold (which is Thunderbold1-over-miniDisplayPort) you need something else…

If you just need a plain ‘extra screen’ of GraphicDesigner-quality, you could choose any monitor by Dell, Acer, LG, Samsung, etc. that gets good reviews by graphic designers and meets these specs :

  • IPS-type screen (which has a far better viewing-angle then the TN-type screens)
  • miniDisplayPort, DisplayPort or DVI input (not HDMI-only)
  • a black and/or minimal bezel around the screen
  • preferably as much or more pixels than your Apple Display (the 24″ Apple Displays had 1920×1200 and the 27″ Apple Displays had 2560×1440)
  • preferably an internal USB-hub (to connect an external USB-keyboard, USB-mouse or USB-scanner)

but for most of you, since you are still hanging on to your not-so-new MacBook, you will want an affordable replacement that will still be useful when you buy a new MacBook…

…then there is only one good option for you at this current time :

the BenQ BL2420PT monitor ; buy it at Amazon.com, Amazon.co.uk or Amazon.de

with a StarTech 4K@60Hz miniDisplayPort-to-DisplayPort1.2-cable ; buy it at Amazon.com, Amazon.co.uk or Amazon.de

BEWARE : there is no displayPort-cable included with the BL2420PT monitor, so don’t forget to add a 4K@60Hz capable miniDisplayPort1.2-cable

…okay, this is no way comparable to the sleek industrial design (the ‘box’) of your Apple Display… you won’t get MagSafe-power connection and an iSight webcam built-in, the screen is not high-gloss and it’s bezel is about .5cm thicker than the screen, the monitor speakers volume can’t be adjusted from your keyboard (you should do that on screen or use your Mac speakers) and you won’t get the ‘one cable’ connection you’re used to…

…but, it’s non-intrusive black, the screen can be easily adjusted in height and can even tilt to portrait, it has the 27″ amount of pixels on a 24″ screen (admitted : even though that’s a PRO for most, it might be a CON for some), it has built-in speakers, it has special settings for CAD/CAM and AnimationDesign and it’s the highest value-for-money around…

…if you would mind that, you wouldn’t still be using such an old MacBook… right 😉

enjoy !
