• Refresh rate of the external monitor (closed macbook) reset

  Hello

  Im very new to OS X, I have a macbook air 13 "that I have it plugged into my external monitor acer, when he was in closed mode (clamshell) I changed frequency by accident and now I can't change this back as the ' entry is not displayed. How can I change the refresh rate of the external monitor when the settings show only if the macbook is closed? As I said, I'm new so I am not very confident through many parameters, any help is appreciated.

  If you have previously enabled "Screen sharing" Preferences-> sharing system then you can use another Mac to control this Mac and change it to one that works remotely.

  You could 'open' the Mac to use its built-in screen and then be able to change the settings of the external monitor.

  You can try to reset the setting by following the steps listed here Re: how to restore the display settings

• External monitor flickers and send the display to the laptop screen

  I'm running Windows 7 on a ThinkPad. I have an external monitor from ViewSonic VX2433wm I connect and use scope display mode. This all worked fine for many months, and then a few months ago I started having a problem where, after several minutes, the ViewSonic and the computer screen will be time twinkle a few times and then just what is on the ViewSonic flies to the computer screen. I have updated the monitor display drivers and the laptop, but still have the problem. In addition, I discovered by chance yesterday that, even if the external monitor is turned off but connected to the laptop, the screen of the computer, still wobbles. It's driving me crazy!

  Hello

  I suggest you try the following steps:

  Step 1: change display settings also change color depth then test

• External monitor flickers always on Satellite Pro U400 - 13G

  Hello

  I have a Satellite Pro U400 - 13G that connects external monitors with VGA port.

  I am running Vista Ultimate 64-bit with the latest graphics drivers from intel, I also tried the drivers from the Toshiba download site.

  Anyway... I tried 3 different external screens to connect a LG with resolution 1280 x 1024, an acer projector with resolution 1024 x 768 and a Samsung SyncMaster 226BW running 1680 x 1050.

  All these monitors simply sparkles... a higher resolution = more flicker. It seems to be worse with gray background.

  I tried the system Windows 7 RC1, same problem.

  When I unplug my diet, Twinkle seems to be... a little reduced, there is still a lot of flicker.

  Someone knows how to fix this?

  Hello

  I think she might be grounded question in this case it is recommended to use a power adapter 2 cords.

  I also found this thread on U400:

• Satellite A100-784 - external monitor flickers with AC adapter

  Hello

  I have problem with external monitor on Toshiba Satellite A100-784.

  _Problem 1: _
  External monitor blinks as a flag up and down when the adapter is connected to the laptop.
  What laptop works on this medication batery is ok. What is the problem of my od my laptop power adapter (graphics card) od something else?

  _Problem 2: _
  When I use samsung 22 "on batery then monitor does not Flash as a flag but pixels moves randomly left or right. I try to find new drivers for my graphics 945GM card, but on the toshiba support page there is an old drivers which was already instaled on my laptop.

  So, if you have any suggestions for me for problem 1 or 2 Please help a cant use my monitors :(

  PS Can use drivers from Intel official Page for graphics card?
  If I can't then I contact toshiba support team to release new drivers :).

  Thank you all.

  Hello!

  For your first problem, I think that the AC/DC adapter is faulty or it s a motherboard problem.
  This should be checked by a technician for laptop.
  I put t know what OS you use, but you can try to use the driver from the Intel Web site.
  There should be a more recent version available:

• Tecra M5: External monitor flickers - grounded question?

  Hello

  I just bought a new Acer Full HD LCD Monitor (P244W) and have tried to connect on my Tecra M5 VGA port.
  It works, but there is a noticeable and more annoying flicker. I tried with XP (SP3) and now Vista (SP1) and it happens for both. I have the latest BIOS and NVidia drivers. The actual laptop LCD screen still works fine, it's just the external screen that flickers.

  To make sure that there is nothing wrong with the monitor, I plugged the ATI video card VGA port on my desktop pc and it displays fine without flickering.

  After completing the web for people with similar problems, I narrowed down it to her being caused by my power adapter with a grounding problem as the flicker disappears as soon as I unplug the AC adapter and just run the battery. It seems the solutons common to this problem are:

  (1) try some different VGA cables with better shielding against interference.
  I tried this and it made no difference. I tried cables with or without the magnet ferrite/Starter thing at both ends of the cable and the flicker remained.

  (2) try the different screen resolutions and refresh rate.
  Tried to adjust some lower resolutions, but the twinkle remained (not to mention that I prefer to keep the native resolution of 1920 x 1080 for my monitor). The NVidia driver allows only 60 Hz refresh rate at 1920 x 1080, so I couldn't change that.

  (3) make sure that the computer laptop AC adapter / CC and the monitor are connected to the same wall jack and are on the same power expansion card.
  Tried, but it does not solve.

  (4) run an extension cord to another circuit of power supply in my house and to the AC adapter and the monitor of this to see if its something wrong with the wall socket using im.
  I tried connecting to a wall in my laundry, but does not resolve it.

  (5) try using a different power expansion card and nothing else is connected on the power adapter and the monitor.
  Tried, but it does not solve.

  (6) get a pin 3 to 2-prong adapter, so the power adapter is connected to the Earth is no longer.
  Most of the people on the web seem to say this corrects the problem, but I don't know how it is safe to leave this way long term. Especially, when stories of mobile phones capture the fire are multiplying.

  (7) get an adapter to generic brand as they sometimes solve the problem better than the Toshiba power adapter grounding.
  Yet once again, I would avoid this option rather than even the most generic brands cost dear.

  (8) remove the battery and run its own from the AC adapter.
  Tried, but it does not solve.

  9) play with the settings of monitors.
  Tried, but none of the settings fixed it.

  So, what are my options?
  Is there a known cause and the solution to this problem?
  If my laptop is still under warranty, can I get a replacement AC adapter / CC or something to work around this problem?

  Thank you

• Tecra S11 - 11G - external monitor flickers when the Wifi is enabled

  I have a similar problem on my brand new Tecra S11 - 11G. The only difference is that the problem is present only when I have my laptop plugged in and turned on WiFi radio.

  If I turn the Wifi radio off and keep the laptop connected to the power source, the external screen keeps flickering. If I keep the WiFi radio and disconnect it from the power source blinking stops, too.

  I reported this problem to Toshiba customer to the Portugal (where I bought it) and they gave me the ticket case #710008193. They said that they would not replace the defective unit and that I should leave for repair. It is absolutely amazing because the laptop is brand new. A customer still expects to have a well work product when needed out of the box without having to call the repair man. I think it is their obligation to replace the damaged aircraft. In addition, this laptop is part of a fleet of the company who buys only Toshiba laptops and we are talking about a Tecra and not a Satellite. We deserve more respect from Toshiba.

  In a year or two, I have a new laptop (company policy) and it surely won't be a Toshiba.

  > They said they would not replace the defective unit and that I should leave for repair. It is absolutely amazing because the laptop is brand new

  That is why amazing? A hardware malfunction can still happen and this happens not only in the world of the computer/laptop. Therefore, manufacturers provide a service to a client and failure may be fixed and covered by the warranty.

  > A customer still waiting to have a well work product when needed out of the box without having to call the repair man. I think it is their obligation to replace the damaged aircraft

  Of course you are right, but in the reality of things happening.
  My PS3 died after a short period of time. It has been fixed and replaced under warranty conditions, but this isn't a reason for me to say; I would not buy PS3 more because of this problem.
  My BMW had some engine problems, that it was fixed under warranty and I would buy this car again once because this car is great and I think other builders are no better, and I think this would also happen to other manufacturers

  That s my personal opinion in the opinion

• external monitor display resolution not as an option

  I try to have an external monitor for MacBook Pro (the Captain). While setting up, I couldn't find the proper resolution (1920 * 1080 @60 Hz) in the display settings. I did a nd restart read a lot about this, but I couldn't find a simple solution on how to add a resolution in the option if it is not found.

  hope you can help me configure the resolution to the required resolution.

• MacBook Pro retina 15 inch heats up when it is connected to the external monitor

  Hello

  My problem: When I connect my monitor (LG IPS277L) temperature of my Macbook Pro starts to heat upward. This problem often occurs when I use Facetime.

  I found it really strange because I should have a pretty good Macbook Pro for this.

  MacBook Pro (15 inch, retina, medio 2015)

  Processor: 2.5 GHz Intel Core i7

  Memory: 16 GB 1600 MHz DDR3

  Graphics card: Iris Pro 1536 MB Intel / AMD Radeon R9 M370X

  El Captain 10.11.6 OSX

  I hope that someone recognizes this problem and wants to share their solution.

  When you connect to an external monitor, you use the AMD Chip for graphics (without the external screen, most of the software needs only the graphics engine Intel).  It attracts more power and therefore heats up.  All MacBook Pro for this to some extent.  This should be considered normal.  If the computer is actually overheating, it will stop.

• Can I connect Macbook Air to two external monitors?

• MacBook 12 "and external monitors - experiences

  That I have not found much info on using a MacBook 12 "with external monitors (but have found problems), I thought I would post my experiences here for the benefit of other researchers:

  MacBook 12 "with Dell u3415w (3440 x 1440) via a USB - C adapter Digital AV Multiport (HDMI):

  VIDEO: Experienced random black screens on the external monitor. After update to El Capitan 10.11.4 version which included an update of the firmware of the adapter, the problem become constant, with the external screen crashing to black seconds nonstop. Switching the HDMI on the MHL port on the monitor completely solved this problem.

  VIDEO: I'm only able to get a resolution of 2560 x 1080 scaling to fill the screen, which is a little fuzzy but fine for office tasks - selection reduced 3440 x 1440 or "best resolution for this monitor" translates into a look, windowed 16:9, with black bars on the right and left. I have not yet found solution to reach ultra-wide 21:9 angle at the native resolution (but would appreciate a).

  VIDEO: Macbook 12 discs easily display 3440 x 1440 for tasks of office such as word processing and surfing. Video full HD YouTube is generally good, but gets now and then a little agitated.

  AUDIO: Holding Option and clicking on the speaker icon in the menu bar show selectable option for the audio output to the device (monitor). On this screen, it seems to be a problem of reception of the signal of the Macbook when another device is connected to another port. In my case, a PC connected to the DisplayPort would be "laundered" the audio signal of Mac but ONLY if the PC has been out audio through external speakers, not the monitor (a lot of trial and error to discover this. When the audio PC sent ONLY to the screen, the monitor then accept the audio signal of the Mac, too. But have an external speaker connected via a cable audio 3.5 mm to the pc mobo (taken minijack) would somehow replace the TWO PC and Mac audio signal to the monitor. Something to do through the DP connection maybe)

  with ASUS PB27Q (2560 x 1440) via an adapter, no problem.

  with ASUS PA328Q more ASUS PB287Q (3840 x 2160 or '4 K') using the same adapter. Cursor extremely lag/Office up to that you enable DP (Displayport) 1.2 through settings on the screen of the monitors. This allows the Macbook to drive a monitor 4K at 30 Hz, which is always a little laggy, but realistic enough to be productive for word processing, surfing, etc. Would not recommend a 4K monitor for Macbook 12 for a really "nice" experience until / unless that 60 Hz is an option.

  Hope someone finds this is useful.

• MacBook pro at 1920px external monitor via hdmi?

  I just got MacBook pro 13-inch retina and the default resolution is 1280px in width, and the maximum value is 1600px.

  If I connect the laptop to an external monitor via HMDI 1920px resolution, the resolution will actually be 1920, max mobile as 1600?

  You can set the external display to the monitor native resolution or HDMI resolution according to your preference.

  Don't use mirror display on external monitor because when you mirror on the screen display resolution is also in reverse. Use extended display mode.

• Portege R600-13Z - flickering picture on external monitor

  Hi support them!

  I own an ASUS VW224 VGA monitor and a Portege R600 13Z. Is the native resolution of 1680 x 1050 and directly on VGA cable (do not know if there is a docking station). GPU driver date is 31.03.2010 version 8.15.10.2104 (newest I think).

  The problem is that the screen is blinking. The darker the area displayed the strongest flicker is perceived. It's a "horizontal flicker", like the horizontal lines are pursuing each other up and down the screen. It is very annoying.

  Since the laptop screen itself or the monitor with another computer ASUS show any flickers, I think that the problem is rooted in the described configuration interaction. I can set different settings on the monitor itself. Related to the problem could be 50 and 54 of Phase clock.

  Windows tells me in config monitor refresh rate is 60. However, refresh rates and clock can be set to the same without change.

  The meaning of phase I don't know.
  Any ideas to solve the problem?

  See you soon!

  I think that it comes to the grounding of s.
  Please check if the flicker would be available using the battery power.

  I've been reading about such symptoms on external monitors.
  In most cases the use of the power supply cable 3 cord would solve this problem.

• Why I can't have a decent resolution of my Macbook Air with an external monitor?

  MacBook Air 13 "(early 2014)

  I bought a Samsung S32E590C 32 '' nice monitor but cannot get above 1920 x 1080 @ 60 Hz (1080 p) using Thunderbolt to HDMI. The resolution is so low that I can't use the screen correctly. I'm afraid I won't be able to get a better resolution with my Macbook Air and will have to sell the monitor...

  Suggestions please.

  Hi sansthwaites,

  Welcome to the communities of Apple Support! I'm sorry to hear you're having problems with your MacBook Air and your new view. I'm sure we can help you understand what can happen.

  Based on your model described, it seems that the beginning of 2014 MacBook Air should be able to produce a somewhat higher resolution for a monitor external, as shown here:

  Graphics and video Support

  • Intel HD 5000 graphics card
  • Dual display and copy video: simultaneous support for native resolution on the built-in display and up to 2560 by 1600 pixels on an external display, both at millions of colors

  MacBook Air (13 inches, beginning 2014) - technical specifications

  However, the max possible resolution may be limited by the type of connection, or the specific adapter you use. For example, this Mini-DisplayPort-HDMI adapter supports up to 4 K (~ 3840 x 2160) resolution:

  Belkin 4 K Mini DisplayPort to HDMI adapter - Apple

  .. supported .While this Mini-DisplayPort-HDMI adapter only supports 1920 x 1200:

  Amazon.com: AmazonBasics Mini (Thunderbolt) adapter DisplayPort to HDMI: computers & accessories

  Then how you connect to an external monitor can certainly affect the maximum resolution available. In this case especially, however, I suspect that the issue is actually the screen itself, as it appears from the Samsung S32E590C screen to list a 1920 x 1080 max resolution:

  Support - curved screens S32E590C | Monitors Samsung

  I hope that was helpful.

  See you soon
