MacBook :: WiFi Slowdown When Connected To TV (No External Monitor)

Sep 28, 2009

I have a strange problem with a WiFi slowdown when connected to a TV. Here are the specs of the equipment:
2.2 Ghz white macbook, santa rosa, 4 gb ram, purchased January 2008
Panasonic TV connected via HDMI to DVI cable + Apple Mini DVI to DVI connector
USB Western Digital harddrive connected to a 500 GB Time Capsule (1st edition, no dual channels)
Snow leopard 10.6.1

Before upgrading to snow leopard, I would frequently use the macbook to provide video to the above mentioned TV streamed from a hard drive connected to an imac (connected to the same time capsule). I moved, and upgraded to snow leopard, and haven't tried this until finished setting up my equipment yesterday. I can stream videos to the macbook from this hard drive fine when nothing is connected. However, the moment I plug in the mini-DVI connector, the WiFi drops to a crawl. This applies not only the to air disk but any data from the network (internet, etc.)

A couple of additional notes: Display is set to mirror. Has nothing to do with clamshell mode because the macbook isn't closed. Nothing to do with location/interference- the effect is instantaneous with plugging and unplugging the cable. The base station is actually closer than in my previous setup and is pretty much 20 feet away in direct line of sight. I connect to another external monitor daily at work (vga, again with apple mini dvi to vga adapter)- no issue whatsoever restart did not help. I canceled all time machine backups over the network to limit that as a factor- no effect.

MacBook Pro :: Slow WiFi On Mid-2010 MBP - Signal Says Its Full Connected?

Sep 22, 2010

I have had my 15" i7 MBP for around a week now, and a handful of times (3 times last night) it just decided it doesnt want to connect to the internet.The WiFi Signal still says its connected full, and other laptops don't have an issue (not even my old 13" MacBook).I have tried changing the DNS to OpenDns and to Google's DNS but with no luck. The problem is intermittent, and it will be fine for a day, then it will just decide it doesn't want to work.

MacBook Pro :: How To Turn Off The Builtin Display When Connected To An External Monitor

Nov 21, 2010

WITHOUT closing the lid, because i like using the touchpad. i know that you can turn the brightness all the way down, but sometimes windows from the main screen randomly open on the other display. and it also slows down performance. i want to turn off the 13" screen as if the lid was closed. that way, the mac doesn't even see it.

MacBook :: Unibody Display - Connected To External Monitor - Black Screen

May 7, 2010

Well my unibody macbook display decided to screw up last night, it was working fine last night no problem. Connected to a external monitor. I fell asleep last night with front row left on, obviously it went to sleep and then I woke up and the screen was black. Now the LED lights are working, my external display is also working. The display settings recognize a screen being present (when I click detect displays and gather windows - 2 windows appear). Ive reset PRAM, SMC, reseated the RAM, control+shift+eject (which just made the screen flicker a little after turning it back on) and Im out of ideas. Its out of warranty and about about 18months old.

MacBook :: Can't View The Entire Screen When Connected To An External Monitor Via VGA Adapter

May 29, 2012

my screen cracked on my MacBook and I'm unable to see anything (it's just fuzzy white) so I purchased the VGA adaptor so I can connect to an external monitor.  When I plug in the screen is zoomed to close and I can not view the entire screen.  I can see one application that I have open, which is iMovie but can not see the top menu or my icons at the bottom.  How can I adjust the settings seeing how I can not access the menu bar or anything else for that matter.  It also appears to be showing a second screen, maybe not my desktop because the background is different.  I'm running on OS X Lion.   

I'm trying to finish an end of the year slide show for my kindergartner that I need completed today, I was five minutes away from finalizing then my two year old threw his monster truck at my screen!

MacBook :: High Frequency Ringing Sound When Both External Monitor & Speakers Are Connected?

Jan 8, 2009

I searched the archives and I can't believe no one has mentioned this yet! This is a huge problem on both my Rev A and my new Rev B. When you connect an external monitor and external speakers using the headphone output, there is a high frequency ringing sound coming out of the speakers. I've managed to live with it by turning the treble to minimum and keeping the volume low enough but at the expense of sound quality. The strange part is, if you disconnect the monitor, the ringing sound stops. The problem only occurs if you have speakers and monitor plugged in at the same time. I've tried this on my Samsung monitor, my SONY TV, and my Panasonic audio receiver. The problem occurs with both Rev A and Rev B while my white MacBook and 2007 MacBook Pro all sound fine.

MacBook Air :: Doesn't Detect External Monitor Connected Through Mini Display Port To HDMI Adapter

Sep 8, 2014

I bought a MBA 13" last month and now I'm trying to connect an external monitor through a Mini Display Port-to-HDMI adapter and most of the times the display shows a message "No signal detected"...

I've tried all the possible combinations between the MAC and the Monitor but it would seem a random matter.

OS X :: How To Disable Connected External Monitor

Jan 17, 2007

Is there an easy way to cause a connected external monitor to be "disabled?" E.G. I have an iMac connected to an LCD TV (via VGA, spanned, external at 1360x768). If the TV is plugged in, even if it's off, the computer switches to spanning mode. The consequence of this is that, if my preferred setup is to have the external be main, for instance, I essentially have to unplug it from the iMac whenever I don't want to be using it. Even if the external is the 2ary dsplay, it means that the mouse can go off the edge of the screen on one side, and that two of the hot corners are messed up. Is there any utility that could do something like add a "disable external display" item to preferences or the menu bar?

MacBook Air :: Running An External Monitor, It Slow Down The Speed Of MBA?

Jan 16, 2008

Since it has built in graphics, will running a 23" ACD slow the rest of the computer? I'm thinking about Photoshop and Flash here. My work computer is a 15" MBP at 2.0 Ghz and I think a drop to 1.6 Ghz wouldn't be so bad if I could use a separate monitor and not see anymore of a performance drop.

Applications :: Quicktime Plays When External Monitor Connected

May 16, 2010

Recently, my quicktime (with Perian installed) stopped playing AVI files - giving me the whole 'The movie is in a format Quicktime doesn't understand' business. This made no sense to me as AVIs were playing fine previously. Nothing I did could fix the problem. HOWEVER, just today I plugged in an external monitor to test something out; lo and behold, quicktime is playing AVI files just fine again. What's going on?! Has anyone seen this behaviour before?

IMac :: Use Dell Monitor As Primary Monitor Connected?

Oct 22, 2009

I was surprised one day to find an inch of white line running from top to bottom on my screen. Then after a week it expanded to two inches white line, then suddenly it turned all black and I can't see two inches of my screen from the right edge. I was reading some forums and found out that I can use a dell monitor as a secondary monitor, but is it possible to use the dell monitor as the primary monitor in case the black line will spread throughout the entire iMac screen? so the iMac would serve as a stand alone processor like a regular desktop?

MacBook Pro :: Unable To Get Internet / Saying Connected To WiFi

Nov 21, 2009

I have a MacBook pro that I'm having issues with. It connects to my home Wi-Fi (the n version of the Apple Airport Base Station) and I get a strong signal but whether I use Firefox or any other web browser or internet based program I get a message that I'm not connected to the internet. I can even select network diagnostics and it walks me through steps where I choose my network, reset my cable modem, base station, etc. and at the end it says it is unable to fix the problem. i have a 2nd MBP that I use on the same network with no issues at all. This issue started showing up about a month ago but did not happen often. Most of the time it happened when I had shut my MBP down since I had to go take it with me to meetings. Often after removing the battery for a minute I could boot up and it would work but now no matter what I do it won't work.
