Using External monitor with DVI kills wireless connectivity

I recently purchased a BenQ G2400WD 24" 1920x1200 monitor, for use with my May 2007 GMA 950 2.0Ghz. Macbook.
Upon receiving the monitor, I immediately plugged it in to my Macbook, using the Mini-DV to VGA adaptor I already had, for use with projectors. The monitor was good, but a bit blurry and not too sharp, due to the analog signal. So I ordered a Mini-DVI to DVI adaptor. When it arrived, the improved picture quality was immediately apparent.
However, as time went on, I noticed my wireless connectivity was getting terrible. Extremely slow Safari page load times, and upon going to Terminal and pinging my router, I would often get response times of 21000 milliseconds, or worse! I did a lot of research, on router firmware, on wireless connectivity, etc., but to no prevail. Then, on a whim, while continually pinging my router, I removed the DVI adaptor from my monitor. The ping instantly dropped from tens of full seconds to just a stable 0.4 milliseconds! Using my VGA connection resulted in no worse wireless connectivity than without it, but upon plugging in DVI and stressing the connection a bit (i.e. downloading a large file), the connection went bonkers. The pings also immediately jump from 0.4 milliseconds to a range of 1-4 milliseconds, regardless of any "stressing".
I have done numerous research, including searching both here and on other discussion forums. It appears this problem with DVI connection is fairly common, but with no resolution so far. Any help would be great!
A few important notes:
-Both ends of both my VGA cable and my DVI cable are shielded.
-I have tried numerous channel changes of my router, to no prevail.
-While using DVI, EVERYTHING works well except the wireless. So the monitor isn't too demanding for my computer.
And I hope my thorough post didn't scare you away!

I have this same issue with the dvi and wireless disconnect. I am using a samsung 214T. I am glad to know i am not the only one seeing this, because it is kind of one of those things that is hard to believe. Anyway, I am also curious what kind of routers people have who are experiencing this issue. I am using a wrt54GL with tomato firmware.
Also, In addition to the disconnect, my picture quality on my monitor gradually degrades over time...starting with what looks like snow flecks. After waking from screen saver, sometimes it is full static. Turning off and turning back on the monitor clears the static away.
I can use another samsung 19in monitor with dvi without any problems.

Adjustment lag using external monitor with 4.3

I have an Eizo external monitor connected to my MBP and use the external for editing. I have been doing so for a couple years now and with all versions of Lightroom (even 4.2). I have always been able to see the changes/edits real-time on the external monitors when adjusting something with one of the LR sliders. Ever since I installed the latest LR update (4.3)- I don't see changes realtime. I have to wait until I let go of the mouse/slider to see the changes/adjustments. Anyone else having this issue? Is there something g I can do to fix it?

I believe that change was made in order to improve performance in the Develop module. If it's causing a problem in your workflow, you might like to report it here: Official Feature Request/Bug Report Forum

Using external monitor with 7"imac

in perusing this forum, to set up an external monitor, i only need a dvi adapter connected between the external monitor and the mini display port of the imac.
is that correct?
any suggestions on where to purchase the adapter?
once i have it connected, i believe i just need to go to system preferences and set it up via the display preferences.
thanks in advance.
mikeB.

i have a dell monitor also. 1901fp is the model number. it uses the dvi-d single link connector. i'm having problems finding a miniport to dvi-d single link connector. any suggestions?
or do i have to find an adapter to adapt the single link to dual link first?
i should have know this wasn't going to be easy!
thanks,

Using external monitor with macbook pro?

Can someone tell me how to get my Dell desktop monitor to work with my MBPro? I connected with usb/vga cable; i have a pic on the external monitor and the mouse pointer will move about the screen, but that's it; no funcitonality. I don't know what do do next? Settings?

It sounds like it's working perfectly, you have a functioning image and pointer. But you may be expecting to see some of your windows. It sounds like the monitor is connected in Extended Desktop mode, which means it's working as an additional area to your existing desktop, like sliding another table next to yours. So, if you want to see some windows and programs over on the new monitor, you should drag them there. Also, open your Displays system preference to see this and change settings.
If you expected to see the same image on both your monitors, you need to switch to Mirrored display. If there is a Displays icon on your menu bar, you can switch it there.

Using external monitor with powerbook G4 with a damaged display

Hi,
My powerbook's display has been seriously damaged from being banged from the outside. The screen now has a starburst and a series of heartbreaking lines that make it unusable. Because my budget really doesn't allow me to purchase a new computer right now, I am thinking about connecting it to an external monitor as a temporary fix. Is this a possibility for me? Would it have to be an apple monitor or can I just go ahead and get one of the cheapest ones that I can find? What equipment would I need? Is it possible to use the keyboard and mouse that are part of my laptop or do I need to have external ones? Thank you so much (I'm not exactly a computer genius, as you can tell)!

Lid Closed Mode: TiBooks supports "lid closed" (or clamshell) mode, which leaves the built-in display off and dedicates all video RAM to an external display. To used lid closed mode, your 'Book must be plugged into the AC adapter and connected to an external display and a USB mouse and keyboard (you might also want to consider external speakers). Power up your 'Book until the desktop appears on the external display and then close the lid. Your 'Book will go to sleep, but you can wake it by moving the mouse or using the keyboard. The built-in display will remain off, and the external monitor will become your only display. Since all video RAM is now dedicated to the external monitor, you may have more colors available at higher resolutions. The TiBook is designed to run safely in closed lid mode, but if yours runs hot (perhaps due to overclocking or high ambient temperatures), you may want to open the lid when in lid closed mode: The screen will remain off and the computer will more readily vent heat from the CPU.
To resume use of the internal display, you need to disconnect the external display, put the computer to sleep, and then open the lid. This will wake up your 'Book and restore use of the built-in display.

Using external monitor with laptop

At work I have an external monitor, keyboard and mouse so I want to close my laptop and leave it on a shelf while I work. Yesterday I plugged in my monitor before opening my laptop and it woke out of sleep (still closed) and let me work without having to open the machine. It also automatically fit my screen to the display size. Today I connected my laptop to the external monitor, but if I close it it goes to sleep (regardless of using the keyboard etc). The screen also shows a widescreen view of my desktop (it's not fit properly like yesterday). What do I have to do so that I can close my laptop, yet still be able to use it?

Today I connected my laptop to the external monitor, but if I close it it goes to sleep (regardless of using the keyboard etc).
That's normal. It will go to sleep, and you then wake it back up from the external keyboard/mouse. There are hacks such as Insomnia X which, I believe, will disable this sleep when the lid is closed, but you use any such hack at your own risk.
The screen also shows a widescreen view of my desktop (it's not fit properly like yesterday).
Have you checked the Displays preference for the external monitor to be sure it's set appropriately for the display's resolution?

Using external monitor with a bad logic board???

Can you use an external monitor on your ibook, if you have a bad logic board, to use it? Or is the only solution to use the shim, or get it fixed. Thanks.

Hi, and welcome to Apple Discussions.
If the graphics chip on the logic board has come loose, it won't drive the graphics to an external display, either. Sorry.

Can't sign in on external monitor with MBP after Yosemite upgrade

After Yosemite upgrade, when I turn on my MBP, I can't sign in using external monitor with MBP, always could before Yosemite. Blurred image of my wallpaper shows on monitor, can move arrow on external screen but sign-in only shows up on my computer screen, with no arrow. Since there is no arrow on the computer screen, and no sign in box on the external monitor, I have to unplug the external video to sign in on the computer, then plug in the monitor again. Any ideas?

NOWEK,
Thanks for this suggestion, but so far no joy. I have zapped the PRAM, jammed the Frabitz and smashed the Gafrogsnicker, all to no avail. When the MBP restarts I get a blurred image (extreme "vibrancy") on the external monitor, but no images of the login accounts to choose from or the other options. However, on the MBP screen I get all that. The keyboard and mouse respond, but just doesn't display on the external monitor. This is of interest to me because I have the MBP down in a credenza with other related gear and the external monitor and keyboard up on my desk. It's true I don't have to do this often, but still, it just started this aggravation with Yosemite. Thanks for trying to help.

Is there anyway to have an 11 inch mac air connected to an external monitor with lid closed and still be able to see content. I have a wireless ketboard and mouse and have tried everything. Only works when plugged in.

You are referring to a feature called Clamshell Mode, please read Clamshell Mode setup for instructions.
BTW when posting when you use generalities such as "have tried everything" this tells us nothing. When posting please be specific and try to paint a complete picture. It just makes things easier for those trying to help you.

How do i run an external monitor with my macbook and change settings so that when i close the lid the signal to the monitor is not lost and i can continue using the mac with a mouse and a wireless keyboard?

No, nothing will prevent the computer from going to sleep when you close its display except third-party hacks that are designed to do exactly that. I strongly advise against using any of those, as they may interfere with successful entry into clamshell mode (and they carry other downside risks as well). Just wait until the computer is asleep (with its sleep light pulsing), then press any key on the keyboard. It sounds as though your setup is working as it's designed to do.

Connect 2 externa monitors with different resolutions?

Is it possible to oonnect 2 external monitors, with different resolutions to a mbp pro?
I've read some about the "matrox solution", but that one requires that the monitors uses the same resolution.
And, just to be clear, I don't want to just duplicate the screens, one should be primary.

You may want to phone OWC and ask whether what you want to do is possible if one monitor is connected to the mini-Displayport and the other is connected to a USB port using this adapter:
http://eshop.macsales.com/item/Other%20World%20Computing/VIDU2DVIA/
Note that the OWC adapter, like most USB video adapters I've seen advertised, is limited to a maximum resolution of 1600 x 1200, so you won't want to use it with a monitor whose native resolution is higher than that.

Connecting a regular Monitor with DVI

I'm wondering if I can connect a pc-monitor to the apple TV using a HDMI-DVI cable?
Instead of using a TV I want to use a pc-monitor with DVI input.
Is this possible or do I have to connect really a TV?

Welcome to the  Discussion Forums.
There would be a couple of issues to overcome. One is already mentioned by JG, HDCP is often not supported by DVI, you would need to check. Then there's a resolution issue the GPU of the tv may not support the native resolution of a large monitor, also your picture may or may not fill the screen and WS tv is 16:9, WS monitors are typically 16:10. Finally DVI doesn't carry audio so you would need to take care of audio in another way.
It's not impossible, there are those that use them with the tv, but you would need to check your particular monitor would work.

Connecting Dynadock to a second external monitor with a splitter

Hey guys -
I have a Samsung Series 9 which I have connected to the Dynadock3.0. I have two additional external monitors which I wanted to connect via the dynadock. I used a vga splitter to connect to the two monitors (dell u2312hm) via vga cables and then used the vga-to-dvi converter to connect to the Dynadock. Unfortunately the computer only recognizes both the external monitors as one screen and while I am able to extend between my laptop screen and the external monitors, both the external monitors duplicate the same screen.
Help!

Any help here would be greatly appreciated

How do I use two external monitors with my laptop?

I have a new Pavilion dm4-301 d cl Entertainment PC. My OS is Windows 7. I am used to using two external monitors with a docking station. This new laptop does not have a docking station. What do I need to get to use two external monitors?
This question was solved.
View Solution.

Certainly not without a dock but even with, HP laptop docks pretty well limit you to one of the external monitor ports, even if there are two on the dock. We have used a device called an Atlona AT-HDPIX2 which is a usb to hdmi adapter. It provides a third monitor capability for a laptop....use the native external monitor port and the internal laptop display and then this device gives a third monitor which is full configurable from the Windows 7 display interface...clone, extend, etc. It allows full HD resolution and is responsive enough for even light gaming. HP makes no true docking station for your laptop.
