Using cinema monitor with top closed

A MBP C2D is driving a 30 inch Apple HD cinema monitor with the top closed.
USB KB and mouse connected to the MBP. OS 10.4.9.
Can use the power button on the display to switch from sleep (MBP sleep light pulses) to normal operation (sleep light steady on at medium). Sleep light behavior is not discussed in the MBP User Guide when using these conditions.
Can see no indication the MBP display is on.
So is this all normal behavior? And the best way to undertake daily operation when want only the 30 inch monitor as my display.
?

Personally, I would leave the screen lid cracked open a bit for cooling purposes. Air is drawn in through the keyboard to aid in cooling.

Can I use another monitor with my iMac desk top?

Can I use another monitor with my iMac desk top? Our monitor screen is going out and would like to have another option then replacing the whole thing! I think A LCD TV would be less expensive than the repairs to our iMac.( OS 10.6.8 )

Yes, but we need to know exactly which year model you have? So that we can advise you on exactly which adapter you need for you iMac.
see > How to identify iMac models
Plus, adding that Computer Monitors make better displays than TVs and comparatively cost a little less than TVs.
For examples of monitors that have both DVI and VGA inputs:

Audio & video via HDMI to an external monitor with lid closed.

I would like to run a Macbook Pro Retina (2014) with the lid closed and all video and audio via HDMI routed to an external monitor (Samsung Syncmaster from 2010). Is this possible? When I try this, no sound is transferred to the external monitor and I cannot operate the Macbook Pro with the lid closed. As soon as I close the lid, it cuts the signal to the external screen.
I’ve tried looking for previous posts but they’re about MCP’s connecting via Thunderbolt or DVI. Any ideas?

Seems like there may be two separate questions here. Audio working in either configuration and video from HDMI when lid closed. First, you are doing this with the Mac running off of AC, not battery, right?
Audio:
Is the HCMI cable you are using able to carry the audio? Some cables don't.
The only way I've ever used external displays with lid closed is with the thunder port (or DVI) adapter, not with the HDMI. I see the specs from Apple:
HDMI video output
Support for 1080p resolution at up to 60Hz
Support for 3840-by-2160 resolution at 30Hz
Support for 4096-by-2160 resolution at 24Hz
So have you tried varying the screen res to determine the results? I can find no specs regarding what ports remain operational in clamshell. Like you, I would have assumed all of them.
I suspect only the thunderbolt port would support your desired config -- try a thunderbolt/hdmi adapter.
Finally, clamshell mode doesn't allow the MBP to cool efficiently. Heat kills electronics, so if it's too warm or the fans really kick in, you might want to reconsider this setup.

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.

System hangs after using external display with lid closed

I often use my MBP with the lid closed with an external display and Bluetooth mouse and keyboard. When done in this mode, I put the system to sleep using the apple menu, then disconnect the monitor. I found some info on the apple site explaining that this was the recommended procedure for exiting the lid-closed mode.
However, sometimes the system doesn't go to sleep. Opening the lid, the LED goes out, but the display remains off. If I then try reconnecting the external monitor, nothing happens. It appears that it has gone into some mode where it is active, but no displays are enabled. My only resource at this point is to power the system off and back on, at which point everything is ok.
I'm wondering if turning off my bluetooth devices after selecting the sleep menu item is causing the system to reawaken at a bad time, causing this state to occur.
I have also run into problems when connecting an external projection monitor. On several occassions I have connected the external display adapter before turning on the projector, or before connecting it to the adapter, and the system locked-up hard (no mouse movement, etc). My only recourse was hard power off.
Any ideas? Is this a broken system or are these known OSX or MBP issues?

Problem using dual monitors with Radeon 9000 Pro and 2 x Samsung SM223BW

Hello all
I really need an expert opinion here:
I am using quite a lot my MDD 1.25Ghz that is still equipped with the OEM ATI 9000 Pro Mac Edition with 64MBs of Video RAM and as most if not all Mac-specific cards it has an ADC and a DVI port. I recently purchased a couple of Samsung monitors; the afore mention in the subject SM223BW. The monitors have two inputs, both DVI and D-SUB (Analog VGA or otherwise plain old RGB).
I have purchased a Formac ADC to DVI converter and connected this output to the DVI input of the first monitor. It works like a charm and the picture quality it is quite good (not as with an Apple Display but I couldn't afford them at this stage). For the second monitor I used a DVI to VGA cable (going from the DVI output of the card to the VGA In of the monitor).
Now here is the problem: The monitor that is connected ADC to DVI has all the available 16:10 ratio option that are suitable for this monitor. The DVI to VGA one gives me only a 1680x1050 and all the rest are 4x3 resolutions.
Would anyone know why this happens? Could it be a monitor issue? Could it be that perhaps TFT monitors offer different resolutions according to the input used. Or could it be the graphics card? Or even perhaps the cable?
Under OS X, same settings and same computer I am given more resolution options. Would that mean that it might be as well my beloved OS 9 in combination with the card?
Or am I stressing this too far?
Please any ideas are more than welcome
PS: I have a dual 2.0Ghz G5 connected to the rest of the DVI and VGA inputs to be able to run both without having to repatch. Otherwise a DVI to DVI connection would have made more sense and solved the problem

Hey Simon
I bought these monitors for their dual input functionality. The reason that I have the G4 connected to VGA is because I have another G5 connected the other way around in order to be able to use both computers, at any given time, with two screens.
Perhaps to make clear the connections I've done (if of course anyone is interested :)) ...
The G4 connects via ADC to DVI to the DVI input of Monitor No.1
The G5 connects via VGA to VGA to Monitor No.1
The G4 connects via DVI to VGA to Monitor No.2
The G5 connects via DVI to DVI to Monitor No.2
Another question would be why simply one mac isn't connected solely via DVI and the other one via VGA? The reason is that the VGA input looks awful on these screens for whatever reason. The image is seriously not sharp, the fonts looks horrendous and even with a lot of tweaking from the monitor settings, still I'd say the image is minging. If anyone knows why a VGA input can look that bad and still a monitor being in the market please let me know. It could be that this monitor is aimed to PC users and with the accompanying PC-only drivers all such are non-existent...Anyway I decided to go with the half DVI-half VGA solution to get the best out of the situation.
But on the question asked, I decided to use a 2 DVI input Avocent KVM that I've got with interesting results. I am pretty sure it is boring to read but if anyone has spare time here it goes:
The G4 connects via ADC to DVI to Monitor 1.
Monitor 2 DVI output connects to DVI KVM Input
The G4 connects via DVI to DVI to KVM Output 1
The G5 connects via DVI to DVI to KVM Output 2
The G5 still connects via VGA to VGA to Monitor 2
In this manner I am guaranteed to utilize the DVI inputs for both monitors, at least on my G4 and the G5 be forced to utilize one VGA. The plus side of the situation is that I can use both systems with the flick of a button without having to get up to change the Source on the monitors plus of course one keyboard and a mouse. Now here is the interesting bit:
Under OS 9, with the resolution 1280x800 on Monitor No.1 (the one connected via ADC to DVI) flips to - I think - 1680x1050 - it could be higher than that - with a thick black frame around the Desktop occupying a good chunk of the screen and the actual OS 9 looking minuscule at the center of it.
Monitor No.2 (the DVI to DVI connected one) looks just fine.
Now on top of that, when the G5 is switched on but the KVM is outputting the G4 desktop on Monitor No.2, whenever the mouse cursor slides on this monitor, it goes black! Just simply black and when I move the mouse cursor back on Monitor No.1 goes Desktop again.
Under OS X, none of the afore mentioned problems exist. Everything runs fine and I am give more 16:10 resolutions as well.
Confused? I am

Running with top closed

I use my MacBook as an Mp3 player in my car as do several of my friends. To accomplish this I plug an FM radio adapter in the headphone jack and play the audio through the FM radio in the car. This works quite well except it would be nice if I could close the display panel and continue operating with the remote control. I understand that this can be accomplished if there is an external video display plugged in but it would be nice if I could run I-Tunes with the top closed and no video output. Does anyone know how this could be accomplished?

Officially you can't and shouldn't as your Macbook
could overheat and damage itself. Although there are
'hacks' that give you the option to do this...
I would not advise running it with the lid closed. Air is drawn in through the keyboard for cooling.

I have a Samsung Laptop but would like to use Cinema Display with mini displayport. Is that possible?

I have a Samsung Lap top but would like to use Cinema Display. The only connections on my lap top is HDMI and VGA. How can I get it to work?

Thanks Malcolm. I saw this on the apple site
Kanex C247D Single-Link DVI to Mini DisplayPort Converter
Will that work?
I also spoke to someone at apple..They told me to get 2 cables. Mini DisplayPort to Dvi and Dvi to Hdmi..Connect the 2 and it will work...Do you think it will work? Just to save$$$

Using ADC Monitor with the new Mac Mini

My husband has an Apple monitor with an ADC connection. I would like to purchase the new Mac Mini, but would like to use his current monitor. I know there is an ADC to DVI adapter, but the new Mac Mini uses the Mini Display...could I use yet another adapter? I am trying to save money, but don't want to the display quality to be really poor. Space is not an issue. Any help would be greatly appreciated.

I have located that, but my concern is the DVI connection to the Mini Display connection on the Mac Mini. My understanding is that they are different.

How to use two monitors with my Mac mini

Hello,
I have a Mac mini and using a 20" Samsung Monitor with it which works well. I also have my 40" LCD Samsung telly, set up next to it. Whenever i watch a DVD using my Mac i have to swap over the cables. Is there a way of getting the right cables etc and making it so i would be able to watch a dvd on the 40" and still use the 20" surfing the net etc. I had a similar set up with my old windows laptop, but cant seem to work out how do it with the mac. Both monitors have modern sockets, the 40in has HDMI/DVI IN and AGV, the 20" has AGV and HDCP/DVI IN. Many thanks.

To the best of my knowledge there is no way to use dual displays on the Mini. You may be able to find some adapter that will allow you to physically connect two displays, but they will be mirrored, not spanned.
To do what you describe would take spanning, which the Mini is not capable of doing. Unless something has changed recently,..

How to use one monitor with two Power Macs

I searched this forum and was unable to find an answer. Although I believe it's probably here.
Nevertheless, I have a Power Mac G5 and a rarely used Power Mac G3. I'd like to share the G5's VGA Accusync 120 CRT monitor with the G3. I know there is a way to switch the monitor between computers without pulling plugs in and out of the machines.
Does anyone have any specific switch I could buy to solve this issue. I don't care so much for picture quality for the G3. But I don't want to compromise picture quality for the G5.

You're looking for what's called a KVM (Keyboard, Video, Mouse) switch.
This one should do what you're looking for. I've not used it, but it does VGA switching like you want and is inexpensive.
