New MacBook rocks and in cables to hook it up to my Sanyo HDTV 1080p. I plug in the HDMI cable and the picture comes on.
However, every once in awhile the screen goes black and it says "Signal Not Found." Also, every time I turn on the MacBook I have to unplug the HDMI cable, wait a few seconds, and then plug it back in before it will detect the external display.
I'm using a mini display-port to hdmi lead and it worked once. I unplugged the hdmi cable when it was still connected to the mac and now it wont find it.

I have a 2011 MBP (thunderbolt) that I've had for about a year now. I use it daily at work, with an external LCD monitor connected with a mini-dvi -> DVI, no problem, except for the occasional need to restart when first connected.
However, at home I have an AOC Razor 24" monitor that until recently was connected to my home PC via HDMI, working just fine. However, my PC died and now I would very much like to be able to use this monitor at home until such a time when I get around to finding a desktop replacement. My MacBook Pro, however, has completely different ideas it seems... It completely refuses to recognise the monitor. I don't get the blue "flash" and it doesn't show up int eh display panel at all, not "sleeping" or otherwise, it simply looks as if it's not there.
Having trawled the forums, I've done the Jan/Feb firmware update, I've tried two different HDMI converters (One the Moshi from my local Apple retailer, the other a no-name brand converter, which works fine elsewhere), I've even tried a mini-dvi -> DVI -> HDMI converter (I know, I didn't expect it to work, but when you're at then end of your wits, you're at the end of your wits ). I've gone through three HDMI cables and tried an assortment of "black magic" solutions found on the net, with the adapter half-way plugged in, resetting the PROM, closing/opening the lid, running gfxCardStatus ( just in case it did something ) and checking the monitor elsewhere.
The only thing I haven't done (that I can think of) is swap the actual MBP,however, as mentioned, I use an external DVI monitor every day, so it doesn't seem likely that that's where the problem is... I'm guessing it's got to do with how the monitor handles HDMI or some such thing but I don't seem to be able to find much of a comment from anyone else on the net, so here I am... I considered sacrificing a goat at full moon, but I'm not entirely convinced that'll do much either and I upgraded to Lion as I saw a throwaway comment somewhere from someone, indicating that that might or might not have helped them with a slightly similar problem... So this problem now spans 10.6 AND 10.7...Â

I have a macbook with leopard osx and use it frequently for presentations and so on. I have connected it to several monitors and projectors a hundred times and it has worked fine since last night.
Last night, I have connected my mac to a monitor with vga cable but it did not detect it and instead a constantly flickering blue screen came up and never went. I am sure the cables are fine.
I finally got my 62" Plasma .. and I want to watch movies with it using my MacBook unibody... I already have mini Dp --> HDMI adapter which works flawless, but My macbook is sitting on the desk about 5 m to the right of the screen so I can't see my mouse moving on the Plasma.When I choose to clone the screen, it will set the Plasma to my Macbook's Resolution, which is not what I had in mind... is there any way i can set my macbooks resloution to FULL-HD?I know my screen can only display 1280x800 pixel at once, but is there a way to make OSX think that this is a Full HD screen? so kinda like a little bit zoomed in Full HD display ? I would be fine if it could work like the magnifying glass (ctrl + scroll)
the second option would be to buy a external 22-24" Full HD monitor for my Desk and a HDMI Y Splitter, i have a 22" but its not full HD (16:10) would that work better if I just use that instead of the built in macbook screen (+ aHDMI y Splitter)
I just got a new mac pro dual quad core to replace my single dual core for work. Im trying to pull my Nividi Quadro 4500 out of my old machine that i had installed by apple in to my new machine. i get it all hoked in right but when i turn on my new machine it dosnt detect the display. Any suggestions?

I'm looking to have a display hookup in my room for my Macbook Pro 15". I can't decide if i should get a 26" 720p HDTV with a pc input or a large lcd desktop display with a cable input to watch tv.
What are the pros/cons? Has anyone tried/preferred either? Any recommended monitors or hdtvs?
I have a 27" imac and have been using an apple led cinema display with it. I have had no problems with the display until today. Yesterday I installed windows 7 via bootcamp and had some trouble with the second display being detected but after downloading all of the bootcamp updates it worked fine. Today I restart my computer back into OSX and the display does not work. I tried resetting the PRam or whatever but that didnt do anything. When I go to system preferences > display there is no longer an option to detect display and there are no longer options to change the screen resolution.
I spoke with an apple tech who has me installing an update but I dont think she really knew what was going on and I doubt this will work. When I reboot back into the windows partition the display works during start up and I see the windows logo. So I dont think its a hardware issue (also the display still works fine with my macbook pro). But as soon as startup finishes I get a black screen. Under the control panel windows still recognizes that there is a 2nd display attached and you can still drag items over to the other screen, I just cant see anything. All black.
I recently received a late 2007 mac mini as a hand me down from my parents and I'm trying to hook it up to a Sony HDTV via HDMI to DVI cable. I bought the cables I needed and attempted to set it up, however when I turn on the system nothing appears on the display. I've been searching posts and various forums, but haven't really made any progress because most troubleshooting guides are focused upon display problems like pixels and refreshes.
Unfortunately I don't have a VGA monitor to use (which is what the mini was previously used on) to try and see if that works.
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.

However Ive just bought a LG M2794D 1080p tv/monitor and now have a problem. The TV is showing it recognises when the HDMI cable is connected to the macbook (on the screen the input menu shows live connections) or not through HDMI cable and mini-DVI to HDMI connector but the macbook does not recognise any external monitor. In display preferences there is no arrangement tab either and no resolution greater than 1280 x 800. Of course the TV has full 1080p resolution.
View 1 Replies View RelatedI have a Macbook Pro 2.16 Core Duo, and I'm wanting to install 10.6, but about a year ago, I cracked my screen to the point that I cannot make anything out on it, and haven't replaced it. Instead, I have just been using it in clamshell mode, which has worked out fine so far. My problem is that I cannot get the 10.6 install to show up on my external monitor.
I searched around, and could only find one other similar thread that just ended with the author putting it in clamshell and having it work fine. When I boot to the install and close the screen, I just get a grey box on my external display with a black bar on either side of it. I can't seem to find any other resources, so I'm not entirely sure what to do at this point. Any help would be greatly appreciated.
a hotkey to detect new displays? I plug my Powerbook into my TV often and don't want the little Detect Display icon in my menu bar. It would be much easier just to use a hotkey, or even if I could set up a shortcut to do it.
View 4 Replies View RelatedI use two monitors: an Apple Cinema display and a Dell, which is display number 2. I installed SL and it was normal until I rebooted the first time. Now every time I boot up, the only display that is found is the Dell and I have to go into preferences and select "detect displays" to make the main one show up. It loads as if the Dell is the only display, and since it is smaller it messes up my desktop, lumping all my icons on top of each other. When I click "detect displays," it moves everything back to the Apple monitor, making it the main display as it should be, but it is all out of whack.

View 1 Replies View RelatedI have a Macbook Pro mid 2009 running Mavericks. I have an old 23" Cinema Display that uses a big chunky adaptor (ADC?) with a dual USB and Thunderbolt cable and it works well with it, however, I just bought a new Thunderbolt 27" display and it just won't detect it. I also notice that a lacie drive in the same Thunderbolt slot won't show up either. The old Cinema Display does still work however using that same slot so it's not actually dead. Puzzled! Â
I know this MBP is probably one of the first generation to have Thunderbolt but I've never used it for anything other than the old Cinema Display adaptor.Â

I am looking to for something that will let me take my HD antenna and get it to go to my display. Is there anything that will allow me to do that? I'm just looking for something that'll work with the HD antenna, I'm not really concerned about cable TV or anything like that.

I was wondering what connections I could use to view my hdtv via directtv thru the larger 27" LED cinema display?
I tried connecting the HDMI cable to HDMI satellite receiver box to hdmi port on mac mini and then using the display settings detect display. I also tried the mini DVI to HDMI connector directly to the LED cinema display port connection but could not get any HD reception to cinema display. What I could do is view the LED cinema display and picture of the cinema display to the monitor of the HDTV.

I recently bought two 2GB sticks of OWC 800 MHz ram for my Mac Pro.
My Mac Pro originally had two 1GB sticks, which worked fine, I just wanted more.
It seems that they don't work together. I've tried every possibly configuration. Is it the case that they just aren't going to work together because they are different sizes?
Right now, I have the two 2GB sticks in A1 and A2. And the stock 1GB sticks in B1 and B2. A1 and A2 gets detected, but B1 and B2 doesn't.
I have a Macbook and I just bought an iPhone 3G and it seems my mac is totally not responding to my iPhone.I have the latest updates but to no avail.I also have also just loaded intego virusbarrier 5. I heard that it is interfering with the sync of both devices. So how do resolve this problem without having to erase and re-install my harddisk

View 1 Replies View RelatedWith my dad's MacBook pro I was able to hook it up to our HDTV using a DVI to VGA adapter, but we were never able to hook up the audio. Have any of you connected your laptops to an HDTV? If there were a video plus audio solution, that would be ideal, but I'm guessing that is not the case. So is there a cheap video adapter I can buy? My TV has HDMI, VGA, and various component inputs.
