Mac Pro :: Display Going Black Connected Via USB Converter
Sep 19, 2010
I've got an 08 Mac Pro with a 30" ACD hooked up to it as well as a 24" Apple LED display (via a MDP to (DVI?) converter) and I'm having some problems. Basically, sometimes the screens go black. It can be when the computer turns on, that one (never both) doesn't turn on... or, when waking from sleep, or, one just goes black at some point. I ran TechTool Deluxe on the Mac Pro and the GPU passed the test just fine. FYI The converter is USB powered.
I have a 19-inch Envision EN9410e LCD flat panel monitor. Right now I did a mirror display setup. The native resolution of this monitor is 1280 x 1024. When I went to System Preferences to change it to that resolution my LCD monitor shows the Snow Leopard desktop but it's in the middle of two black bars. I had to revert to 1024 x 768 resolution to not have the black bars show. Is there a way I can change it to the native resolution and not have the black bars on the top and bottom show up on the screen?
I have a 2 month old 13" MBP which I absolutely love. The only hitch is that there is an oddity when connected to my Dell 2008wfp display. It only happens when I wake the MBP from sleep. A number of things happen sometimes. Usuaully, when I wake the MBP from sleep, i get a black screen on both displays and all I can see and control is the cursor. Sometimes the main display will be black, but the MBP display will show the desktop wallpaper, but again, I can only see and control the mouse cursor. It should also be worth mentioning that the keyboard is rendered non-functional as well.
Sometimes, OS X will appear on both displays, with mouse cursor active, keyboard inactive, but I am unable to click anything or interact with anything OS X.
Anyway, I'm at the point where I need to mention this because it happens quite frequently and its getting rather annoying. The only way I can get out of this hang, is to cold reboot the machine. It happens everyday and at least 50% of the time I wake the MBP from sleep. When not connected to the display, I never get this occurrence. Also, this display worked perfectly when I used to own the classic 15" MBP, so its hard for me to pinpoint what exactly is the anomaly that is happening.
Anyone else experiencing this same issue? I am using a mini display port to DVI adapter to the Dell display.
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.
I use MBP (late 2011). I find the hunderbolt port to be similar to the mini-display port of older mac. I wish to have another display, but not ready to spend $999 over a thunderbolt display from mac. So would like to know if a Mini-diaplay port converter from apple would help me connect a exernal display via the thunderbolt port?
I came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?
I hooked up my macbook pro to a mini display port to a dvi -> hdmi to my tv no problem. However, when I hooked up the mini display -> dell monitor, I get nothing. The screen is black. The weird thing is that my macbook pro recognizes that a second monitor is plugged in... it just won't display anything
I see that the Gefen DVI to Mini DisplayPort converter is on sale at MacMall for $82. See the link below. I'm wondering if anyone has used this for PC gaming? I've got a good gaming PC. I have a 24" ACD that I use with my MacBook Pro. I'm wondering if using this converter would be good with PC gaming. I understand the thing does active conversion since native is not possible between the two formats. Any chance this thing would slow down the signal and hinder PC gaming performance?
i have a macbook pro and recently got a new Tv its a LG 42pq30 and i also have a sony STR-KS2300 home theather system so my setup goes like this miniDP apater is pluged in my macbook hdmi cable is pluged in that adapter the other end of a cable goes into home theather system and an hdmi cable is going from sony to my lg tv everyhing works fine execpt that the video would go black for a couple soconds one time it would go black every 5min the other time every 2hours
ps i had another samsung older tv that was conected the same way everything was perfect execpt that the tv didnt have 1080p
My macbook is running Mavericks OS X 10.9.4, and I'm having difficulty getting rid of the vertical black columns on my computer screen when it is connected to my classroom projector. I've played with the resolutions, and the best resolution for the VGA display is 1024x768...Unfortunately this creates less than desirable black columns on my computer screen. Another teacher in my school has display settings of "1024x768 stretched," and her macbook does not have the issue mine does. However, I don't think she is running Mavericks 10.9.4. I cannot find this display option on my computer.
So i bought a mini display port to hdmi converter and im running an hdmi to RCA cable from to my tv. I dont really know how to set it up to put out the video. I went into displays and clicked detect displays and nothing showed up and theres nothing but a blue screen on my tv.
My macbook pro 15's screen is dead and I don't want to buy a new one. I've been using it connected to my tv for a while now and the display has started to feel irritating and unnecessary so I wanna get rid of it completely.
I have my TV connected to my computer so when I'm going to watch a movie I drag it over there. But I don't want it like that all the time, for instance when I play games it's really irritating if I drag the mouse to much to the side it goes out to the TV. How do I turn it off? In Linux and Windows it's no problem at all, but in OS X I can't find that option?
As the title states. I am looking for an external display that matches the display on my black MacBook. I want one with the same gloss finish as my MacBook, this way I can calibrate both screens to look the same. That way when I switch screens it doesn't look different.
Anyone know of a screen that looks identical to the (previous generation) MacBook? I was thinking of getting a Samsung T240 but it has a different finish. How are ASUS screens? Any screens out there that have the same gloss finish?
I have a MacBook Pro 13'' (mid 09) and another MacBook pro 15'' (early 09). The problem below applies to both of them.
I often use my 15'' mbp connected to a usb keyboard, mouse, display etc. Basically it is used as a stationary computer that can be easily moved (to work/school etc). This is my main laptop so this is where I noticed the problem first. Sometimes when just using the computer as normal (using itunes, opera, adium etc) the OS X will just suddenly become very sluggish and unresponsive.
However it is not OS X itself, but the GUI! Example: if I move my mouse over the dock, it wont animate. If I try to do any finder related action the GUI response is way of and if I try to do something in the menubar I have to hold left click, if I let go it just closes the menu.
This goes for the application folder as well (I have it as a list). Normally it will just funtion as normal but when this problem occurs I have cant let go of the mouse button when moving through the menus because then the menu closes!
I use my MBP connected to a Dell U2410 and everything has been ok for the last 5 months or so (I got the MBP around the beginning of Feb.). However recently, my display will start flickering (blinking) a blue screen up to the point that it is completely unusable. Often if I simply unplug the mini displayport from the mbp and plug it back in again, everything goes back to normal for awhile. Just now I was able, between flickers, to switch from the integrated graphics card to the dedicated (?) graphics card. Although I did get a few flickers logging back in, so far it's been ok.
When I connect my 13" MBP to an external display to watch a movie etc. the external display seems to be darker than it would appear if I was watching on my MBP. Is there anything I can do to make things brighter (other than turning the brightness up on my TV)?
I have a 2009 Mac Mini connected to a 22" LG monitor via Mini-DVI port and it's also connected to a 50" Pioneer Plasma (in the next room) via Mini-Displayport. Everything works perfect except that when I turn off the Pioneer Plasma, my mouse can still scroll over from the LG monitor to the Plasma.
I've also noticed that my screensaver is laggy even when the Plasma is turned off (usually that happens when it's drawing the screensaver on both screens) so it must still be sending a video signal out of the Mini Displayport.
I have a macbook pro purchased last June. Want to connect an external display and the only option is usb. Apple does not make a minidisplay to usb adaptor and I can not find one on line. Computer will not recognize the display connected directly to the usb. What can I do?
My Macbook Pro (15 in 2 GHz core i7) absolutely crawls when I plug in the thunderbolt display. I'm running on snow leopard with 4 gigs of memory. Ive made all the neccesary updates. I plug in the screen and close my laptop and the computer gets unbearably slow. Once I open it up it gets way better and when I unplug the display it goes back to 100% speed. Ive called apple and they cant figure it out. Ive taken it to the apple store and they tell me they cant figure it out.
I have a late 2011 15" macbook pro running latest lion os that suddenly - when connected to my 24" cinema dislay - speeds up the fan. I have tried to reset both pram and smc, but still it heats up when I connect to the display. What to do?
Info: MacBook Pro, Mac OS X (10.7.3), 15" Late 2011
so i am REALLY new to all this monitor stuff. I have always had "package deals" where I never really needed to worry about the connections on my monitors working.. or i've had imacs. Anyways.. i have a MBP that I would LIKE to have hooked up to an older Apple Studio Monitor. Now, I know that the MBP video card does NOT supply power to the monitor, and that this monitor NEEDS power to come from that cable (the monitor does not have a separate power plug) So i know i need some type of converter that will send power to my monitor.. WHAT IS THIS CABLE??
I have read about the AT-DP200 but the more i read, the more confused I get.. At first i thought it was right.. but then im starting to think this does the opposite.. that its for older computers and newer monitors. or is THIS what i need? I DONT KNOW!! Please point me in the right direction.. I just need to know what will work.. I REALLY want to get this set up..
My Mac mini is connected to a Samsung widescreen (1360x768) display using mini port to VGA adapter. When starting, the both sides of the screen is not used, left black. Mac mini thinks the display is a 4:3 display, but does not recognize this as a 16:9 display. What can I do?
Sporadically when I hit the key to lower the display's brightness level, instead just dimming it one step down it jumps all the way to the lowest setting making it completely dark. I have had my MBP for about 8 months and never had this problem until the last couple days. Does this have to do with the most recent OS X update? Anyone else having this issue??
