External monitors over DP

Hi,
Just bought two external monitors to my Elitebook 850 G1.
The monitors supports 2560x1440 resolution when connected to the two DP ports in the docing. This is working ok but after an hour or so, monitor update is incredible slow. Why?
Computer contains 1Gb video memory. Is this the reason? Is it possible to add memory?
I have no need for 3D, extremly color resolution. Simply just 2560x1440.......

Hi Olab,
To get your issue more exposure I would suggest posting it in the commercial forums since this is a commercial product. You can do this at Commercial Forums. You might like to see this document on  connecting for more than 2 monitors connected to your laptop. Note you laptop screen counts as 1 monitor.
Thanks.

  • Screen zoom on an external monitor over Airplay is broken

    I just updated to Mavericks and noticed that I have lost functionality. I mirror my MacBook Pro to an external Sharp monitor using Airplay. While I am mirroring and zoom in on my screen, my screen will zoom but not the external monitor. In 10.8 this worked perfectly. Does anybody have ideas for how to enable this or a workaround?

    Here is what I just made work for me - and it isn't perfectly what I want, but at least my students will be able to see what I am coding.
    In the Accessability Panel's Zoom settings I changed from Full Screen to Picture-In-Picture style zooming.
    This works, but I would rather have a full screen zoom.
    A side note: The cursor size, and grey scale work, but the color inversion and high contrast settings do not work on the mirrored display.
    It seems strange.

  • New External Monitor for Logic on MacBook Pro - Suggestions

    I'm in the painful process of updating my studio and now my large screen external monitor has started failing.
    I know if this a pretty general question more suited to the MacBook Pro forum but I'd like some input from folks used to working with an application like Logic in a home studio environment.
    I guess the issue for me is that I'm not getting any younger and my eyesight isn't what it used to be. One of the things specific to Logic and music software in general is that there are LOTS of very detailed dialog boxes with text that is not always height adjustable (yes I know about zooming and indeed I do lots of that but it gets quite distracting). The other factor is that I'm often recording and engineering myself which means I'll be sitting with a guitar in my lap or at a keyboard and can't always lean in too close to the monitor.
    I solved this by buying a large 26" Acer which sits on my desk behind the Mackie MCU. To my left I've got the MacBook 15.4" Pro on a keyboard stand above my MIDI controller at a 45 degree angle to the desk.
    It's worked quite well until the Acer seems to have become haunted. It will mysteriously reboot itself intermittently, going blank for a second, then showing the Acer logo and going back to picture. It will also turn itself on spontaneously when the computer is off (the status light is off and then turns itself on). It seems to detect when I'm in the middle of a really good session and starts resetting itself every 30 seconds or so. Then it will work fine sometimes for days or weeks at a time. I've checked it on 4 different computers, it malfunctions on all. I believe in may be a problem with one of the capacitors or the inverter, I'm not sure, but it's driving CRAZY at this point.
    And of course now it's 3 months out of warranty and may be more expensive to fix than buying a new one.
    So my issue is what monitor to replace it with. I've considered buying an Apple monitor, since the display is lovely to look at but there are a couple things that are deal breakers.
    It's expensive. Very expensive.
    Oddly you have to choose between a 24" and a 30", with nothing in between. Don't want to sound like Goldilocks here, but the 24 is tooooo small and the 30 is tooooo big.
    Yeah I know bigger is usually better but since they bumped the native resolution of the 30" up to 2560x1600 it's really sharp but things like the menu text get really quite small. Yes you can reset to a lower non native resolution, but then you loose the sharpness. I tested Logic in the store on the 30" and it did look great but I found I actually had to move my whole body around to see things at the top and bottom of the screen.
    Oh and did I mention that it's expensive? Jeez.
    The 24" now seems to look a bit small to me after using the same resolution (1920x1200) on the Acer's 26" screen. (Ok, I think it's actually 25.5 but hey that half an inch can make a big difference and I will avoid making any bad jokes here).
    And did I mention the Apple monitors are expensive? The 24" is almost 3 times as expensive as a cheaper alternative.
    I also still have a PC here that I use (sorry) and the Apple monitors have very limited connectivity. So I think unfortunately the Apple monitors are out for me.
    So I;m down to a couple other non Apple options. I will not buy an Acer again since I believe now that their quality control is not good and their support is absolutely atrocious. Shame I used to be a big fan of Acer PC's, but after owning a couple I'm steering clear.
    My biggest issue right now is that most of the new budget monitors are geared toward 1080p HD uses so they are they are maxing out at 1920x1080 (16:9 aspect ratio instead of 1920x1200's 16:10). So the tradeoff here is that HD movies will look better in 16:9, but 16:10 gives you "squarer" pixels and more vertical resolution for screen hungry apps like Logic.
    Any opinions on this? I'm a bit new to the Mac so I don't know if I'm really better off going with a 1920x1200 screen like the Apple monitors.
    Also, I know this may just be a bug in the Acer's scaling, but if I switch to 1920x1080, I lose the menus off the top of the screen or if I adjust the vpos I lose the dock at the bottom. Downscaling to 1600x1050 or even 1024x768 works fine. If I get a 1080 screen and set the resolution appropriately will it work correctly and without too much distortion?
    I'm also curious what is the best way to hook up the monitor? I'm currently using the DVI to VGA adapter that came with the MacBook. My Pro is the slighter older silver keyboard model so it has the standard DVI out. Will I see any real improvement by going over to using DVI directly?
    Also I'm wondering how people feel about glossy vs matte for music. My current displays are the non-glossy and I do think I prefer them for detail work.
    The candidates right now are
    Hanns-G HH-281HPB 28" @300$. It's one of the only budget monitors that uses 1920x1200. All the right inputs (DVI, VGA). I'm just afraid this might be a bit too good to be true. It's really cheap and after having problems with a "cheap" Acer (although it wasn't so cheap 3 years ago!) I don't want similar problems. Stand has no swivel or tilt (a big problem for my use). Also that resolution on such a big screen might be good for me or it might look grainy I don't know I haven't seen it. Anybody have any experience with these?
    Samsung P2770H 27" @339 Looks nice, good color. Sadly only 1080 native resolution. Stand doesn't swivel, but does tilt. No VGA input, so won't work with my old PC (although strangely it says it comes with a VGA cable). They get generally good reviews and I know Samsung makes very good flat panel TV's.
    ViewSonic X Series VX2739WM 27" @350. Once again maxes out at 1080. It's fast (1ms), has VGA input. I've never been a big fan of ViewSonic but they do seem to have gotten better color-wise. Tilt no swivel and it's anti-glare (not sure this is a plus).
    There are also similar options from HP, Asus, LG and Sceptre but they are all 1080. In fact outside of the Apples, the Hanns-G and a few expensive monitors from NEC they all seem to be 1080. So if I really want the 1200 the Hanns-G seems like the only way to go.
    Any input here would be greatly appreciated.

    No doubt, the Apple displays are gorgeous. The first time I saw the 30" display wow, I wanted one BAD and it's actually what prompted me to buy a "big" monitor. The colors are great with a rich wonderful saturation level and as usual for Apple the form factor design is stunning. You know for that picture quality I could even get over the sticker shock and save up for one.
    Which is why I was so disappointed when I actually sat down in the store and started to use Logic on one. I imagine for doing video work, graphic design or darn near anything else, it would be great. But for Logic I just found myself bending and twisting trying to look at toolbar at the bottom and then up to look at the menus. And instrument or plugin displays that were hard coded to look OK at lower resolutions looked really, really tiny to me. For me and particularly using Logic having 2 slightly smaller displays at a 45 degree angle makes more sense.
    And once again the 24 seems just a bit small. I don't understand why they have a 27" iMac but you can't buy a 27" display. So iMac 27" starting at 1699, subtract out the cost of the CPU and drive ie the Mini and I'd really buy one. Strangely you can buy a 21.5" or a 27" iMac. Or you can buy a 24" or 30" display. Hmmmm.
    So don't get me wrong I'm not bashing Apple for being expensive. They put a lot of money into R&D and into really thinking about the form and the function of their products. As a recent convert from being a PC developer for 25+ years, hey I've more than sipped the Kool-Aid here, I've guzzled it. They make great products and yeah they're more expensive, because they ARE better! I've now got 2 MBP's, 2 iPods, I'm about to get an iPhone (silly "death grip" or not) and I really want an iPad. Heck I'd really love an 8 core MacPro if I could afford one (alas I can't).
    I guess my only gripe here is that there always seems to be a little less choice in the Apple world. Yeah, I know they do a lot less volume than the PC clone world I just think that they always seem to have a big gap between the high end and low end with not enough in between. So you can choose between the lower end and one piece units with no expansion boards (the mini or the iMac) or go straight to monster tower MacPro (way over 3K with display). You can get a MacBook but then you have to put up with a small screen or go with MacBook Pro, which let's face it is a lot of computing power for someone who just wants to web surf and write some email without squinting.
    So here I am stuck in the middle. I don't want to buy a HannspreeQG or another piece of junk that's going to last 3 years and 3 months because of a crappy $2 capacitor that no seems to able to fix or care about fixing. I'd like to buy a really nice Apple monitor, I just want a big monitor, not a huge one and not a "medium" one (I know I'm spoiled but 24" seems "medium" these days).
    Sorry about the rant here but my monitor is shutting down every 30 seconds and I'm about to go completely insane and toss it out the window!!!
    Really glad to hear about that 84' VGA cable. I never imagined such a thing existed or would work without some sort of signal boost on the way. Very cool for me. My electronic drum kit is in another room and I would love to have a small cheap monitor next to it for sequencing. I had my laptop on a stand next to it for a while but I began to get terrified that I'd let a drumstick slip and destroy my laptop screen. That would be a very bad thing. Thanks for the tip.

  • Use an external monitor with my MacBook Pro

    I have my MacBook Pro (13" Spring 2010) and I would like to extend my desktop over to my Gateway FH2300 however Lion is giving me some issues.
    For one after I make my external monitor my primary monitor in the appearnce tab in Settings some apps appear on my MacBook Pro but I can't drag it over to my other dektop because my mouse cursor is confined to that monitor. In Windows 7 my 2 monitors work flaulsly and I can easily drag and work with apps in between both windows.
    What can I do to fix this?
    Thanks in advance.

    Remember that your monitors probably aren't the same size.  Look at the placement in System Preferences > Displays > Arrangement tab.  Your mouse will only move over the section that overlaps.  Places like the bottom of this sample it won't.

  • Mini DisplayPort to VGA isn't working. It won't recognize any external monitor. It worked just fine with my older spring 2011 MacBook Pro running Snow Leopard, but now with my brand new 2012 MacBook Pro running Mountain Lion, it no longer works

    I just bought a new MacBook Pro this summer and was all excited. But I'm very frustrated right now because I can't connect to any external monitors through VGA. My thunderbolt (DisplayPort Mini) to HDMI works just fine, but when I try with my other connector to go from Thunderbolt (DisplayPort Mini) to VGA, Nothing works. my screen goes blue and changes size like it recognized something but nothing is ever detected on the external moniter or projector. I'm not sure what is wrong but it's very frustrating. I'm just very depressed that it worked just fine with my 2-year-old MacBook Pro but isn't working now. I'm running OS X 10.8.2. I just upgraded yesterday from 10.8.1 but that upgrade did nothing to fix my problem. Can anyone help? Thanks

    I am haveing this exact same issue. I have plugging in 3 monitors and tried two different VGA to mini displayport and nothing is working. I recently bought a Acer monitor and it work for an hour and now it back to doing the same thing.
    When I plug the VGA adapter in to the monitor the monitor think its not connected to a computer then when disconnecting the VGA adapter the monitor thinks it is connected to a computer.
    NEED SOME HELP!!! at the point of all my hair is pulled out.

    that is the same problem i am having! if anyone can help that would be great i'm losing my mind over here

  • Possibly mundane Mini-DVI to VGA into an external monitor problem

    Hi,
    I've had a look over the interwebs regarding my problem and it seems as if it's not unusual to have external monitor problems but I'm not sure if mine is slightly different:
    I had a perfectly working set up with my new Macbook (the white one, '06 model I believe), that was connected to my Hanns-G HU196D monitor via a mini-DVI to VGA adapter, no problems whatsoever. But for a couple of weeks now my Macbook just flickers a light blue colour, with nothing at all on the monitor, and my macbook is unusable until I remove the adapter. I've read about updating firmware but I can't see my desktop once the macbook is connected to the monitor so it's not possible to configure anything. I've read somewhere that my external monitor isn't compatible with this set up, but it was until a couple of weeks ago!
    My Macbook's 4 months old now and since then I've bought a new mini-dvi to vga adapter and a new VGA cable, no connections seem loose on either mini-dvi port or my monitor's vga port.
    Thanks if you can help!
    Jack

    You will need to use a mini Dvi-dvi and a dvi-svideo/rca adapter.
    Joy joy hallelujah.
    Pardon the sarcasm...I just wasted 3 hours of my life trying to sort the issue out.
    Heard a KWORLD PlusTV PCTOTV Converter SA235 USB 2.0 Interface would sort the issue out for under 40$ but it's not Mac.
    Hope that helps.

  • After Logic Board replacement Built in Display not working but External Monitor is

    Had to replace logic board in my Mid 2009 17' MBP as it wasn't powering up at all.
    Since putting in refurbished logic board MBP powers up and actually works perfectly with an external monitor but built in display is dead.
    In 'About My Mac' initially it showed Color LCD as being connected., but now it doent.
    Can anyone tell me if this is a problem of the refurbushed logic bioard from this ionfo - or if there is a w ay of being 100% sure that it is the logic board and not the display.

    Shine a bright light at the screen and see if the picture is there, but the backlight is not there.
    Working inside MacBook is very fussy work, and it is far too easy to make connections that seem fine, but do not quite work, or to disturb earlier work during re-assembly. Just to vex you even more, the screen connections go through the hinge area, and are subject to constant movement and stress.
    I tend to first blame the last thing you changed (working inside your Mac in this case) as the source of the problem over random failure, until I can use classic techniques (such as substituting know-good parts) to rule random failures in or out.
    If you did not follow proper grounding and static-elimination techniques, you can cause major damage inside. Tiny shocks can ruin electronics long before you feel the spark.

  • HDTV as external monitor using ethernet connection

    Hello,

  • Thinkpad T420 with Dock 4338 Dual External Monitors won't work

    Hey Everyone,
          I recently purchased a T420 with Dock Model 4338 and am trying to connect two external monitors.  I want to have my desktop visible on my primary monitor with laptop closed and that desktop extended onto my second external monitors.  Both external monitors are Dell 19", one is being ran through the VGA port on the dock and the other is a VGA cord that I put a VGA to DVI-D adapter on to run off of one of the DVI Ports on the dock.  I can get my desktop to display on the main external monitor, and everything detects the other monitor fine, but the extended monitor remains black.  The screen is on, and recognized as the button light on the monitor is green not yellow and i can scroll my mouse over to that window and i lose the mouse so it's extending just not visible.  I have made sure that both monitors work by checking each individually in the VGA port and they are operational, but the DVI-D port doesn't seem to work on my second monitor.  
         I have done some pretty extensive searching and can't seem to get this to work.  At my job I have a T430 with the same dock and dual monitor setup that took no time and works great.  Does the T420 just not support this?
    All help is appreciated.
    Thank you all,

    DVI-D don't support passive dvi to VGA adapter. You are better off with a displayport to VGA adapter, as they are cheaper then a dvi-d to VGA converter.

  • External monitor in BootCamp?

    I have just ordered a new MacBook to replace my older MacBook Pro and have heard that you cannot use an external monitor (or projector) in BootCamp with a MacBook. Actually I was pointed to an Apple doc that says you can't use external monitors with either the Macbook or Macbook Pro...which I know isn't accurate, as I've used my Macbook Pro with various displays and projectors in Bootcamp since I got it over 2 years ago. Can anyone confirm that you can use the mini-DVI to VGA adapter in Bootcamp? I need it to run some presentation software. thanks!

  • Macbook Pro Retina External Monitor Blurry

    Just got a new macbook pro retina and got it home. After getting everything transferred over from my old toshiba I connected it to my 1 month old HP external monitor and the display is blurry. I have read on many sites that this is a common problem however I can not find a solution. I am hook up from HDMI to HDMI. O don't really want to go through trial and error of different adapter for the lightning port if that will not work. I have tried different HDMI cables to no success. Any Ideas?

    Hi AO1 James,
    If I understand correctly, the external monitor was blurry from the moment you plugged it into your MacBook Pro with Retina display. I would first check the resolution settings for the monitor with the "How do I select additional resolutions on my display?" section of the following article:
    Apple computers: Troubleshooting issues with video on internal or external displays
    If it remains blurry after selecting your monitors optimal resolution, I would use the steps under the "Reset the system" section of the article to help troubleshoot the issue.
    Thank you for using Apple Support Communities.
    All the best,
    Sterling

  • External monitor resolution in Vista on MacBook Pro

    I am running Vista Ultimate on a MacBook Pro. I have a Dell 24" external monitor plugged in, which supports a top resolution of 1920 x 1200. But Vista thinks it's a generic non-PnP monitor with a top resolution of 1024 x 768. I have installed the Windows drivers from my Leopard disk, but neither the Vista Displays control panel nor the nVidia software think the resolution of this monitor can go any higher. I tried looking on nVidia's site for newer drivers, but they said for the M series video cards to go to the computer manufacturer for drivers because they modify them for power consumption and other special needs.

    I found the solution.

  • External monitor goes black when macbook pro has magsafe connected

    Hi,
    I have bought an external monitor about 1 week ago, and I have it connected with a minidisplay to dvi cable, and a dvi cable to the monitor.
    It was working OK -well, it had some sudden flash to black screen that lasted about 1 second, but nothing else- until thir morning when it just started showing a black screen. Mac OS sees the monitor, and I can move windows over there, etc. It's "alive". But I only see a black screen on the monitor.
    I tested with other computer, and it works OK. The cables work too.
    What I discovered is that if I unplug the power adaptor from the MBP the monitor screen shows correctly.
    It works OK only if the magsafe adaptor is unplugged from the MBP, it doesn't care if the magsafe adaptor is plugged to the power or not; only if it's connected to the mac book pro.
    It seems like some magnet stuff is making a mess there. What could it be? I can't work on the monitor only in battery power...
    I tried resetting nvram and the other stuffs that I found here, but nothing works.
    Thanks!

  • 2010 Macbook Pro 17 display on external monitor only after power on

    THis has happened a few times over the past 6 weeks - I power on first thing in the morning and the primary screen is black, and the login screen appears on the external monitor. Shutting it down and starting up again does the same thing. When it happened before I'd power off, remove the external display, power on and then I'd get the primary display back agin but it's not working this time and I've only got the external display working.
    Is there a utility to 'kick' the graphics into the correct mode, or is this some type of hardware problem?
    Thanks,
    Graham

    The primary laptop monitor starts blank, and only the external monitor is working.
    If I shutdown, unplug the external monitor and power back on the laptop screen stays blank. If I plug the external monitor in the screen that would normally have been on the primary laptop screen is on the external monitor, and the laptop screen remains blank. At this point I can only work with an external monitor plugged in, and that limits my portability a bit
