MacBook overscan on 1080p

I recently connected my MacBook to my new asus ve246 24 inch monitor. The monitor has a 1080p max resoultion and is connected to the MacBook using a minidvi to hdmi cable. Now when I use the monitor in clamshell mode (the MacBook screen is closed and picture is only on monitor) it seems like the display is fine but when I check in the settings, the overscan button is checked. If I unchecked it, it displays a 1 inch black bar on all sides of the monitor and the picture also isn't sharp anymore. The resolution stays the same at 1080p for both with overscan and without overscan. I have overscan on right now and resolution is set to 1080p but am I watching real 1920x1080 or is is scaled up version of a lesser resolution??? I have also checked my monitor many times, it has no setting to scale or anything like that. Also my MacBook does recognize the monitor because it says ve246 on the display screen. Another thing is that when I look at a 1080p test image online, it covers the whole screen like it supposed to and doesn't go off. But for some reason the text doesn't feel as sharp to me. Does anyone know more about this?

  • DVI to HDMI overscan issue 1080p

    Hello,
    I have a LCD Samsung LE46A656 FullHD and a new macbook pro late 2008.
    And have the 1080p resolution sized in mac osx but on the lcd left and right a black free place.
    i see this thread, and a solution for 720p, now i search one for 1080p:
    http://discussions.apple.com/thread.jspa?messageID=6405017
    Please help me

    If you go to "System Preferences" and check "Displays" when it's connected to the LCD, is "Mirroring" selected?
    Sometimes if you use a photo with a black background as your desktop background photo, an attached Monitor will appear completely black . . . unless "Mirroring" is selected.
    May be your problem is harder to solve than my solution, but doesn't hurt to try.
    Let me know if that solves it.

  • Overscan with 1080p Mitsubishi 57731

    I've read alot about HDTV's having overscan occur when hooked up to a computer. I have my Mac mini hooked up via the DVI input with 1080p accepted as native resolution. Overscan occurs and I'm forced to format a 1080p reduced mode to remove the overscan but it does take about an inch away from each area of the screen. My problem is the reduced mode isn't nearly as sharp the normal 1080p(I'm older and my eyes strain more now). Anyone have any experience with this brand TV(Mitusubishi 57731) or using the switch res program to remove the front porch settings etc? Also if I change the front porch settings etc will that prevent a full 1080p signal?

    +I've read alot about HDTV's having overscan occur when hooked up to a computer.+
    Yes, and this is especially true of DLPs and other RPTVs (rear projection TVs) because, by design, they are set to have overscan. They never actually show their true resolution on the screen. So even though your Mits has a 1080p engine in it, you never see that many pixels on the screen.
    +I have my Mac mini hooked up via the DVI input with 1080p accepted as native resolution.+
    Well, from reading your TVs user manual on-line, I'd say you are lucky to have gotten that far. Pages 89 and 90 do not present a very rosy picture for being able to do that. For example, page 89, under section titled "PC Viewing" it says, "Your Mitsubishi TV can display resolutions from standard VGA (640 x 480) through XGA (1024 x 768) 60-Hz refresh rates only." So that's good you got it to run from 1080p from the mini. The manual for that TV suggests that shouldn't even be possible.
    +Overscan occurs and I'm forced to format a 1080p reduced mode to remove the overscan but it does take about an inch away from each area of the screen.+
    As stated, in a DLP set, overscan is always present. It's just not obvious with typical source material like TV and movies because you can't tell where the edges are to begin with. A computer's output is totally different in that regard because where the edges are is made very obvious by things like the OS X menu bar and dock.
    +My problem is the reduced mode isn't nearly as sharp the normal 1080p(I'm older and my eyes strain more now).+
    That's because scaling is taking place and there is no longer a one-for-one relationship between pixels in video memory and pixels on screen. The 1920 x 1080 pixels are being squeezed into a reduced area and the clarity will suffer.
    +Anyone have any experience with this brand TV(Mitusubishi 57731) or using the switch res program to remove the front porch settings etc?+
    I own a Mits LCD 1080p TV that I have hooked to my mini and it's working nicely, out-of-the-box, and I didn't need to use SwitchRes X. But I don't own a DLP set so can't comment specifically on configuring SwitchRes X or DisplayConfigX to try and get the display working better. It may not even be possible. Certainly you cannot get true 1080p to display native with all the pixels on the screen. That just can't happen.
    +Also if I change the front porch settings etc will that prevent a full 1080p signal?+
    No, fiddling with porches does not alter the original format. But neither does it typically have any predictable affect on the image size displayed on a digital TV set.
    Have you tried the AVS Forum? There are a couple threads there that might be of interest to you, and at least you'd be communicating with people that own the exact same or similar TV.

  • Macbook air airplay 1080P?

    Can mid-2011 Macbook Air 1080P airplay mirror to ATV3 at 1080P?  I have been having trouble with this.  The video does not take up the full screen on my TV through the ATV, since the "best for airplay" or "scaled" resolution options only offer 720P or, at max 1440x900 which is the native LCD resolution.

    Airplay does support 1080p. Unfortunately,  airplay mirroring on supported Macs is limited to 720p video streaming. Since Macbook Air's do not have a dedicated graphics card like Macbook Pro 15", it can not take advantage of its graphics capability and stream at full 1080p resolution.

  • MacBook Pro 13inch, 1080p Output?

    Does the current MBP 13inch output (to a monitor) a "Full HD 1920x1080 signal?

    Hi mawxi,
    I have the same problem and i resurged the topic nearly two weeks now. For me it's important to play video native 24p and audio with SPDIF 5.1
    My way:
    1.) OSX: There is only the way to buy the software "switchresX". I found no other way to change the frequency to 24Hz. If tested it and it worked.
    --> If anyone know more please share the information with us!
    2.) Vista: I used bootcamp to install Vista. After installing all vista updates, i downloaded the nvidia driver "nvidia 8900M GT" from the nvidia homepage. It worked and there i can choose the 24Hz.
    Now i searched the audio driver and the Wifi driver. (Normally those drivers should be included at the OSX disc but not at my one) I found them here:
    http://catalog.update.microsoft.com/v7/site/Home.aspx
    Yes! You have to use the internet Explorer, but here you find all you need.
    search: "Broadcom 802" for Wifi and "Realtek" for audio, sort the list by Date.
    Well, now i can use my 2000€ MacBook Pro to watch 24p movies with 5.1 sound on my fullhd beamer and 7.1 yamaha receiver.

  • Why does my macbook only display 1024x768 on my 1080p tv?

    Hello, I have a mid 2007 macbook with osx lion. I connected it to my 1080p TV with a mini-dvi to vga connector. When i plug it into the TV it only shows the resolutions up to 1024x768. I know my macbook can output 1080p because I did it on windows 7 through bootcamp. I want to use my mac side because its a mac only program. Any help or advice would be very much appreciated. Thank you!

    I would try two things the first being resetting the System Management Controller:
    1) If the computer is on, turn it off.
    2) Disconnect the AC Adapter and remove the computer's battery.
    3) Press and hold down the power button for 5 seconds and then release the button.
    4) Reconnect the battery and AC Adapter.
    5) Press the Power button to restart the computer.
    If that doesn't work I would recalibrate the battery.
    To calibrate the battery:
    1) Plug in the MagSafe power adapter and fully charge the MacBook or MacBook Pro battery until the light on the MagSafe connector changes to green and the Battery icon in the menu bar indicates that the battery is fully charged.
    2) Allow the battery to rest in the fully charged state for two hours or longer. You may use your computer during this time as long as the power adapter is plugged in.
    3) Disconnect the power adapter with the computer on and start using it with battery power. When the battery's charge gets low, you’ll see the low battery warning dialog on the screen.
    4) Continue to keep your computer turned on until it goes to sleep. Save your work and close all applications when the battery's charge gets low and before the computer goes to sleep.
    5) Turn off the computer or allow it to sleep for five hours or longer.
    6) Reconnect the power adapter and leave it connected until the battery is fully charged. You may use your computer during this time.

  • MBP wont display 1080p on monitor any more

    I have an early 2011 Macbook pro and a hp 2511x monitor. The setup worked flawlessly before I went off to school. Now that Im back home my macbook wont display 1080p on the monitor, only 720p. While attempting to display 1080p the monitor screen is blank but I am able to move my mouse over to the external dispaly just fine, just no picture. My mac will display 1080p on other external monitors & the monitor will work fine with other computers or xbox on 1080p.
    Just upgraded from 10.7 to 10.9 and still not working properly.

  • Setting resolution for viewing TV and movies on HDTV?

    Last night I played around with watching Apple TV through iTunes using my MacBook Pro and 1080p TV. Conncection is made via a DVI to HDMI cable, with a separate mini-plug to RCA cable from the headphone output for audio. I can open Preferences on the Mac and set the resolution for the TV, but there is no 1080 option (1920 X 1080). The video card should support external monitor resolutions up to 2560 by 1600 pixels but I only see resolution options (for both the built in and HDTV) up to 1440 by 900 (native for the Mac's display).
    The TV is recognized by the Mac, but the resolutions available are identical between the two, and changing resolution on one changes it on both.
    Suggestions on which resolution to use? Or how to "unlock" the higher resolutions to get to 1920 by 1080?
    Thanks!

    Turn Mirroring off in Displays Preferences.

  • External monitor compatibility

    Does anyone know if the black macbook is compatible with a Full HD 1080p LCD monitor? If so, what adapter do I need to make it work with the macbook

    I have used macbooks with a 1080p monitor before. I just use VGA, but DVI should also work

  • In youtube, certain videos jitter and shake

    This is at 480p but my macbook can handle 1080p videos. The sound is okay on the videos that jiter aswell.
    The videos work fine on other computers aswell.
    I went to the genius bar today and they wiped my Hard-drive. It was fine after that, so I upgraded to 10.6.7 and what not, got latest flash and it's shaking again ...
    Anyone have any ideas? It's a macbook, white unibody with 2.26ghz intel core 2 duo, 2gb ram and 9400gt gfx card I think
    All help is greatly appreciated
    Sean

    I have the same problem as the original poster...it's rather annoying. It happens in Firefox 5.0.1, the latest version of Google Chrome, AND Safari.
    At 360p and 240p, the video runs just fine but as soon as I bump it up to 480p, 720p, or 1080p, it becomes really choppy and the video stutters. The audio remains fine however.
    For example, the music video for the Pet Shop Boy's "West End Girls" song has this effect.
    http://www.youtube.com/watch?v=p3j2NYZ8FKs
    However some other videos do not have this jitter effect and run perfectly fine such as the "Harry Potter and the Deathly Hallows - Part 2 Trailer" or even the Pet Shop Boy's music video for "Love etc."

  • External monitor resolution is too low

    Fairly simple problem, but I can't find out where is the issue.
    I got:
    - Macbook pro dual core 2 (mid 2010)
    - iiyama prolite pl2409hdsb-1 (24'',native resolution 1920x1080)
    - Apple Mini DisplayPort to DVI adapter
    I thought I would be able to use the native resolution of the screen, but in OS preferencies, the max resolution I can reach is 1600x900 px, pretty horrible!
    Any thought?
    Cheers

    I just tried with a macbook air, works super fine, even in DVI.
    So the problem seems to come from my mpb, but it says here, under "2nd Display Support" that the maximum supported resolution is 2560x1600.
    Is it again a question 2560x1600 not being a HD resolution?
    note: the format of the resolution name with the macbook air is "1080p" instead of "YYYxYYY", that's weird.
    note 2: I'm currently running OS 10.6.8, any chance a software update might solve the issue?

  • MacBook Pro mid-2010 15-inch Supports Monitor at 720p but not 1080p

    Hello all,
    Systems Specs:
    MacBook Pro (15-inch, Mid 2010)
    Processor: 2.53 GHz Intel Core i5
    Memory: 4 GB 1067 MHz DDR3
    Startup Disk: Macintosh HD
    Graphics: NVIDIA GeForce GT 330M 256 MB
    I am attempting to connect my MBP to a new Asus VE278Q, 27inch 1920x1080. I use a mini-display port to HDMI monoprice cable. I can connect at 720p and the display looks fine. When I switch to 1080p the monitor flickers and turns to snow within a few seconds. My parents' 2013 MBP, using the same cable, can connect to the monitor and display perfectly.
    The technical specs for a mid-2010 MBP say that it can support  "up to 2560 by 1600 pixels on an external display." It should be able to support this monitor easily. I have also tried to connect it to a Sony 1080p TV, where it registered as black screen.
    Does anyone have any idea what is going on? Is there something wrong with my graphics card?

    what do i need to connect my mac book pro to the tv with the mac's thunderbolt port to hdmi? I have the newest macbook pro. I'm wanting to have the best picture I can get from my 1080p tv. thanks

    Thanks Community! I solved the problem. In fact it was not a problem but lack of understanding. These guys at Apple are way ahead in thir thinking. I will try to explain as short as I can.
    In Lion, ihe Prefferences/Display show only two choices: 6-7 steps of resolution and some color tab. No two screens, no two display to overlap, nothing for us to do. "That was the problem"! Everything is automatic.
    When I connected the HDMI cable to the Miniport into a T-bolt slot, the TV screen showed the "spiral galaxy" how Zyriab is calling it. In fact he gave me the best clue. That shows the connection is good. But where is the Mac Book image?
    You have to drag it to the right out of the Mac Book display area, and "voila!" it will continue on the TV screen. The same with the mouse pointer, push it out ofthe Mac Book display area and you see it on the TV sreen. Good image, you can keep the max resolution, etc. The sound is still on the Book's speakers. I have to figure that out.
    Thank everybody, especialy Zyriab, ne was the closest.
    High regards to everybody

  • MacBook Mini-DVI to HDMI not working on Vizio VO22LF 1080p

    I recently purchased a mini-DVI to HDMI adapter so I can hook my macbook to my Vizio 1080p LCD TV. The macbook detects the TV correctly but no matter what I do the TV never detects the macbook on the hdmi input.
    Doing some searches I saw discussion of a bug with 1080p that and a trick to get two 1920x1080 resolutions to show up in the display options but it never works for me.
    When I connect to my 42" Panasonic 720p everything works great.
    Any thoughts??

    This sounds a lot like the problem relating to an Apple disclaimer about the mini driving non-coherent displays which seems to especially affect the original G4 mini. See here under the "Video" sub-section:
    http://support.apple.com/kb/SP65
    The problem is the timing for 1680 x 1050 will often have a dot clock above 135 MHz. There are really only a couple things you can do; one is to use the VGA interface as you have been and the second is to use a program like SwitchRes X to lower the pixel clock and stay with the DVI interface. If you want to go the SwitchRes X route, download and install it (get the SwitchRes X Control Panel version and not the full version of SwitchRes X) and then write back to this thread and I can take you through the steps you need to perform. You can also get more info from this thread:

  • I connected my Macbook Pro 2012 to a 1080p monitor, and the display is cut off at the top?

    Hello,
    I have just connected my Macbook Pro to a 1080p 23' LG monitor using a Displayport to VGI adapter. However, when I use the 1080p setting, it cuts off a little bit of the top bar. When I switch to lower resolutions, it works just fine. I would rather use it at 1080p, though. Is there a way to fix this?
    Thanks,

    You may need a display adaptor but can otherwise use a non-Apple monitor.
