    I am planning to get an 29" Ultrawide 21:9 monitor, running at a resolution of 2560 X 1080. My laptop is a Sony Vaio VPCEB24EN, almost 4 years old running with an ATI Mobility Radeon 5145 - 512 MB Graphics Card. Not sure if other specs matter but if you are curious - Intel i3 2.3GHz, 1 TB HDD, 6 GB Ram and 1366x768 native display resolution. It has a VGA port and an HDMI which I frequently use with a 1920x1080 display. My question is - will my laptop be able to utilize the full screen space of the 2560 pixels of the monitor and should HDMI be good for it. The laptop will not be used for gaming, mainly for movies and browsing, slight photoshop usage with maybe 20 layers at max. Thanks in advance for any help.

    Technical specifications

    The Sony VAIO VPCEB24EN comes with a ATI Mobility Radeon 5145 graphic card with 512 MB of dedicated RAM. You can confirm that by using a program such as GPU-Z.

    Here's an excerpt from the official specifications:

    • One integrated LVDS display output

      • Integrated LVDS display outputs for embedded panels
      • Supports 18- and 24-bit digital displays at all resolutions up to 1920x1200 (Dual-Channel LVDS)

    • Two integrated DVI display outputs

      • Supports 18-, 24-, and 30-bit digital displays at all resolutions up to 1920x1200 (single-link DVI) or 2560x1600 (dual-link DVI)2
      • Supports 18-, 24-, and 30-bit digital displays at all resolutions up to 1920x1200 (single-link DVI only)2
      • Each includes a dual-link HDCP encoder with on-chip key storage for high resolution playback of protected content3

    • One integrated 400 MHz 30-bit RAMDACs

      • Supporting analog displays connected by VGA at all resolutions up to 2048x15362

    • DisplayPort™ output support

      • Supports 24- and 30-bit displays at all resolutions up to 2560x16002
      • Integrated HD audio controller with up to 2 channel 48 KHz stereo or multi-channel (7.1) AC3 enabling a plug-and-play cable-less audio solution4

    • HDMI output support

      • Supports all display resolutions up to 1920x10802
      • Integrated HD audio controller with up to 2 channel 48 KHz stereo or multi-channel (7.1) AC3 enabling a plug-and-play cable-less audio solution4

    2. Some custom resolutions require user configuration.
    3. Playing HDCP content requires additional HDCP ready components, including but not limited to an HDCP ready monitor, Blu-ray or HD DVD disc drive, multimedia application and computer operating system.
    4. Subject to digital rights management limitations; maximum supported audio stream bandwidth is 6.144 Mbps.

    Additional information

    The AMD ATI Mobility Radeon HD 5145 is a renamed Mobility Radeon HD 4570 with slightly higher clock rates. Therefore (despite the 5000 series name), the card supports only DirectX 10.1 and is still produced in 55nm.

    Quoting the fine print found on the AMD website (emphasis mine):

    Performance, technologies and features listed above can vary with specific notebook implementations. Please consult with Notebook vendor for a complete list of supported features.

    ATI Radeon™ HD graphics chips have numerous features integrated into the processor itself (e.g., HDCP, HDMI, etc.). Third parties manufacturing products based on, or incorporating ATI Radeon HD graphics chips, may choose to enable some or all of these features.

    Display output

    Despite the fact that the graphic card supports resolutions up to 2560x1600 through the DVI (dual link) or DisplayPort interface, the laptop only provides a HDMI port and a legacy VGA port. It's logical to assume Sony didn't implement the other ports at all, thus the motherboard lacks the necessary hardware logic.

    If you were to use a passive HDMI to DVI dual link adapter, the entire HDMI signal would transmitted through a single link of the DVI connector, and not both. A single link DVI supports resolutions up to 1920x1200; in order to get higher resolutions you would need a powered, active solution to upscale the input signal.

    Your graphics card supports resolutions upto 2560x1600. However, I couldn't find a spec sheet for the product on AMD's website so I can't be sure.

    multiple monitors - Can my laptop run dual 1080p (Sony Vaio - Nvidia 330M)
  • Charlino

    I am looking to buy a monitor to setup dual monitors for my laptop and was wondering if my laptop could handle 2 x 1080p.

    I have a Sony Vaio VPCF116FG which has a Nvidia GeForce 330M chip and 1GB dedicated graphics memory. The laptop also has a Intel® Core™ i7-720QM Processor (1.60 GHz with Turbo Boost up to 2.80 GHz) but I don't know if that's relevant(?).

    The laptop screen has a native resolution of 1080p (1920 x 1080) so I'll be looking at buying a external monitor with 1080p to connect up using a HDMI cable.

    So, the question is, will my laptop be able to handle it's own 1080p screen AND an external 1080p screen?

    The laptop has an HDMI In/Out Output Connector, which is only designed for the input/output of digital video/audio.

    Make sure the monitor can receive HDMI input and it will be able to act as your second monitor.

    You'll also need to ensure you have the latest motherboard/video drivers from Sony/Nvidia, which will provide the GUI to manage extending your desktop onto a seconday monitor.

    There's only one way to find out and that's to actually do it.

    It works. Good times.
