USB-to-DVI adapter that supports 1920 x 1080 resolution

  1. All the USB-to-VGA (or DVI) adapters I bought 2 years ago only support the resolution up to 1680 x 1050. Diamond, IOGear and SIIG.

    I am in search of one of these adapters that would support the 1920 x 1080 configuration. Came to some real disappointments.

    Bought an IOGear GUC2020DW6 USB-to-DVI adapter. On the box, it clearly said the device supports the 1920 x 1080 resolution. But it doesn't. All I got was 1680 x 1050 max. Called their technical support line. Came to an argument that the rep insisted I need to update the video device driver on my laptop to the latest version (what does that got to do with the IOGear device???) and it would work. I did as they suggested. Same thing. Resolution only 1680 x 1050. When I questioned HOW to get that 1920 x 1080 resolution to work, they just couldn't answer it but said it was a problem with my video driver. What a bag of hot air.

    Bought another make "Aluratek " AUD200F USB-to-DVI adapter. Again, the box clearly labelled that it supports the resolution of 1920 x 1080. It doesn't. The driver disk that they provided is actually the DisplayLink software - which is used by IOGear. I think this is a Chinese firm reversed-engineered the IOGear hardware and sold under their own brand name, and didn't bother to write their own driver software. The problem is the same as IOGear's. Highest resolution 1680 x 1050.

    I tried Tritton UV200 USB-to-DVI adapter. $80. This one... to my pleasant surprise, does work. Resolution 1920 x 1080.

    I gathered that Diamond BVU195 should also support the 1920 x 1080 resolution. Haven't tried this one. But since I have found one that works, I probably won't.
     
  2. That's some great info. Thanks
    What generates, and pushes the graphics bits to the display?
    Would it be possible to use multiple Tritton UV200 USB-to-DVI adapters to extend the laptop desktop across more than one display of a size and resolution you are using; additional to the laptop's?
    Does the laptop's graphics 'card' have much effect on the above?
    Does the CPU have much effect on the performance of multiple graphics displays?
     
  3. RE: What generates, and pushes the graphics bits to the display?

    The driver software generates and pushes the graphics bits through the USB port to the adapter, which converts things into DVI signals.


    RE: Would it be possible to use multiple Tritton UV200 USB-to-DVI adapters to extend the laptop desktop across more than one display of a size and resolution you are using; additional to the laptop's?

    Yap. Per their document (I haven't tried it on Tritton but other similar adapters worked okay):

    Add up to six external video card's via available USB 2.0 ports for PC users.

    RE: Does the laptop's graphics 'card' have much effect on the above?

    I don't think there is any effect at all. That's my point. It is going through the USB port and the adapter.


    RE: Does the CPU have much effect on the performance of multiple graphics displays?

    That I couldn't tell. My laptop has an i7 720QM processor. One USB graphics adapter. No performance impact noticed. One desktop has an i7 930 processor. 2 USB graphics adapters. No performance impact noticed. I suppose if the processor is older/slower (e.g. Pentium, C2D or something) it may be more noticeable.
     
  4. Could one display each attach to 1 VGA (15-pin) and 1 HDMI laptop port for extended desktop use?

    where the native screen and the two addtl screens will display three different areas of the desktop?
     
  5. These days a laptop is usually equipped with a second display port. Usually a VGA. Some: a VGA and a HDMI. However, you can only use either the VGA or the HDMI, not both at the same time, for your second display off your laptop. Then... when you add a USB-to-VGA (or USB-to-DVI) adapter, you can have a third monitor displaying the third area of your desktop. (If you have 2 USB-to-VGA adapters, you can display a fourth area of your desktop. Etc.)
     
  6. Does laptop screen size have any effect on the size/ resolution of the external displays it can drive?
    Else equal, will a 17.3" screened laptop provide advantages driving external displays that a 14" will not?
     
  7. It is not the laptop screen size that has an effect. It is the graphic chip your laptop vendor choce to use that determines what resolutions it can support. Though if you have a smaller screen laptop, they may use a chip that supports lesser resolutions. The laptop's built-in graphics chip is what drives your external monitor.

    Use this simple tool to check for yourself. On your laptop:

    Start...

    Type in "dxconfig" in the command box. That should bring up the DirectX Diagnostic Tool. Look at the "Display 1" tab. It should list your graphics chip type. Look up the specs and see what resolutions it can support.

    e.g. (enclosed)... mine (HP dv8t 1100 laptop)... HP uses NVidia GeForce GT 230M. And I looked up the specs online:

    http://www.nvidia.co.uk/object/product_geforce_gt_230m_uk.html

  8. Or if you are considering buying a new laptop, check our their technical specs (particularly: what graphics chip they use) before buying.
     
  9. When using a Tritton UV200 USB-to-DVI adapter:
    "Does laptop screen size have any effect on the size/ resolution of the external displays it can drive? Else equal, will a 17.3" screened laptop provide advantages driving external displays that a 14" will not?"
     
  10. Oh, okay. If you use a USB-to-DVI adapter, your external monitor display is driven by the graphic chip and circuitry provided by that adapter. Your laptop's screen size is irrelevant. A UV200 can drive an external monitor with 1920 x 1080 resolution whether you use a 17.3" laptop or 14" laptop.
     
  11. What limiting factors would exist - related to the max number of Tritton UV200 USB-to-DVI adapters and 1920 x 1080 resolution displays that could be driven from a laptop with three usb ports configured with three 4-Port USB 2.0 Powered Hubs or the like?

    Acceptable performance would be if charts were current to within a second of a control display running on a dedicated computer. Limiting factors CPU, Memory,...?
     
  12. Your question prompted some thoughts. I did some experiments.

    My second laptop is a 17". Resolution 1440 x 900.

    I installed the driver and plugged in the Tritton UV200 USB-to-DVI adapter and connected that to a 1920 x 1080 external monitor. It did drive the second monitor at its max resolution.

    The PrintScreen looks like this (see enclosed). Everything is a-okay.

  13. The Windows Display Manager looks like this:

  14. I think it is hard to say. You may need to test out the configuration and do your own benchmark tests and return the items if performance is not up to your standard.

    It probably depends on the complexity of the charts you are displaying. If like most of us traders all you display are price charts with a few indicators, I think the performance impact is low even if you hub the 3 adapters via one USB port. The USB display solution is definitely slower than the bus-based display card solution. But may not be that bad.

    CPU speed and memory would definitely be a relevant factor. I would venture to say that if you are not using a really old processor (such as Pentium or C2D, or the equivalents in the AMD line), you would probably be okay. Definitely 2GB memory up, 4GB the best. (Memory is affordable these days.)

    If your laptop has a "DisplayPort" output, maybe you can take a look at those "DisplayPort" 1-to-3 kind of adapter that would drive 3 external monitors from one single DisplayPort.
     
  15. I couldn't resist it. I had bought another USB-to-VGA adapter to try:

    SIIG USB-to-VGA Pro

    http://www.siig.com/it-products/usb/converters/usb-2-0-to-vga-pro.html

    The specs clearly said it supports the 1920 x 1080 resolution. This model also uses the DisplayLink driver software. And... like IOGear and AluraTek adapters (they both use DisplayLink driver), the SIIG USB-to-VGA doesn't display the 1920 x 1080 resolution either. All I got was 1680 x 1050 max. Maybe it is the driver software's fault.

    I ran out of patience to try. Too much time wasted. Just going to stick with Tritton UV200.
     
  16. Bolimomo, the amazon Reviews look decent, "Runs good at 1920x1200", what would you expect from Plugable (DisplayLink DL-195 Chipset) UGA-2K-A USB 2.0 to VGA/DVI/HDMI Adapter for Multiple Monitors up to 2048x1152 / 1920x1200 Each by Plugable Technologies? http://www.amazon.com/Plugable-Mult...iewpoints=1&sortBy=bySubmissionDateDescending

    This review is from: Plugable UGA-2K-A USB 2.0 to VGA/DVI/HDMI Adapter for Multiple Monitors up to 2048x1152 / 1920x1200 Each (DisplayLink DL-195 Chipset) (Electronics)
    Purchased to add a 3rd display on a Dell precision 4300 laptop. Runs good at 1920x1200 considering the data stream is over USB 2.0. Display is clear and was easy to setup using Windows 7 Ultimate. I use it to drive the monitor that gets the least amount of changes to the display. You may notice a slight lag compared to your other monitors and the CPU will definitely take a hit when a lot of the display area is changing. This is not an issue for me even running a 2 year old dual core system.

    As a developer the extra screen area is worth every penny. I moved my IDE's dialog windows (project nav, object, properties,etc.) over to this 3'rd display and let the code editor use the full area of the main monitor. The remaining monitor is used for test browser and other apps. I'm now thinking about adding fourth display. Since I plan to upgrade my system in the near future - I would love to see this product support USB 3.0 if gaining x10 data transfer rates would help minimize any display lag.

    The only annoyance I have is with windows and not this product. Windows will not remember the screen position so I must reset after each boot. I set this third display to the left side of the main. It on takes a seconds to change - right click, select screen resolution then drag the 3'rd monitor over to the left side. Windows will also tend to move your desktop icons over to the second monitor even though it is not set as the main monitor, so I have to drag them over to the main screen. Generally this occurs only once a day so I will put up with it to gain the extra display. """"
     
  17. Dunno. Can't say until I have tried it. Most of these adapters work equally well. But the ones that don't support higher resolutions as they advertise... you notice right away.
     
  18. Thought I'd check in here before going at it hammer and tong.

    Is anyone using Tritton SEE2 Xtreme UB200 with Windows 7?

    I just made a 1st pass at installing one out of the box and it produces an extended desktop -good. So far I'm not finding how to set the resolution to 1920x1080.

    -Shows "Mobile PC Display" and "Monitor 2" but not "Monitor 3" under "Control Panel\ Appearance and Personalization\ Display\ Screen Resolution".

    -Tritton install placed a desktop shortcut re: Display Location
     
  19. Did you mean Tritton "UV200"? If so... I am using a couple of them in Win 7.
     
  20. Indeed it is a UV. Any tips for setting screen resolution?
     
  21. Look in the System Tray.
