    John, thank for reply.

    i want to know:

    a)is this the normal behavior?
    if you connect a mac computer, and press the "shift + command + 4" (screenshot), what happen?
    lost the key.

    b) is the normal behavior listen noise when move the mouse?

    c) slow move of the mose?

    if i replace the unit, the new unit will work well?

    by Monoprice Administrator

    That isn't normal behavior as its suppose to be fluid. It also shouldn't make noise when you move the mouse. While I can't guarantee it will work properly when you receive the replacement, you won't know when you try. Please let me know if you want to continue. Thank you!

    Poor quality

    • Corey,
    •  Denver, CO 
    • 2/27/2014 1:04:19 PM

    Pros: Occasionally works

    Cons: Mostly doesn't work

    I like the idea of this product. But just now it decided that keys 1, 2 and 3 on my keyboard should be ignored. I had to reset the unit by unplugging all USB and DVI cables and the power cord. It's only a matter of time before a single press of, say, the i key turns into iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii. This happens all the time. Keystrokes are repeatedly dropped or repeated ad infinitum. I'd like to believe a replacement would help the problem, but I've come to expect this of KVM switches. I don't know why it's so hard to create one that works.

    TLDR does not work. Do not buy.

    Hello Corey,

    Also, if you no longer have a need for the KVM switch, I can help setup an RMA for a return. If you would like me to proceed with the RMA, just let me know and I can get it started right away. Sorry again for the trouble and hope this helps!

    Hi Jonathan,
    Thank you for the reply to my review. I would find a KVM switch useful. If you believe that the problem's I've been having are due to a faulty unit I'd be pleased with a replacement. I would have to request an advance replacement, as I don't want to go through the immense hassle of re-cabling my desk twice. I'd like to point out that this device was actually purchased through my employer, the University of Colorado, and that we do a lot of business with Monoprice.
    Thank you,

    Corey Keasling

    Wish it just worked !

    • JD,

    Pros: Switches quickly (big plus)
    Supports greater than 1920x1080 (big plus)
    Tripple ports
    Long cables
    USB and PS2 support for IO devices (big plus)
    Well constructed (big plus)

    Cons: Issues with keyboard tossing multiple characters i.e. typpppppppppppying a word runs one character
    Mouse issues - mainly on my Win7 Toshiba laptop - just stops working ! Requires multiple reconnections
    Lifetime warranty on the cables ?? But no listed duration for the switch itself.
    Optional power supply for the device - but not included and not available

    I really wanted this switch to work the way my old VGA no-name brand worked ... but I've had a bunch of issues. Reading through the other reviews, I see that I'm not alone. Lots of others are reporting similar issues that I'm having ... the switch repeating multiple characters when typing, and mouse completely dropping in Windows 7. I can deal with the sporadic multiple characters when I type, but dropping the mouse connection multiple times during the day is a show stopper.

    I have a VGA switch that I bought years ago at Frys (a two port with integrated cables and sound) that has just worked ... and for years. I expected this DVI switch from Monoprice to do the same ... just work! But the product has lots of issues. For over $100, I expected more from this product. The product's performance is disappointing, and I'm now forced to look for a replacement. Recently, the switch has been just dropped mouse functions in Windows 7. I now have to have a 2nd mouse connected directly to the Windows 7 machine to keep the switch working (seems to help but not a 100% effective solution).

    I am using this switch to handle my main Asus 23" DVI connected display to connect to my work laptop (win7) and my Mac mini. I continue to use the old VGA switch to handle switching the 2nd display between the same two machines.

    Based on my experience, and the reviews of others, I can NOT recommend this product to anyone ... look elsewhere. This experience sadly tarnished my view of Monoprice and their products.

    Day 1 Working Thus Far

    • Tom J,
    •  Richfield, MN 
    • 4/29/2013 3:43:21 PM

    Pros: -Feature Rich
    -Good Build Quality
    -USB Pass-through works good
    -Audio Support, no issues here
    -Good video quality, no issues here

    Cons: -Keys being missed as typing (huge issue)
    -No support for devices like Logitech keyboards (wireless) or any wireless unified mouse. The mouse works but no support for extra features like other buttons as it is recognized simply as a usb mouse on Mac/Windows and not logitech mouse.

    On the first day I noticed keys missing when I typed. This is of course a huge issue an noted by many other users of this device. If there are any keys missing in this short review you can be assured it is due to the deviceit self (no space there because it was missed!). I think I'll attempt to RMA the device but I really don't want to have to disconnect all my cables again as it took time to get things all set up.

    Hello Tom,

    Thank you for your review and my apologies for the issues you have experienced with PID 3408. Unfortunately, it sounds like you may have received a defective product.
    Now if you haven't done so already, I can help setup an RMA for a replacement. If you would like me to proceed with the RMA, all I would need is the order # this KVM switch is under. Sorry again for the trouble and thanks in advance!

    Great Equioment

    Pros: Great equipment. Well designed. Clear specs and easy to find products on web site.

    Cons: No

    Have used many Monoprice cables, adapters and KVM switches for a number or years. Have had no problems. This DVI switch includes audio switching, a huge addition. Monoprice with great pricing and a large selection is my first choice.
