    Compatibility issues with HDCP and Gateway 24 LCD
    I bought this to share a Gateway 24 LCD, model FHD2401, between multiple computers using nVidia video cards, 8600GT, 9500GT, and 980GT, with their DVI outputs.

    At first, everything appeared to work fine, including the Cyberlink Blu-ray test, which tests for HDCP compliance.

    Unfortunately, things went bad after I powered down one PC. The monitor then went to DPMS sleep mode, as it should. Then, I switched to another PC which was live on the DVI switch.

    At that point, the Gateway monitor woke up, but instead of displaying the other PCs picture, it went into a state of displaying garbage - snow. This is typical in cases of HDCP handshake failures. This state could only be cleared by yanking the power cord out of the Gateway monitor, and putting it back in. Then, the picture came ack. Obviously this wasnt an acceptable thing for me to do each time after I would power down my PCs.

    I know this problem is with the switch because it doesnt occur with another DVI switch from Gefen - which unfortunately costs 7 times the price of this one. I really wish I could use the Monoprice switch but I cant live with this compatibility problem and having to yank the power cord off the monitor, so I had to return it.

    this switch is AWESOME !
    This is a great DVI switcher ! I hooked it up to my HP Widescreen that uses 1680x1050 screen resolution and it switches wonderfully! I was worried because the tech specs said 1600 max so I wasnt sure what those 80 pixels were gonna do...

    Piece of cake to setup and now I can hook 4 devices to this great single monitor at its highest resolution.

    Remember to have the monitor turned off (not sleeping) prior to install or the box and monitor wont handshake or just hook it up and turn your monitor off then on with the box powered so they handshake.

    Cant say enough about the switcher! it does the job and its at a great price !

    thanks Monoprice !

    Great Switch
    Great product, Im using it to share my LCD monitor between my PC and PS3 which works great.

    This review would be a 10 only for the size of the switch - its very solid but takes up a lot of desk space , the is a small complaint really.

    I love it and would buy it again.

    Supports higher res
    Just wanted to add that Im running 1920x1200 without any problems. Im ordering another one for my other monitor. Now if only there was a dual DVI version(however, ordering two here is cheaper than any dual DVI switcher Ive found).

    I would agree that the flashing light is slightly bothersome (hence the 9/10). The box is a little wider than desired but I suspect that is because it can also be rack mounted.

    This switcher does what its supposed to do, and does it well.

    I bought it to share my monitor between my PC and PS3, and it allows me to do just that.

    Downsides, though... the LED lights are ALWAYS lit and/or flashing... even when the console/PC and monitor are powered off.

    When the video sender and receiver are both connected and powered on, that input LED has a constant green along with a flashing red which is somewhat distracting.

    When the components are all turned off, the switchers 4 LEDs flash red continuously, which is extremely distracting.

    Ive resorted to covering the LEDs about 99% with black electricians tape, just leaving a sliver at the top of the LEDs exposed to allow me to see green on the LED of the selected input.

    Otherwise, the only option (to avoid the distracting lights at all times) is to unplug the switchers power cable when not in use. And even then... very oddly... after unplugging the power cable, the LEDs continue to operate for some time. o_O (no idea how thats possible... its like the box stores energy somehow)

    Bottom line... very functional, easy to use, works well... but the details, and aesthetics, are problematic.

    Almost a good implementation
    I wanted to love this switch. The way it is, the DVI switch is barely adequate. The automated seek of the next active port is badly implemented (see cons) and really not useful even if it worked perfectly. In order to switch between two active ports, I manually have to push a button which is just fine. However, the automation tries to override my choice which is just stupid.

    PROS: Actually successfully switches between four DVI-D sources . . . eventually. You would not believe how hard this seems to be to do unless you need a KVM switch. Monoprice has somewhat succeeded with this function. See cons.

    CONS: The constantly blinking red "selected" light is just stupid. Nobody out of the design department thinks this is a good idea.

    The automation that seeks the next active port is a pain. The user should be able to switch this off. When I manually switch the device to a specific port, the switch should go there and stay. Instead, it will sometimes flash on the new port and go back to the original port. Or it will blink all four lights and switch aimlessly back and forth between the one I selected and nothing. I can eventually get it to do what I want but I should not have to fight the automation that frankly is not helpful anyway.
