How fast is the switch over from source a to b? milliseconds, seconds? is there noticeable display flicker or blackness?

There's no spec on the switch over speed. From my experience, I would describe that there is a blink between the switch.
1058032
A few seconds. There may be a millisecond pause/stutter with whatever you are doing on the b machine when it connects.

I never noticed any discernible delay. maybe a couple of milliseconds. I use two monitors on A and only one on b. And sometime the a computer monitor might power down while using the other box so it would have to come back up when switched. Since I am away from my desk regularly I do not want to turn that feature off.

I don't recall any significant or annoying delay. Maybe milliseconds, certainly not a second or more. Once switched, no display anomalys, BUT the computer that is connected/switched in upon boot up will connect at better resolution than the computer which is not, so one had a higher resolution than the other upon switching back and forth. Can't recall, but can probably set the 2nd computer resolution after switching.

I would say a second at the most for duration. As for display flicker, I would say it resembles "slideshow" change.

I have 3 plasmas (will have 4 soon). My oldest is 5 years old (480p). If I go to a blue screen I can see a slight burn from [MUTE] flashing in the same spot. With normal content on the screen it is not noticeable at all. The newer panels are so much more advanced and burn-in or IR is a thing of the past. Turn on the "pixel shift" and don't worry. Just don't fall asleep with a still image on any technology.

After sitting a while, there is a very short delay -- it felt like 1/8 of a second. When I turned the switch on, off, and on again, there was no delay.

No flicker at all for me....I used it to switch between my older Tivo and my DVD player. Recently, I upgraded my Tivo to Tivo HD, so I now have an HDMI cable for it and only have my DVD player on the switchbox. I never had any trouble with my StarTech switchbox. It's a good investment if you have non-HD components that you need to add into your configuration with your TV.

30 seconds for the computer to turn on. Full brightness is very fast. The problem is waking up your computer to send a signal to the monitor isn't stable. Sometimes I'll get lucky and it'll work within seconds. Other times, I had to lift my laptop display. The thing is there are no drivers, which apple or acer have to address. Other than that the monitor is good.Does anyone besides me run this monitor on a mac?

There is minimal delay between turning on unit and sound output - seconds at most. I've had no trouble with this unit since it's purchase in August.

I can't answer that question right now. I do know that my unit is dark and does not emit any disturbing display light whatsoever.

the HDMI response time is about 4-6 seconds ,it is normal for blue screen in a while ,please confirm you select correct input (on the front case with different input buttons ) ,thanks. VIVITEQ INC

Yes, there is a brief delay but that's not unusual though. The time it takes for electronic devices make the so-called "electronic handshake" is normal for just about all switching devices.The length of the delay depends on the individual devices, some take longer than others, but in general I'd say between five and eight seconds. For the low price, this switch has been just great for me.

um im not sure what you mean by refresh rate. like how fast it turn on? pretty quick. be a little more pacific maybe i can answer your question

I haven't tried it without a monitor; not sure why you'd want to. It switches immediately, although the Ctl-Alt-4 doesn't always work, sometimes I have to push the KVM button.

It switches pretty quick, but as to not using the monitor. What are you trying to accomplish? This switch is so that you can use one monitor with two different computers, so not using a monitor does not really make sense, unless you are thinking of an HDMI plug in, instead of the VGA, the switch does not have an HDMI.

If I turn the brightness down far enough, then PWM flicker does show up, but I run it at 100% brightness and haven't had any problems. From what I have read, running the brightness at 100% eliminates the use of PWM. People suggest using software to adjust brightness and leave this at max.Mine has 5 buttons on the bottom of the monitor, from left to right, Bright+, Bright-, Vol+, Vol-. There is no display showing you what setting you are at though.

I actually have the same question. I can say that for a while I was using a HDMI switch and didn't have any difference in lag with it or a straight connection so hopefully this will be the same.

I'm getting a lot more than the other answers so far. I keep the display a couple ticks below maximum brightness most of the time, which helps, but I get a good eight hours.

Yes, there is a slight delay (at least with my TV). As with most TV's, switch or not, there is a delay between switching to the input, and the input displaying on the TV.

I can't say. I'm one Win7 and one XP, with one VGA and one DVI monitor. Sometimes the mouse is very choppy after switching, but it seems to resolve itself quickly. Just a short, minor nuisance. It's not perfect, but I'm not unhappy with it. Call the mfr with your question. They were helpful and knowledgeable when I called.
