KVM switch + Windows 7 creates monitor switching nightmare

hi

aten(iogear) give me response about this issue not long ago.

Dear Valued Customer:

Thank for your feedback.

CS1762 does't support Video DynaSync technique.(CS1782 is the new version and support Video DynaSync)

PC can't detect Monitor's EDID when PC does't connect to the active port.

PC will use its default EDID setting(1024x768).

Thus when you switch to the other PC.

The PC will use the default resolution.

Because it is the default spec of CS1762.

If you need the new technique of Video DynaSync(such as CS1782).

You can purchase CS1782 from your local dealer.

Sincerely,

Albert.Tsai

personally very disappointed because it is not clearly stated on website and the retailer just sell the old model as new. for USD 170...

feeling got cheated.

there are only 2 solution

1. stress iogear/aten to come out new frimware
2. throw the kvm away and get a new one.

This might also be Nvidia's problem.

I am using Windows XP and everything went fine. Until i upgraded to Nvidia's driver 197.45 XP 32-bit The display will switch to 1024x768 every time i make a kvm switch and i have to manually switch back at windows's display settings (Nvidia just won't recognize the available resolution until i manually set the resolution!).

I’ve been following this thread for several months and have been amused, angered and dumbfounded all at the same time. I’ve Googled this issue, read all the “fixes” and tried several different KVM switches myself with no luck. As for the VNC and Kavoom suggestions, these aren’t fixes, but very poor work-arounds.  Anyone using graphic software or gaming will find the lag completely unacceptable.

As for Micro$ofts response, telling your consumers to look over a developers validation document is like auto manufacturer telling its’ customers to study the blueprints of their engine design because they decided to change the type of fuel that can be used in your car and you as a consumer are stuck with a vehicle that no longer works, just because Ford/Chevy/whoever says so. It’s not our fault; it’s the oil companies, even though the fuel works in all our previous models and every other car manufacturer’s models.

Whether it’s DVI or analog is irrelevant. It doesn’t work for either, and that’s the bottom line. I’ve been reduced to buying an emulator from ConnectPro as I have only one Win 7 box and it just doesn’t make sense to buy a $120 KVM switch when a $45 adapter will relieve my problem. It’s a matter of M$ having me by the balls and if I want my system to work, I have to take matters into my own hands and do the least costly fix I can find. It’s bullshite, but I have no other choice. Yes, I have a Mac and an Ubuntu box, but I need to work in my Win 7 box. I can’t leave M$, it’s my job and how I make my living.

In my case I have a Win 7 box, which started out as a Vista box and then I have two other systems connected to the KVM; an Ubuntu and a XP Pro box. As with many other posters, everything worked fine until the Vista box was upgraded to Win 7. I’ve tried a Belkin switch and two different models of IOGear units and always get the same Generic PNP display when going through the switch.

By the balls my friends, by the balls…

It seems that I'm having similar problem. It is not exactly a KVM issue, but if you treat AV Receiver as KVM it gets common. My PC is connected to 42" plasma display through HDMI using AV Receiver and antother display is 22" LCD connected through DVI.

I'm having hard times with this setup.I cannot boot to my Windows session because I always get my login screen on the 42" display which is .... powered off! I have two solutions for that:

• turn on the display just for a second, login screen gets back to 22" LCD, and then turn it off to resume work.Sometimes it works, sometimes desktop will switch to not used and powered off display again. It depends on how fast I will turn the display off.
• disconnect HDMI display physically.

I've tried different combinations of AVR and windows 7 multiple displays  setups. No success. I'm using GF9800 card with one HDMI and one DVI outputs.

I'm unable to change which display is which under setup. My 42" TV is always detected as "2" and LCD as "1" no matter how they are set using "Primary/Secondary" switch. My LCD is set as primary but gets "2" during detection....

Is there any solution for that? I'd like to disable autodetect of displays or anyhow set my monitor setup as "static".

Just to be clear here: Most people specifically using DVI KVMs will never be happy to just go out and buy a VGA KVM instead. DVI KVMs are clearly targeted at users who will NOT accept a strong loss of picture quality due to an analog connection. People who do graphics work, photo editing or any other kind of work that relies on a precise and undistorted image will only accept a digital connexion to their monitor. What's the point in having a 800$+ monitor (some in the thousands of dollars) if you feed a crappy signal to it?!

So even if some of you guys would gladly settle for a VGA switch, I know I (and many others) won't.

Imagine if their was only two cable companies: Microsoft Cable and Apple Cable. The latter would have very beautiful and expensive set-tops but be lacking in the programming department. So most people would sign up with Microsoft Cable instead. After all, their cheap and plain looking set-tops would do the job... and most people are more interested in the programming anyway.

Now, imagine that MS Cable just convinced you to buy into their newest, upgraded, redesigned service. But the minute they switch you to this pricey upgrade you discover that it in fact forces you back to analog TV! And when you complain about it, they simply say that they knew it would make your set-top inoperable from the start... but that they were the ones to decide what was best for you... and that they could always sell you a new set-top if you now wanted to go back to digital! :+o

So that's the way to progress in a monopolistic environment: They create a new product, your choice is to buy it or keep the old one... and if you choose the new one, you may or may not be able to use your computer the way you did before. Just live with it dude.

So now I feel like I've just given MS money to pay part of its latest Billion dollars fine to the EU for mopolistic behavior... and ended up with a product that renders some of my hardware unusable in exchange. Thanks MS! :+0
