Hi Folks

About 4 months ago I bought a new tower just for gaming and now use my old tower for everything else.
I found this wonderful gadget a kvm switch lets you share the keyboard,mouse and monitor between the two towers and it works flawlessly you just tap the scroll lock key and the monitor blinks back and fourth between the two towers and hit the Esc key to lock it in to the one you want.
my monitor was a sylvania 20 inch crt about 5 years old and it finally went out on me so i replaced it with an acer 22" wide LCD x221.
I hooked up the new monitor and when i went to switch towers i got a (input not supported) messege from the monitor, doesnt matter what tower your switching from or to you will get this messege when trying to switch to any tower.
The switcher works if i turn off one of the towers and can use either tower i choose just cant try to switch to one, I have read alot of people getting this (input not supported) messege for many differnt reasons some its for games the fix was just using the rite refresh rate and screen size for others it was vista and acer has a driver to fix this os compatability but i have searched high and low and can not find anyone using a switcher and getting this error. I have used the recomended settings and experimented with many others with no luck. I know the problem is with the monitor though because if i hook up a crt it works just fine.
This is my first LCD monitor and i am finding that a crt isnt as picky about refresh rates and screen size as a lcd is, i am running the recomended refresh 60hrz and 1280 x 1024, i am still trying differnt color rite now im at 32 bit .
there are no drivers for the acer x221 except for the vista compatibility driver.
pc1 is a amd 1.6 with a nividia 5600 agp and pc2 is a intel duel core 1.8 with a nividia 7800 pcie.

Hi reads, welcome to the PCHF.

LCDs only support 60hrz, sometimes 75hrz, depending on the brand - but they don't need to go above 60...as the internals work differently to a CRT. The native res (1280x1024) is the maximum you'll get out of the monitor i'm affraid, as they are designed speficially for that, much like laptops...if you go above this resolution, you will need to scroll on the desktop (move the mouse to the edges of the screen to see the next part of the desktop).

It might just be the KVM that you currently have, doesn't support digital inputs, or that both computers are running out of range from your old monitor...best bet would be to boot into safe mode or reinstall video card drivers.

If this isn't the case, then i'd check to see if your monitor supports multiple inputs, and use the KVM only for your keyboard/mouse. An extra step..but an easy solution if it supports it.
