Solve : GeForce GT730 & Linksys KVM - Screensize swells and goes off the screen? |
|
Answer» Recently I started using 2 computers at the same time and noticed that if I switch the KVM from PC1 to PC2 and back I have no problems. But if I switch from PC1 to PC2 and say I am at PC2 for 30 minutes and then I switch back to PC1 I come back to the screen swelled and the mouse pointer is able to go off the screen into where you cant see to select things. Screen resolution I am using is 1280 x 1024 and when I come back to my screen its changed itself to 1024x768 and sometimes 640x480. I looked into nVidia and Windows 7 64-bit display properties to try to figure out how to shut off this feature where it appears that after a period of time the it polls the hardware and then I guess the KVM syncs up with the GT 730 on a lower resolution. Does it exhibit this behaviour if the KVM is out of the loop ? ? Connected directly to a monitor here is another thing to share and it might be related and might not be. If the computer is left running with monitor on no problems at all. However if I have something running and I shut the monitor off for the night to reduce ELECTRIC waste and turn monitor on the next morning the display is black and no signal. Computer running still and not crashed, but it doesnt REESTABLISH the video signal to the display. Additionally this GT 730 video card requires a display to be on and active at boot or else VGA wont function. Tested both with and without KVM, if I boot the computer up and its not the focus of the KVM or the monitor is off and I push the power button and take too long to turn the monitor on, the window of opportunity for the video card to detect which port is in use for video is gone. I then have to hold the power button in to force shutdown the computer and then turn it on again to have it see which port is active for display. I dont have a HDMI or DVI type of monitor to see if the video defaults to one of the other ports. I am still getting by with flat screen square 17" and 19" flat screens as for I dont like how the older games play on the wide screen displays so i like the square ratios so that I down have a short fat character running around or a car thats wide and lowrider. The Radeon HD5450 I had prior had no problems at all. So thats why I dont believe it has anything to do with Windows 7 64-bit and has all to do with this GT 730 somehow. I havent tested yet to see exactly how much time goes by before it decides to wig out when away from being the focus. But I suppose I could test at 5, 10, 15, 20, 25, 30 minute interval to see exactly how long it needs to be away when it has some sort of hardware poll in which it decides to change itself and act up. GT 730 otherwise runs flawless, so anyone using it in a system that doesnt have idle time without dedicated video would probably never have this problem. Additionally maybe having it connected as dual-video out might fix this too. I do have 2 displays and could set that up as a test and have 1 of the 2 displays switched with the other active always to tickle the GT 730s hardware sense requirement. But the difference between these 2 issues ( KVM vs Monitor Off but still connected physically) are that one makes the display disappear completely and the other a sizing issue when away. Update on this: Last night I tried in 5, 10, 15, 20, 25, 30 minute then 1 hour increment to have the KVM switched to the other computer and then go back to see if the first computers display ACTED up and I couldnt get it to act up when I wanted to in order to then test again at the same interval to try to get more insight as to how long before it wigs out. Will update again if I have anything new to report on this issue.It's like tryin to get your car to make that noise when you take it to the shop... Quote It's like tryin to get your car to make that noise when you take it to the shop... hehe very true... Its almost like its hiding from me like a GREMLIN inside though as for it was happening very frequently and then I go in to hunt it down and its now in hiding. There should be something done in a specific order or length of time that will make it repeatable given the same conditions. I guess each time it happens now I will be writing down about how long I was away from it and what was running.As your mechanic i'm still gonna have to bill you for diagnosis.... Quote As your mechanic i'm still gonna have to bill you for diagnosis.... Monitors report their display information to the PC, max resolution, refresh rate, etc. What it sounds like is the KVM isn't reporting the same information as the Monitor itself to the PC that isn't being passed through. The delay/interval would likely be due to how frequently that information is being polled; or perhaps the KVM keeps reporting the same info to a PC when asked but has a "sleep" timeout where it makes the disconnected PC think the monitor is asleep, or maybe it disconnects it or does something weird. For what it's worth You don't need a KMV thing anymore. http://www.makeuseof.com/tag/why-you-no-longer-need-a-kvm-switch-for-your-multi-pc-setup/ Quote In this article, I’m going to cover three of the best applications available that will let you use two computers with a single mouse and keyboard, without very much hassle at all. That requirement is important because it actually forced me to shy away from reviewing Synergy, after I spent nearly an hour trying to get it working on my two laptops without much luck at all. You’ll see how the programs I review below take under a couple of minutes to install, and barely five minutes to set up before you’re up and running. |
