<p></p> <p><b>New page</b></p><div>= Video Issues = <br /> <br /> Occasionally Untangle can not correctly detect video card/monitor settings to successfully display onto the monitor. This can happen in several ways:<br /> <br /> * The monitor flashes and then displays a black screen with a message or login prompt<br /> * The monitor just displays noise after the bootup is complete<br /> * The monitor displays correctly but the screen is much too big requiring scrolling with the mouse.<br /> <br /> [[Image:MonitorProblem.jpeg|300px|center|Video Problem]]<br /> <br /> Things to try:<br /> <br /> * Restart the server and select a different boot mode in the bootup kernel selection menu.<br /> * Try various BIOS settings that may affect video.<br /> * Try another monitor, and reboot after switching. The monitor should be plugged in before powering on Untangle.<br /> * If you are using a KVM (keyboard-video-monitor switch), remove it and connected the peripherals directly.<br /> * Try another video card.<br /> * Re-burn the CD/ISO at a slower speed, or re-create the USB/IMG, and reinstall.<br /> <br /> <br /> Also note that changing resolutions is supported, but can sometimes lead to issues. If this is the case reboot the server in Video Safe Mode.</div>
