*********************************************** SMSC UFX7000 / UFX6000 Software Non Sgfx Issues release notes companion file *********************************************** This file provides information about several issues that have been observed during UFX6000 / UFX7000 testing but were found not to be caused by Sgfx software or UFX devices. 1. Nvidia drivers earlier than 305.93 (9.18.13.593) may cause RECURRING blue screen crash in notebooks when the LCD lid is open when Viewspan UFX software v4.0.50.9088 or later is installed. It has been observed in a Dell Precision M4500 Notebook with Nvida Quadro FX880 and using driver 8.16.11.8921 (original Vista SP2 inbox driver) and 8.17.12.5922 (the latest available from Windows update), that both under Windows Vista and Windows 7 the system will crash during installation of the Viewspan UFX software. subsequent reboots of the system after that produce the same result. This issue has been traced to a bug in the Nvidia driver incorrectly handling the interface that controls brightness for the internal LCD display (therefore this bug does not occur in desktops, or when the lid is closed on a notebook). Upgrading the Nvidia driver to the latest available as of the time of this release - which is 305.93 (9.18.13.593) - prevents this problem from happening. NOTES: - This issue has so far only been seen in this particular notebook and driver versions, but it could affect other notebooks with other Nvidia GPUs and same timerframe drivers. Therefore please follow: RECOMMENDATIONS TO PREVENT OR FIX THIS ISSUE: a. Upgrade the Nvidia driver to the latest available - 305.93 (9.18.13.593) or later - BEFORE installing the Viewspan UFX software. This is the same recommendation that already exists in the main release notes file under section B, IMPORTANT NOTES #2). Only after the Nvidia driver is installed go ahead with the Viewspan software installation. b. If you did not upgrade the Nvidia driver before installing Viewspan and are now experiencing crashes of the system on every boot there are a couple of ways to fix this: + Press F8 during boot and select "Last Good Known configuration". Note that this will cause the system to revert to what it thinks is the last working configuration and might revert more than just the Viewspan driver installation. Once the boot is achieved uninstall the Viewspan software or + Press F8 during boot, select "Safe Mode". After the boot completes delete the file c:\windows\system32\drivers\sgfxl32.sys in an x86 version of windows or c:\windows\system32\drivers\sgfxl64.sys in a 64 bit version of Windows. Then reboot to normal mode and uninstall the Viewspan Software. After either of the two (+) methods above, proceed with the first recommendation (a. upgrade Nvidia driver, only then install Viewspan UFX software again). 2. HP Elitebook 2570 ("Simba 3") Windows 8 x64 installation issues with Intel driver 9.17.10.2792 or later. When installing Viewspan software version 3.4.50.4262 or later in a system with this characteristics you can experience a machine freeze with black screen. You can only bring the screen back force booting the system, and the installation of Viewspan Software will not be complete. The problem was traced to a bug in this and later vailable verions (as of 8/24/2012) versions of the Intel display driver where if you disable the driver in device manager, when you later reenable it this bug is observed (system freeze with black screen). The Viewspan driver installation needs to disable and reenable the display driver in order to provide a rebootless installation experience and that is why it runs into this problem. In order to work around the problem the Viewspan driver can be installed in forced reboot mode, in which case it will not attempt to disable and reenable the display driver and just reboot the system instead. Run the installation from the command line as follows: "SgfxSetup-.exe /general /forcereboot" IMPORTANT NOTES: a. This was NOT observed under Windows 8 x86 b. The system in which this was observed appears to be a pre-production Ivy Bridge Intel chipset, this may not be observable in later Elitebook 2570 production ready machines 2. HP2159 Monitor Issues Plug/unplug USB cable, or plug/unplug HDMI output, or suspend/resume in power management cycle could show corrupted, inverted or saturated image in a USB connected monitor. This issue so far has only been observed on HP2159m monitors when using HDMI output, but was also reproduced when connecting the same monitor directly to a video port in the native display adapter. 3. GOM Player Issues a. When playing a video in GOM player, stopping and restarting it, the following can be observed during the 10 - 15 seconds following play resume: - Noticeable frame drops - Screen corruption These problems have been observed with UFX connected monitors as well as with natively connected monitors (and no Sgfx software installed in the later case). b. Noticeable frame drops occurs on Windows 7 basic mode.
