This file is also used by Gateway and could be used by others in same way. In my case it is specifically for my Gateway widescreen flatpanel monitor. It is part of their EZ-Tune software for the monitor. This program is continually monitoring the monitor for any changes in settings. If settings are changed away from 'ideal', the program interupts with a message box and instructions/options. Can be removed through add/remove programs. Not necessary for continued operation of any computer part, program or device. Located in c:\Program Files\Gateway\EzTune. File size = 271,360 bytes.

I have an Emachines T2542 running WindowsXP with SP3. The NVIDIA GeForce 8400 GS card is the PCI version. All was well after the installation until I logged out from one user account and logged into another user account. After the second login into the other account, the login appeared to go through the normal sequence of loading programs from the Startup folder (wallpaper appeared, desktop appeared, desktop icons appeared, display looked sharp and at the desired aspect ratio) when the screen went black, began to redisplay the desktop, then WHAM! A blue screen and sudden reboot.

It's appeared with my new Philips wide screen monitor. When screen slows right down it is using 98% of memory resources. If I force it to terminate in Tasks all works ok.
Suddenly got an Avast error about possible danger, but this file must've been on my hard drive for years as part of my HP/My Display. Opened it in the "Sandbox" just to make sure.
