Hi, I'm new to the board and this is my first post. I really like win 7, I think it's steady and reliable. But I have a kinda huge problem. Whenever my display goes to sleep, switch my KVM to my other computer or turn the monitor off while windows 7 is running, the monitor will not wake up. In fact, the monitor will display "No Input Signal" and then "Monitor going to sleep". No matter how much I move the mouse, click the mouse or tap keys on my keyboard, it just won't come back up. The only way to get my monitor to work again is to restart my computer. I'm running Win 7 x64 RC. I have an ATI Radeon x800, 256mb, PCI-x 16 video adapter and an HP w2207 HDMI monitor. I've checked ATI's website for drivers and they do not have a win 7 driver for the x800, but they do for some of their other display adapters. So I downloaded the ATI Catalyst/Driver for Vista x64. The file name is 9-3_vista64_win7_64_dd_ccc_wdm_enu.exe. Since they put "win7_64" in the file name, I assumed this should work. But there was an error during the install and the driver would not load, so I dl'd the driver only and installed through Device Manager and this time it installed. After a restart, the problem still persists. I hope there's a solution.
