The players of this sad saga:
Intel HD Graphics 4600 (built into brand new ASUS desktop)
HP Monitor Model C4D33AA
Operating System: Microsoft Windows 7 (64-bit) Home Premium
ASUS desktop has HDMI & VGA connectors. As the HP monitor is DVI-D, I purchased a DVI to HDMI cable, and that worked fine... for a week.
After turning on the computer, a few initial startup screens or text can be seen as the computer starts. However, the Windows desktop never opens. Instead, I get the "Monitor Going to Sleep" message.
I have been using an old CRT monitor during this interim, via the computer's VGA connection.
I've tried many of the Internet's suggestions regarding the "Monitor Going to Sleep" problem before turning to you. Some facts:
1) The HP monitor works in Safe Mode.
2) At first, the HP monitor's status box (which briefly comes up once the monitor is turned on) reported "No signal." After fooling around with the numerous suggestions from the Internet, whatever I did enabled the DVI status to change to "Active."
3) I have updated the driver of the HP monitor.
4) I have updated the driver for my graphics card (Intel HD Graphics 4600)
5) After uninstalling the Intel driver that came with the computer, I happily discovered that the HP monitor worked with Windows' basic graphic driver. However, this driver is too basic for my needs, so even though this may promise to be a solution, it is not. Once I installed the updated Intel driver, the monitor went back to sleep. (As usual, before the desktop shows up.) THIS IS AN INDICATION THAT THE INTEL DRIVER MAY BE CAUSING THE OBSTACLE, GIVEN THAT THE MONITOR FUNCTIONED WITH THE BASIC WINDOWS DRIVER.
6) I have fooled around with the "power" settings, as well as the screen resolution. These have been part of the usual advice. The monitor itself has some settings that has not helped with solving the problem. (I've done "Factory Reset," for one.)
7) One possible solution may be to purchase a DVI-D to VGA cable, yet based on what I have subsequently read, this option is complicated and expensive, with varying results for users. Besides, I should not need to sacrifice quality.
8) "Too high a resolution set" is another bit of advice, but when I tried booting up with "Enable Low Resolution Video (640 x 480)" from Safe Mode, that made no difference.
9) Another bit of advice is to update the BIOS, but I don't think that is the problem given that the computer is so new. (Besides, I have a fear regarding BIOS changes.) Yet another bit of advice is to jiggle around the RAM, but ASUS voids their warranty if the computer case is opened.
HP has a page that addresses this problem; the section under the heading, "Startup screens display, but the message opens before the Windows desktop opens" is relevant to my situation:
Nothing from that page worked. The conclusion of the section reads:
"If Windows desktop opens in safe mode, the issue is related to the display resolution being used in normal operation (not safe mode). You should set the normal display resolution on the computer to the native display resolution of the monitor... If the native resolution setting is not available as a selection in Windows, you can temporarily use 1024 x 768 to complete these steps... Updating the graphics driver can provide more display resolutions to Windows; possibly including the native display resolution for the monitor."
1024 x 768 has been my only option, from Safe Mode. (1600 x 900 is the HP monitor's native resolution.) I cannot set the resolution to 1600 x 900 from the VGA-supported CRT monitor I've been using, nor even determine whether 1600 x 900 has been made available through the updated Intel driver, because Windows' maximum screen resolution made available through the CRT monitor is 1280 x 1024.
Boy, this problem has been unreasonably time-consuming..I hope you will be able to help me solve it.
Thank you very much.
