Are you using a second video card when the motherboard has an onboard video card? &nbsp;if so there may be a bios change for that.

Are you using a second video card when the motherboard has an onboard video card?  if so there may be a bios change for that.

Is it a twin port card? Try the other port. Often a twin port setup will start up in clone mode, then switch to one until desktop is extended to both.<br />

I have tried a second monitor with the same results. &nbsp;I will need to purchase a video card to bypass motherboard video port.<br />
<br />
The on board video is a single port.<br />
<br />
One issue bothers me about the system and that is the shared folder. &nbsp;It seems to me that if the problem is video only, then I should still be able to access the shared folder, but cannot.

After logging into system, display goes off. &nbsp;Only remedy is to turn system off.<br />
System is Dell Optiplex GX270 - 5+ years old<br />
<br />
1. &nbsp;Tried different profiles - same result.<br />
2. &nbsp;Uninstalled display driver - same result after reinstall.<br />
3. &nbsp;Tried safe mode with networking - same result<br />
4. &nbsp;Safe mode only - display works OK.<br />
<br />
Also, when this happens cannot access a shared folder of this system from other computer.<br />
<br />
It seems like a hardware failure to me except for the fact that it works OK in safe mode only - that seems strange to me.

Display Outage

A desktop computer is a personal computer designed for use at a single location due to its size and power requirements, usually by one person. The most common configuration has a case that houses the power supply, motherboard, disk storage (usually one or more hard disk drives and optical disc drives); a keyboard and mouse for input; and computer monitor and printer for output. The case may be oriented horizontally and placed atop a desk or vertically and placed underneath or beside a desk.

Desktops

A personal computer is a general-purpose computer whose size, capabilities and price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed systems to be used by many people, usually at the same time. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection, and through that to the Internet. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux or Macintosh OS.

A monitor or a display is an electronic visual display for computers, usually comprised of the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors used a cathode ray tube (CRT) about as deep as the screen size. They are connected to the computer via VGA, DVI, DisplayPort, Thunderbolt, LVDS or other proprietary connectors and signals.
