Can't remove lock logo on screen

Sleep mode is a convenient power-saving feature used on both laptops and desktop computers. This feature powers down hard disks, monitors, wireless devices and any other power-consuming peripherals without turning the unit completely off and necessitating a reboot. Sleep mode can prevent battery drain if using a laptop or mobile device while away from the power supply. This mode is useful when quick access to a computer is needed, but can be irritating if the sleep mode takes a long time to come back from. It is simple to turn sleep mode off, based on the operating system being used.

Go to the "Start" button, then click on "Control Panel." In the control panel screen, click "System and Maintenance," then click on "Power Options." This brings you to the "Select a power plan" page. From the "Select a power plan" page, select the option that says "Change plan settings." This changes the settings on the currently selected plan. Select the "Change advanced power settings" option. Click "Sleep" and then click on "Sleep After" to expand it. If using a laptop or mobile PC, click "On battery" and "Plugged in," then select the "Never" option. This turns off sleep mode for both battery and AC use. If you are using a desktop computer, click "Setting," click the arrow and then click "Never" to turn off sleep mode. Click "OK," then click "Save changes" to save the modification. b> Turning Off Sleep Mode - Mac OS b> Click on the Apple logo at the upper left corner of the screen to open the menu and select the "System Preferences" option. From the "System Preferences" screen, click on "Energy Saver." If you are using a desktop, select "Power Adapter" in the top drop-down menu. In the second drop-down menu, select "Custom." Highlight the "Sleep" tab, then adjust the top slider to the far right, marked "Never." I f you wish the display to stay on, adjust the bottom slider to "Never." Click the red button on the upper left side of the "Energy Saver" screen. If you are using a mobile product or laptop, follow step 2 and select "Battery" from the top drop-down menu. Repeat step 3 to change the settings for battery use. Hope this helps.

I believe the Dell logo is hard-coded for the Startup, but you can change the Wallpaper form the Dell logo, to an image of your choice:

From the Setup Menu, or Others Menu, you can go into:
SCREEN SETTINGS—Select and press checkmark to activate screen settings. The screen
settings menu consists of the following options:

CAPTURE SCREEN—Select and press checkmark to capture the screen display, the following message appears on the screen.

NOTE: To capture a full image, ensure the input signal that is connected to the projector is 1280 x 800 resolution.

SCREEN—Select Dell to use the Dell logo as wallpaper. Select Captured to set the captured image as wallpaper.

RESET—Select and press to delete the captured picture and set back to the default setting.

More information available on the Manual here: http://support.dell.com/support/edocs/acc/4310WX/en/ug/pdf/4310WX_en.pdf

Restart your computer in Safe Mode
(or reconnect your previous monitor).

Set the screen-resolution to 800 by 600 at 60 Hertz.
Shutdown, connect the new monitor, and restart, and your Soyo monitor will be able to display something, using these "NOT-out-of-range" values.

Try changing the resolution to 1024-by-768, or 1280-by-1024,
and "test' these values, to see what values are "in-range" for your new monitor.

Try reseting it. If that does not resolve the issue, put it into disc mode and restore again. If these steps do not help please let me know.
