Hello Kezo,

There are few steps that I would suggest in order to isolate the issue.

-- Perform the monitor self-test.
Disconnect the VGA cable check if you get any error message.
If the test fails the monitor needs to replaced. If the test passes, follow the next step.

-- Check in BIOS if you get Display.
To enter System BIOS, Restart the computer, keep tapping F2 at the Dell logo screen. It would enter the system BIOS. Check if you get Display and let me know.

-- Please try with a different monitor cable if possible.

Write back to us with the results I would be glad to assist further.

Hello, I have a laptop, no vga cable.
There is not any display option in my Bios
before formatting was all ok
I've tried to update graphic e monitor driver but the problem has not resolved
I post a picture example when I create a gradient in photoshop with dithering enable

Hello Kezo,

In order to assist you further, I would like to know how is the display when you are watching any video. Please try playing a video and check the functionality of the display.

-- Try running the LCD Built-In Self-Test (BIST) 
-- Also try connecting an external monitor to the laptop and check the functionality. These steps would help us in isolating the issue. 

Please write back with results.  

hello allan,

I can see videos propertly

LCD test

1:  I've tried the lcd built test pressing D+ power button. It was not like the video tutorial, there where a lot of distorded white and black stripes, to much noise.

2: I've tried to launch diagnostic test from the boot,

LCD and graphic test : PASS

just a hard drive error: ERROR CODE 0146

MSG ERROR CODE: 2000-0146

test: FAIL

What do you think about?  can it be just a photoshop problem ?

Hello Kezo,

Since the test on the LCD passed, I would suggest you to check if you are facing the issue only with Photoshop or with some other applications as well. 

Regarding the 0146 error code on the hard drive I would like to say: 
Error code: 2000-0146 (DST Log contains previous errors) refers to previous errors in the hard drive which might not really be a hardware failure. Please try the following steps:

-- Reset the BIOS to the defaults for these error codes. For more information on resetting the BIOS to the defaults, refer to the Resetting the System Setup (BIOS) to its Default Settings section. 

-- After resetting the BIOS to the defaults, re-run the diagnostics if you receive the same error code the hard drive needs to be replaced. 
 **Note: If the computer is able to boot into Windows you should back up your important information and files, for information on how to do this, refer to Dell Knowledge Base article Backing up and Restoring Important Files and Data. 

Please write back with results, would be glad to assist you further.

Hello Kezo,

Since you got the error message even after resetting the BIOS to defaults, the hard drive needs a replacement. Does the computer have an active warranty? You can check the warranty status here. In case of expired warranty scenario, we would not be able to extend warranty entitled services. If the warranty on the computer has expired, you may contact our Expired Warranty Services (this is for US based customers).

Regarding the other problem, I would like to know, how many beeps do you hear? I would also like to know if you have checked connecting an external monitor to the laptop. 

Please write back for further questions, would be glad to assist you further.
