  1. Well: I finally realized that by degrading the frequency of the graphics card (from 60Hz to 40Hz) the image improves substantially. The problem is that it is not enough to play, since the graphics are of low resolution. I made a summary of the vBios to make sure to leave the factory values to perform the tests. I will try another different graphics card (Quadro FX8000) to make sure it is not a problem with the graphics card and start thinking that the problem could be on the LCD or on the motherboard. As always, any suggestion will be very welcome. Greetings.
  2. Hello: This is my first post, and I apologize for my poor English. I have a problem with the image that is displayed on my computer's LCD and I do not know how to solve the issue. I have an Alienware M18x R3 (2014) with this configuration: CPU: 4930MX RAM: Crucial 16Gb GPU: Nvidia GTX780M (x2) SLI BIOS: A12 unlocked. O.S: Windows 7 Professional and Windows 8.1 Pro The equipment was bought from a user who had the problem of the 8 beeps due to LCD death when updating to Windows 10, and that is why I was able to buy it very cheaply. I have changed the LCD according to model specifications on the official DELL website (18.4 "FHD LTM184HL01 C01 IPS 40pins For DELL Alienware M18X R1 R2 0XJY7J XJY7J). After the replacement of the LCD the computer starts Windows 8.1 pro and Windows 7 without problems, the image is shown on the LCD normally with the configuration of integrated graphics (IGFX) in BIOS, but when I set BIOS to boot in dedicated graphics mode (PEG) , the image on the LCD is defective, it seems that the resolution is exaggeratedly low with false colors, colored stripes and pixels that changes colors. I think, It is not an O.S problem, since these artifacts appear from the BIOS boot on the computer. Connecting an external monitor the video signal is perfect, and I can play in SLI configuration without problems, and I have performed a satisfactory stress test to the 780M graphics. I can only think that the LCD that I bought is not 100% compatible and that the 780M graphics card finds in it something that it does not like (frequencies?). Do you know about any tool that can help to diagnose the problem? I add some links to photographs: http://www.imagebam.com/image/ae4ca81219395014 http://www.imagebam.com/image/158a971219394964 http://www.imagebam.com/image/66ea561219394994 Any suggestions would be welcome. I appreciate your comments very much. Greetings.
