white rectangle on the Screen

This question is not answered

I need to know. There is a white rectangle on the screen of my laptop and it cant be deleted or drag away. If I double click or right click nothing happens. What could this be. Please help.

  • Does the cursor disappear when you mouse over that white rectangle, or can you still see it?  What happens if you open an application?  Does the problem show up on an external monitor (assuming a notebook) or a different monitor (for a desktop)?

  • Chisale, welcome to the community forums


    Always best to give as much information as possible, otherwise replies tend to request more info

    Hence the “narrowing-down” type questions from Larry to reduce the guessing game

    I.e. does white rectangle appear all the time or just when moving the mouse over a certain area of screen, same or what part of screen, on desktop screen only or just when web browsing etc…


    In the absence of more information – so it’s a long shot guess:


    There is a graphical user interface (GUI) feature called ToolTips (bit like a pop-up) normally initiated by mouse “hover” movement & there are a number of different alternative GUI software suppliers


    Some ToolTips software causes a rectangle box to appear empty & remain behind or partially displayed

    Some GUI software suppliers provide a ToolTips disable type option


    If you haven’t installed such 3rd party GUI software it could be MS Windows ToolTips?


    If it is then try the following

    Right click on any empty area on desktop screen > select Properties > Appearance tab > Effects button

    Uncheck the enable box “Use the following fade effect for……tooltips”

    Click OK twice


    If the above doesn’t fix your problem, please provide more information



  • Chisale,

    I hope that white rectangle is clearly defined.  The last time I saw a white rectangle on an Inspiron 1525 display, it was bad news.  The rectangle was a broken display caused when a small Bible was placed against the top of the laptop while being transported in a soft nylon carrying case. 


  • My pc was fine last night and I have been using it frequently. Today I opened it and there is a tall solid white rectangle in the top left corner with black smudge at the bottom of it. My curser is hidden behind it. It does display normal on the television when I hook up with hdmi cable. I am guessing that the screen is irrepairable since it looks fine on the tv and not on notebook.

  • Hi rossr1016,

    It appears to be an issue with the LCD. If using a Dell laptop, you may follow the steps below to run self test on LCD :

    • Power off your computer
    • Press and hold 'D' button on laptop keyboard and press Power button to run the tests.

    If the black patch is visible during the self test as well, then it points towards a hardware failure and the LCD might need a replacement. Please check the LCD screen for any accidental damages. Please post a picture if possible.

    Please reply with the findings. Will take it further from there.

    Thanks & Regards,
    Sundeep B

  • I have a similar problem . Small white rectangle top left of desktop.  194x55 pixels width x height. Sits 205 pixels down and 149 pixels from the left. RGB colours are 240,240,240

    Stays  on top. Cant click or double click it. Cant put another icon in it's place if you try the mouse changes to no entry sign. Mouse icon goes over the top of it. Icons placed there before it arrives are hidden beneath it.

    I have this on an Alienware M17x r4 with 3d screen. I think it appears after I leave the machine and the screen / machine goes to standby but not certain about this.

    What is it?Confused


  • Forgot to put the picture of the screen in... here it is...

    You may also check in Safemode with networking. Restart the computer and tap F8 at Dell logo and select Safemode with networking.
