The system includes a housing, a screen capture device, a serializer, and a display interface. Further, the system includes a sound capture device, and a bracket to secure the display device to the system. The method includes receiving an image of a display device, converting the image to a digital signal, serializing the digital signal, and transmitting the serialized digital signal to an outside device. ## Claims ### Claim 1 A system for capturing output of a display device, the system comprising: a housing; a screen capture device mounted to the housing, wherein the screen capture device configured to capture images shown on the display device and convert the images into a digital signal, the screen capture device includes: a first polarizer configured to allow polarized light associated with a first polarization of the first polarizer while blocking light waves of other polarizations, a color filter configured to separate the polarized light, liquid crystals positioned between the color filter and a second polarizer, the second polarizer configured to allow for polarized light associated with a second polarization of the second polarizer; a serializer electrically connected to the screen capture device and mounted to the housing, wherein the serializer configured to serialize the digital signal into a serialized digital signal to allow for transmission; and a display interface electrically connected to the serializer and mounted to the housing, wherein the display interface is configured to transmit the serialized digital signal to an outside device. ### Claim 2 (depends on 1) The system of claim 1, wherein: the screen capture device further configured to calibrate the images received from the display device to account for color vision deficiency. ### Claim 3 (depends on 1) The system of claim 1, wherein: the screen capture device further configured to detect defective pixels on the display device and to correct the images received. ### Claim 4 (depends on 1) The system of claim 1, wherein: the screen capture device further configured to detect defects on a screen of the display device and to correct the images received. ### Claim 5 (depends on 1) The system of claim 1, wherein: the serializer further configured to continuously serialize the digital signal, wherein the display interface continuously transmits the serialized digital signal. ### Claim 6 (depends on 1) The system of claim 1, further comprising: a sound capture device mounted to the housing, the screen capture device electrically connected to the screen capture device and the serializer, the sound capture device configured to convert visual sound waves shown on the display device into a digital audio signal, the sound capture device further configured to transmit the digital audio signal to the serializer for serialization. ### Claim 7 (depends on 1) The system of claim 1, wherein the display interface is an HDMI interface. ### Claim 8 (depends on 1) The system of claim 1, wherein the display interface is a display port interface. ### Claim 9 (depends on 1) The system of claim 1, further comprising: a bracket mounted adjacent to the screen capture device, wherein the bracket holds the display device in place. ### Claim 10 (depends on 9) The system of claim 9 wherein the bracket is mounted to allow for the display device to face away from the outside device, whereby allowing a camera of the display device to capture a displayed output shown on the outside device. ### Claim 11 A method for capturing output of a display device, the method comprising: receiving an image of the display device by detecting light being emitted from the display device onto a screen capture device, wherein the image is displayed on the display device and the screen capture device includes: a first polarizer configured to allow polarized light associated with a first polarization of the first polarizer while blocking light waves of other polarizations, a color filter configured to separate the polarized light, liquid crystals positioned between the color filter and a second polarizer, the second polarizer configured to allow for polarized light associated with a second polarization of the second polarizer; converting the image into a digital signal, wherein the digital signal is digital information of the image; serializing the digital signal into a serialized digital signal, wherein the serialized digital signal is configured to be transmitted to an outside device;
