DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 1-2, 9-11 and 18-19 are rejected under 35 U.S.C. 103 as being unpatentable over Kwon (US 2020/0336716) in view of Qiu (US 2015/0186303), and further in view of Chuang et al. (US 10,785,386, cited in IDS dated 08/20/2025). Regarding claim 1, Kwon discloses a display apparatus (Fig. 2; [0045], e.g., display apparatus 100) comprising: a display (e.g., display panel 110); a second standard port configured to be connected to a second standard port of an external device ([0126], e.g., a HDMI standard port is connected to a HDMI standard port of an external device 100); communication circuitry (Fig. 3; [0061], e.g., receiver 120) configured to receive a second standard image and variable refresh rate information through the second standard port ([0128]-[0129], e.g., receive a HDMI standard image with variable refresh rate information (VRR) through the HDMI standard port); a controller comprising at least one processor (Fig. 3; [0106], e.g., controller 170 comprises a processor 170), wherein the controller is configured to: change an image processing mode based on the variable refresh rate information ([0130]), and control the display to display a second standard image (Figs 13A-13C; [0161], e.g., display an HDMI image). Kwon further discloses wherein the external device comprises a first standard port ([0126], [0132], e.g., a display Port standard (DP)). Kwon does not specifically disclose wherein the second standard port configured to be connected to the first standard port of the external device, wherein the communication circuitry is configured to receive a first standard image, and wherein the controller is configured to convert the first standard image to a second standard image based on the variable refresh rate information. However, Qiu discloses a display apparatus (Fig. 1; [0013], e.g., the display unit 160) comprising: a second standard port ([0013], e.g., the display unit 160 complies with a Dual mode Display Port (DP++) standard) configured to be connected to a first standard port of an external device ([0013], e.g., the signal source unit 120 complies with the DP standard); and communication circuitry (Fig. 1; [0024],[0032], e.g., a receiving circuit) configured to receive a first standard image and variable refresh rate information through the second standard port ([0013], [0032], e.g., receive a Display Port standard (DP) image signal through the Dual mode Display Port (DP++) standard). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to use the teachings of Qiu in the invention of Kwon for receiving a Display Port (DP) standard image through a HDMI standard port because Qiu teaches a display device provides a simpler user interface that allows the users to operate a display device easily without purchasing an extra adapter (see [0035] of Qiu). Kwon in view of Qiu does not specifically disclose wherein the controller is configured to convert the first standard image to a second standard image based on the variable refresh rate information.

However, Lin discloses a display device (Fig. 1; col. 4, lines 43-53, e.g., a display device 200) wherein a controller configured to match a back porch of an output standard image with a back porch of an input standard image (Figs 2 and 8; col. 1, lines 52-60, col. 10, lines 1-5, col. 13, lines 45-62; e.g., match a back porch (K clock cycles) of an output standard image with a back porch (K clock cycles) of an input standard image by synchronizing the horizontal synchronization signal (HSYNC2) of a standard output image (VGA or Super VGA) with the horizontal synchronization signal (HSYNC1) of a standard input image (VGA or Super VGA)). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to use the teachings of Lin in the invention of Kwon in view of Qiu and Chuang for matching a back porch of a second standard image with a back porch of a first standard image in order to provide an image in a format suitable for display by a display device (col. 5, lines 10-12 of Lin). Regarding claim 20, Kwon in view of Qiu and Chuang does not specifically disclose the non-transitory computer readable storage medium of claim 18, wherein the non-transitory computer readable storage medium further store instructions to match an output clock count of the second standard image with an output clock count of the first standard image to convert the first standard image to the second standard image. However, Lin discloses a display device (Fig. 1; col. 4, lines 43-53, e.g., a display device 200) wherein a controller configured to match an output clock count of a standard out image with an input clock count of a standard input image (Figs 2 and 8; col. 1, lines 52-60, col. 4, lines 50-60, col. 5, lines 40-67, col. 6, lines 1-9, col. 13, lines 45-50; e.g., synchronize an output clock count PCLK2 of a standard output image (VGA or Super VGA) with an input clock count PCLK1 of a standard input image (VGA or Super VGA)). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to use the teachings of Lin in the invention of Kwon in view of Qiu and Chuang for synchronizing a pixel clock count of a second standard image with a pixel clock count of a first standard image in order to display an improved image by a display panel (col. 6, lines 1-9 of Lin). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Lee (US 2011/0193884) discloses a display system (Fig. 3) comprising a first standard port ([0012]) configured to transmit a first standard image from a source to a second standard portion of a display device ([0012], [0014]). Sharma et al. (US 2013/0227631) discloses a display system (Fig. 1) comprising a video processing system configured to convert a first standard image to a second standard image (Fig. 3; [0025]-[0027]). Liu et al. (US 2010/0091180) discloses a display system comprising a host device, a signal conversion apparatus and a display device (Fig. 1; [0017), wherein the signal conversion apparatus is configured to convert a first standard image to a second standard image ([0017]-[0018]). Lee et al. (US 7,548,233) discloses a display device comprising an image scaling circuit configured to convert a first image to a second image by matching an input vertical synchronization signal of the first image with an output vertical synchronization signal of the second image (Figs 6-7; col. 4, lines 30-43, e.g., the input Vsync signal 610 and the output Vsync signal 630 are synchronized to prevent the appearance of short lines and long lines).
