It will be understood that, although the terms "first", "second", "third", etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms, but should be used to distinguish one element, component, region, layer and/or section from another element, component, region, layer and/or section. Thus, a first element, component, region, layer, and/or section discussed below could be termed a second element, component, region, layer, and/or section without departing from the teachings of some embodiments of the present disclosure.
It is noted that the following disclosure provides many different embodiments, or examples, for implementing different features of the invention. The following specific examples and arrangements of components are merely illustrative of the spirit of the invention and are not intended to limit the scope of the invention. Moreover, the following description may repeat reference numerals and/or letters in the various examples. However, this repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed below. Moreover, the description below of one feature connected to, coupled to, and/or formed on another feature, and the like, may actually encompass a variety of different embodiments that include the feature in direct contact, or that include other additional features formed between the features, and the like, such that the features are not in direct contact.
Fig. 1 is a block diagram of an electronic device according to an embodiment of the invention. As shown in fig. 1, the electronic device 100 includes a display card 110 and a processor 120, wherein the electronic device 100 is coupled to a display 10. The display card 110 reads the extended display identification data EDID of the display 10, wherein the extended identification data EDID of the display 10 is stored in the register 11. According to an embodiment of the present invention, the register 11 is an Electrically-Erasable Programmable Read-Only Memory (EEPROM). According to an embodiment of the present invention, when the display 10 is shipped, the EDID is extended by writing the predetermined resolution, the refresh rate and the maximum transmission bandwidth of the display 10 into the register 11, wherein the predetermined resolution is the highest resolution of the display 10.
After the display card 110 reads the extended display identification data EDID of the display 10, the processor 120 determines that the display 10 can display the predetermined resolution at the highest first update rate according to the extended display identification data EDID of the display 10, and determines whether the display 10 can display the predetermined resolution at the second update rate higher than the first update rate according to the extended display identification data EDID. According to an embodiment of the invention, the first update rate is a maximum predetermined update rate for displaying a predetermined resolution in the EDID of the display 10.
When the processor 120 determines that the display 10 can display the predetermined resolution at the second update rate, the processor 110 adds the second update rate to the EDID and writes the updated EDID into the register 11 of the display 10. When the user selects the second update rate displayed by the display 10, the display card 110 sends a corresponding display signal SD to the display 10, so that the display 10 displays the predetermined resolution at the second update rate.
Therefore, the user can use a higher update rate to display the preset resolution, and further obtain better visual experience. According to an embodiment of the present invention, the electronic device 100 is a computer. According to another embodiment of the present invention, the electronic device 100 is a game machine, such as PlayStation, Xbox, Switch, and any future game machine requiring a high update rate. When the computer or game machine is coupled to the television or monitor, it can be determined whether the predetermined resolution can be displayed at a higher update rate according to the information of the EDID of the extended display identification data of the monitor 10, so that the user can obtain a better visual experience. The detailed process of the electronic device 100 for increasing the refresh rate of the display 10 will be described in detail below.
Fig. 2 is a flowchart illustrating a display method according to an embodiment of the invention. The following description of the flow chart of fig. 2 will be combined with the block diagram of fig. 1 to facilitate the detailed description.
As shown in fig. 2, the extended display identification data EDID stored in the register 11 of the display 10 is first read by the display card 110 (step S201). Based on the read EDID, the processor 120 determines that the display 10 can display the predetermined resolution at the first update rate (step S202). According to an embodiment of the present invention, the predetermined resolution is a highest resolution of the display 10, and the first update rate is a predetermined highest update rate for the display 10 to display the highest resolution.
Next, the processor 120 determines whether the display 10 can display the predetermined resolution at a higher update rate according to the extended display identification data EDID (step S203). More specifically, in step S203, the processor 120 determines whether the display 10 can display the preset resolution at an update rate higher than the first update rate. According to an embodiment of the present invention, the extended display identification data EDID includes a predetermined resolution, a first update rate and a transmission bandwidth, wherein the transmission bandwidth is a maximum bandwidth of a control panel of a Timing Controller (Timing Controller).
When the processor 120 determines in step S203 whether the predetermined resolution can be displayed at a higher update rate, the maximum update rate (hereinafter referred to as a second update rate) allowable for the display 10 is first calculated by using formula 1, where R is the maximum update rate, BW is the transmission bandwidth, H is the horizontal pixel, and V is the vertical pixel, and the transmission bandwidth, the horizontal pixel, and the vertical pixel are extracted from the extended display identification data EDID.
Next, the processor 120 determines whether the second update rate is greater than the first update rate. When the second update rate is greater than the first update rate, the processor 120 determines that the display 10 can display the predetermined resolution at a higher update rate. When it is determined in step S203 that the display 10 can display the predetermined resolution at a higher update rate according to the above-mentioned process, the processor 120 adds an update rate (i.e., a second update rate) higher than the first update rate to the extended display identification data EDID (step S204).
According to an embodiment of the invention, the processor 120 further writes the extended display identification data EDID updated in step S204 into the register 11. According to an embodiment of the invention, when the step S203 determines that the display 10 cannot display the predetermined resolution at the higher update rate, the display method 200 is ended.
Next, the processor 120 further determines the grade of the display card 110 (step S205). When the processor 120 determines that the display card 110 is at the entry level, the second update rate is hidden (step S206), so that the user cannot select to display the predetermined resolution at the second update rate.
When it is determined in step S205 that the display card 110 is in the middle-level, a second update rate is displayed on the display 110 for the user to select, and an adaptive synchronization (adaptive sync) function is started (step S207). When the display card 110 is determined to be in the high-level, the second update rate is displayed on the display 110 for the user to select, and the adaptive synchronization function is turned off (step S208).
According to an embodiment of the present invention, the processor 120 determines the type of the display card 110 to belong to one of the entry level, the middle level and the high level by using a lookup table. For example, current display cards are manufactured by Intel, Hadamard (NVIDIA) and advanced micro-semiconductor (AMD), respectively. When the processor 120 knows that the display card 110 belongs to the Intel chip according to the model of the display card 110, the processor 120 determines that the display card 110 belongs to the entry level, and therefore hides the second update rate. According to an embodiment of the present invention, in order to prevent the entry-level display card from providing data transmission with a high refresh rate, the second refresh rate is hidden to prevent the visual experience of the user from being degraded.
According to another embodiment of the present invention, when the display card 110 is determined to belong to GTX 960, the processor 120 determines that the display card 110 belongs to the middle rank, thereby displaying the second update rate and activating the adaptive synchronization function. According to an embodiment of the present invention, when the display card 110 is determined to belong to the middle-level class, the adaptive synchronization function is automatically turned on to avoid tearing of the image, thereby improving the visual experience of the user.
According to another embodiment of the present invention, when the display card 110 is determined to be GTX 1080 of Hakka, the processor 120 determines that the display card belongs to a high level, thereby displaying the second update rate and turning off the adaptive synchronization function. According to an embodiment of the present invention, since the display card belongs to a high-level class, the degree of enhancement of the picture may be limited regardless of whether the adaptive synchronization function is turned on, and thus the adaptive synchronization function is reserved for the user to control. The foregoing description is for the purpose of illustration and explanation, and is not intended to be limiting in any way.
