YITROX AV Svideo to HDMI Converter Upscaler, 3RCA CVBS AV Svideo to HDMI Converter Scaler, Support 1080P for Wii, PS2, PS3, Xbox 360, Blu ray Player, DVD and More

【3 Video signals input to HDMI】Supports 3 types of signal inputs, AV/S-Video/HDMI (direct pass). Convert three types of signals into HDMI signals, with a maximum resolution support of 1080P. Note: The output resolution of HDMI depends on the size of the input resolution and cannot be enlarged, only signal conversion is allowed. Three different video signals can be selected for input through the device switch button. Reasonably use old analog signal equipment to match new televisions, monitors, and projectors. (Note: Reverse usage is not supported).
【Scaler technology】The video is amplified and reduced by the Scaler chip, and then converted into HDMI signal for display. Scaler actually changes the horizontal and vertical resolution of an image. Ensure that the output video is compatible with the resolution of the monitor and displays properly. Note: The final displayed image quality is related to the image quality of the input signal. For example, when the input image is 480P and the Scaler technology is used to adapt to a 1080P monitor, the actual image quality is still 480P. Because it can only adapt to resolution and cannot significantly improve image quality. Only a small portion of optimization can be achieved.
【Multiple video resolutions】Supports 4 input resolutions: 480i/p (60Hz), 576i/p (50Hz), 720p (50/60Hz), 1080i/p (50/60Hz). Supports 5 HDMI output resolutions: (800x600, 1024x768, 1280x720, 1280x1024, 1920x1080). Vibrant colors, no delay, no jitter.
【Image Quality Compensation】Partially optimized the image quality for Wii, Xbox, and PS game consoles. Using 3D compensation technology, the image will not shake and will be more delicate. Perform motion optimization, color optimization, and digital noise reduction through chip algorithms. Effectively eliminate jitter and trailing in moving images, optimize image contrast, and make the image clearer and more delicate. Note: Only partial picture quality compensation and contrast optimization can be achieved, but it is not a picture quality upgrade. Cannot achieve the effect of converting 480P to 720P.
【Audio and Video Synchronization】The converted HDMI signal achieves delay free audio and video synchronization and provides an AUX audio port. Suitable for Wii Xbox One、PS2、PS3、 Old set-top boxes, old Blu ray DVD players, etc. No need to install drivers, plug and play.
