When converting DVI interface to HDMI, the supported resolution mainly depends on the type of DVI interface (single channel or dual channel) and the specifications of HDMI interface and adapter cable. DVI interface type and resolution
Single channel DVI: The maximum resolution can reach 1920x1200 and supports a refresh rate of 60Hz. This configuration is suitable for most high-definition displays.
Dual channel DVI (DVI-D): The maximum resolution can reach 2560x1600, and it also supports a refresh rate of 60Hz, or up to 120Hz at a resolution of 1920x1200. The dual channel DVI interface provides higher data transfer rates, thereby supporting higher resolutions and refresh rates. HDMI interface and resolution
The HDMI interface supports a wide range of resolutions, ranging from lower 320x240 to higher 5760x3240. However, the actual supported resolution also depends on the version of the HDMI interface and the performance of the monitor. For example, HDMI 1, 4a or higher versions support 4K resolution (up to) 4096x2160@24 Hz or 3840x2160@30Hz ）. Resolution support for DVI to HDMI conversion
When using a DVI to HDMI adapter cable, the main application is the functionality of the DVI interface. If the DVI interface is single channel, the maximum supported resolution after conversion is 1920x1200; If the DVI interface is dual channel (DVI-D), the maximum supported resolution after conversion is 2560x1600.
Even if the DVI-D interface supports high resolution, after converting to HDMI, if the HDMI interface or cable specifications do not support the corresponding resolution, it may not be possible to achieve high-resolution output. Due to the HDMI interface supporting audio transmission, while the DVI interface does not support audio, audio signals may not be transmitted after conversion.
The maximum resolution supported when converting DVI interface to HDMI can reach 2560x1600 (when both DVI-D interface and HDMI interface and cable specifications are supported). However, the actual achievable resolution also depends on the performance of the monitor and the capabilities of the graphics card, as well as the specifications of the HDMI interface and cables.
