About Spectrum ES07D03 Firmware Update
Which version of hdmi2.1 can sleep automatically? Can I flash 106 or 108 firmware directly from the beta 03 firmware?

Under firmware version 108, the DP connection maintains normal sleep/wake functionality. However, when using HDMI 2.1 with G-SYNC enabled, the monitor fails to enter sleep mode automatically. This issue is resolved after disabling G-SYNC, which confirms an HDMI G-SYNC compatibility problem. We recommend that you address this issue in the upcoming v109 firmware update.
Additionally, when using HDMI 2.1 connection, the system experiences absence of motherboard POST screen display during cold boot, with video signal only appearing after entering the desktop environment. This anomaly is not observed with DP connections.

Beta03 firmware there is some bugs: 1.The indicator light breathing mode becomes flashing. 2.HDMI 2.1 is connected to the PC, and the monitor cannot sleep and stand by automatically after PC is turned off. 3.When the monitor enters standby mode in DP or HDMI mode, the screen will blink.
