Custom Resolution Utility (CRU)

Hi! When using a Philips Oled 2024 TV (55OLED809/12) connected via hdmi 2.1 to a PC, there is such a problem that when the TV is turned off, every hour (constant) this display reconnects to Windows (with the appropriate sound of the device connection, but the most problematic thing at this moment is the system freeze for 3 seconds) when the TV is turned on ( doesn't matter what happens on it) there is no such problem, but it is worth turning it off, it is redefined hourly in Windows. I've already tried everything possible, installed a clean Windows, reset to default settings TV,updated the TV firmware, turned off all possible energy-saving settings in both TV and Windows, turned off the HDMI-CEC on the TV, deleted the drivers via DDU, turned off HDCP, rearranged the hdmi cable to different TV ports. Nothing gave any results, anyway, if the TV is turned off, it reconnects every hour, and several device setup manager event 131 errors occur at the same time when viewing Windows events. When searching for a similar problem, I found no solutions except how to disconnect the hdmi cable from the TV or de-energize the TV itself (this naturally gives the result, since the TV disappears from the devices in Windows completely and no longer reconnects), but this solution is not very convenient. Of the options that could solve this, it is most likely to connect the TV via a DP adapter to HDMI, but with this connection, the VRR will most likely stop working. So, maybe someone knows at least some solution to this problem, or maybe something needs to be turned on/off in the HDMI 2.1 settings in the CRU? Before that, I used a cheaper cable that worked poorly at 48 Gbps (the picture disappeared at a random moment, I solved the 40 Gbps limit in the CRU) I thought there was a reconnection problem with the TV turned off in this cable, but no, by buying a more expensive cable that works fine with standard settings, everything is the same. I used Windows 11 23H2, and also tried to upgrade to 24H2. RTX 4080 graphics card
