I hope that when HDR is turned on, a slider can be added as a function to adjust the SDR brightness. This is because currently, only LG monitors can still adjust the brightness when HDR is enabled, while other monitors cannot. Thank you!
希望能加入hdr开启时，可增加一条滑动条用于调整sdr亮度的功能，因为现在只有lg显示器在开启hdr时仍然能调整亮度，而其他显示器不行。谢谢！
