VESA显示电源管理信号 （英语：VESA Display Power Management Signaling，简称DPMS）是VESA制定的通过显示卡对显示器电源管理的标准。
DPMS规定如果一定时间不对计算机进行操作时显示器自动进入节电模式。原本根据美国的标准制定。
原理是根据垂直同步信号(V-sync)和水平同步信号(H-sync)的有无来判断。
以下为节电模式的规定。
| Normal | Standby | Suspended | Off | |
|---|---|---|---|---|
| H-sync | on | off | on | off |
| V-sync | on | on | off | off |
| Power use | 100% | <80% | <30W | <8W |
