Tower ECT1250, requires 2 keyboard keypresses to full return from sleep mode

Question

A single keypress does in fact wake up the computer. You hear it start up, and the power button light turns solid. It is awake. However, the monitor (Dell S2725H) is still asleep (power light pulsing). Now if I press another key or a mouse button, the monitor wakes up.

Previously I had this exact same setup (same monitor) but with a Dell XPS 8900 and everything was fine (single keypress or mouse button woke up computer AND monitor). All I did was replace the XPS with the ECT1250 and now requires 2 keypresses to wake up computer and monitor. I have never used a computer that required 2 keypresses so it is a bit frustrating and I keep forgetting to press twice and think there is a problem until I remember.

Thanks,
-Bill

To which port on the XPS 8900 was the S2725H connected? To which port on the Tower ECT1250 is the S2725H connected?

@DELL-ChrisM2​ They were both connected to HDMI ports. On the XPS 8900 it was connected an the HDMI port on an Nvidia GFX card. On the ECT1250 it is connected to the motherboard HDMI.

@wbdoll​ Just confirming, the Tower ECT1250 does not have an added video card?

Did you test both S2725H HDMI in ports?

wbdoll · Answer

@DELL-ChrisM2​ I did not, but I can. However, I should have mentioned I tried a different HDMI cable and even a different monitor (different brand as well  but same resolution). So it seems like it is the ECT1250 (maybe GFX but I did ALL updates, Windows and from Dell support including BIOS). Thanks.
