welcome to Energy Star devices, learn that newer devices, now have a newer deeper sleep. (usa fed laws...yah) global worming(sic) and all that.?
even monitors down to 2watts super deep sleep. and PC's and even GPU cards.
if you dont like the delay change the power settings in your PC, window control panel. power settings.
in all cases we first make sure all drivers for all things in the PC are current, if not sleep modes love to fail.
then change the setting what you want.
there are s0 to s5 power modes, in the hardware.. ok.?
set it as you like.
or hybrid mode.
Microsoft documents all this sleep stuff. if you go there and read how.
it's not a bub, it's a FEATURE !
the longest recovery is if the RAM is cleared and then the PC must recover from hdd, swap files,!!
not counting true cold boot you dont know how to use yet, or turn on. (fast boot off) ( the most slow of all and far worse on any HDD)
try reading this first
if using say SSD main drive, SSD0 and you used deep hiberate mode, it will recover 10 or MORE
times faster than any HDD on earth(hdd is slug) so making alien PC comparisons is not fair is it.>?
learn to use power modes now even google that, get 1million hits.
I call this cockpit error , .... if a PC is super old and has HDD the HDD can be bad. (and will be even more slow)
if all this is painful why not turn it all off. (even use presentation mode like I use)
some call this the freeze ,etc. see the 13 cherry picked custom power settings at the end of linked page.
set it as YOU like,ok>? it is a FEATURE. not a bug
that is al there is on sleep, on old PCs we can go all day long fixing that, lack of drivers for w10 and worse bad HDD. but ill skip that.
< I am using the DisplayPort cable that came with the monitor.
Hmm. Well, it's probably time to try it on a different computer, and
try a more-normal conventional DP or DVI computer monitor on the XPS .
... see where the problem follows.
My best (real / computer-class) monitor is my:
Dell 27" u2717D UltraSharp Infinity-Edge IPS 16:9 QHD (1440p) Monitor
It's been on for years now. It goes to-sleep often. It wakes in about 2 seconds. Same with my Dell u2410 .
Is it going to sleep or into hibernation?
You can try changing some of the Power settings in the active Win 10 power plan. Open the Win 10 Power options screen and ID the active power plan. Click the link to change its settings and on next screen, click the link for Additional Options.
On that screen, disable hibernation, disable hybrid sleep and disable PCI Express Link State Management. Save the changes to the power plan and reboot.
See if that helps...
