Windows 10: Black & White screen from sleep mode

Don't know if this is the correct place or not but here goes......I have 2 almost identical HP P6 desktop pc's 2400t/2420t bought new in 2013 both running Win10 Home and one of them is giving me a black & white screen instead of the regular color when I bring it out of sleep mode.......Everything is normal on the screen its just in black & white.

And all I do to fix it is restart it and it comes back to color as normal everytime......This started happening about 3 months ago and it does it about once in every 8 or 10 times I bring it out of sleep mode.

And just to let everybody know this pc is hooked up to my 55" Vizio 4K smart tv which is 1 year old.

The other pc has never done it ever and the one that does it has a Nvidia/GF GT 620 1GB card with 12 gb of memory......Let me know anybodys thought on this!

Windows 10 Creation update sleep mode problem

I installed the Creation update for my laptop last month. Since then, whenever the system goes to sleep mode and turn I it on again, the screen is black or, more frequently, a mostly black-and-white pixel mush. I can see the cursor location as it is shown
on the screen as a big square, but nothing else.

The only way so far, to make the screen work again, is to do a hard restart.

I have now disabled the sleep mode but i would like a better solution for this.

Windows 10 PC Won't turn on after Sleep Mode

These past two dies, oddly after I updated my Dell PC to Windows 10, would not turn on after going to Sleep Mode. This final time that I attempted to turn on from Sleep Mode, I (blindly b/c the screen was black) logged in to my computer using my Pin as I
usually do an the screen went white with black lines and when I moved my mouse, a grey bow followed where it was supposed to be. This weird screen went on and off until I force shut the computer down. I can still force shut down, restart, and or turn the computer
on, but it's the sleep mode that is utterly "broken".

How can this get fixed?
