Monitor entering Power Save Mode

[vanityz]

Hello , i have this monitor for 2 months already working fine Dell UltraSharp U2515H 25" LED
The problem is the following... Last night i switched off computer/monitor then i went to bed and i realized that computer was still on , so i tried to switch on monitor to see what happened and a message poped up '' Entering Power Save Mode '' , from this moment till now i can't get rid off this message.

So i tried to replace RAM to a different , Plug off and in the GPU with no results, the same message.

Then i pluged in my old monitor and it is working fine , however i tried to plug Dell monitor back and i switched from DisplayPort connection to MiniDisplayPort connection in monitor panel ( both are connected at the same time since 2 months ) and it works on mDP but not in DP.

Any idea what can be causing this problem ?
Any real difference for gaming ( recording and renderizing also ) between mDP and DP ?

there are no differences for gaming between mDP and DP.
the monitor is displaying that message because you havent turned on your computer and thus there is no signal to the monitor.

I have turned on the computer and im currently using mDP option from monitor panel because if i choose DP option it just pops this message '' entering power save mode '' and then black screen.

I'm starting to think that when i switched off computer last night , there was a Intel graphic integrated card update pending from windows( can i just uninstall it ? http://pix.my/jQTxlvoL ) , may be this causing some kind of interferences ? the thing is that the computer never switched off , i had to force shut down it this morning.

Have you tried pressing the source button on your monitor?

yes , that's how i change from DP to mDP and then it worked , but i want to use DP... as the past 2 months was working perfectly , dont know what happened, didn't touch anything.

yes maybe the update was still running when you switched it off. the best you cand do is to enter windows while using the mDP port and unistall the intel graphics driver and then download the latest drivers from intel.com. then you will be able to use the DP port. it seems that due to the incomplete driver your DP isnt being recognized by the motherboard.

I want to clarify that im using a gtx 1080 gpu , not integrated mobo gpu , still can i let it be completely uninstalled ?

did you try reinstalling the gtx 1080's drivers? uninstall the intel graphics driver first. also try connecting that monitor to some other PC that has DP and see if if it works. if it doesnt then probably your monitor is defective. if it does work then i suggest you do a clean install of windows+flash your bios with the latest one from the manufacturer's site.there is a chance of your GPU being defective too...so give a call to customer support if you get the time.

So i uninstalled Intel Graphics and nvida drivers through DDU program then installed back the latest nvidia drivers 372.70 with no changes , still don't work on DP and about testing monitor... i have no way to test this since i dont own an other GPU DP ready.

Well since i did RMA this monitor already one time , because the first one came defective ( it will shut down every 20 sec ) im not confident in this brand / model anymore, so i will change it for an Acer Predator XB271HU 27" LED and if it doesn't works properly neither i will RMA the GPU.
Thanks for all the help @GamerBoy357 , i will pick you as the best solution for all the effort 😛
