Hi guys it´s me again can you tell me if this holds the trueth?

I got this reply from other forum text bellow,

Well if you leave the monitor off during the boot up into windows or linux, the O/S will assume there is no display attached because it probe for EDID and didn't get a response. Newer monitors have EDID on the standby voltage to fix this issue.

My display monitor is a Cob Hd 15" TV with VGA and HDMI
i guess there is no EDID for this cheap display,
 
Since it is a TV it might be defaulting to another setting if it does not find a PC signal. Boot the pc with the monitor off and then turn the monitor on and go through all of the input settings. See if one of them gets a signal from your PC.

Thanks salvage: the TV is set to VGA input and my problem is if i start the PC before the monitor display, the PC is on but the display is showing on a black screen resolution 860x700 since the con fig on the Intel hd card is set to 1920x1080 resolution it makes since that the monitor stays black due to incompatible resolution,

also i found this info about the matter( EDID) although this is too technical for me maybe somebody here make some sense of of it and explain it in lame terms.

can you boot into low graphics mode? If you can open monitors and reset the configuration to a usable display setting.
