THIS IS SORT OF STUPID.
I updated the BIOS to the version 3802 of 2015.
The problem with the video post screen and initial BIOS screen was resolved this way: Under "Option ROM Messages," in the "Boot" menu of the BIOS, changing to "Force BIOS" corrected the initial screen resolution. I don't know how I missed this. I'm familiar enough with the P8Z68-V Pro BIOS menus -- I have three systems with these boards.
There was just one other thing I noticed about the "Ai Tweaker" menu that gave me some uneasiness.
Whenever the BIOS was reset, "iGPU Max. Frequency" would be set to "1250" instead of "Auto," and the "iGPU Offset Voltage" would show "1.5V" -- in red. I had never spent much time overclocking or tweaking the onboard Intel Graphics, but I'd never seen this behavior before, even so.
Resetting the BIOS would change "Ai Overclock Tuner" to "Manual" instead of "X.M.P." -- which would reveal the other settings with the disturbingly high Offset Voltage.
I also discovered the limitations of the motherboard's fan ports and fan control. Apparently, the "CHA_FAN1" and "CHA_FAN2" ports will not control PWM fans, even if a PWM fan is connected to the CHA_FAN1 port. For the other systems, these had been fitted with 3-pin fans, and the system would correctly control them. With PWM fans, they just run full bore. Again, I thought initially that there was some damage to the board, until I did some web searches and turned up threads at Tom's Hardware, Overclock.net and other forums discussing this and similar motherboards to show the same frustrating observations.
==== ORIGINAL POST ====
I have a Z68 Gen3 system with an Ivy Bridge 3470 (non-K) processor, which was in process of being configured and re-deployed as a home server. The hardware probably has less than month's time on a usage odometer. It has 16GB of well-tested RAM. This was a project interrupted for a good part of last year, because of a health-care crisis of my aging parent involving her hip-replacement surgery and related issues.
For obvious reasons, or because I want to use the PCIEx16 #1 motherboard slot for a controller card as opposed to dGPU, the BIOS was configured to use the iGPU Intel graphics of the processor. I do not remember the phenomenon I'll describe here as occurring last year when I put the system aside because of our other priorities.
When configured for iGPU and at boot-time, regardless of connection (DVI or HDMI), the system-post display appears on my 27" BenQ HD monitor as if it were posting on a 10" display. The post-time information appears in small print.
I have reset the BIOS, replaced the CMOS battery, tinkered with BIOS settings, used different cables -- but to no avail. There is nothing wrong with the monitor, as I can otherwise test it with other systems.
In order to make the display the right size when entering BIOS, I must go into the monitor's OSD and select "Full" for display mode, which appears to be set to "1:1" when connected to the system in question. "Full" seems to be default when a different system is connected to the monitor. Or, if I wait instead for Windows to boot, the display is properly corrected when the Windows log-in screen appears.
Before I continue with this project, I need to know that the hardware is otherwise reliable for the purpose I've intended for it. It can eventually run "headless," after I've set up the operating system (it is currently configured with Windows 7, to be replaced with 2012 R2 Essentials).
So what is causing my display problem? Is it a symptom of a problem that will emerge later after I've fully configured and deployed the system as planned? is it possibly a problem with the motherboard? Or a problem with the CPU's integrated graphics?
I've also installed a small GT-430 nividia graphics card, after this problem emerged. It robs me of that primary PCIE slot. And of course there is no problem at boot time with the display as experienced with the integrated Intel graphics.
