Gigabyte GA-H77N-WIFI

[eric red]

I bought GA-H77N-WIFI to make a small HTPC.
I made a sytem with win7-64 and wanted to connect to LG tv through HDMI.
Unfortunately the system could not be set to display 1920 x 1080 properly.
After many tries and research on internet I learned that LG tv's are NG for PC and they will not display properly on HDMI.
They operate properly on RGB. I bought Asus board with RGB and the system works properly.

I had a spare new motherboard so I decided to update my desktop computer.
After installing win7 64 and drivers from Gigabyte disk , on the reboot there was a message "Interactive logon failure" ?? and then dvi signal would dissapear when windows boot started.
When restarted in safe mode it displays and if I rollback the driver everything is normal.
Reinstalling driver (Intel 4000) from a disk or from windows update will always kill dvi or hdmi on windows bootup.

I reinstalled with win7 32 and win8 , the results are the same.

Otherwise the computer works no problem.
Bios was set to optimized settings.

GA-H77N-WIFI
Cpu i3-3225
8Gb ram
120 ssd
onboard video card.


I contacted Gigabyte on internet and all I get is no response.

Any ideas?

Re: Gigabyte GA-H77N-WIFI

Re: Gigabyte GA-H77N-WIFI

I installed win7 and drivers using dvi ,
later I connected using hdmi results were the same,
although I didn't try to install win7 using hdmi.
My bios is F2, there is also Beta f3 I think but I didnt touch it yet.
Would there be any setting in Bios that could be modified before instalation to make the driver work?

Today I added another hard drive and installed new win7-64 pro.
Before installing I connected monitor with hdmi.
Installation went without a problem,( OS and then drivers from Gigabyte disk).
That was dual boot.
I went to original OS on ssd.
Device manager.
updated the driver.
No problem.
The driver seems to work ok. Windows performance test looks OK.
On restart I had to set sound to monitor.
Windows update came with an error when trying to install intel 4000 driver.
(maybe it saw that it tried to install same driver before without luck)
Conclusion ????
Dvi behaves funny. Time will show how lucky I got.

Thanks for help
