I have a LG 47LG70YD connected to my htpc that has the following configuration:
Motherboard GigaByte GA-H77N-WIFI + Core i3 3220 + 2x 4gb kingston 1600.When connecting the htpc in tv using hdmi cable, I can only select the 1360x768 60hz resolution , if I try to set 1920x1080 60hz the TV image blinks without stopping and a prompt appears stating: "This resolution is not ideal. The optimal resolution is 1360x768. 60hz"I found some resolutions, pixel clocks and refresh rates in the TV manual, but I dont know how to set it;Here the screenshot with the parameters:http://i1032.photobucket.com/albums/a401/birutawow/lgscarlet_zps21c362da.jpg http://i1032.photobucket.com/albums/a401/birutawow/lgscarlet_zps21c362da.jpg

test 1: Using windows 7, the image blinks without stopping and a prompt appears stating: "This resolution is not ideal. The optimal resolution is 1360x768. 60hz". If I try to keep in 1920x1080 60hz the image does not stop flashing
test 2: I tried all refresh rates available in the video settings, but I could not make it work in1920x1024. Maybe I have to create a custom driver. I have a screenshot of the tv manual, but I don't know how to use all this data on the video settings:
http://i1032.photobucket.com/albums/a401/birutawow/lgsc http://i1032.photobucket.com/albums/a401/birutawow/lgsc...
test 3: Tested using XBMCbuntu Live CD and I can set the resolution to full hD.
Using XBMCbuntu Live CD and clicking on INFO button on tv the remote control gives the information that the film is running at 1080/60p
Using windows 7 and clicking on INFO button on tv the remote control gives the information that the film is running at 1360x768/60
Any tip to contruct a custom driver for this TV works in http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&Description=windows+7 windows 7?
test 4: Windows detected as pnp generic monitor. I created a custom driver using powerstrip(using hardware detection) and now windows is detecting as TV LG, but I can't use the full hd resolution yet. Using XBMCbuntu I can set it to full hd, but not using windows. Even on XBMCbuntu, the resolution 1360x768 came as default, but I could switch to 1920x1024 without problems.
Any tip to construct a custom driver for windows with this parameters:http://i1032.photobucket.com/albums/a401/birutawow/lgsc http://i1032.photobucket.com/albums/a401/birutawow/lgsc...
Intel drivers ( in custom resolutions) have more options, but I don't know what are them. Here a SS with intel options:
http://www.intel.com/support/graphics/sb/img/customreso http://www.intel.com/support/graphics/sb/img/customreso...
What are Front Porch (vertical and horizontal), Back Porch (vertical and horizontal), Sync width (vertical and horizontal), Active (vertical and horizontal), Sync Polarity (vertical and horizontal) and Scan Rate (vertical and horizontal)??
Perhaps understanding how to configure these drivers I can set the correct the tv resolution on windows.
Any tip please?

If the TV supports 1920x1080 60hz then you should not be getting any such message as "This resolution is not ideal. The optimal resolution is 1360x768. 60hz"
If you get a message like that, it could be that the system is misreading the EDID of that display, or the EDID is not providing the correct information to the system driver.
Please try using the latest generic driver posted on our web site, driver version 15.31.9.3165(9.18.10.3165). This is available here:
https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Graphics&ProductLine=Desktop+graphics+drivers&ProductProduct=3rd+Generation+Intel%C2%AE+Core%E2%84%A2+Processors+with+Intel%C2%AE+HD+Graphics+2500&ProdId=3711&LineId=1100&FamilyId=39 https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Graphics&ProductLine=Desktop+graphics+drivers&ProductProduct=3rd+Generation+Intel%C2%AE+Core%E2%84%A2+Processors+with+Intel%C2%AE+HD+Graphics+2500&ProdId=3711&LineId=1100&FamilyId=39
You can alternatively test using the previous version 15.31.3.3071(9.17.10.3071), to troubleshoot any compatibility issues of your system and the latest generic driver.
You should also try the latest driver that is provided by your motherboard manufacturer at:
http://www.gigabyte.com/products/product-page.aspx?pid=4338# dl http://www.gigabyte.com/products/product-page.aspx?pid=4338# dl
In addition, test using the latest version of the BIOS posted by Gigabyte at:
http://www.gigabyte.com/products/product-page.aspx?pid=4338# bios http://www.gigabyte.com/products/product-page.aspx?pid=4338# bios
Then, load the latest driver for that monitor display, this is to be provided by the TV manufacturer at:
http://www.lg.com/au/support-product/lg-47LG70YD# http://www.lg.com/au/support-product/lg-47LG70YD#
Test again with another HDMI cable to see if this could be related to this.
You may need to also try using another TV display to confirm that the issue is not the EDID of the TV or the TV itself

I tested all drivers above without success. Just missed update the motherboard BIOS (will do later).
The LG TV drivers page u gave me only has the firmware for it and not drivers for windows: (
Even so, I tried to update the firmware, but I've used the same version.
I believe that the TV drivers are wrong on windows because on Linux worked perfectly. I called LG and an attendant informed me that they do not have drivers for windows 7. Can I get a tutorial how to set this tv in Intel advanced mode control panel (custom resolution)?

That option for custom resolutions is available for your convenience. For information on using tis feature you can refer to the following articles:
http://www.intel.com/support/graphics/sb/cs-029478.htm Graphics — Custom Resolutions & Modes
http://software.intel.com/en-us/articles/custom-resolutions-on-intel-graphics Custom Resolutions on Intel Graphics | Intel® Developer Zone
You may need to try using another display to confirm if the issue is the driver installed or the TV itself being used o Microsoft* Windows* 7 when generic drivers are being used.

I tested on LG 32LH35FD and could select 1920x1080/60. The image of the desktop was slightly larger than the TV screen, but it worked.
If it was a LG 47LG70YD problem, the 1920x1080 resolution does not work on Linux and it works.
I think the generic pnp monitor driver is not working well.

Got some progress here:
Using the TV's menu, I renamed the hdmi input to "PC" and now I can to set the resolution to 1080i, BUT unfortunately if I try to use 60p hz the screen flashes incessantly.
Besides this problem the colors are very "washed" and ugly. The message "wrong resolution" continues beside the windows calendar.
Any tip?

You may need to check with your display manufacturer for the settings you could use when trying to create a custom Video Mode (resolution). The fact that another display works with the same resolution and refresh rate points to an isolated problem with that display configuration not the driver or video controller.
