How to Get 1920x1080 Full HD Resolution From Your Laptop

My laptop is an Acer Aspire 4710 which came with Intel 945 chipset and it has Intel GMA 950 as the GPU (Graphics Processing Unit). A few days ago I tried to connect my laptop to a Full HD LCD monitor with 1920x1080 as the optimum resolution.

Max resolution for Intel GMA 950 is 2048x1536 (Intel website), so I think it's okay to connect it to a Full HD monitor, but after connecting it to my Full HD LCD, I'm not able to select 1920x1080 (this resolution is not showing up) in Intel Graphic Control Panel. Apparently Full HD resolution is disabled on some Intel GPU like GMA 950, But everything is ok now, I'am able to use a custom resolution 1919x1080 for my full HD monitor. If you have the same problem as me, please follow these steps to modify the VGA driver for custom resolutions:

Step 6:
Search for :

[NonEDIDMode_AddSwSettings] HKR,, TotalDTDCount, %REG_DWORD%, 0 ; This shows number of DTDs to be used. ; 0-->Disable the feature.
;Following keys have 20 bytes (18 byte DTD + 2 Byte flags).
HKR,, DTD_1,%REG_BINARY%, 01,1D,80,18,71,1C,16,20,58,2C,1A,00,00,00,00,00,00,86,37,01 ;1920x1080@60...Interlaced

Step 9:

To be continued..... ;)
I have to go now...
I will continue this tutorial as soon as possible

On some laptops/notebooks 1920x1080p is disabled in the BIOS...
In this case we need to add more custom resolution.. For example: 1919x1080

Open (maximize) DTD Calculator window....
Click Calculation tab

DTD CalculatorLarger image, click here

Change H Active Pixels value to 1919
and H End of Blanking Interval value to 2201
(Since we've subtracted 1 pixel, we need to add 1 pixel to the horizontal blanking interval - CMIIW)

DTD CalculatorLarger image, click here

It will automatically change the Calculated DTD value...

Step 10: 
Copy Calculated DTD value to notepad....
And replace all spaces with commas

Step 11:
Back to *.inf file.....
Replace the numbers in yellow with numbers from step 10

Step 12:
Then.. At

HKR,, TotalDTDCount, %REG_DWORD%, 0

Change it to 5

Press Ctrl+S to save the changes....
And custom Intel VGA driver is ready....

You can close DTD calculator, MonInfo, Notepad,.. etc..

Step 12:
Open control panel....
Uninstall original Intel Graphics Accelerator Driver
restart your laptop.....

And then install our custom Intel Graphics Accelerator Driver using Setup.exe
Sometimes I have to install Intel VGA custom driver twice... I don't know why...
Restart your laptop....

UPDATE (10/17/2013): For Windows 8 user: Uninstall the original Intel VGA driver > Restart your laptop >  Press F8 during boot to open Windows 8's startup settings > Select Disable driver signature enforcement > Install the custom Intel VGA driver > Restart > Just like in Windows 7, sometimes you have to install the custom VGA driver twice, so go to startup settings (press F8 during boot) > Install the custom Intel VGA driver > Restart your computer > Done! :)

Step 13:
Connect your Full HD 1080p LCD screen....
And then open Intel VGA Control Panel

Custom resolution on Intel Graphic Control Panel
If 1920x1080 available.. Congratulations! your laptop/computer BIOS supports 1920x1080..
but if not, you may select 1919x1080 as alternative screen resolution for your 1080p LCD screen...

After 1919x1080 resolution applied, go to your LCD screen setup and change the phase setting...

Change phase setting lcd monitor

Or use the auto adjustment feature...

Believe me.. there's no difference between 1919x1080 and 1920x1080... After an auto adjustment....

you can use this tutorial to add custom resolutions for laptop/PC with Intel Chipset G35, G33, G31, G965, GM965, 945G, 945GM, 915G, 915GM
