How to Get 1920x1080 Full HD Resolution From Your Laptop

. Sunday, November 8, 2009

My laptop is Acer Aspire 4710 which came with Intel 945 chipset..... and it has Intel GMA 950 as the GPU (Graphics Processing Unit)...
and a few days ago I try to connect my laptop to a Full HD LCD monitor with 1920x1080 optimum resolution, I read GMA 950 specifications at Intel website and max resolution for my GMA 950 was 2048x1536, so I think it's okay to connect it to a Full HD monitor.... but after connect my Full HD LCD, I'm not able to select 1920x1080 (this resolution not showing up) in Intel Graphic Properties.... :(




but everything is ok now....



What do you do when you’re faced with a "resolution" problem?


1:
Download Monitor Asset Manager (moninfo.exe) here..
http://www.entechtaiwan.com/util/moninfo.shtm

2:
Install MonInfo.....
connect your LCD monitor...
install LCD monitor driver...
open MonInfo Start > All Programs > MonInfo > MonInfo
Select your Full HD 1080p LCD Display ID....






then copy numbers in green... click here for larger picture...


3:
Open notepad, paste that numbers...
then replace all commas with space...
these numbers called DTD, it contains information about monitor optimum resolution.




4:
To make sure that you are select the correct numbers, download DTD calculator here...
install it then open it....


click Reverse Calculation > paste DTD numbers > click Reverse Calculate
optimum resolution will appear on the top left of the DTD calculator window...
if it's not... you may copy-paste the wrong numbers.

now, don't close DTD calculator window, just minimize it...


5:
Download latest VGA driver for your laptop here and don't forget to select .zip version of the driver.
extract it then locate .inf file inside Graphics folder, and double click on it... (open in notepad)

Vista x86 (32 bit) : igdlh.inf
Vista x64 (64 bit) : igdlh64.inf
XP : igxp32.inf


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).

7:
Open (maximize window) DTD calculator...



open Notepad
copy-paste DTD to Notepad.....
and replace all spaces with coma

and minimize DTD calculator window...
(we will need it later)






8:
Replace numbers in green with DTD with comas from step 7

larger image click here



and the result :
(I change ;1920x1080@60...Interlaced to ;1920x1080@60...Non-Interlaced
this is optional, it just "comment")
press Ctrl+S to save changes....

9:

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



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

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

larger 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)


larger image, click here

Calculated DTD value will automatically change..



10:
copy Calculated DTD value to notepad....
and replace all spaces with comma



11:
Back to *.inf file.....
replace numbers in yellow with numbers from step 10

larger image, click here




larger image, click here

(I change ;1920x1080@50...Interlaced to ;1919x1080@59,9...Non-Interlaced
this is optional, it just "comment")

12:
then.. at
HKR,, TotalDTDCount, %REG_DWORD%, 0

change it to 5

HKR,, TotalDTDCount, %REG_DWORD%, 5


larger image, click here
large image, click here


press Ctrl+S to save changes....
and custom Intel VGA driver ready....

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


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

then install our custom Intel Graphics Accelerator Driver using Setup.exe
... btw, sometimes I have to install Intel VGA custom driver twice... I don't know why...
restart your laptop....


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


If 1920x1080 available.. well congratulation! your laptop/computer BIOS support 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 phase setting...




or use auto adjustment feature...


believe me.. there's no difference between 1919x1080 and 1920x1080... after auto adjustment....

notes:
you can use this tutorial for
laptop/PC with Intel Chipset G35, G33, G31, G965, GM965, 945G, 945GM, 915G 915GM
and add more custom resolutions....
Thanks to Archibael :)
