How to add a custom HDTV resolution to INF


goliath

Recommended Posts

I must be getting thick in my old age!

Could someone please point me to an INF that has 1024x576 HDTV resolution included or how to add it myself. I can see how to add to the Resolution Table section but do I have to add it to the HDTVModes section too? It looks weird. What is with the 8032, C032 etc?

There are a number of ways to do it, here's the easiest

just scroll to the resolution table (under [nv_software settings]) and add to this line:

HKR,, NV_Modes,  %REG_MULTI_SZ%, "{*}S 320x200 320x240 400x300 480x360 512x384 640x350 640x400 640x480 720x400 720x480 720x576 768x576 852x480 853x480 854x480 864x480=1FFF;"

Add 1024x576 so it looks like this:

HKR,, NV_Modes,  %REG_MULTI_SZ%, "{*}S 320x200 320x240 400x300 480x360 512x384 640x350 640x400 640x480 720x400 720x480 720x576 768x576 852x480 853x480 854x480 864x480 1024x576=1FFF;"

Hey thanks for the replies!

Dox:

Well I'm half way there. I got the new resolution in there but it comes up as 60Hz instead of 50Hz. 576p is a PAL standard. 720x576 appears as 50Hz OK and works on the TV but 1024x576 @ 60Hz will not work. Any ideas about how to make it come up as 50Hz?

wook:

yeah I know its not HD but its still used here in Australia and its the only progressive resolution my widescreen Panasonic TV will accept :-(

find this line in the inf:

;HDTVModes_AddReg

HKR,, DisableHDTVRes, %REG_DWORD%, 0

HKR,, NV_HDTVModes, %REG_MULTI_SZ%, "{*}S 720x480 1280x720=1;720x480 1920x1080=C03C;720x576 1280x720=8032;720x576 1920x1080=C032;1176x664=1;1176x664=8032;1768x992=C032;1768x992=C03C;"

HKR,, NV_HDTVModesFRR, %REG_MULTI_SZ%, "{*}S 720x480 1280x720=1;720x480=C03C;1176x664 1768x992=1;1768x992=C032;1768x992=C03C;"

and add change it to this:

;HDTVModes_AddReg

HKR,, DisableHDTVRes, %REG_DWORD%, 0

HKR,, NV_HDTVModes, %REG_MULTI_SZ%, "{*}S 720x480 1280x720=1;720x480 1920x1080=C03C;720x576 1024x576 1280x720=8032;720x576 1024x576 1920x1080=C032;1176x664=1;1176x664=8032;1768x992=C032;1768x992=C03C;"

HKR,, NV_HDTVModesFRR, %REG_MULTI_SZ%, "{*}S 720x480 1280x720=1;720x480=C03C;1176x664 1768x992=1;1768x992=C032;1768x992=C03C;"

i think thats it, reinstall the driver and reboot.

Thank you Dox for your suggestion

I tried that but no change. I can select 1024x576 from the List All Modes list but I still only get 59Hz and 60Hz options. Do you know what the 8032 and C032 numbers mean?

If you are sure that the settings you gave should work I will keep playing around with it.

8032 = custom refresh rate set to 50 hz

c032 = I'm not 100% sure but I do know the 032 in hexadecimal is 50.

maybe your TV only supports the modes that works for you?

No the TV will run at 1024x576 @ 50Hz if it can be fed the correct signal. What good is a widescreen TV that only runs at 4:3 resolutions?

I guess there are 4:3 HDTVs around but not many nowadays!. I have to convince the driver I have a 16:9 display plugged in. I am seeing a 4:3 shaped HDTV icon in the contol panel. I wonder if that is relevant. Should I be seeing a 16:9 shaped icon for the HDTV?

The HDTV modes that you can choose from "Change the signal or HD Format" in the control panel only list the vertical resolution e.g.

1080i50 HDTV

720p50 HDTV

1080i HDTV

720p HDTV

576p EDTV

480p EDTV

You can't choose the horizontal resolution. You just get what it gives you, which in my case is the wrong one.

Thanks for your assistance Dox!

you welcome,

if you are using pieter's inf then thats the resolution you are stuck with.

I've written a guide on how to add your own resolutions or make your own resolutions :)

In it it tells you how to add horizontal resolutions.

ohh and i forgot to mention unfortunately i cannot use the newest drivers with HDTV settings and such because im on a 8600M GT and it will not detect my Tv with HDMI->DVI with the new drivers for some reason so im stuck using the manufactured drivers but i personally changed some of the .inf stuff however like i stated earlier i am unable to locate where the so called "generic non-pnp" monitor resolutions are stored.

actually after further investigation into windows .inf i have located what appears to be the file those resolutions are pulled from but now i am perplexed because there are quite a few of the same file and they all have ALOT of resolutions in there .... so so confusing i think ill stop here and get some help.

the file is called monitor.inf just do a windows search for it and u will find a few copies.
