GeForce GTX 460 not picking up refresh rate on modern LCD monitors

[sera]

Hi , I have an NVIDIA GeForce GTX 460, and while it has drivers for XP, it does not properly detect my LCD / set the refresh rate properly. Strangely enough, my CRT gets recognized and lets me set the refresh rate freely, though. 

When I do set the refresh rate, Windows says it is running at its proper 144hz, however the display still is updating at only 60hz. I am running it through the HDMI port, and on other versions of Windows (>XP) I do get properly working refresh rate settings.

On the latest driver, it detects it as an SDTV and won't let me add any custom resolutions at all. 

On an older driver, the LCD is detected as an LCD, lets me add custom resolutions, but the refresh rate issue occurs.

Is this issue known at all? Is there a workaround? 

Thanks.

What resolution you try to run on your LCD with 144Hz ? What native resolution of your monitor? What exact model of your monitor?

Trying to run 1920x1080@144. The native resolution of my monitor is 1929x1080@165, however it caps at 144hz on this card. Using Acer XV240Y. 

Also of note with this issue is that the card simply does not pick up any refresh rate higher than 60hz. Seems to cooperate properly with <60hz, though.

I remember about 10 years ago i read about it and now i totally forgot. I was thinking today about this and did not remeber. I do not have 144Hz monitor so i can not test solutions that i read today in internet. So...

Many years ago nvidia drivers have check-mark "Treat as HDTV", which  can be unpicked. But it no longer there perhaps it hidden and needed some reg file to be activated, nvidia did such tricks long time ago with hidden options in drivers. Also i am not sure that would help.

So my idea that you can create an alternative driver for your monitor using 2 methods:

1) Program Monitor Asset Manager (MonInfo) - "App can both read and write data in number of formats. It can also generate INF files, which can be used as custom monitor driver." I assume you can edit that .inf file to add needed refresh rates.

2) Method that i found on some old google cache text:

Quote

We make a display driver (.inf file) with Rivatuner v2.24 and to the column  [Mon.AddReg] add or change the line  HKR,"MODES\1920,1080",Mode1,,"157-170,120-160,+,+".
We put in manual mode and veil of 144 Hz in the list of supported.

I'm sorry i did not find anything else. Only that.

This solution should help the owners of high-res monitors.
