I can do this on any notebook?
Works fine the speed up refresh rate?
Thnks

The patch is only useful if the notebook has a dedicated GPU without switchable graphics, and it's only useful for DVI and HDMI. It would not affect the notebook display.

The patch is for Vista and later only. XP has completely different drivers.

Toasty is it possible to patch XP version of drivers too, or its difficult to realise? For some donation ofcourse.

ToastyX can You help me with my problem? I have weak pc, and no opportunity to buy new one, whats why i still use Windows XP. If i can help You with something, i'll be glad to do it. Thanks in advance.

I tried a long time ago for someone else and didn't have any luck, but that was with much older drivers. I might try again later with newer drivers when I have time, but I won't be able to test it. What limits are you trying to overcome?

It would be nice! Will wait for news=). I'm looking for method to remov pixel clock limit for DVI, to allow higher refresh rates. I use dual-link DVI which was delivered with my Benq XL2430T. I can test it, if You give me instructions what i should to do. Thanks for not forget about me=).

The BenQ XL2430T already supports 144 Hz out of the box with dual-link DVI. What are you trying to do that requires the patch?

The Benq has a hard coded firmware limit of 145hz. You can not exceed this no matter what you try. The panel itself has been able to run up to 240hz if used with different scaler/firmware/electronics (with a lot of image quality degradation).

The Qinx panels use the same physical panel used on VG248QE, XL2411T/XL2420TE, XL2430T, XL2420Z, etc. just the scaler and (naturally the firmware) is different. No refresh rate lock on the firmware.

Hello, I am trying to overclock a SAMSUNG Smart TV, connected via HDMI to the primary of two Gigabyte GTX 970 GPUs. I am using the newest nVidia 358.50 driver and am running Windows 10.
The TV is not very recent, I am guessing it's still using HDMI 1.2.
I cannot, in any way, go over the 165MHz limit. I am wondering if this is the TV's fault, since it's running HDMI 1.2 it can't physically accept an input with a pixel clock higher than 165MHz.
I managed to get the TV to 75Hz using these settings:

Setting the front porch to 0 on both Horizontal and Vertical fields, I can successfully test a resolution with a higher pixel clock, although I can't apply it. I'm not even sure it's displaying more than 60Hz. Maybe, since it's an invalid value, the driver just defaults it to 60Hz.
I also have three other monitors connected if that matters, two 1080p@60Hz ones and an overclocked QNIX (1440p@110Hz).

Is there any setting I can tweak to lover the pixel clock (if that's the issue), or should the TV just work with an higher pixel clock? I have had success overclocking the other three monitors, but they are connected via DVI (no experience with HDMI).
I also own a DP to HDMI adapter, could try that and see if it makes any difference.

What happens when you try to go over 165 MHz? Is the driver not allowing it ("test failed" message) or is the TV not displaying it?

Hardware limits are not exact like that. It's usually possible to go higher than 165 MHz unless there's a new driver limit that I don't know about. If it's a driver limit, 165.00 MHz will work but 165.01 MHz will not. If the TV has a pixel clock limit, it won't be exact like that.

Those values are impossible because the total includes the active + front porch + sync width. It's probably reducing the sync width without telling you.

Technically, 0 front porch values are possible, but the driver might not be handling it correctly. The TV should tell you what refresh rate it's actually receiving in the OSD.

The only way to reduce the pixel clock without reducing the refresh rate is to reduce the totals. The totals include the front porch and sync width, so reducing those might allow you to reduce the totals further.
