RE: NVIDIA Pixel Clock Patcher
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. |
