AMD/ATI Pixel Clock Patcher | nvidia Pixel Clock Patcher

Para los nuevos monitores ultrapanoramicos [UWS] de relacion 21:9 se presentan algunos problemas cuando trabajan a mas de 60Hz [frecuencia vertical], debido a una limitacion impuesta en el estandar DVI y HDMI para la frecuencia horizontal.

Aqui notamos, en color rosa, esas limitaciones, donde para los 2560x1080 solo se puede tener a 60Hz, pero si el monitor 21:9 usa 70/75Hz inmediatamente el controlador de video limita la resolucion a 1920x1080.

Por suerte, al menos para las radeon hay un parche que quita dicha limitacion. El parche puede aplicar los cambios, o bien restaurar al estado original dejando todas las restricciones que venian. Ademas de aumentar el PIXEL CLOCK quita otras limitaciones de paso.



AMD/ATI Pixel Clock Patcher

MD/ATI Pixel Clock Patcher modifies the AMD/ATI video driver to allow higher resolutions and refresh rates by removing the 165 MHz pixel clock limit for single-link DVI and HDMI, the 330 MHz limit for dual-link DVI, and the 400 MHz limit for VGA.

Requirements:
- Windows Vista or later
- 5000-series GPU or newer
- CrossFire requirements:
* R9 285/290/290X/295X2 and newer cards can handle higher pixel clocks without CrossFire bridges.
* Older cards require two CrossFire bridges if the pixel clock is greater than 300 MHz. This is only possible with cards that have two connectors. It will not work properly with more than two cards. Dual-GPU cards such as the 7990 will not work properly at higher pixel clocks.


Compatibility:
Version 1.4.5 is compatible with Catalyst 11.9 to Crimson 17.8.2. It can be used with future versions if it finds the limits you need.


Getting started:
1. Run atikmdag-patcher.exe.
2. If all limits are found, click "Yes" to patch and sign. If a limit is not found or if multiple matches are found, the patcher needs to be updated.
3. Reboot.

You can then add higher refresh rates using Custom Resolution Utility (CRU).

To restore the unpatched driver, run the patcher again and click "Yes" to restore from backup.


Known issues:
- Legacy drivers may have issues with HDCP and video acceleration with the patch.
- Workarounds for video playback issues with legacy drivers:
* Disable hardware acceleration in the Flash Player settings (right-click on any Flash video and click "Settings...").
* Use the Codec Tweak Tool to disable DXVA hardware acceleration under "Various Tweaks" (in the "Miscellaneous" section).

- AMD/ATI cards have a design limitation unrelated to the patch that causes video acceleration to scramble the screen if the vertical blanking/total is below standard with the video card's memory overclocked or with multiple monitors connected. Skype is known to trigger this problem. Either don't overclock the video card's memory, or use the "LCD standard" vertical blanking/total in CRU.

- AMD/ATI cards require the "LCD standard" vertical blanking/total to reduce the memory clock when idle. Horizontal values can still be reduced if necessary.

Así llevé mi pantalla 60Hz hasta los 79.
EXCELENTE, asi ya solo faltaria para intel y su iGP HD graphics.
Gracias a ambos por el aporte. [oki]
Nueva version, liberada este mes de ciciembre 2017 y compatible cdon la ultima version de Crimson Adrenalin en el caso de RTG|AMD Radeon.
Removido nuevo limite encontrado para el HDMI y DVI.
La version 1.4.6 de las Radeon tambien funciona en los ultimos controladores Adrenalin

La version 1.4.3 de las geforce funciona confirmado en los controladores 397.55. Con versiones mas recientes del controlador gforce falta la onfirmacion, pero deberia seguir funcionando.
