How-to: Dell 2209WA running at 75hz (or 76hz) and information regarding refresh rates


2012-12-18 update: This tweak still works with Windows 8.

To use this on Windows 8 you will need to disable driver signature enforcements. This video will show you how to do it.
After that, right-click the .inf file and select Install.

Now go to:
Device Manager -> Monitor -> Dell 2209wa (or similar name) -> Properties -> Driver -> Update Driver -> Let me pick… -> Dell DELF011 (EDID Override)

Reboot and you’re all set!

Original post follows below

I was surfing around the other day researching screen tearing and how it could be avoided, and stumbled upon a little driver hack that enables a faster refresh rate on this particular monitor. You can do it just as well with third-party applications like PowerStrip, but a native solution is great and enables you to use this higher mode only in games or certain applications, while maintaining the standard 60hz when you are using your computer for other things.

Please divert your eyes to the lower left corner!

So what’s the deal with faster refresh rates?
Faster refresh rates means you will get less screen tearing. It also heightens the response time of the monitor, allowing it to display information faster both normally and if vsync is enabled (going from 16.67 ms to 13.16 in response time.) It is also stated in the official specifications that the 75hz mode is supported.

Does it help?
I was a bit hesitant at first, but it really does! After toying around with it for a bit, the biggest difference turned out to be the timing I got when I  played DJ Max Trilogy; the result was very palpable, but i noticed that almost all games suffer much less from screen tearing while using 76hz.

Wolfenstein (2009) proved to be one of the best examples as it had some horrible tearing issues at 60hz which were all but gone at 76hz.

What if the game/application doesn’t let me select which mode to use or reverts to 60hz?
Many games have flags that you can send when starting it. If they don’t, a third party app might be able to force the refresh rate.

Finished reading? Go ahead and download the fix here:

After unpacking, right-click the file you get and select “Install”. Please note that this fix is only for the Dell 2209WA monitor. Similar fixes may be available for your monitor, Google knows!

This does not alter any drivers you have installed for your graphics card, such as ATI Catalyst or nVidia GeForce.

A footnote regarding 75/76hz difference
I put both 75 and 76hz in the topic because there seems to be little difference between these two values and people use them interchangeably. After applying the driver mod my OSD shows 76hz which seems to work fine. I have not read any reports that this 1hz difference would be a problem.

ATI Catalyst 9.12 fixes DXVA flicker issue on Radeon cards, improves performance!


sean_mcnamara Sean McNamara, now with 100% less annoying flicker.

When I first tried DXVA (DirectX Video Acceleration, a technology to offload the CPU by letting the video card render videos.) on my ATI Radeon HD 5770 I noticed a weird issue that would seem to change the brightness of whatever I was watching in-between shots. An angle change would often mean that the brightness would either hop up or go down a few notches. It’s very hard to explain this phenomenon but it was highly disturbing. I didn’t bother looking into it more so I don’t know if only specific software/OS’es were affected, but what I do know is that after installing the Catalyst 9.12 update I have watched an entire episode of Nip/Tuck without any issues, and so it seems resolved. 🙂 (At least in MPC Home Cinema.)

The 9.12 update also boosts an impressive (“up to”) 9% performance increase in 3DMark Vantage and OpenGL 3.2 extension support.

However, they forgot to fix this.
