Nvidia Custom Freshrate. Fake or Real?

Hey guys I bought a craigslist laptop for 90$ CAD. Dell M6400 (CD2 P8700, Quadro FX 2700M). I was messing around in Nvidia control panel to see what the LCD could push and it was able to hit 115hz but screen looked discolored so going down to 104hz was fine but decided on 100hz.

My question is this actually 100hz fresh rate or fake?

Many laptops of that era were able to overclock from 60hz to 100hz. It was a very common thing for TN panels.
I'm sure if you goggle the panel name (which you can find in HWinfo32/HWinfo64), you can see if others have overclocked it.

The screen on the old MSI 1761 based laptop (GT683 I believe it was called) would also overclock easily to 100hz.

120hz was very difficult if not impossible to achieve on most of these panels.

testufo.com will show you if the refresh rate is working properly.

Note: as a general rule, it's best to use ToastyX Custom Resolution Utility to actually set the custom refresh rate. You can use the NVCP to test it originally, but there have always been issues with using the NVCP to set a custom refresh rate, *IF* ToastyX CRU also works--if both work, always use CRU. There are some games that will actually crash if a custom refresh rate is set in the NVCP, or will refuse to run fullscreen, while they work fine if done with CRU. (This is usually on panels that have native 120hz but have no 60hz entry, which has to be added manually). there are -some- instances where the NVCP is needed and will work while ToastyX CRU won't work (usually some driver shenanigan bugs with extremely high refresh rates set with custom Vertical Total values, with external monitors)
