Differing GPU Voltages in SLI Mode
When non-identical GPUs are used in SLI mode, they may run at different voltages. This
occurs because the GPU clocks are kept as close as possible, and the clock of the higher
performance GPU is limited by that of the other. One benefit is that the higher
performance GPU saves power by running at slightly reduced voltages.
An end-user gains nothing by attempting to raise the voltage of the higher performance
GPU because its clocks must not exceed those of the other GPU.
Help for Resizing Your HDTV Desktop
After resizing the HDTV desktop, the new custom resolution created is now added to the
list of available resolutions for that display, and also added to the resolution list within
the game or application.
In Release 190 and later drivers, the method for resizing the HDTV desktop has changed
to provide better image quality when applying underscan. This method results in a new
custom resolution being created which needs to be selected from games or applications to
apply the resizing.
In the example displayed in the following screenshot, the underscan has created a new
resolution (1918 × 1065). Although this resolution looks different, it is still in HD format.
