ale panove, precte si ten PDF soubor, na ktery jsem sem daval odkaz... je to mozne udelat, samozrejme ze na sekundarnim zarizeni bude obraz prepocitany na dane rozliseni... jen ovladace to musi umoznovat.

jeste jednou odkaz na onen dokument -

Scaling
Each of Avivo’s Display Pipelines has their own independent image output scaler. The purpose of these scalers is to convert the displayed image to the dimensions required by the monitor. This is particularly important for discrete-element displays such as LCD displays which have a ‘native’ resolution at which they work best. This fit-to-display processing can be done by centering, replication, or scaling. These scalers can also utilize these modes in combination in some cases.
The image output scalers support up to 6 vertical filter taps and up to 10 horizontal filter taps. These scalers are high-precision polyphase scalers that are highly programmable; they are suitable for upscaling by practically any ratio, or for downscaling by up to 4:1. Moreover, the scalers flexibly offer vertical scaling independent from horizontal scaling, and vice versa.
It’s noteworthy that Avivo’s downscaling capability is supported on all available interfaces, which is a first on GPUs. This feature is ideal when in cloned mode and the secondary display device, for example a projector, is lower in resolution , than the primary one, such as a notebook; in such a scenario, other display controllers force the higher resolution notebook panel to be displayed at the projector’s lower resolution. With Avivo’s downscaling, the notebook can run at its native,
