Custom Resolution Utility (CRU)

[someone]

i know this program isn't for downsampling, but i'm talking in general: does anyone know a downsampling workaround for unsupported resolutions (black screen) where the aspect ratio isn't the native's one? if it matters, i have an acer aspire a315-22 with an amd gpu where 1366x768 is the native resolution and 1024x800 showed a black screen (despite having 229888 fewer pixels than the native, it has 32 more rows of pixels than the latter). the only thing that worked is vsd (which i tested a few weeks ago and worked)
