Subject: [PATCH] video: Select the closest mode for the target refresh rate
accounting for small variations
Use the delta of the target refresh rate and the refresh rate of the mode to select the closest matching display mode, as the actual closest mode may have a slightly lower rate than the target by a small fraction of a hz (e.g 59.98 vs 60.0).
