REVIEW: Dell 1907FP (s) Part 10
The Dell 1907FP offers no interpolation settings on its own. Resolutions smaller than the native resolution of 1.280 x 1.024 pixels will always be displayed in full screen. For example, selecting the 1.024 x 768 resolution in a game will result in the picture being interpolated to fill the whole screen area. However, this brings about the problem that content appears slightly stretched, since a resolution of 1.024 x 768 translates to an aspect ratio of 4:3 as opposed to the 5:4 aspect ratio of the screen's native resolution.
If, however, the Dell 1907FP is connected to the graphics card via a digital link using a DVI cable, most graphics card drivers allow setting the interpolation behavior. Among these settings is an option that preserves aspect ratio (1:1), so that pictures with resolutions smaller than 1.280 x 1.024 are displayed in their original size, framed by black bars around it.

Overall, the interpolation image quality of the Dell 1907FP is satisfactory. The loss in detail and focus is quite noticeable. In games, this will mostly not be visible unless there is the possibility to directly compare detailed in-game scenes next to each other, i.e. with the native resolution on one side, interpolated on the other.

The Dell 1907FP supports 75Hz in digital mode via DVI. When doing so, the internal panel update frequency runs synchronized with the refresh rate (vertical frequency).
When operating the Dell at 75 Hz while having vertical synchronization (V-Sync) turned on, no tearing effect occurs (i.e. visible split where the old frame overlaps the newly rendered frame). Given that many LCD monitors run at a fixed panel update frequency of 60 Hz, the possibility to operate it at 75 Hz in digital mode sets the Dell 1907FP apart.
As far as DVD playback is concerned, the Dell 1907FP seemed up to the job, effortlessly displaying whatever onscreen action it was served, e.g. fast-paced battle scenes or camera pannings as seen in the movies 'Troy' or 'Password Swordfish'. In none of the tested movies could we detect any occurrences of ghosting.
