If the track looks like it’s rushing toward you and the same braking marker feels farther away than it should, revisit the field of view. For a single screen, start with two measurements and your normal driving position.
Measure where you actually sit
Sit back as you would during a race. Measure from your eyes to the screen and measure the display’s horizontal width. Check whether the sim wants the width of the visible panel or the full width including the frame. The diagonal size printed on the box is a separate measurement. Enter the values into the sim’s calculator if it has one. If you use an external calculator, match its horizontal or vertical output to the kind of field of view the sim expects.
Give the view a few laps
Drive a familiar track and look at the horizon and your usual braking references. Adjust the camera height or seat offset if the dash or horizon sits awkwardly. Those controls change where the virtual driver sits. Field of view changes how much of the scene the display shows.
A narrow screen at arm’s length can leave the side mirrors out of view. Try bringing the display closer on a suitable mount if you have space and can preserve steering clearance. Measure the distance again after moving it. You can also bind look-left and look-right controls and check which mirror and spotter options the sim provides.
Write down the screen distance and the resulting setting. If you share the cockpit, check the value again when the seat moves a substantial distance.
