Vertical Retrace Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Vertical Retrace Time = Horizontal Lines Lost*One Horizontal Time
VRT = L_h*T_h
This formula uses 3 Variables

Variables Used

Vertical Retrace Time - (Measured in Second) - Vertical retrace time a measurement of time related to video displays.
Horizontal Lines Lost - Horizontal lines lost is defined as the number of times per second that a raster-scan video system transmits or displays a complete horizontal line.
One Horizontal Time - (Measured in Second) - One horizontal time is the number of times per second that a raster-scan video system transmits or displays a complete horizontal line.

STEP 1: Convert Input(s) to Base Unit

Horizontal Lines Lost: 20 --> No Conversion Required
One Horizontal Time: 70 Millisecond --> 0.07 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

VRT = L_h*T_h --> 20*0.07

Evaluating ... ...

VRT = 1.4

STEP 3: Convert Result to Output's Unit

1.4 Second -->1400 Millisecond (Check conversion here)

FINAL ANSWER

1400 Millisecond <-- Vertical Retrace Time

(Calculation completed in 00.004 seconds)

Height of Rectangle Picture Frame

Go Height of Rectangle Picture Frame = Width of Rectangle Picture/Aspect Ratio

Width of Rectangle Picture

Go Width of Rectangle Picture = Height of Rectangle Picture Frame*Aspect Ratio

Number of Lines in Frame

Go Number of Lines in Frame = Horizontal Frequency/Number of Frames per Second

Number of Frames Per Sec

Go Number of Frames per Second = Horizontal Frequency/Number of Lines in Frame

Aspect Ratio

Go Aspect Ratio = Width of Rectangle Picture/Height of Rectangle Picture Frame

Horizontal Resolution

Go Horizontal Resolution = Video Bandwidth*(2*One Horizontal Line Scan)

Number of Horizontal Lines Lost during Vertical Retrace

Go Horizontal Lines Lost = Vertical Retrace Time/One Horizontal Time

Vertical Retrace Time

Go Vertical Retrace Time = Horizontal Lines Lost*One Horizontal Time

Kell Factor or Resolution Factor

Go Kell Factor = Horizontal Lines Lost/Number of Lines in Frame

Vertical Resolution (VR)

Go Vertical Resolution = Number of Lines in Frame*Kell Factor

Vertical Retrace Time Formula

Vertical Retrace Time = Horizontal Lines Lost*One Horizontal Time
VRT = L_h*T_h

What is vertical retrace synchronization?

Vertical Synchronization (VSync), helps create stability by synchronizing the image frame rate of your game or application with your display monitor refresh rate. If it's not synchronized, it can cause screen tearing, an effect that causes the image to look glitched or duplicated horizontally across the screen.

How to Calculate Vertical Retrace Time?

Vertical Retrace Time calculator uses Vertical Retrace Time = Horizontal Lines Lost*One Horizontal Time to calculate the Vertical Retrace Time, The Vertical Retrace Time formula is defined as a vertical blanking interval or the vertical sync signal, vertical retrace is a measurement of time related to video displays. Vertical Retrace Time is denoted by VRT symbol.

How to calculate Vertical Retrace Time using this online calculator? To use this online calculator for Vertical Retrace Time, enter Horizontal Lines Lost (L_h) & One Horizontal Time (T_h) and hit the calculate button. Here is how the Vertical Retrace Time calculation can be explained with given input values -> 1.4E+6 = 20*0.07.
