In most cases, you won’t notice any prominent ghosting/trailing behind fast-moving objects even with overdrive set to Off or Low, but the Medium/Normal setting will usually work best. Now, if you have a modern LED-backlight 60Hz/75Hz monitor, it’s highly unlikely that its response time is slower than the display’s refresh cycle. Some monitors will also have the option to turn the overdrive completely off. ASUS’ TraceFree option allows you to adjust the overdrive from 0 to 100 in increments of 20, for example. Generally, the levels are labeled as Slow, Normal, Fast, Faster - Low, Medium, High, Highest or simply by numbers. Depending on the model, the overdrive levels will be named differently and some monitors may have more levels than others. There should be at least a few options to choose from. To access the monitor’s overdrive settings, open the OSD (On-Screen Display) menu and look for the overdrive option, it’s usually under one of the following names: TraceFree (some ASUS monitors), Rampage Response, Overdrive, OD, or simply Response Time. Which Response Time Overdrive Option To Use? This is where the response time overdrive, sometimes also referred to as RTC (Response Time Compensation), comes into play to push the pixels to transition from one color to another more quickly. If a monitor’s response time is slower than that - meaning that a pixel takes longer than 16.67ms to change, it will continue changing in the next frame, and that’s how you get visible trailing behind moving objects on the screen.įor a 144Hz monitor, the refresh cycle is 6.94ms, so the response time needs to be faster than that, and so on. You can visit our ‘ What Does Monitor Response Time Mean?’ article for a more detailed explanation but in short, a monitor’s response time speed indicates how fast a pixel can change from one color to another.įor instance, a 60Hz monitor refreshes the image 60 times per second, so there are 16.67 milliseconds between two refresh cycles.
In order to explain what response time overdrive is on a monitor, we’ll first cover what the response time speed is. You will find your monitor’s overdrive settings in its OSD (On-Screen Display) menu, usually under one of the following names: Overdrive, OD, Response Time, TraceFree, or something similar. Thus, the EM impactor and refined surgical and behavioral testing techniques may offer a reliable and convenient framework for preclinical TBI research involving mice.Response time overdrive allows you to push the monitor’s response time speed (pixel transition time) in order to decrease the trailing/ghosting artifacts behind fast-moving objects.ĭepending on the refresh rate, too strong overdrive can cause pixel overshoot or inverse ghosting. Behaviorally, we found that we could statistically distinguish between injury depths differing by 0.5 mm using 12 mice per group and between injury depths differing by 1.0 mm with 7–8 mice per group. Inter-operator reliability was very good. No differences were found between sexes of mice. No impairment of conditioned fear performance was detected. Rotorod and visible platform water maze deficits were also found following 2.5- and 3.0-mm impacts.
Behaviorally, 2.0-, 2.5-, and 3.0-mm impacts impaired hidden platform and probe trial water maze performance, whereas 1.5-mm impacts did not. Histologically, 2.0-mm impact depth injuries produced by the EM device were similar to 1.0-mm impact depth injuries produced by a commercially available pneumatic device. By varying the depth of impact between 1.0 and 3.0 mm, we found that the EM device was capable of producing a broad range of injury severities. With this in mind, we developed and characterized a prototype electromagnetic (EM) controlled cortical impact device along with refined surgical and behavioral testing techniques. Experimental methods that minimize the number of mice needed may increase the pace of discovery. Genetically modified mice represent useful tools for traumatic brain injury (TBI) research and attractive preclinical models for the development of novel therapeutics.
