IT Home September 29th news Apple Watch Ultra has the largest display on Apple Watch to date, but uses the same display technology as previous models. Apple Watch Ultra has been launched and delivered to customers, and some users have noticed the so-called "jelly screen" scrolling problem on the display of the watch.

iPhoneSoft report pointed out that there is a "jelly rolling" problem on the Apple Watch Ultra. "Jelly Roll" means that half of the display screen refreshes significantly slower than the other half, and will produce a jitter effect when the content moves quickly. Users may see this when quickly scrolling lists or quickly scrolling web pages in Apple's Safari browser.

There was also a "jelly screen" problem on iPad mini 6 a year ago. Despite users' complaints, Apple issued a statement saying that this scrolling effect is "normal behavior". This includes the displays used in the iPad mini 6, iPad Air 5, and Apple Watch.

IT Home learned that Apple previously responded that this is a normal behavior of LCD screens. Since these screens will refresh line by line, this will cause a delay problem between the rows at the top and the rows at the bottom of the screen, which will lead to the "jelly scroll" effect .

On the Apple Watch Ultra, "Jelly Scroll" can be seen in similar situations to the iPad mini 6. For example, iPhoneSoft shows the shaking effect that occurs when they scroll the list with a digital crown. There are also some dispersed complaints about the Apple Watch Ultra "Jelly Screen" on

Reddit, but so far, the number of complaints is relatively small - especially compared to last year's iPad mini 6.

Why is the "Jelly Screen" effect on the Apple Watch Ultra more obvious than other Apple Watch models? The 9to5 Mac says this might boil down to: The Apple Watch Ultra display is larger and brighter than other Apple Watch models. This all makes the "Jelly Screen" more pronounced than the standard Apple Watch model.

Apple has not yet responded to the Apple Watch Ultra "jelly screen" problem. It should be noted that the Apple Watch Ultra uses an OLED screen, while the iPad mini 6 uses an LCD screen.
