Dell AW2518HF Frame-skipping Test. Is this normal?

Hello everyone,

i wanted to ask you if this is normal that on some photos i can get a "gap" during frame-skipping test. Some of them are straight, in some of the captured photos with my phone i can see some gaps in between - like it depends on the perfect time of making a photo. But If there are lines, they are usually straight/clear without gaps. Is this good? no frame-skipping issue?

Monitor: Dell AlienWare AW2518HF [240hz]

Monitor is set to: G-Sync Compatible via Nvidia and Super Fast Response time (the fastest available)

thanks a lot for help. im going crazy about this:O


@EDIT:

I downloaded random Camera from Google Play (mobile app store) and set ISO to :auto: - since if i changed that to anything else (the lowest is 100 up to 800 value) then i could only see like 1 block/1 square moving or only couple of blocks/squares.

This is what it looks like in fullscreen of this test:

Looks perfect to me. The test lights up the boxes left to right, top to bottom, so the gap you circled is perfectly normal because once the rightmost box has been lit, it goes to the next line in the leftmost box.

Thanks a lot for response, anything i should consider to test furthermore?


Its my 8th unit of Dell AW2518HF. I seeked through so many units... mostly because before all of them had unnaceptable backlight bleeding (yeah on TN panel) that was annoying me. I bought right now monitor from different shop/seller and its almost perfect. So going to keep it, but im checking to be sure if everything is ok.

It's calendar-style sequence. Pretend the grid is like a weird, large calendar (with extremely long weeks bigger than 7 days long, and with many weeks in a month). Left to right, top to bottom. If there's no "calendar-style gaps", you're good!

So, thusly....

Yes, your photographs are correctly taken and there is no frame skipping.

And the more squares the better, because the longer the exposure, the more refresh cycles are captured, and you can more easily determine frameskipping.
