I would like to know if this is common in the ROG Swift as well. If all of them have these artifacts, that would be too bad. Hopefully it's only an issue in bad panels.

I'm able to create weird streaky patterns using this image: http://www.techmind.org/lcd/dotinv.html in a browser,
it looks fine if it takes up more than 50% of the screen width, but anyhting less, and it turns green and light and dark bands form all the way across the screen.

I think it's safe to say that there is something odd about my panel.

It does the same on mine.

Uh-oh. Perhaps Asus should have delayed this screen a bit more. :( I was going to exchange mine, but it probably won't help. If this affects a large number of screens (all?) it will be expensive for them.

I have a ROG in review and I was new from start there is something wrong going on while gaming. It was difficult to point out, but I think its related to this problem you shown.

Here is my result (compared to QNIX) https://www.youtube.com/watch?v=-8S2KkJ ... e=youtu.be

Does anyone know the name of this error?

That's too bad :-( I was on board for this monitor but looks I might be waiting a bit longer to see if these issues are widespread.

Inversion issues (http://www.testufo.com/inversion -- try the various Inversion tests) are common on many monitors, especially 120Hz monitors. It has happened on the EIZO FG2421 and several other models.



Also try this one in Full Screen mode - http://www.testufo.com/#test=inversion& ... ity2&ppf=5 .... As you adjust the width of the browser window in this full screen version, you may see the location of the color flashing change, as the standard inversion pattern changes. This can cause the disappearance of green color that reappears in a different type of fine inversion pattern; I've seen inversion-pattern-switching behavior occuring on the older ASUS VG278H in the Inversion Uniformity Test on TestUFO, when resizing the window.

It has been an issue that has bedeviled LCDs for a long time (even IPS panels to a lesser extent). It showed up on the BENQ XL2411T, XL2420Z, ASUS VG248QE, EIZO FG2421. However, it did appear that certain monitor models has more intense inversion artifacts. I cannot comment yet on details on the ROG before the review release date, however, I wanted to chime in that inversion artifacts tend to be normal, while some displays may have it more intense inversion artifacts than average.

The above fullscreen test looks HORRIBLE on my 60Hz monitor. The horizontal boxes flash and change color when I scroll; green, then gray, sometimes... pink?

Yes, even many plain 60Hz monitors have pretty nasty inversion artifacts with the TestUFO Inversion tests.

For those not aware, inversion is a technical process to prevent an LCD from image retention (burn-in) - it is explained at www.techmind.org/lcd/index.html#inversion
