Acer XB252Q sharpness problem ??

[gabethomas]

Hi !

I got my new Acer XB252Q monitor. That is problem if my 14 year old LG(TN panel, FULL HD) 10x more sharpness as this Acer ????
Today 3 people asked as "why not sharpness as a normal LCD ? "

Hmmm -
This looks like a very bad case of stationary inversion artifacts.

Do you see major color distortions at http://www.testufo.com/inversion ?
And some weird effects at http://www.lagom.nl/lcd-test/inversion.php ?

There might be a case for an RMA since such intense visibility of vertical lines artifacts during stationary images suggests a potential defect.

For most panels, the inversion artifacts are only visible with motion, or not at all. (Fine moving 1-pixel-thick lines is an LCD Inversion artifact). But if the lines are stationary during stationary images, there could be a problem.

(They're not visible at all on my ViewSonic XG2530, which is very good in that it has practically nil inversion artifacts at all)

First Thank you so much as you helping me !

At the first link :
The moving box a little bit darker gray, with "dirty" white lines. THe background is barred and sides are scrapy.
Stationary: little whiter gray with dark and gray lines. THe background is barred and sides are scrapy.

The worst part is ( sorry for the stupid example, but this is the best way ) if I open facebook--> right side name list is totally different as on my old 60hz LCD monitor. Like totally lost the sharpness. I need to get closer to see a friend mini avatar picture. (and my eyes are not bad, coz my job is testing luxury sport cars, so every year I have very high medical examinations.

So what I need to do ? I have 14 days to change another product or I can get back my money. First I thinked I will get back to the shop and for little plus money I get a PG258Q, but I dont know it will be better ? I'm afraid not.

Warranty replacement.

There seems to be a defect with this monitor.

I have an Acer XB252Q here (the same one Jorim tested in GSYNC 101) and it doesn't have the same problem.
