[Official] Dell U2713HM: 2560x1440 Semi-Glossy IPS Club - Page 194

post #1931 of 3078
Hmm weird, you'd think there be consistency with the overdrive ghosting at least per batch. It was extremely severe on mine with the link that I posted, the grey boxes showed green trails while scrolling in either direction that even a random person would notice instantly when I asked for a second opinion (without even my pointing out what to look for).

If I hadn't already shipped the monitor back, I would have taken a video of the effect.

Here's my Dell. Running now @ 75Hz but overclocks well to 90Hz+.

Congrats on your U2713HM......thumb.gif

I found on 'desktop' use over clocking actually has frame skipping but could not prove nor disprove it happens when 'gaming' as I've not noticed any up to 90 Hz refresh rate. I'm sure it may be just placebo effect but it seems more fluid....if not then I'm still happy at 60 Hz refresh rate anyway with this monitor which I enjoy it's brilliant colors for any use.

AndyM95 will get you added to the OP.

EDIT: Forgot to ask which revision did you get? On the side of the box or underneath by the S/N # you will see A00 or A01 with month / year. Thanks. smile.gif

I made this post a week or so ago, but this thread is so active that it has been buried and it seems most of you didn't see it:

Interestingly, you can see faint diagonal lines on the A00 panel, which allegedly has fixed the crosshatching. However, these photos were taken pretty much head on, and as many of you know the crosshatching is only visible at an angle (which is why the A01 doesn't have any in those images). It seems like the A00 panels have introduced something new, which may or may not be related to the crosshatching. These lines are much smaller than on the A01, but still noticeable to the naked eye if you look closely.

I have a few more images of these ghosting tests, but they pretty much all indicate the same thing. the A00 has noticeably darker trails from too much overdrive.

These tests were run with the exact same settings each time. The camera was mounted on a tripod and focused on the same area of the screen (I swapped out the screens but kept the same stand). The colors are slightly different because the A00 has a different tint out of the box, and I didn't want to spend the time calibrating it with my Spyder 4 since I was returning it.


In addition to the ghosting (which was what I was primarily comparing), I also noticed VERY small diagonal lines on the NEW A00 panel, not the original A00. The crosshatching is NOT visible on the A01 panel in those images, because the pictures were taken head on (and the A01 and earlier crosshatching is only visible when you are looking at the screen at an angle). However, there ARE small diagonal lines visible on the A00 panel, even though the image was taken head on (in the exact same position as for the A01 panel).

This image is blown up a lot, so the lines on the A00 panel are actually much smaller than the "normal" A01 and earlier crosshatching lines we are used to ( actually took these photos with a telephoto because i was too lazy to switch lenses...). These lines are very faint, and only visible if you click on the images I posted to look at the larger ones. I have even higher resolution images that show the lines even more clearly (the pictures were taken with a 16 MP camera), but I didn't want to upload them because of their size.


Also, in the second set of images you can see that the overdrive ghosting shadow on the A00 panel for the right square is a totally different color than that of the A01 panel (yellow instead of purple).

I can't see the diagonal lines on either of my A00 July panels Mjolnir... actually I can't see the lines in your pics either, all I see is a lot of ghosting.

I see those faints diagonal lines. I have them on my original A00 panel dated Jan13 near the bottom middle. Depending at what distance you are from the screen they tend to blend in.

No, the january panel should look like the a01 panel, not the NEW a00 panel. The january panel should just have normal crosshatching lines, which are larger and only visible off angle.

I have no crosshatching on my Jan '13 A00. I have confirmed by dissasembling and pictures that I have the old panel and I do have those faint lines like the ones in your pictures that I only see head on and not at an angle. I will take pictures to show you.

Update:
Well, I can't get it to show up on my camera the same way and since I only see them sporadically then that's a good thing smile.gif I'm just gonna enjoy my monitor as I finally got it how I wanted it smile.gif

The lines I am talking about are VERY small, like the width of a pixel. You can only see them in the image because it is zoomed in so much. To the naked eye they aren't really even visible; I was just curious as to why they were there.

Took about an hour and they are going to ship out a replacement. They said it would say it is refurbished because it will be opened and checked. Not sure if that makes sense, but I was tired. I'll let you guys know if the BLB is less of an issue on the replacement. Thanks for all the info.
