Blur Busters Forums

I recently got my new xg2431 240hz monitor. I noticed these thick lines on the monitor, mostly visible on bright background. Any way to fix this or is the display broken?

The video is only showing the Moire Effect (camera sensor versus pixel grid) which I don't think is what you're referring to;

Can you pre-focus your smartphone camera to a fixed focal plane (e.g. tap-and-hold to focus on some Windows icons), and then try again with a new video upload?

Hello, I referred to the thick horizontal and vertical lines, almost making an "H" shape. Here is another video where I point at the marks on the monitor

Can you do me a favour, and playback the video again, and screenshot the specific frame?

1. On my end, the YouTube blurry-compression is hiding a lot -- can you play back the YouTube and tell me if you still see it when you play via the YouTube website in a web browser?

2. You still have the original video file, maybe can you screenshot a single original (pre-YouTube-upload) on your end? And attach as an uncompressed PNG file, I might be able to finally see it.

Can you confirm you see it first (post-screenshotted and saved), before attaching;

(YouTube compression = It looks worse on my end than your end, so some picture is being degraded when I play back the YouTube)

Hey, apologies for the YouTube quality. Here are some pictures I took with my cellphone with different background colours. Cellphone makes it harder to capture it but it can be seen with the naked eye. Remember the lines are not dust or marks, they seem to be within the screen. I'm not sure if its a defect in the monitor

I see it now finally -- thanks!

The pictures made it through to my eyes undegraded.

(the photo you upload is the photo I see at its exact quality you uploaded, without YouTube compression unpredictability)

So, on that note, that seems to be a possible defect -- BUT, can you confirm if you also see it in a black screen? Launch a full black screen -- and take a long-exposure photo of it. This will help me decide whether it's temporary or permanent.

Is this exactly in the screen center? If so, it might be a rear bracket pressure spot. 50-50 chance this is temporary, and 50-50 chance this is permanent.

Try running it 24/7 without a screensaver at 100% brightness for a while. It might also simply be a box pressure spot (e.g. box was stored horizontally, or shipped horizontally) from the weight of the monitor's bracket pushing on the screen. Like fingers pressing on screen on steroids. This may take many hours to fade.

You know how when you press a finger on an LCD, the screen artifacts a bit around the finger?

Same thing, except it's the monitor's casing/bracket behind the LCD pressing on it during storage (box wasn't stored/shipped vertically, etc). Those can take a few days to disappear. Since it was like a finger pressing on the screen for a long time, it takes longer to recover from longer pressure.

Mind your convenient return/exchange window (e.g. Amazon easy returns).

I've tried to take some wider shots with a few shades of grey so you can get an idea of where it is on the screen. It does not appear in a pitch-black background or when it's turned off. I see an "H" shape, the left part of "H" is dim and really difficult to get captured by a cellphone, and the right side and the middle is relatively easier. When I reach out to feel it, it feels like it's within the monitor and not the screen, like a layer behind the front layer. I also tried to rub it off with a soft cloth but no result. I've attached some of the images.

As per your suggestion, I will try to run it for a day with 100% brightness.

Have you experienced anything as such before?
Would you suggest I return the monitor?

The forum limits attachments to three so I've linked to the uploaded images instead. I hope the quality is the same

Although hard to see in pitch black background, the camera does capture the shape in blacks.

This is further evidence this is a pressure-spot. Do not try to wipe the screen; that won't help (and if you're aggressive about it, might make it worse if you press on the screen, squeezing it even harder against the rear monitor-mount bracket). The problem is coming from behind the glass.

Yes, try break-in period. The standard break-in period is roughly ~100 hours -- reviewers do it before testing the screens. But if this is a pressure spot from the monitor's screen rear mountings, you should see it fade slightly over just 24 hours. If that happens, keep running it longer, and see how much it fades away. Brighten backlight to 100% and disable your blank-screensaver and disable your computer sleep temporarily, to keep the monitor running continuously. You can get the monitor to do something (run a screensaver animation).

Just make sure to temporarily configure
1. Windows Search Box -> "Edit Power Plan" -> set all items to "Never"
2. Screen Saver Settings -> If you want to get your computer busy doing an animation (optional)

If it doesn't solve the problem, then you definitely should consider RMA. Use the still-images for your warranty claim to ViewSonic (that's their responsibility). Keep in mind Blur Busters is the certifier of the blur reduction feature, as AMD is the certifier of FreeSync and NVIDIA is the certifier of G-SYNC. The manufacturer is still responsible for the warranty.

To speed up break-in period, it is also best to display darker images (e.g. "Ribbons" screen saver or playing a rainy-night YouTube loop), the darker images / LCD blacks helps absorb more light. LCDs heat up more with dark images than bright images because of the light absorption. Higher heat and temperatures lowers the viscosity of the liquid crystals, and speed up the liquid reflow between the glass layers (in the "LIQUID" part of Liquid Crystal Display = L.C.D.)

Once you're done with your break-in period, don't forget to reset your power plan settings, to give mercy to your electricity bill.

Thank you. I will do the steps you mentioned and give it a go today. Will post an update tomorrow
