Benq BL3200PT (32" 1440p)

I reckon a proportion of these monitors are clearly faulty as evidenced by these videos. The ARMA 3 one is similar to what I experience in Battlefield 3 but much worse. For £500 this should not be happening.

Other than the flashing (!) ARMA 3 looks ace on your rig. I always played BF3 tactically and from the reviews I have read ARMA 3 takes it to a new level....
 
Have you tried to play around the BF3 graphic settings to see if anything would help on this problem? Lowering resolution, lowering graphic quality, or change refresh rate.

Using a Radeon 290 here.

I've put up a video of my BenQ with Google Earth, and the dead pixel test page on both the BenQ and Samsung 305t+.

My laptop has an NVidia chip in it, if I get time later I'll hook the BenQ up to it and see if there's any difference.

Please do then we can eliminate graphics card as a factor. I have tested it on NVIDIA and Intel.

Yep. It is flawless in all other resolutions. It is really annoying because I find this monitor perfect in every other way - lag is acceptable, ghosting not noticeable, size perfect, stand and adjustability perfect. I also have a 120Hz 27" ASUS so have a reasonable idea what playing at 120fps is like (though for me personally I struggle to tell the difference above around 85Hz). More important is minimum fps so I actually find it smoother to play at 60fps constant rather than have a varying 60fps to 120fps which occurs because my gtx 780 can not drive a high enough minimum fps.
 
Yes, unless I knew for sure that this is not a problem with most of the monitors. Considering it happened on two of yours, I think it may be more common than you'd think. But since it happens only in certain conditions and certain games, many have not come across the issue. Maybe it only happens on Nvidia cards using this particular monitor.

If I knew that it is just a fault with my monitor and not all of the BL3200PTs, I would replace with another one. But otherwise I may just go back to the BL2710PT.

It happens with my laptop which uses an Intel on board gpu I believe. You are correct that many might not notice this flaw. ..I used the monitor for hours - videos, Internet, office, company of heroes 2. Then wondered the world in Google Earth and nearly had an epileptic fit near the summit of K2.

Thought it was just a software bug. Loaded up BF3 and the Caspian Border level had moments when it was like being on the dance floor in a really bad disco.

Out of curiosity, where did you buy yours from?
 
Okay, just tried the Benq with my laptop (a Dell XPS 15 w/ Nvidia 525 graphics) and it works fine, no sign of flickering on Google Earth at all.

My BL3200 is one of the first batch I believe, manufacture date is March 2014.
 
This makes me remember that my Dell U2413 had this issue that it would black screen and came back to normal after 1 second. Also, my old BenQ FP241W would also flash screen randomly (https://www.youtube.com/watch?v=M0Y8CMC5_qI). Both issues were reported by number of people, but still number of people said they were flawless. All these issues are those which only happen on particular combination of graphic cards, monitors, settings.
 
I've found that the flickering problem seems to be related to the Contrast setting in the monitor's OSD. I had it at the default value of 50 on my video. It needs to be below 15 or so to stop the flickering. But of course this makes everything very dim. Turning it up higher than the default seems to cause it to flicker more.

Just to be clear, it is not the flickering within the window but whole screen flickering as a result of moving the window.

Ah. I missed that distinction, sorry. I only see the particular window flickering, not the rest of the screen.
 
I just read comments from a user on another forum here describing the exact same problem with screen flashing on a Samsung S32D850T that Kujen is having on his Benq...

This seems to suggest that it is in fact a defect of this AMVA panel rather than an issue with this monitor in particular.

Ironically, he reports replacing it with Benq BL3200PT and having the problem going away... It might be luck of the draw with avoiding a defective panel at this point or perhaps its an issue with one particular batch. Who knows. In any case i'd probably avoid getting either at this point until this all gets sorted out.

Few people on the forum reported no issue at their side. It might just be a particular batch of panel.
 
Anyone looking to buy one in the UK - Overclockers just dropped the price to £469.99

Unbelievable. Just got the SamsungS32D850T from Amazon and set it up.


The Samsung has exactly the same problem too!!!!!!!!!!!!

So 2 BenQs and 1 Samsung. That's 3 monitors with faults in a row......... I'll post a YouTube clip later.

Annoyed and laughing at the same time.

Same as this guy http://forums.overclockers.com.au/showthread.php?t=1136641&page=4

But that guy replaced the Samsung with a BenQ and his flickering problem went away. So maybe there's a bad batch of panels?

For what it's worth, I was an early BenQ BL3200PT adopter and I haven't noticed any flickering in months of daily use.

Hi. I think you are right. Out of interest have you tried scrolling Google earth where K2 is? Or dragged this window across your screen:

Could you confirm that it is OK on your monitor?

Cheers,

There was a bad batch. I heard from BenQ and they're aware of a flashing problem effecting a very small percentage. They said its due to the back lighting and main board not syncing up. It's something they can replace with an RMA.
 
Crap. I'd seen that effect once or twice and thought it was signs that my video card's RAM was overheating.
Here's a direct linky to the OC forum post which made it easy to recognize:

I was also trying out that GreenMagenta link in more detail. I see the window itself flashing when moved, but not the rest of the screen.
However, it also does some fairly funky things across the entire width of the screen:

Can you provide a link to the source of that statement by BENQ?

To get rid of the flashing problem I tried fiddling with settings and combinations of turning the Sharpness and/or Contrast (as previously stated by another member) down fixes the problem in different games. Arma 3 is the only game I can't seem to get rid of the problem unless I scale the picture down using "display mode".

If I can send it back to BENQ for an RMA I'm scared that I'll get a screen back with the banding issue. I think my monitor is perfect except for the flashing :(

I'm sorry that I cant help with your query but if yours is free from banding do you mind posting the build date of your monitor?

I'm sorry, I don't have a link. I've been communicating with their customer support over email.
 
Can u RMA a used monitor?
Amazon warehouse has the 3200pt pretty cheap and they say "Item is in original packaging, but packaging has damage. All accessories are present and undamaged."
 
Used I would think doesn't come with a warranty, so you wouldn't be able to RMA through the manufacturer. Manufacturer refurbished would. But you could return or exchange through Amazon.
 
Thnx $645 is tempting but ill wait for the bl3201ph maybe those panels wont have branding/flickering

Hi:
I wonder if you do not maximize the google earth, would it still be the case? If you make the window really small, does the problem still exist?

Good suggestion, I have just tried this. It appears there are certain sections on the screen that induces the flicker. The most sensitive area is around the upper right of the screen. No flickering towards the corners.

Here is a clip to show the testing.

https://www.youtube.com/watch?v=a2g0VBYqr4U&list=UUcjbYRzstlS43xWGgJus-1A


I am pretty handy building PCs and general PC hardware but I am ignorant of the technology and workings of monitors.

Anyone know why certain parts of the screen seems to induce the flicker?

Thanks! Mine was July 1st IIRC. Even if they've reduced the banding somewhat I'll be happy to repurchase this monitor , really miss it :(

Looks better in person, I'll find a camera to take a picture as I took this one on my phone.
 
Got mine yesterday and looks like i've got lucky, there is a visible band but only on full screen colours (red and green only) and I had to look for it to find it. Played World of Tanks and Borderlands The Pre Sequel for a few hours last night, watched parts 2 & 3 of Foo Fighters Sonic Highways (very good if you havent watched it yet) and its a joy to use, everything I wanted and more.

After some research I decided to get the BL3200PT, from Amazon (just in case I needed to return it). Manufacturing time is august which was the first thing i checked and I yelled oh crap why not september? :D

My monitor seems faultless, although I havent checked the google map yet.
The "magenta test" is just plain grey with a "fabric" pattern. i checked with other two monitors: on my IPS of the notebook is also perfect, on my old TN is pinkish with some flickering in the upper part. Yes that monitor had horrible color uniformity.

I'm having some issues to calibrate the gamma, though, using Lagom - the side doesn't recognize the resolution and some images are wrong for this reason I believe.

For mine I found that I needed to download the test images and open them that way. It never worked right in the browser. Also I had to adjust the gamma through Nvidia control settings. For some reason adjusting the gamma through the monitors OSD made no visible difference.
 
Does the Benq BL3200PT actually have a noisy power supply like some of the posters suggest? I think someone posted a video earlier of his Benq making clicking sounds.
