Philips BDM4350UC 43 inch 4K IPS PWM-free monitor

signed up just to reply to this:

overclockers after initially selling at 529, increasing to 559 has suddenly dropped to 499 today as well. for those asking if 1-2 hours is a long time, thing about more obvious things like scrollbars on applications, menus etc. which are likely to be relatively static for a long session. a monitor should be able to go a long long long time without this problem. Hopefully the lg ah-ips panels thats in the dell p4317q will survive better than this. almost twice the price, but if its zero the defects, its worth it.
 
So it looks like these are the ones who haven't encountered any image retention issues (in this thread):

dbgt - 3 weeks+
Raquel - 2 weeks?
morfinx - 1 week

I'll keep testing as time goes on.
 
Well shit, I just order this. Found this thread trying to find more reviews. I'll report in if I have any issues.
 
I have had mine for 3 weeks now. Nothing new to report.
I still haven't noticed any image retention but I haven't been exhaustively testing for it. I still leave random windows open on the black desktop for longer than necessary and periodically shift them around looking for ghosting. I wonder if it is worse if it is a dark window on a bright background? I feel like if I spent a bunch of time playing with brightness, clocking, and modes I might be able to get a clue as to what is causing the burn-in issue but I don't want to risk messing with it while it is working.
Though $800 might seem like a lot it still seems like a "cheap" monitor to me (relative to larger Dell Ultrasharps, etc) so I sort of accepted some minor issues when I settled on it. Though I wouldn't consider the severe image retention some are reporting minor. Basically $550 more for the Dell for a bit brighter back light and a matte screen.
It really worries me that Philips has pulled the product page though. I suspect nearly every one of these monitors is eventually going to have issues. I am just hoping it can be fixed via firmware, or maybe a quick controller board swap.
I really like my setup right now and would hate to have to move back to something smaller. I sit about ~42" back from the monitors (all wall mounted) and they are basically perfectly sized for my field of view. I mounted them so that my eye level is 2/3rds up the screen as I mainly use it for gaming. It might be too large if you are planning to use it fully for work/productivity and want your eye level at the top of the screen as the bottom would be at desk level.

Well, although is pretty "immersive" I have my doubts about using it for gaming because of that ‘juddering’ issue.
From pcmonitors review: "We have spoken with Philips Product Manager Albert Ulfman about the issue. He confirms that there may be a juddering issue, but that in their fairly extensive testing they did not see it as a problem during normal usage. Due to this and the fact the issue is really intrinsic to the panel, this isn’t something that will be fixed by a firmware update or anything like that. The monitor was never specifically designed for gaming (although it can be used for such uses) and the panel used was actually designed for use in TVs where tolerance for such issues is slacker. If a similar panel was designed from the ground up for the rather niche 40”+ monitor market it would add significant cost to the end product."

From what I have read, you can flip the screen 180 deg and tell OSX to flip 180 deg to get RGB pixel orientation. Sounds strange but if you have a VESA mount like I do this would be a simple solution really. With Windows this is obviously a non-issue.

I have Macs, and think you're correct. I have read that flipping the monitor over will fix the problem. But, I would buy a different monitor before I would do that. That's just silly. I don't want the controls at the top, or even to read Philips upside down, or having to deal with it when I want to plugin in a different source, etc., etc.. No way.

I ended up just turning off Font Smoothing and it's working fine.

Hello,

I have Philips 4k Tn monitor. I noticed that what you said. Outside After Effects or Photoshop the image is washed away with weak contrast, even in games. But when I press Reactivate Amd color control in control panel of graphics card, contrast is bumped and the image is much better and more accurate. But I cannot use icc profile of the monitor and settings from graphics at the same time. Now I think that I don't need to use icc profile because the image is similar as on my tv. What is right way to do it?
Click to expand...


Hmm..I think that the wide gamut statement was a mistake that the reviewer made but I am not sure. Nonetheless, with a wide gamut monitor (100% Adobe RGB colorspace coverage) a menu option that allows you to switch to an sRGB profile is needed or else the application has to be able to do this for you. However, if not colors appear oversaturated and not washed away.

I can't say why this is happening to you though. It seems like the wrong color profile is being used.
 
Well my current GTX 680 is only capable of 15 to 24 fps so there is plenty of juddering going on the video card side.
I am hoping a GTX 1080 will manage 50+ in most of the games I am playing (with much higher settings than I am currently using) but I suspect there will still be hitching, tearing, etc with V-Sync off or high latency if it is on. So 1 dropped frame out of every ~180 from the monitor will be virtually impossible to notice. At least that is my theory.
 
Called Philips.dk today, to hear if it was a general issue with the burn in, which it seems it is. He told me he handled the rma's for their screens and he had never heard of the issue, he even said that it sounded direcly stupid of a pc monitor to have burn in, not much help there. Another sad thing was, it didnt seemed he cared or wanted to look into the case and get back to me. Also funny philips remowed the screen from their site, and the employes have no clue about this issue. Guess no 40+ inch this year.

Yeah what's the deal with these guys? Just put in a great gaming / general use panel and capture the entire market, not just a segment. I was seriously ready to drop $1,000 on this monitor. But they fukked it up.

That's odd.. I spoke with Philips.dk last month, and they told me that they have had a lot of complaints with this panel, and that burn-in was a general issue.
"Luckily" I bought mine via DustinHome, I RMA'ed it the 3d may and FIRST today I received a email that my money was refunded (So f-ing slow!).

Although they already know that something went wrong during the manufacture process and every panel will surely degrade over time, Philips guys probably remain silent until the total stock is sold or returned.

Clearly, nobody removes the flagship product in catalog if there were no good reason for it. This is not a matter of a "faulty batch" or "small issues" but something more serious.

Yes i read that post, also why i found it strange they didnt now.
 
I dont have burn in issues although my first Philips 43 inch had some dust under the screen so i returned that one
The 2nd one i got no burn in aswell. ( tested for longer priods of time ) with the image retention tests aswell as testing it with my browser on a black background and vice versa.
All in all i like it better than the BDM4065UC that i had before( issues were random reverts to 30Hrz ingame aswell as desktop usage ) the gamma shift and the very bad pixel respons time. I also had the Iiyama X4071UHSU-B1 although i had other issues with this panel aswell ( thing was to blue )even after callibrating
Will keep my eyes on the burn in issues and will update here if i see it appear.

I don't think that's right. There is only 1 data point for degrading over time, and that is Lender. Everyone else either has problems immediately, or has not yet experienced the problem. None of the 4 reviewers on Amazon have reported any burn-in issues.

That's the more disconcerting part. Right now it's wait and see.

Anyway, I played some Fallout 4: Far Harbor last night and that worked great, other than the fact that my GPU is not stout enough to run it at 4K so I had to run it at 2560x1440. Also did some work on it, and still no burn-in.

2 data points. Mine is getting worse. None at the beginning, then it took 6h, 2-3h to create image retention. Now about 15 min is sufficient.
 
Maybe Philips has innovated a new concept of burn-in.

Hard to say, because no one will dare to mistreat a new monitor with extensive testing for hours or days as it could void the warranty.

The manual specifically says burn in, particular permanent damage of this nature, is NOT covered, so yeah...not something most people are going to be willing to gamble $1000 experimenting with. To me that's also an indication they knew this was an issue but put it on market anyway... fun.

This was the reason I had to send my monitor back for a refund and not an exchange. Philips appeared to take no responsibility for the assuredly known issue. If it weren't known, why would it have a OSD about it, and be mentioned a ton in the manual about their non-responsibility? I was not going to gamble with my money that way and I can no longer recommend it to anyone either. Unfortunate but true.

Also, I don't understand how Dell is almost following the same path on their monitor? Inspires zero confidence from my perspective.

It's even more perplexing with the Dell because it is specifically advertised for productivity and presentation purposes. One of the promotional photos shows stock market data on the screen. If you're going to be watching the markets with this monitor those images are going to get stuck permanently on there after an entire business day. Selling a computer monitor knowingly with burn-in issues is completely unacceptable.

I don't think it's a coincidence. Some part was manufactured in the same place.
 
Yep was so close to buying it. Had it in my cart at one point but decided to look into the burn in more and turned out to be a much bigger issue than I first thought.

Such a pity because it was close to being a great monitor. It was such a good price in my country that I could have overlooked a few troubles, but burn in.... ugh

Maybe they'll do a version 2 once they've sorted it out
 
I was wondering if it is possible that someone write a program that runs a small circle of colors that would sweep through the screen, left to right, top to bottom, it would be a small circle so it would not be too distracting or get in the way of work, but it would run continuously. That would prevent a static image from staying in any one part of the screen for too long. And then voila, no more burn-in and problem is solved.

I guess you could, but why? That is not acceptable to me. No burn in or no money and I'm sticking to it.

That's what the OSD 'pixel orbiting' is supposed to do really, but judging from this thread doesn't actually stop burn-in.

So this and the dell have burn in, the wasabi mango looks to have significant input lag mentioned over in it's thread.. are we just SOL on 40+" 4k options then? maybe computex will give some hope
 
I've had this monitor for over 3 weeks and haven't noticed any issues with burn in. I went through 3 different screens however and every one of them had a fault in the panel around the same area. In every panel I tested this anomaly existed on the left hand side, bottom region of the screen in varying degrees of severity. The current model I have still has it but it is tiny in comparison to the original monitor that had it spread out over around 2-3 inches of the screen. I've attached a picture to illustrate.

Perhaps this issue contributed to Phillips pulling the model..

The 40 inch still seems to be available for sale, wonder why they didn't pull both.

This is excellent news!

I highly doubt they'll completely pull the product, so hopefully they'll fix the problem and re-release.

I suspect the problem is likely due to some coating applied to the screen in the later stages of manufacturing, and they probably skimped or otherwise had problems there. So no firmware or controller board replacement will fix it. That layer of the panel will need to be replaced.

Just a theory... ;)

I never heard any reports of burn-in on the Seiki SM40UNP. What about the Crossover 434k? Also, is the Dell confirmed to have burn in?

The 40" panels are VA, whilst the BDM4350UC and the Dell P4317Q are both IPS panels - this first of their kind at this size I think. Despite both panels being exactly the same size, the Philips is meant to be one from a parent company manufacturer, whilst the Dell is meant to be LG AH-IPS panel but I've never taken one apart (due to lack of owning one) to find out exactly who makes what.

Despite the alleged difference in the panels, the fact their sizes are identical (and I mean, the visible height, width and diagonal are exactly the same) and they both have the same defect showing, I believe that they are the same panels. Although why Dell would put it through R&D/mftr without spotting this and saying "stop" is astounding.

edit: also yes, first owners of the dell panels have uploaded photos already of burn in happening within 15 minutes of switch on.
