The official Philips BDM4065UC thread

the PWM cycling only kicks in if you lower the brightness control below 100, which i expect most people will need to as it's very bright at 100%. From there, the backlight is rapidly switched on and off at 240Hz which is what can lead to eye strain and headaches for some people

hopefully being VA specialists BenQ will use this or a simular panel and implement their low blue light and flicker free technologies. that would make it even more ideal..

all i need then is HDMi 2.0 & DP1.3 for some panel overclocking abilities

You mentioning overclocking abilities reminds me.

I did try OC - to 75Hz. It does work. Sorta.

It has the same issue the Sammy 32 inch VA did when running above its 60Hz though, in that it becomes "juddery" for lack of a better word.

It would be great to be able to run a bit higher, but from my experience with the Sammy, no amount of tweaking timings in any way seemed to improve it.

Or do as someone suggested and lower the brightness in the Pc Control Panel.

Thats what I am doing and works perfectly for me

This compresses the colour gamut range and will certainly clip too, not good for image quality and noticeable Vs just changing brightness if done to any degree more than absolute minimal. Changing the brightness like this to the amount needed to make it a viable brightness control with monitor set to 100% will butcher it.

Ohh, Cheers for the info.

Had no idea.

Thanks mate

I'm not talking from experience here mind, it could be perfect for games where colour isn't really a big deal or day to day use (or it could be awful still). If you're messing about with photos though the results defo won't be good.

doesnt that screw the colour range up though and alter the effective gamma ?

sorry, but id prefer a proper implementation. its good that you have a ( compromised ) work around though. As said, fingers crossed benq has their patented flicker free tech to put into this
 
This monitor looks great. Very tempting.

I know that it can do 4k/60hz with displayport and 4k/30hz with HDMI.

But what about 1080p/1440p? is that still 30hz with HDMI or is it 60hz at those resolutions but 30hz with 4k?

I would like to use this for xbox one/ps4 gaming aswell you see.
 
i can do, but could do with an idea of how best to recreate the issue? the guy there on HF suggests it's gone when switching to the uniformity mode as well

It's quite easy if you have a solid background colour, with say purple (maybe not too dark or light) and open something like a browser window to a site that has a lot of white in it.

Another one is to open the lagom.nl gamma page. This is not white, but has still produced the anomaly for me across the vertical gamma images - I noticed it on my current background which has a very cloudy sky, so a lot of grey.

I noticed the guy said it went away with smart uniformity and your ICC profile, but I was hoping to correct it without using that preset - I have not tried your profile yet, but found that smart uniformity crushes blacks quite severely so avoided it for now.

Plus, this may present itself on other inputs where I won't be able to use a profile, such as console.

I have not done huge amounts of testing across different inputs, etc yet.

Like I said, I can live with it for now, but would like to establish if it's fault or settings issue, etc, so I will know what to go to Philips with down the line.

I can't say I have noticed it in games, nor the couple of movies I have tried.

It apepars to happen only with solid vertical lines of high contrast or some such, so may only appear in desktop use.

It also seems directly proportional to the height of the contrasted area - so a short contrast area vertically won't show it, but a large one will - can be tested by shrinking the size of a browser window.

Edit: wow, that was long-winded! Sorry :D
 
Gibbo, when are these back in stock?

website says ETA is 23rd but as we all know thats not true.

when are they due? i aim to buy one on your finance package on january 1st :)
And one thing i won't be doing is letting my interest free payment time be used up waiting for it to arrive!
 
Yeah, too busy playing dragon age on it when I have any time to spare.

That I play in 16:9, as don't think wider FOV will do much for me.

Looks wicked :)

Can be a bit f a challenge to the 970's though.

damn you.

21:9 is cool and all that but 16:9 on a 40" with the fov slider up a bit isnt exactly a square box :D

on of the reasons that people have been wowed the 34" 21:9 is a lot to do with it being about 32" wide which is loads bigger than the 24" 16:9 most people are used to running. With the philips the width is about 34".

Actually, with the 40 inch, it's actually closer to a 38 inch wide :)

no not diagonally, i mean physical width ( i checked on the philips website before posting ;) )

that link says the same ..

width: 34.86 inches - >> As a 16:9 Display 40.00 inches
Width 31.25 inches - >> As a 21:9 Display @ 34.00 inches

thats the right link :D

correct me if im wrong though.. because now im doubting myself. Either way the 40" is bigger all round and has a higher PPI
