@Tup3x PWM is used for backlight dimming it has nothing to do with vertical refresh rate 60/75Hz.

@sblantipodi Yes i disabled eco-view. Your monitor S2433WFS has ccfl-backlight not LED so flickering is not noticable even for me. Only LED displays have this aggressive PWM flickering because LEDs react faster than CCFLs. -> flicker test: http://hardforum.com/showthread.php?t=1646980 Info...

most modern LED displays suffer from that, but a lot of people don´t realize PWM flickering... for me it´s very annoying because my eyes get tired very fast... you have to try it yourself to find out if it´s a problem for you too.

yes...but i have sent it back. It has very very good picture, very sharp, very good colors, very light AG-coating, very good illumination ...but the LED backlight is flickering (PWM). Not everybody can see it but if you are sensible to it it will strain your eyes... For me it´s the best...

very good (german) review online! http://www.hardwareluxx.de/community/f111/hp-zr2440w-850609.html

Currently only one (the first) PWM-Test ist online (as preview) for that display: http://www.prad.de/new/monitore/test/2011/test-hp-compaq-le2202x.html but here is some info about PWM flickering: http://www.prad.de/new/monitore/specials/backlight.html...

Many people don´t notice it - but there are also many getting eyestrain or headache. Maybe tftcentral-testers are not sensible to PWM-flickering www.prad.de includes a PWM-flickering test in all new reviews.. it is a big issue for many people - believe me. this guy also tests it...

really strange... i never saw this effect on CCFL monitors. Normally CCFL reacts too slow that PWM can cause visible flickering. Maybe the Samsung doesn´t use PWM for dimming - some (very few) LED monitors use backlight dimming by reducing the power. The ZR2740w doesn´t flicker too (regarding...

Unfortunately it does! Someone on www.amazon.de made the finger-test with the U2412M and confirmed a stroboscope effect at lower brightness settings. A guy on prad.de posted something about eye-strain with the ZR2440w - he thinks it´s caused by IPS-technology but i think it´s caused by...

http://h18004.www1.hp.com/products/quickspecs/14145_na/14145_na.pdf HP says the ZR2440w supports up to 16,7 million colors (** With the use of FRC technology) -> so its 6-bit+FRC like most actual e-IPS panels... You will not see any difference between true 8-bit and 6-bit+FRC...

1097mm = 1,097m ~ 1,1m

Hi, i´d like to know what´s your seat pitch to your 27" display (resolution: 2560 x 1440)? A German certificate for e.g. HP ZR2740w says it should be 1,097m. http://666kb.com/i/byfimqmdwjclp4vpd.gif

very nice - thanks for info! found a 1st short review here: http://compreviews.about.com/od/monitors/fr/HP-ZR2440w.htm

i hope there will be reviews soon... http://www.prad.de is testing this display currently. They say that the ZR2740w is one of the rare models with completely flickerfree LED backlight - i hope ZR2440w is flickerfree too ! For those of you speaking german (or are able to use...

Hi, please tell your experiences about PWM-flickering in this thread. Here is some info: PWM (pulse width modulation) is used for dimming the backlight. Because LEDs react very quickly this technique can cause flickering (if the PWM module is cheap/poor). Some people can see it - some not...

maybe it´s caused by PWM-flickering... PWM (pulse width modulation) is used for dimming the backlight. Because LEDs react very quickly this technique can cause flickering. Some people can see it - some not. TEST: 1) Open a program with white background (e.g. Microsoft Word) 2) Turn down...

http://www.eizo.com/data/downloads/brochures/pdf/FlexScan_EV_1109.pdf amazing! Adjustable to Just 1% of Maximum Brightness. In a dimly-lit work environment, a monitor with low brightness settings will be more comfortable to use. Both models come with LED backlights that allow for adjusting...

ok thx.. so it wasn´t a problem with my graphics-card. but strange thing is that samsung claims S24A650 covers 92% sRGB... i think that´s wrong. which graphics card do you have?

hmm - do you have a problem with blue colors or not? my problem was that facebook looked violet and not blue...

here is a japanese review: (translated with microsofttranslator) http://www.microsofttranslator.com/bv.aspx?from=&to=en&a=http%3A%2F%2Fwww.the-hikaku.com%2Fdisplay%2FEIZO%2FEV2335W.html response time is not perfect (16ms black-to-white-to-black): translated text:

yes...it is. it looks less glossy on this pic: http://blog.tsukumo.co.jp/mt-static/FileUpload/pics/dosv/Imagerecord/201110/%E3%82%B5%E3%82%B9%E3%82%B1%E3%82%A7/ev2335-2.jpg maybe it only looks so glossy if you watch from a wide angle... microsoft translation: Surface is a nonglare but will...

yes! i like non-LG matte displays too... and i hate LG-hard-coating.

yes i use DVI. i tried another cable too - but bizarelly only with S24A650 and S24A450 i had the violet tone. i recently also tried the iiyama B2475hds (also DVI) and the blue was ok with it. very strange..

which graphics card do you have? i returned my S24A650D and S24A450BW because facebook blue had a light violet tone. i searched "blue" with google and got only violet pictures ;-) i think it has to do with my intel hd3000 card in combination with samsung SA(4)(6)50 montors...

i tested u2311hm und u2412m -> i returned both due to hard AG-coating my eyes don´t like that crystal sparkling on white backgrounds ... especially reading texts causes eye exhaustion.. i prefer lighter coatings...

@tokie do you have good blue colors? is "facebook blue" accurate or does it have a violet tone?

hehe - that´s globalisation ;-)

did you get it already? are you satisfied?

waiting eagerly... would be nice if someone could test it in combination with intel HD3000 graphics too...

does anybody use this monitor here? i know reviews of X2472HD (with bad response time) - but i think XB2472HD has better overdrive. in reviews of X2472HD there was only OD=on and OD=off. the new version XB2472HD has OD=off,1,2,3 (iiyama mentions it in manual). so i think they improved...

yes i use DVI. i reinstalled the driver... and even installed a newer version. light blue is ok...but some blue tones (like facebook) look violet... very strange. i deleted all ICC profiles and tried calibrating it with integrated windows 7 display calibration. nothing worked.. now i use my...

i bought it from a german online-shop. i have no calibrating tool... but no other monitor i use has this problem (only S24A450BW and S24A650D). it was not possible for me to get pure-blue colors (e.g. on www.facebook.com) with those displays. may be it´s a problem with my intel HD3000 graphic...

ok - i will send it back. it´s not possible (for me?) to get nice blue colors. Too bad, because apart from that it´s a very nice display.

yes there is a difference between normal, fast and faster e.g. in this trailing test (black/white): http://tft.vanity.dk/monitorTest_scale.html if i move the black square on grey background: with fastest i can see some white ghosting (shadow)...with normal there is more black ghosting...

i only have a very cheap smartphone - the pics look very bad - so it wouldn´t help you. i tried to make a video but my camera is so bad that blurring looks worse on video as in real.. i can say it´s much better than this: http://www.youtube.com/watch?v=VT6C6bp1oEM&feature=related this violet...

i bought this monitor now... it definitely has overdrive...i can choose between normal, fast, faster. response time is not as good as e.g. dell u2412m but it´s ok for me...i don´t realize it in practice (i´m not a gamer). i would say it´s even better than my old samsung 940b (with tn-panel)...

maybe it´s overdriven per default without extra settings...

here are some pix: http://www.itsvet.com/popup.php?pg=si&img=/img/obj/articles/000/000/005/136/01.jpg http://www.itsvet.com/popup.php?pg=si&img=/img/obj/articles/000/000/005/136/04.jpg http://www.itsvet.com/popup.php?pg=si&img=/img/obj/articles/000/000/005/136/03.jpg...

yes i also noticed that... but i do not think that a non-overdriven mva-panel can achieve 8ms response time. maybe some models only can turn it on/off instead of normal/faster/fastest or SA650 has enabled overdrive as standard.
