nogahorovitchHello,
For home office use, for mild eyesight problem, I would like to know what monitors have these specs.
– Size 46″ to 55″
– Aspect ratio 16:9 or 16:10.
– No need for interactive/touch– Flicker-free, with no PWM at all.
Including no high frequency PWM, and no PWM that starts at low brightness level (less than 20%).
PCM2Hi nogahorovitch,
I’ll leave this open for others to chime in if they can, but I don’t personally cover or track monitors larger than ~42″, so that excludes Large Format Displays (LFD) which is really a category of its own. I am aware that BenQ models advertised as ‘flicker free‘ will be entirely DC dimming at all brightness settings. But I’m not sure if they actually have any current models within that size range, aside from interactive displays which will come at a hefty premium.
nogahorovitchThank you.
Regarding BenQ – are there any recommended models?
In addition, is there another brand in the field?
And does anyone know if these ones are flicker free?
PCM2As I said LFDs really aren’t my field so I can’t make any specific recommendations. Having looked at their range I’m not actually sure BenQ’s large displays actually are flicker-free – seems to only apply to their monitors and they don’t stretch to such sizes. The C5519Q does specifically say it is ‘flicker-free’ in the manual, but whether that’s true DC dimming isn’t possible to know based on that. EIZO generally uses hybrid dimming for monitors, so would usually employ PWM at low brightness levels.
It might be worth considering TVs instead. Again, not my area aside from a passive interest. I know for example the Sony X80K and X85K series are flicker-free and use DC dimming at all brightness levels. They include sizes within your range – 50″ (KD50X80K, KD50X85K) and 55″ (KD50X80K, KD55X85K).
nogahorovitchThank you very very much.
Do you know if the flicker free TÜV certificate permit PWM if it is high frequency (so can’t be sensed by naked eye), or only true DC dimming ?
Because many say they have TÜV certificate, but they for example LG OLED https://eyesafe.com/oled/
“OLED minimizes eye strain by eliminating flicker that can’t be detected by the naked eye and glare that disrupts your viewing experience.”
And OLED is not PWM free.Second, about using TVs.
I use it for home office use – reading texts, 14 hours a day. Sitting 1.5 meters from the monitor.
I have mild eyesight problem, and I want the monitor/TV to display large fonts, that are also thick and not only thin and long.For that I need to use resolution lower than the native resolution.
Are TVs function as good as monitors in their interpolation/smoothing smoothing algorithm ?
I don’t want it to soften the fonts.And in specs usually there is no data on PPI/ Supported Resolutions.
Edits:
About BenQ – Do you about the rm5501k / RM5502K / rp553K models ?
About Sony –
On RTINGS it is written “it does flicker at a very high frequency with the backlight set to ‘0’”So is it not true DC dimming ?
PCM2Refer to the article on viewing comfort as it addresses some of your questions regarding certification and also explains that what OLED models use is not the same as ‘traditional’ PWM. As I noted earlier, for monitors at least, when BenQ states ‘flicker free’ it means pure DC dimming. Not sure that extends to their LFDs .
The Sony TVs I was referring to are the “K” not “J” models. They use DC dimming across the brightness range, like I said. Interpolation is very variable on monitors. And some TVs are better at it than others as well. The Full HD resolution is pretty much always going to be supported. WQHD, not sure. You should run the screen at its native resolution and use scaling if you want things to be larger without upsetting clarity, not run the screen using interpolation. Which is always detrimental to clarity one way or the other. The exception would be if you often use applications that don’t use scaling or don’t scale ‘cleanly’, but most now do.
Edit: To reiterate, TVs and LFDs aren’t my area so I won’t be addressing further questions related to any additional models. I’ve been very generous with my time already.
nogahorovitchThank you very much for your help so far.
I apologize. I got a lost in trying to find the monitor for me.
I’ve been reading for days, and can’t find more information.
Your site was the best.If it is possible to have additional help and information for payment, I would be grateful.
Maybe privately- email, phone call, etc.PCM2I appreciate the thought, but it’s really not an area I can provide further advice on. LFDs are not reviewed by reliable sources that would provide data on backlight dimming behaviour and there is no way of knowing whether pure DC dimming is used at all brightness levels based on the information manufacturers provide.
nogahorovitchThank you again.
Maybe you can refer me to a site and/or a person where TVs are reviewed by reliable sources ?
PCM2RTINGS which you’re already aware of provide reliable testing of flicker and other performance attributes for TVs. They will say if a model is entirely flicker free at all brightness levels. As with the Sony X80K and X85K series I mentioned earlier.
nogahorovitchThank you.
I will try to find information on RTINGS.
My default is to compromise on the Sony, so to have some sort of solution for the next 1-2 years.
And then there will be more reliable information, and new models, so then I will find the “perfect” screen for my needs.But I would much prefer, if there is someone, that for payment, can search for reliable information, as much as available on 10-15 models that I currently gathered, and prepare a some sort of comparison/report.
Then by the elimination, I will converge, and see what models remain, and choose the least bad.PCM2As I mentioned previously, LFDs aren’t covered in this way so nobody will be able to do that for you. Especially as any information provided by manufacturers and even viewing comfort related certifications do not provide a definitive answer. On the TV side RTINGS has all the information you require. But you’ll see that only a minority are truly flicker-free and you’re unlikely to find something better than the afformentioned Sony models.
nogahorovitchI know that even the certifications do not provide a definitive answer. and approve high frequency PWM as flicker free.
Very frustrating. But that is what there is.I will dig more on the RTINGS site, and probably will go on the Sony models.
And again, I want to thank you tremendously, I’m so grateful.
Your highest quality information helped me so much,. A light in this lack of reliable information ocean.In addition, I start thinking about compromising on 42″ monitor.
What are the best true DC dimming at 42″?
PCM2I appreciate the kind words. For ~42″ options I know the Gigabyte AORUS FV43U provides DC dimming at all brightness levels and some people certainly enjoy it for general viewing comfort and productivity. The contrast is very strong, which gives an ‘inky’ look to text that can help text stand out a bit more. It has a BGR rather than RGB subpixel layout, like many such options, which means there will be fringing in some instances and it will be unsuitable in multi-display setups next to models with regular RGB subpixels (see our explanation of this in models like the FI27Q-X).
nogahorovitchThank you very much again.
nogahorovitchI decided to go on 42″-43″ options. Because the Sony’s have semi gloss screen finish.
I need matte screen finish..I looked at Gigabyte AORUS FV43U, and it also have semi gloss screen finish.
What more good options with true DC dimming at all brightness levels, with no high frequency PWM, that are matte ?
Preferred with ‘inky’ look.
PCM2Large panels like that are almost always glossy as they’re co-produced for TVs or produced on TV-focused production lines – where that’s pretty much the default screen surface of choice. And the few that do have a matte screen surface (for example the Dell P4317Q and Dell U4320Q) use PWM or aren’t known to definitely use DC dimming. Do you actually have experience with high refresh rate OLED screens? Because as noted the brightness dips are not the same thing as traditional PWM and they may not cause discomfort or other issues. And the upcoming ASUS PG42UQ and PG48UQ could be options – they will offer matte screen surfaces.
nogahorovitchMany thanks again.
I experienced the high refresh rate OLED‘s – LG 48″ c1, and Gigabyte AORUS FO48U, and unfortunately they weren’t good for my eyes.
About the ASUS PG42UQ and PG48UQ (it gives me hope), Do you know
1. If they use DC dimming ?
2. When will they be released?Regarding glossy surface- is there a way, at a customer level, to install some coating so to make it matte ?
PCM2I’m sorry to hear that. The ASUS models will very likely have the same brightness dips as other OLED models, I’m not sure if this can be avoided. It has been seen on all current OLED models I’m aware of based on LG WOLED panels (like the ones you’ve tested and the upcoming ASUS models), JOLED RGB OLED (like PA32DC) and Samsung QD-OLED (AW3423DW). The ASUS models should be releasing very soon, I believe August if all goes to plan.
You can actually install ‘matte screen protector film’ yourself, much as some people would do with a phone screen for example. So yes, that is certainly a possibility.
nogahorovitchThank you so much again.
I will install matte film, so I can not to rule out glossy model.
For ~42″, is there another option, in addition to Gigabyte AORUS FV43U, that is true DC dimming and no high frequency PWM?
