Thanks for the info. I went ahead and clicked through and ordered the Dell U2415 from Amazon.

Your support is appreciated. 🙂 Hopefully the monitor works well for you.

What do you make of this ?

The cause ?

[PCM2]

That’s an issue reported under certain circumstances for all models using that panel, including the Samsung S32D850T and AOC Q3277PQU as well. So it’s something to do with the panel itself rather than the monitor. I am unsure of the exact cause, but it isn’t something inherent to VA technology more broadly and there’s no reason to think future panels will suffer from it.

Are 4k/2k panels VA with good responses (better than avg IPS), and high ppi (150+ or 200+) panels coming this year? How are their color quality(esp banding) and black levels compared to IPS? I’d really like an IPS in future but that seems to be at least 3 years away at sub 1000$ prices.

Also do you know of any 15/17in monitor (IPS/VA) with good color quality, brightness and high ppi (at least FHD)?

[PCM2]

There are no VA panels that I know of under development with a higher pixel density than 139.87 PPI and even then only one single panel is known to support this. Refer to our review of the AOC U3277PWQU, a European model. Our reviews quite clearly show that ‘banding’ isn’t an inherent issue with the technology. It’s actually more that the strong contrast and lack of ‘IPS glow’ helps reveal more imperfections in source content than on other LCD panel types. Poor gamma handling exacerbates this, however. And there is variability in perceived gamma on VA models as explained in detail in our reviews and indeed in this thread.

There is little interest (from me, manufacturers and users in general) for 15/17″ models of any resolution, I’m afraid. So that isn’t something I’ve researched recently. I have also removed your mention of a retailer at the end there – be sure to familiarise yourself with this post.

Thanks…

The reason I was interested in banding because I’ve started to notice it more on my IPS monitor. I get banding in stuff like the speedtest.net background and Awakening NewZealand sky. I can’t recall more examples currently. Not sure if this is usual for an IPS panel.

It would be nice to have a secondary monitor for reading and old games without eye strain. Also I wanted to recreate my old CRT a bit. I play some 10-12yr old games with cartoon graphics which looked fine on the CRT(65ppi) but lines look a bit jagged no matter windowed or FS on my 90ppi screen. I was wondering if this is due to the PPI of the screen and the gap between pixels on LCD, or something to do with shape of pixels.

[PCM2]

I’m not sure about Awakening New Zealand as I haven’t watched that recently, but the Speedtest.net gradient is simply not a smooth gradient. It is therefore an issue with the source, not the monitor. I can confirm that there is some banding on a range of monitors, including none other than the U3277PWQU (10-bit) on that page and other similar gradients (in Steam etc.)

When you say those older games looked ‘fine’ on the CRT, all it likely is is that the sharpness of the LCD is superior. The CRT simply gives a softer look to the image and hence blurs those jagged lines. As with banded source material, it’s not a defect if a monitor is correctly displaying the source material.

I am looking at LC24F390FHWXXL and S24D390HL , but the later is now out of stock.
the former is available on sale soon and cashback. its also have freesync. its va panel. is it good?

[PCM2]

The preferred designation is simply C24F390F(H). I haven’t tested that model as Samsung don’t have a sample. From user feedback so far it sounds fairly similar to the C27F591FD we’ve reviewed in detail, but offers an inferior colour gamut (less vibrant colours) and of course is a different screen size.

[karandex]

So this va panel is inferior to ips? i saw someone returning 27inch version back. I think this monitor is best bank for the buck, but how much i am loosing on not having IPS

[PCM2]

Instead of asking highly subjective and possibly rhetorical questions, make use of some of the resources here. The first post of mine on this thread, the Samsung review I’ve linked to. They offer the most detailed comparisons between how the two technologies are to use that you’ll find on the internet.

Review of the EW2775ZH on XS Reviews.

Good color accuracy, but disappointing color uniformity !

Is this typical for VA ? Or does this simply show a bad color filter and/or back-light implementation ?

[PCM2]

I’m sure I’ve explained this before, but uniformity varies between individual units. In fact yes, it’s something I point out in every single review. 😉 Good to hear about the strong colour accuracy, although as mentioned in my first post here and in reviews you can’t just rely on what a colorimeter is telling you about the centre of the screen. There are perceived shifts on VA models that aren’t accounted for by that and they are also important to consider. Shame they only used a Spyder4ELITE to measure contrast – it’s likely around 3000:1 as claimed.

[Umbral]

Thank you PCM2, so basically even if it had perfect color uniformity slightly moving of the head or the viewing distance on VA would alter the actual perception.

Still interested to learn why does this color uniformity difference occurs on IPS for example, is it the color filter or the edge light that usually makes the color uniformity better or worse ?

[PCM2]

It is caused by imperfections in the ‘sandwhiching together’ of the panel usually. Once everything is packaged up into the monitor, slight pressure or even temperature differences can affect uniformity. Some backlight designs and panels are more prone to this than others and this is a key reason why doing away with the backlight will be a great benefit to consumers. 😉

My final choice have come down to
S2415H and C24F390F , has dell unit have become too old?
Usage is gaming and browsing internet.

[PCM2]

I’m not sure what you mean by ‘become too old’. It hasn’t been replaced by anything comparable in the European market. The S2415H still has a lot to offer with its glossy screen and AH-IPS panel. The responsiveness is decent enough for a 60Hz monitor too, a bit stronger than on the C24F390F in that respect. But it depends how much you value contrast over having a glossy screen and consistent colours.

[karandex]

I am worried about ghosting. That is the only thing have me against going for ips

[PCM2]

I don’t understand what you mean. As clearly explained in this thread and the relevant reviews, the VA models are worse in that respect. Modern IPS models don’t have ‘ghosting’ issues as the response times are generally about as good as they need to be if not just a little slower than required for optimal 60Hz performance. Certainly the case with the S2415H.
