I have been using this as a 4K monitor on my Linux laptop, I keep getting this uncanny feeling that the panel uses RGBW (not true HD), That is because the images are not as crisp and sharp as I would like.

I did a few pixel level tests using Gimp creating 1-pixel R, G, B, W checker-board patterns and find that the white checkerboard patterns is the sharpest, while the
red, blue and green patterns are very blurry at 1:1 pixel level.

When I look closely at the panel (grey pattern), I see that the green pixels seem to be alternating, but I could not see a white pixel, only RGB.

Without a magnifying class, it is hard to draw any conclusions, currently I am inclined towards thinking that this is not a true 4K but a RGBW (2880 x 2160) monitor.

Need more experts to chip in.

Note: if you use it to watch netflix, this should not concern you. It only concerns folks who want to use this as a 4K monitor (for doing work).
Canít really complain at this price point isnít? 😂

No complaints about the price. Only gripe is with the dishonest marketing of a 3K RGBW TV (*) as 4K. I wlll have to look for another true 4K monitor, and move this 50" AOC to my living room as a movie display. Lesson learnt.

Analogy: pay peanuts get a cheap 4-speed bicycle, only to find out that it is really a 3-speed.

(*): search youtube for RGBW vs RGB TV to see the difference. LG is infamous for marketing RGBW 3K TV's as UHD 4K.

Got $699 Akira 55" Curve True RGB 4K Tv

I could not longer stand the graininess of my pseudo 4K AOC 50".

Went to Audio house last night to look at each panel at the pixel level, found that the cheaper "4K" screens are all RGBW, made by:

Panasonic, Philips, Toshiba, LG (notorious).

There are a couple of True RGB 4K from samsung, panasonic, sony, 43" to 49", around $999 to $1.3k

There is one exception, Hi Sense 55" 4K is true 4K, I borrowed a chair to examine the panel (located on the upper racks).

There were a couple of Samsung display set TV (55" curve) at $1400, with 12-mth warranty. But I did not get those as 1) over my budget of ~500 sgd, 2) they probably have little remaining of their LED panel life (switched on for 10 hours a day for at least one year as a display set).

This morning, I went to Vivo City Best Denki, and looked at a few TVs, found the same situation. There is one very good deal

$1899 Panasonic 65" 4K TV model TH65EX640S

In the end, I went to Big Box Jurong and scrutinized the Akira 55" 4K curve screen. It is true 4K, and comes with 3 year warranty. Took it home for $699 (including tax). This Akira is a dumb TV, with neither Android nor wifi. This is good for me, as I intend to use this as a compute monitor.

The AOC 50" was very distracting, tempting me with netflix every now and then. It has since been shifted to the living room.

I am typing this post using the Akira 55" Curved true 4K screen.

No more graininess, and fantastic color! It is equivalent to getting four 1920x1080 screens stacked 2x2.

Well, apparently according to another forum which did took close-up photos of the screen stated that it is true RGB aka a real 4K panel...

Essentially, page 20 to 21 were devoted to the topic of RGB or RGBW on that forum/discussion...

@lovehikki Thanks for the very informative links!

I can confirm 100% that my $568 (ntuc fairprice) AOC 50" UHD has a RGBW panel. I have ran exactly the same test patterns, vertical lines:

vertical pure color X 1-pixel wide line

x = red, white, green, blue

The earlier AOC models might have shipped with RGB panel, but not mine.


I have also confirmed that the sub $800 4K panels as of 2018.04 are 99% RGBW pseudo 4K. (With the Akira 55" being one notable exception)

I put my 55" monitor on a dining table (long edge), and I sit on the other edge. it is like having 4 full HD monitors stacked 2x2.
