Looking for a good 40"+ 4K display "4:4:4 is a must"

post #1 of 10
Thread Starter 
I currently have a Crossover 434K and while it's excellent when watching videos, movies, playing games, there is a few flaws preventing me from continuing to use it as my desktop monitor.

The first issue is that it has a semi transparent film strip around the edges and blurs out UI elements if you're not directly facing them head on... The strip does not bother me on the bottom or top as most UI elements are placed on the side "and Windows UI elements are above the strip anyway"

The second issue is flickering now and then, yes this is a Korean A or B grade panel and actually this isn't even a major issue anyway...

Another issue is if you tap the power cord or even bump the input "my speaker is right next to the input and monitor" it will cause blurring of the screen or outright turn itself off which you have to unplug/re-connect the input and also even reboot in some cases + going into your video cards control panel and re-selecting GPU for scaling...

I also got a panel that has a slight led bleed/glow on the side but it's pretty small and not noticeable unless viewing bright content, I also noticed when viewing bright content that a "ocean wave" pattern was at the top of the screen and even a "4:3" square.. noticeable under white or most light content. You can view the photo for reference + the small back bleeding.."I'm okay with it as it does not interfere with any of my applications"

So yea.. that's my experience with the 434K not great, had MUCH better luck with the 404K until my cat actually poked his claws in the panel itself..


So, I'm in the market for a 40-43"+ display, TVs are fine as long as it supports 4:4:4 "IPS, VA/MVA is also fine" at 4K/60hz.

I'm currently looking at Sony's XBR43X830C which can do 4K/60hz and 4:4:4, it's also has a matte coating from what I can tell.

I have been looking into this market as well. I have found the AMH A399U. Many ppl are saying it's an upgraded version of the 404k? I dunno but from what I've read ppl suggest it's slightly different.
AMH A399U UHD 39.5" 3840X2160 16:9 4K LED Monitor 60Hz DP1.2 HDMI2.0
The description on ebay doesn't show 4:4:4 Chroma support but in the video review the seller links and in other forums I've searched it does support this. But FYI many people are saying that 4:4:4 4k 60hz has trouble on any port except for the DP port, so don't plan on using any port on this monitor except for DP. That might be a universal rule though, I apologize if I'm newb on this matter.

It seems all the name-brand 40s and 43 monitors that can do 4:4;4 have priced themselves out of reach for many of us.

I was actually going to recommend the Sony 43 as your first choice...mostly because, having used 4Ks at 39 inches (Seiki 39UY04) and 43 inches (Seiki SE43UGT), I have come to love the extra glass of a 43. At 106 ppi, it's not too coarse at all.

Other good choices, with today's prices as shipped to the USA, in ascending order of price:

$550 Yamakasi O40USUT. Check out the glowing reviews on U.S. Amazon.
$650 AMH A409U, Version 2. Just introduced last month.

Also, several Samsung 40-inch TVs introduced in 2015 will support 4:4:4 AND low lag after you change its settings. Two are affordable:

$650 Samsung UN40JU6500 (and maybe the 6400)
$800 Samsung UN40JU6700, a curved 40-inch. You can easily find one used for less than $600.

I just picked up the sony XBR43X830C over the weekend 0 issues so far. Pretty sure i may not be getting 4:4:4 red text looks a little off, but i am running amd gpus using the club 3d dp to hdmi 2.0 adapter. Everything is running at 60hz and looks great.

I sit about 3 feet away from the tv 0 scaling which i find may be a tad too large.
overall i am pretty happy with it will be keeping my 28" monoprice 4k as a secondary in portrait.

Let me know if you have any questions i may be able to answer

if you do get the tv make sure to enalbe the enhanced format options.

Try running just HDMI as you're adapting and I've heard issues with adapting when it comes to 4:4:4.. Let me know if that works, but only if your GPU has a HDMI 2.0 port.

Nice recommendations, and the curved 40" looks pretty sweet, wasn't able to find it for $600, $750 was the lowest I could find it.

I'm looking at this handy table: http://www.rtings.com/tv/reviews/by-usage/pc-monitor/best?uxtv=f055 and there seem to be quite a few monitors that will do 60hz @4k with 4:4:4 at 40/45 inches.

The Sony X830C 43" can do 4K @ 60hz 4:4:4 AND 1080p at 120hz. Unfortunately it looks like the contrast is not that great. Might be a good choice if you don't watch many movies. The X850C has a better contrast rating but the smallest is 55".

The Samsung JU7100 is great, and can sometimes be found for around $800 on sale so keep an eye out. The lower end models fared well in rtings reviews as well, like the aforementioned JU6500 and JU6700.

I've been out of touch with monitors since I got my Shimian but now I've been looking for an upgrade. I can't find locally (Romania) any of the Samsung / Sony models mentioned in this thread so this is my question :

Is there a korean monitor at 39-43" 4k IPS/VA that does 1080@120hz and 4:4:4 ?
