Mini-Review: Samsung 40KU6400 as a monitor

Got the UE40MU6472. It has grainy colors and shimmering whites the closer I look. What causes this? Is it a limitation of VA or the fault of the "semi glossy" finish? How do I get a monitor/tv with clean colors and whites? Am I the only one that notices these things?

I had exactly the same. The TV was good by not quite good enough and it defeated my numerous attempts to fiddle with cables and tweak settings.
In the end I sent it back and got a proper, but twice as expensive, monitor.

If your a programmer, and need the text to be crystal clear, or a FPS gamer that needs a decent response time then I'm sorry to you may find this TV lacking.:(

It's the anti glare coat. It's a bit too much when up close.
 
Set now calibrated as per specs earlier in this thread, and thus far delighted, got my PC, XBox One S and PS4 going through the TV and no isssues thus far. 4K looks fantastic.
 
Hi Guys could someone /some of you post a couple of screenshots of how you use the screens from a productivity point of view, please???

I assume some of you must actually work on them at some point? I mean with multiple browser windows open and or multiple text document windows available?

in either a side by side or overlapped/quarters layout etc.

Just wondering how usable it would be instead of a multiple monitor set-up considering I need 2 minimum, ideally 3 with only the center monitor being of real quality, just trying to weigh up the costs savings of buying a single TV live this for instance versus central monitor and lesser side monitors, both in reduced overall width and increased real estate with 4k as an added bonus. main use would be productivity rather than gaming and the only reason I would need decent central monitor is that I'm coming from a decent laptop screen and currently using an older laptop as a second screen and it sucks in comparison :/ costs of triple set up is prohibitive at the moment, but this might be viable if theres enough usable screen ?

what level of card would be required for this compared to driving triple monitor setup?

Thanks.. N.
 
On a slight tangent, I use a 27” 5K iMac for my work. I moved to it from a three monitor 1080p setup. I have to two 1080p monitors on either side of the iMac which I now rarely use as it’s quite amazing what you can get on a high res screen. I frequently have two remote Window desktops open along with Mail and Safari. Everything fits very nicely and it makes a real difference having everything one screen right in front of you. The only niggle I have is occasionally I can strain to read text but that’s rare and a moot point if you’re considering a 40” screen.

Regarding graphics card, the iMac has a 390m card fitted which has no problem with running a 5K screen and the two 1080p monitors.

Thanks, Bluecube, I appreciate the lateral thinking :)
 
My Xbox X is coming in November and I really need to sort out a new monitor or TV.

My shortlist is either

LG 43" 750V HDR10
Samsung 32" 4K Monitor (no HDR)

Think they are similar priced, and I am tempted to get the Samsung as I think 43" will be too big for a monitor. Especially when I'm sat doing work on it.
 
I went from a 32" 1440p @60htz monitor to a 34" 1440p @60htz ultrawide to a 40" Hisense HDR 4k tv @60htz. Once set up correctly the tv does a fabulous job imo and it'll happily do 1080p @100htz aswell. I've still kept all the monitors though. 40 inch is probably a tad to big in reality but I've got used to it and now I wouldn't change.

Stay away from LG and their RGBW structure. One of the biggest cons in the TV market, not even true 4K, more like 3K.

Samsung would definitely be the better choice, and as you say preferable for sitting in front of at a close-ish distance.
 
Pretty close to ordering a UE40MU6400

Currently running dual screen setup with IPS 24" (1920x1200) & 22" (1600x1080). Been wanting something bigger for a while. Use for mixture of web, work, media and games.

Don't want to go back to the poor colours and viewing angles of TN. A 34" g-sync IPS ultra-wide looks great but can't justify the silly price when I could get a decent 40" 4k TV instead for half the price. If monitor options look much better in a few years time can always buy something new and stick the TV on a wall somewhere.

Only running a Nvidia 1070 but am prepared to turn a few settings down or experiment with running ultra-wide resolution in letter box depending on the game.

Are there any major issues with PWM, ghosting, backlight bleed, text crispness that I should be aware of before ordering?
 
Jonathan, I'm viewing a 6400. There is pwm if you use an external camera(mobile) to film. It appears below backlight 9/10, I have brightness on -5 and contrast on 90 for general use. That's still pretty bright. I'm still experimenting with light lamps to brighten the room/desk space. Also with the settings on the tv from this topic and a youtube video mentioned in this topic.

I'm on a 1070 and not playing any recent AAA, so no idea on high, but older games, homeworld2 is big!

I am though seeing a slight viewing angle colour shift. As I slump, which prompts me to sit back up straight. The monitor for me is a bit low, so I have it up on some books till i decide to strip my other monitor off it's arm. Iv'e come from dual 2515's to through a 3415uw. I do software dev and a bit of other stuff. If I grid the screen into quarters it's like the old days of 4 19" monitors. I also have a x230 which is prone to pwm and I know I 'suffer' it. The x230 won't do the 4k screen, it will drive the UW though...

Do I prefer it to the UW... maybe. Still adjusting to it's dimensions. I think I'm honestly laying out my windows in the top 1500px area, the lower area, i.e. the bit not on an UW I'm putting ancillary console/test/reference materials, so not actively watching all the screen. I guess it's great to have I can push stuff away, but still have it. That said I also like single 'panel' focus, so code and console only feels pretty big, but very sharp and easy to view.

I've also pushed it back as far as I dare over the edge of my desk. To the point I'm not moving my head, just my eyes. I'm also a screen use glasses wearer, but have found I've not needed to reach for them quite as often as I did before. But the screen is now an extra 6" inches away...

Is it worth it? Prime 4k kicking back with a beer, yes... 8+hours a day developing code, not so sure, but I'm kind of saying yes, if I can tame the brightness. If not then when santa is done in january sales it might get paired with a console.

HTH.

Looks like the only TV's with better pwm are Sony but there 43"+ and cost more. Seen pwm mentioned as an issue for some of the more expensive 4k 40"+ monitors as well. Will have a look at one in a shop and make sure to mess around with the back-light setting, don't think i'm overly sensitive to flicker unless it's really bad.

I do like the idea of a screen that can have a useful second life when I move on to something else, a curved 34" ultra-wide seems very limited in it's uses.
