Despite the defective tv the 4k experience seemed alright on this low cost television, however the 1080p display seemed subpar compared to my current larger HD television. I also wanted to add that in 4k mode it looked pretty good hooked up to a computer monitor, but I didn't want to test my luck purchasing another for fear I may receive another defective TV. I went into this purchase knowing full well I might receive a defective item after reading numerous reviews where this was the case, however there were also many responses that were positive, so I decided to take a chance. If you do purchase this TV, check all the connections and test it out as much as you can to see if it has any defects. It wasn't until I had three separate devices and was switching between sources that the defect presented itself. Maybe you will have better luck than I with your purchase.
The screen real estate is.......oh boy........bloats my mind out of water. It's the first time in my life that i think enlarging window to fit screen is such a stupid idea.
The reason for me buying a bigger screen with more resolution is i want my head move more so i don't get a stiff neck sitting in front of computer for a longtime, without sacrificing pixel density - Mission accomplished!
Be very careful to check if your computer is compatible with 4K resolution. I run GTX 750M SLI in my laptop and mouse is very smooth with no lag. But i tried it on my AMD A10-6700 with Radeon HD 8670D desktop from ASUS, even they say the set up is well above 4k 30Hz in AMD website, the cheap manufacture somehow shaved some parts out of the original GPU or HDMI that i cannot get more than 1080 60Hz. Some other people see lags in 4K i think its probably because it eats up too much GPU juices.
I tried 4k streaming in youtube and it's just so stunning that i keep shouting that irrigates my girlfriend a bit until she come over to the screen. We spend hours watching scenery videos in 4k just for fun without even at all bored! i am sure i will be bored in 10 min in HD because there are only 1/4 information in a frame compared to 4k.
If you are sure your computer graphics runs 4k 30Hz, this is a screen that will bring you to the real 21st century - of course, without breaking your bank
I have now found myself avoiding using the PC that this monitor/4k TV is hooked up to, because the colors are poor. If I am making an Amazon purchase where "looks" matter, I use a different PC to make my purchase. If I am buying books, or simply surfing the web, then I will use the PC that this 4k TV is hooked up to, because the resolution allows me to have multiple screens open with readable text.
I am somewhat torn. I purchased a video card that was supposed to work with this TV, but I am not sure if the problem is my needing a more expensive video card, or it the fault simply lies in the monitor/TV. I recommend doing your homework and research, and saving your receipt. More importantly, verify the return policy in advance, because you may find your self unhappy with the purchase, and some sellers charge a restocking fee.
I have been attempting to connect my Firepro W7000 workstation graphics card with 4 displayport outputs to my Seiki SE39U&04-1 39" 4K TV to use as a monitor. Various adaptors to convert the displayport to hdmi were tried until I finally found one that worked.
Accel B086B-006B-2,UltraAV DisplayPort 1.2 to HDMI Active Adapter. This is the one to get. It connected at 4k @ 30Hz automatically, AND transmitted sound also.
StarTech DP2HD4KS. This is also an active adaptor. The first one only did 1080p but looked damaged out of the packaging, the second I received did 4k @ 30Hz, BUT no sound.
Cable Matters Gold-plated DisplayPort to HDMI Male to Female Adapter - 4K Resolution ready. This I presume is a passive adapter. My graphics card is capable of outputting via passive and active adapters simultaneously, but I only got 1080p with this. I really doubt you can get 4K with any passive adapter, since I had also tried one from Monoprice that did not work also.
I adjusting settings based on other reviewers advice and find it great as a monitor. I have no issues with the 30Hz refresh rate, but use it mainly for spreadsheets and 3D cad work.
The settings that I've found best so far are:
Picture Mode: User
Color Temp: warm
The monitor works well for writing code, and browsing the web. I have found that it is a bit slow for use in Lightroom, but not to the extent of being unusable. I feel that's it's pretty good considering the price, and considering that an actual 4k monitor of this size would cost three times as much.
