Nice debates. This is more or less growing into an expert panel and its sure covering fps peeping rather than pixel peeping, well, it is part of that of, so I figured I would throw in some interesting info.
4K resolution is very interesting and when it comes to normal content like net surfing, viewing photos, movie's etc the upper midrange class Geforce cards will handle that. But it is as many of you state very different running games in 4K. I did mention a while back that I am considering Samsung S27A850D as my photo editing monitor, well.... Samsung is releasing a 4K monitor ($873,- in my case) that is looking very interesting.
Samsung U28D590D (4K)
- 28" 3840 x 2160 p
- 1 billion colours = 10 bit (8+2 FRC)
- TFT active matris (TN) LED
- Viewing angles: Horizontal: 170 degree. Vertical: 160 degree .. that is PLS/IPS perspectives.
- Response time: 1 ms (GTG)
- Brightness: 370 cd/m^2
- Contrast ratio: 1000:1
- Refresh rate: 60 Hz
- Price: $873,-
Samsung S27A850D (2K)
- 27" 2560 x 1440 p
- 16 million colours = 8 bit
- PLS panel
- Viewing angles: Horizontal: 178 degree. Vertical 178 degree.
- Response time: 5 ms (GTG)
- Brightness: 300 cd/m^2
- Contrast ratio; 1000:1
- Refresh rate: 60 Hz
- Price: $690,-
My point is. Looking at the data (yes yes, I know that this is not everything one study) the 4K monitor looks damned good. Its brighter, have more colours, its larger, faster response time and it is 4K resolution than the PLS.
I play in 60Hz and I've always played in 60Hz. FPS, dunno, 40-50 on a okay card and I am okay with that. Not saying it is excellent, I am saying it is okay. Photos are always 1 fps, movies is always 24 (23.9**) fps and with correct tuned panel, the colours will almost always be within acceptable levels.
ASUS claim that this TN panel is a new type of TN panel and that the colour representation and viewing angles are close to IPS/PLS... well, look at the spec of the Samsung, this too is close to their PLS panel. So what if and that is a big IF, the TN panel IS the Samsung panel being released in the PG278Q - they can actually produce the panel with same technology but cut the size and use different electronics to run it, it happens all the time in this industry.
Ofc, the Samsung is not a G-Sync monitor and I want a G-Sync monitor for gaming but I also want a 4K monitor so that I can watch movies in that resolution and work with photo editing and CGI. Meaning I might need to do a combo here. I use two monitors now and will probably continue with that or in fact, keep my Samsung Syncmaster 931BF as a display for chats, music library AND Nintendo NES/SNES gaming monitor etc and then use the Samsung U28D590D as my image monitor and the ASUS PG278Q as my work and game monitor
Yeah... I like that idea.
