Below is a message I sent to a SAGE-AU list last year about monitor 
resolutions.  Ignoring the issue of manufacturing high resolution screens 
without too many dead pixels it seems that 20" is the maximum size for a high-
DPI monitor with today's technology.

According to Wikipedia dual-link DVI is only capable of up to 2560*1600, so it 
won't drive anything much better than the monitors we have been discussing.  
This might be a contributing factor to a lack of higher resolution monitors.

http://en.wikipedia.org/wiki/Display_port#Advantages_over_DVI.2C_VGA_and_LVDS

Display Port can do "17.28 Gbit/s of effective video bandwidth, enough for four 
simultaneous 1080p60 displays (CEA-861 timings) or 2,560 × 1,600 × 30 bit @120 
Hz (CVT-R timings)".

Four simultaneous 1080p60 displays is less bandwidth than a single 27" display 
with "retina" quality DPI.

There is apparently work in progress on TVs that have 4* the resolution of 
FullHD, so we will probably see monitors with 3840*2160 resolution soon enough 
which will use the full bandwidth of Display Port.  Such a monitor with 
"retina" DPI would be 20".

We need new cabling technology to have a "retina" DPI on a monitor larger than 
20".
