Can you give me the dimensions?
It is 551x344mm (21.7 x 13.5 inch) visible.
The 19 inch screens were like 366mm (14.4 inch) vertical (visible picture). So that is about 1 inch less.
Guess the Happ is a 16:9 screen, those are 324mm (12.8 inch) tall.
24.8 arcade monitor is about 23.00 wide x 20.63 tall.
That is the worst ever application of Pythagoras law

!
A 24.8 inch arcade monitor with 24 inch visible image means a 488x366 mm picture (19.2 x 14.4 inch). Exact the same a 19 inch monitors mount vertical.
The W2753V-PF is 16:9 as well, so 336 mm tall (13.2 inch), and it is TN, so not the best viewing angles.
It is also not the fastest (problem of all >23 inch TN displays), with a 22ms lag.
Here you can see the measurements of its European cousin:
http://www.digitalversus.com/duels.php?ty=6&ma1=35&mo1=464&p1=4589&ma2=322&ph=12So it's fairly close to an arcade monitor and I'll figure out if I want it vertical or horizontal.
It's TN, so vertical is no option.
