-Do you want 4:3 or WS?
-Response time is pretty useless information
-Input lag and moving-image artefacts are much more important, and never told in specs.
19 inch non wide screen is not 4:3 either, it is 5:4
19 inch TN panels should not be mount vertical.
The best LCD for vertical classic use is the HP LP 2065 or the Dell 2007FP (non-W model).
These are true 4:3, IPS (wide viewing angle) screens with low input lag and good game response.
