@Scataphagos the HPs do not have VESA compatibility, so moving the angle around maybe a bit of an issue too.
Please explain what do you mean here by frameless really ? Is it something good really or what ? I am doing all my trades from something like 24" 1920*1080 8 years old ASUS monitor and that's really it and I am happy, it's like 75HZ or so. Does it matter ?
Frameless is a slight misnomer, because even frameless (at least in the mass market) has a very small frame - just that it's comparatively much smaller. It's probably most important for multi-monitor setups - when a larger frame becomes a big pain.
