hantarex polo2 and polo star problems!!!

[mukuro]

hi!
I bought two brand new 25" arcade monitors from hantarex (one "polo2" 15Kz/25kz and one is "polo star" 15Kz/25Kz/31Kz" auroswitching). I cannot obtain a decent immage quality in both monitor
The polo2 one have a sharp image and very very good clours on screen but have a strange problem with screen horsontal proportion (in dot cross match I can see larger suares on the sides of the screen)

The polo star wich support 15Kz 25Kz and 31Kz have a strange performance in 15Kz: the sprites re too detailed and so "pixelous"

Anyone have used this monitor? Any advices?

Thanks so much in advance!

Sorry I cant give you an answer as I dont own these monitors, but at least this will bump your post to the top. Can I ask you how much they cost (each) as I'm thinking of getting one of them.

...Thanks...
