First of all, I no longer consider Vizeo an off brand. They are well established and sell many, many TVs.
There was a thread here recently asking why some TVs work well as a monitor and some don't. There were links in it which explained something (being vague because I don't remember well enough to quote). Bottom line is that only a few, probably top of line TVs make good monitors. You really need to find reviews of the model you are looking at and see if others have used it successfully as a monitor. I have a 23" Vizeo which makes a great monitor but that doesn't mean the model you are looking at would also.
