Your immediate issues are scan rate(resolution) and connectivity. If you can hook it up w/o special needs and use the default native supported resolution it could be easy. Otherwise, anything else needs attention and here is when many users start to delve into whatever works or can work. It may not be the best result but it works. You do need a capable video card with varying resolutions and connects. The monitor or TV is the other half and usually it doesn't flex, so the computer side usually needs to adapt or become the changing item here. Because, of all the varying products and cables, etc., it becomes finding this or that and hope for the best. That doesn't always mean the cheapest either, so consider what you're getting into and understand any return policy of brought items. Understand what works in one situation may not in another. I find this a problematic PITA area to deal in as explained above.
Since, you already have the video card and PC, find the specs in order to match as best as possible to any future TV/monitor purchase. The more ports and any setup feature the more likely its desirable. Be ready to review any manuals and listen intently to the salespeople. if they can't or seem unsure, move on. Try another store or vendor and look for possible arrangement for that vendor/store to actually setup the items, some do that now.
I am looking for a new screen for my desktop. I noticed that my dad managed to hook up his desktop to a 60 inch TV. At the same time, I was looking for a monitor and they were a little more expensive than the tv's and at a smaller size. What are the pros and cons of each? I just bought an XFX ATI Radeon HD 5770 graphics card.
