I feel your pain, I was there 4 years ago. You don't mention resolution but I'll assume even with doing the native resolution of your TV, 1080P or 720P it was still blurry. DLP works for HTPC movies or gaming but when it comes to fine text on a browser it is not so good.
I don't know what your budget is but my advice for questions similar to yours is to point you to Vizio. The simple formula is take your budget and apply it to the closest matching TV price for a Vizio and your pretty much done. That TV will support the resolution you need, work great with HTPC, deliver stellar movies and gaming (including response times). The only thing to consider is if you want higher frequencies which only help in movies, Micro Dimming (Blacks are more blacker, cool if you want to pay for it) or extras like apps and wireless.
If on the other hand your looking for deep dives on tech specs and comparisons that is a different discussion all together.
So if you want the easy path go to Vizio.com, pick your TV, hop over to Amazon for the best deal, order and sit back and relax. You won't be disappointed and you won't have spent weeks researching a TV. Plus Amazon has the best return policies and service that I know of so even if there is an issue Amazon is there to help.
