I came across one possibility to try, matte panel, got decent review in bright rooms and as an overall unit, but because it is last years model, i cannot easily it in local stores (determined by checking their online website stock).http://reviews.cnet.com/flat-panel-tvs/lg-infinia-47lw5600/4505-6482_7-34468431.html
This year's version doesn't have a matte screen but got decent reviews overall and for bright rooms.http://reviews.cnet.com/flat-panel-tvs/lg-47lm7600/4505-6482_7-35117974.html
I might try picking one up and testing out the glare issues. It seems available at local box stores.
If the glare is not as much an issue as i think it may be, i might reconsider a plasma instead.
