Okay, so you are looking more for a quality media monitor to fit your needs (light gaming, media viewing, general productivity). I stuck to the 27" size, as anything bigger is going to be way off your $300 price point, and tried to get you the best features I could find for what you are going to be using the monitor for. I've listed them in order of price (lowest to highest).
Acer G276HLbd - A good all around monitor. though it lacks an HMDI port. We have about 9-12 of these in multiple roles at the place I work and they are generally well liked.
ViewSonic VX2770Smhd - You mentioned this monitor earlier and it is a good choice for an IPS monitor. I've never used or seen the monitor in use personally, but I can't really find all that many negative notes about it that are consistent (no major problems that everyone reports). If you buy from Newegg before 4/8/13 you can use a promo code to get an extra 10% off which makes it close to the lowest price for a new unit from Amazon.
Acer S275HL - This is another good monitor from Acer. We have two at work and they are very nice. The only real complaint is that while it has a slim bezel there is a slight non-physical bezel around the perimeter (black boxing). One of the users at work finds this annoying, as he wants his display going right to the edge of the physical bezel. Also, there are no DVI ports on this monitor but rather 2 HDMI ports and 1 D-Sub port.
Dell S2740L - This is right at the upper limit of your stated budget and normally I wouldn't recommend anything from Dell, but their monitors are the one exception (3-year warranty is great). Normally this monitor is between $320 and $350, but I found it on Amazon for $300 w/free shipping. This is an excellent monitor and I have seen a fair number of them in use personally. A very clear picture with great color, the only real complaint I have ever heard or seen about this monitor is the fact that it has a rather glossy screen; almost mirror like when not in use and in use depending upon how you have room lighting set. However, if you set the monitor up with room lighting set properly you should not have any real issue with reflections.
Those are my current recommendations for you. If you want any more help, advice, recommendations, etc. just leave a note and I'll see what I can do.
