Looking for a gaming TV for + or - 500

So I love my 40 inch Panasonic plasma TV set BUT it has an issue with cutting off the edges of my screen when I hook it to my computer with an HDMI cable and NO hookup for a video cable to go to my PC. There is SUPPOSED to be a video setting that changes this but I don't think it exists. I've searched. Its now 15 years old so time to replace.

I'm looking for a gaming TV with a budget around 500 dollars. I will be hooking this to my gaming PC. Glare will sometimes be an issue. So what are my options? THX in advance.
