I want to find out want video card I have.. but I am having some issues. On the HP reference site it says there's an ATI Radeon HD 4200 with VGA and DVI installed in my model, but that cant be it because mine has DVI and HDMI. So I open device manager and checked under Display Adapters and it said ATI Radeon HD 5450, but according to their website (http://www.amd.com/en-us/products/graphics/desktop/5000/5450) it says it has a HDMI, VGA, and DVI and this website (http://graphics-cards.findthebest.com/l/64/ATI-Radeon-HD-5450) it states the max digital res. is 2560 x 1600 which that doesnt match up with what my computer's max res is which is 1280 x 1024. Can anyone please help find what video card model I have?
