AFAIK G2220 HD and E2200 HD has same screen panel. Only the bezel is different. So PQ wud be same, but E2200 HD has an additional HDMI port and has a headphone out. Get that is u have a PS3. Both have DVI.
dont know bout E2220 HD. Probably a new model.
I wud, get hte G2220 HD for 8k. gr8 vfm.
PQ wise, its better than sammy ss33sw. also 2233 doesnt come with dvi cable bundled.
