They'll be bringing both to CES next month, but don't expect pricing information until after.
Ultra high definition sets have thus far trended towards the incredibly large in terms of size. LG's newest sets break the mold a bit by offering you a ridiculous resolution in more reasonable sizes. The company will be bringing both a 55 inch and a 65 inch set to CES, which brings UHDTVs into the realm of possibility for small and average sized rooms, instead of just the ones that can accommodate an 84 inch monster.
The company seems to be focused on higher resolutions this year. They're also showing a 30 inch UHD computer monitor and a laptop display with a resolution of 2,560 x 1,700. If it's higher than high-def, you can bet LG is going to be bringing it this year.
