I picked this up and it's nice. However I want it as a monitor and it's too big. I should have waited for the 42 to come down. Maybe that will convince someone else to not think it can be a good monitor. It's your whole desk.

Okay, so this or one of the Hisense U6 or U7 TVs. The 55" U6 will be sub $500 and the U7 will be $550 for the holidays. I under this LG is oled and the others are not. I just want a PC monitor.

Does anyone know if the 42" C5 LG will go back down to $700 for the season? Or an oled that is similar level from other makers.

lol get a bigger desk? jk, I had to install a keyboard pullout tray under the desk just so that my 42" would be from a comfortable distance.

Also a monitor mount so that I can push the monitor back closer to the wall.

Yes, as someone who has had a 42" C2 for a few years now I can't imagine using a 48". My only complaint with the 42" is that I'd like a second monitor but just no feasible place to put it.

I did the same, and same. Have a big desk and even then I looked like a cat following a laser pointer as I dragged my mouse across the screen

This is a smoking deal if you like me have been looking for a decent 50ish inch TV due to size constraints.

Been using a 48" CX OLED as my monitor for 5 years and love it. It all depends on what you want and the room you have.

Killer deal for this size, specifically because it's exclusive to best buy for the B-Series

Bought one for a family room TV that needed to be no larger than 50" to fit the space we intend for it

Anyone know of a way to vertically dual mount this? I have a 48" C2 for both my bedroom TV and gaming monitor. I have 3 PCs connected to it, but I can only use 1 PC at a time. I'd love to use my gaming or Linux PC + workstation at the same time.

Just mount the brackets sideways. Instead of VESA 300 x 200, it'd be 200 x 300

They have adjustable holes on wall mounts and such to accommodate nearly any VESA configuration within a given range.

This or the Hisense U7 for similar price. Judging by rting reviews , B5 brightness is dim, will that be big issue?
edit : seems like 2 weeks ago they were $20 cheaper , gonna wait for better price

Yeah that the only "drawback" in my particular situation, since it would sit atop of a 22.5" wide drawer.

Found a vesa compatible center stand for $22 bucks that will hopefully get low enough to fit within the 31.5" height restraint I have.
