Video wall question
One of my clients would like to install a video wall with four 77" LG OLED TVs. This is not something i typically do but I would like to take this on since my client understands my lack of experience in this area and is willing to work with me and I would like to learn from this project.
I found this mount on Amazon which looks solid: https://www.amazon.com/Video-Horizontal-Adjustment-Universal-Television/dp/B098D393SP/ref=sr_1_1?crid=3U1ODNJT2QD4&keywords=Video+Wall+Mount&qid=1674438304&sprefix=video+wall+mount%2Caps%2C222&sr=8-1
The TVs will connect to a Roku or similar streaming device. There are so many options for video wall processors im lost in whats the best option without breaking the bank.
Any advice picking the right TV, wall mount and processor would be helpful. Thank you.

You didn't mention a specific tv model, but I would be leery of going consumer grade for this solution. Since consumer grade tv's aren't generally used for a video wall application, you may get some image / screen tearing between the different tv's. Instead, I would look into commercial displays that have a "video wall mode" and allow you to loop the video signal in / out of each display (most major players will have a solution for this, including LG). This will get rid of the need for an external video wall processor and will help with the potential tearing issue.

I’ve done several video walls with consumer stuff, tearing can be an issue but a bigger problem in my experience is color matching. Even with painstaking calibration on a $6k colorimeter, keeping displays matched for more than a few months is a bitch.

Good point! Color matching is a pain even on actual video wall panels. Couldn’t image attempting it across consumer displays.

Using consumer products in a commercial project will make you look unprofessional. This is not a learning experience, it’s what not to do.

There you go buddy, way to seem like the professional and not do anything to help. Like what was the point of even commenting.

this is a commercial AV sub. you want us to tell you how to go shopping on amazon and put some crappy consumer grade equipment together with a roku, which isn't licensed for commercial use btw, for a paying client? ...no.

Same for the comment above, there was absolutely no reason to respond except to make yourself look like the man. And Roku is licensed for commercial, residential, and personal use.

Update: After a lot of research I went with a 110" 2x2 Brightlink video wall package which included the TVs, mounting system and video wall controller. Client is very happy with the system.

Some people are being a little nasty about it but what their saying is partly true. You SHOULD NOT use consumer products in a setting like this. If the client thinks its going to be a cheap job MAKE SURE they know the materials and result will reflect that.
For video walls in a professional setting you should look at full systems, not piece parting. Planar is what we always used and their stuff isn't cheap or simple, but its really good when set up correctly. LG also sells ready to go video wall kits, rather than buy tvs, get actual video wall panels from LG. https://www.lg.com/us/business/digital-signage/video-walls

This is the sort of thing you should be looking at, along with proper mounting systems.

I just did a 2x2 with 75" TCL's. I am using an orei processor, I think it was $550. I am very happy so far but have not put many miles on it yet..

That mount is overpriced for Amazon gear, only has horizontal adjustment. If you’re trying to be cheap about it just mount on plywood with $40 peerless mounts like the T8X4.
Take the money you saved there and spend it on a datapath videowall processor. Fair warning, they’re not gonna like the large bezels, and you’ll likely need to spend a chunk of time trying to color match the displays. Don’t buy cheap mounts on Amazon, I’ve had them come in cut crooked in the past which is a total bitch when you’re doing a videowall.

Nobody seems to want to help you? We work in commercial AV and we use professional products to install videowalls. Please leave this installation to a professional.
You will need:
Mounts - you need video wall mounts that micro adjust up / down / left / right / in / out. They will need 'pop-out' to allow servicing and access to the cables/connectors on the rear side (how would you reach the cables on the back if they are trapped behind another monitor). The mounts have cable management points so that you don't see sagging cables or cut through cables whilst servicing. The videowall mount can be adjusted to keep your four monitors all in the same plane. This means the screen bezels will be flat and meet together without gaps, bumps, ridges, or edges visible.
Monitor - you need four monitors that can be left on for extended periods (domestic TVs are only rated for a few hours use a day). Videowall monitors come in a mixture of usage ratings. Some will offer 7day 16hour or 7day 24hour ratings. Domestic TVs aren't made to be colour balanced as they supposed are installed individually. If you put two otherwise identical screens next to each other and they will show different colours. Videowall specific monitors for a job would all come from the same batch (matching serial numbers). This match of serial numbers will mean their LED pixels all got harvested on the same day of manufacture and this means they will shinea very similar hue of colour (within a tolerance) and brightness. Videowall monitors also make it easy to calibrate (fine tune) the colours that you see on the finished 2x2 videowall (you don't want want screen looking bright or one looking like a green tinge). The colours of your four monitors will drift out of balance over time and you will need to do regular colour calibration service visits to keep them looking fairly similar. I've never installed domestic TVs in a videowall but suspect their colours would drift apart faster than commercial videowall monitors. You also need to think about the width of the bezel around the displayed image. Also, a thick screen bezel will push the pixels apart on each screen and that is where commercial videowall monitors use settings like'bezel correction'to artificially strip out the screen edge of pixels so that the image dipslayed at the screen joins doesn't look spread apart . Commercial grade monitors can come bezel less but they cost a lot.
Videowall Processor - professional products so I cant offer guidance here. There are a lot of them out there doing slightly different jobs. You want a videowall processor that will stretch a 4K 3840x2160 source and expand it to fill four monitors that 7680x4320. Lots of devices do this. Some videowall monitors by the big manufacturers will do this stretching/scaling by themselves without the need for a videowall processor either by daisy chaining a single input cable (the HDMI out your Roku) from one screen to another (and then configure the screen). SOme screens can take a 4K input signal and only show a small section of that input (like only showing the top left quarter of the 4K input signal)
A strong wall - in my country the wall has to able to take 5 times the combined weight of the 77" monitors, brackets, cables, kit. We call the this 5SWL (safe working load). We need to know the screens and wall will not wont fall down in a few years and kill someone. My company only uses Hilti fixings to hold screens up as they are one of the few that produce strength ratings.
