My Lg 65 can be mounted on the lower edge 70 cm from the floor

The TV mount "105209 Fixed universal stand mount for TV-LCD (65", 35 kg)" from Techly is compatible with VESA mounting holes at a distance of 200 x 200 mm to 600 x 400 mm. Your Philips 43PUS8555/12 TV also has VESA mounting holes, and since 200 x 200 mm is within the supported range, the mount is not too small for your TV. The mount should be compatible with your TV without any problems.

I think it works with any flat screen TV. Ultimately, it's about the TV having threaded screw holes on the back.

No I cannot, but for sure additional 3 kg should not be a problem. It is a steady stand.

If your Samsung has VESA then yes. I think it's standard either way. VESA 200 x 200 mm or 600 x 400 mm

The stand has enough mounting holes. Adjustable in height. The frame has a mounting grid of 400x300mm, so yes, it should fit.

If the TV has 4 threaded sleeves (VESA standard) on the back it will pretty much work. The bracket is very flexible in mounting.

Yes it works! I was able to install my Sonos beam with an additional part. conecto CC50650 Bracket for direct mounting on the TV, compatible with SONOS Beam Soundbar, load capacity: 5kg, black https://amzn.eu/d/cQBXjrz

No

No, this stand is only for models up to 65''. I have gladly linked you to the matching TV stands for your The Frame 75''. https://www.digitec.ch/de/s1/producttype/tv-staender-525?filter=nr_19290%3D1.9050000000000005%3A2.857500000000001%2Cnr_2940%3D50000%3A500000%2Ct_841%3D1584&tagIds=538-540

I don't know the Samsung frame, but I would say that if the 35kg is not exceeded - no problem. The stand supports my 65" Samsung display.

The bigger the screen, the better. Hundreds of screws are supplied, but I had to go to a specialist shop to get the appropriate screws, size and correct length plus washers. No problem with the frame!

The bracket is compatible with TVs with a maximum VESA 600 x 400, but the mount is intended for TVs between 45" to 65" and not smaller.

You must look at weight. If there is any problem, they don't answer. They let me down (for your info).

Yes and no. If it is not clear, it is normal. There is a set of plastic shims that are supplied along with the screws. They are used to compensate for the slope. In my case, my curved TV also had mounting wedges for flat mounting.

According to the supplier, if the TV set is equipped with a Vesa mount and is of a suitable weight and size, it should be compatible. The basic requirements are - Maximum load of 35 kg - Max. size TV size 65 - Wall mount type VESA 600 x 400 mm

According to research, this stand is only suitable for TVs from 45" to 65".
