Hi, Since this thread is started, I would like to point out that saying that display walls are only used if the data size is large is not true for everybody.
We have several use cases where having a correct rendering on the client would be helpfull : * display walls can be used for team meetings : the space is then used to have several people view the same thing, not always very big in terms of number of cells. In this case, it is very usefull to have the possibility to pick/select some part of an object, and it is very diffcult to do so with a decimated view. * we also use some tools like virtualGL that enable image-based collaboration by streaming the image of the client to a remote viewer : for instance if someone was not able to join the meeting and still want to participate and share the same view on his desktop. Sending a view of a decimated object is not very helpfull... I would vote for having the possibility to have a full-resolution view on the client, comments?

What is the setting of the "Client Collect" slider on the "Options"||"Preferences"->"Render View"->"Server"->"Tile Display Parameters" tab of the Options panel? Unless its checkbox is unchecked, ParaView either decimates the geometry before sending it to the client or if larger than the threshold, sends only bounding boxes. The reasoning being that if the rendered geometry is big enough to require a tiled display to show, a single GPU on the client is unlikely to be able to handle it a full resolution.
