TV or Projector for work

 The video projector at work blew up.  Literally. The bulb (I assume) when bang and what a bang it was.  Exploded.
4k is  3,840 x 2,160 pixels
I think UHD means 4k.  Kind of a consumerisation. 
UHD technically is 3,840 x 2,160 pixels while 4k is 4,096 by 2,160 but it seems the consumer UHD products are marketed as 4k

QLED is just a LCD with some enhancement.  It's not OLED.
OLED is an invividual LED per pixel
ULED is ??? Still has a back light

Samsung Crystal UHD - its a processor chip rather than a display technology.

9-11-2022 UPDATE - INSTALLATION

I figured I would engage in a bit of practical work (read displacement activity) and hang it on the wall myself.  

It's a metal frame gyproc wall and I wanted the bracket to be supported across 3 studs. Couldn't buy a long enough one so I bought two and joined them together. 

Interestingly the bracket I'd bought with it from JB HIFI, whilst labelled "tilt" was not tiltable in that you'd expect to be able to tilt after installation.  Went and had a look and bought the bunnings bracket.  You know how you look up and down the idle and subtly dismantle the package in store.   It is a neat piece of design and most importantly allows you to adjust angle after the TV is hung on the wall.

MICROSOFT 4k WIRELESS ADAPTER ISSUE

Wireless Display Adapter

Question

0 Views | Last updated November 8, 2022

I have a Microsoft Wireless Display adapter
Firmware version: 3.9520.47
Plugged into a 4K Hisense TV HDMI port.

When I switch the TV to that HDMI port it says the connection is 3840x2160P as expected.
It also says 8bit BT2020 16:9 YUV444HDR10

BUT some detail is missing. Most noticeable is if I bring up a Excel spreadsheet, the little thin grey lines between the cells are not displayed.

Other greys are missing too.

If I connect from my laptop to the TV by an HDMI cable the picture is perfect - The thin lines are present and the light grey areas are light grey not white.

I have tried a second 4k TV and the problem is there too and have also tried several laptops some win 10 and some win 11

I have tried duplicated displays and expended display.

It seems pretty conclusive that it is the adapter.

It feels like some kind of auto scaling issue that is dropping some information.

Any suggestions as to why the problem is happening and how to fix it.

===========================

Below are some pictures. The top two pictures show the difference between using a cable and the wireless adapter.

An interesting update. While I was taking these photos, I was connected to the TV using the Microsoft wireless adapter and I brought up the display settings window and suddenly observed that just to the left of that window, the thin excel lines are visible.

It seems to me that the problem is that the Microsoft adapter is misinterpreting the brightness information. It's akin to washing out.
