Looking to buy oled, 4K monitor for gaming and viewing sky uhd, 4k

[Tony7]

I’m currently using an old 4K monitor it only displays 4K @60hz I would like hdmi 2.1, 4K, 120hz, hdr 10 for console gaming and viewing sky uhd and 4K content as my current monitor can’t do that
I live with my who is 89 she watches her italian content that’s why I use monitor so can keep her company while doing things I enjoy rather than get a tv and game in another room

for gaming is oled the best and any chance static images can burn into the screen like tvs? I’m prepared to spend around £1200 I sit close to my monitor when gaming but around 7 feet away when viewing tv. I rather buy a momitor and spend time with mum but could keep this monitor and game on a tv in another room when she sleeps as she sleeps a lot but like monitors as they lag is low and thought monitors were best for gaming.
thanks in advance for your help

Is 42" too big? Its the smallest tv that can be used as a monitor. LG C2.

42” is fine. I would like something 32” to 42” as I find 28’ is quite small something bigger would be better for gaming experience i think

Got to be the 42" c2. Had mine for a few weeks and loving it. It's great as a monitor and as a TV. Plus it's sub £1000 now.

Thank you. I think will treat myself to one for Christmas unless see a great deal in the Black Friday sale. I will use it mainly for gaming but will watch uhd sky and streaming services
