A quick mini review after using this for a big part of a week.
So I was choosing between this display and the dell 2721DGFA, the difference between the two screens been dell has a better stand, no srgb, hdr400 classification, 120hz hdmi VRR support and local screen dimming.
The LG has sRGB, supports HDR still but no specification and no local dimming.
I believe I made the right choice and here are my reasons.
I got round the poor stand on the LG by just purchasing a vesa mounted custom stand.
The screen dimming on the dell, is forced on when using HDR, and has very big zones, I expect that would annoy me having discovered that both the DFC and eco mode's on the LG annoy me, thankfully I was able to turn both off.
The sRGB has proved a god send, for SDR tv content, sRGB emulation is a must in my opinion.
HDR without the high illuminance levels for me is actually fine, I have always been fine with low brightness screens, and I tried auto HDR on the Xbox, and its basically like having a really well tuned reshade profile, and that is brilliant. If I did this on the dell, I would be forced to put with the local dimming implementation it has (its not optional).
I think the position of the joystick bottom centre is perfect, less arm strain to reach it.
Also a poor mans HDR can be had on all SDR content, to achieve this, you could configure a console to use full RGB space 0-255, but keep the monitor itself on 16-235, what this will end up doing is pushing all mapping further out, its effectively a free contrast ratio boost, at the cost of colour accuracy.(this can be done on all monitors that support 0-255 which is most). Reddit has a fair few posts of people doing this because they realised the proper setting feels washed compared to it, but I wouldnt do this on HDR content, as HDR will utilise the extreme ranges without this trick. I personally dont get the comments from people who think HDR is meaningless without a high contrast screen, there is a clear benefit. There is a few who agree with me on reddit as well. So I am not alone in this, however I expect it depends on perspective, I have never had the luxury of experiencing HDR on a OLED screen so I can only compare to SDR and software HDR (reshade).
I hope this helps people decide.
