When deciding between the new OLED or the old LCD, hmm, decisions, decisions.
Did you get one in the end? I was having this same conundrum last week, then found out there is a new one coming out in 2025/26, so only a year or 2 away, which swayed me towards grabbing a cheap 2nd hand LCD as a good way of gauging how much I'd actually use it, and then upgrade to OLED/Steam Deck 2 in a couple of years if I got good use out of it.
I ended up with a 512GB with the etched/anti-glare glass, and at first I was a bit unsure after reading some reports of washed out colours/glow etc., but either I got lucky, or those reports were massively exaggerated (probably the latter given how much people like to moan on the internet
). Having used it in person, I have no regrets, the screen is easily vibrant and bright enough to use even in a brightly lit room (obviously given the time of year I haven't tried it outside in the sun), and this is coming from an AW3423DW as my daily use desktop monitor, so not like I'm comparing it to a crappy budget screen!
Sure the OLED is going to be better, and side by side, I'm sure the difference would be noticeable, but it's not like I bought it for cutting edge graphics anyway - that's what my PC is for!
If the choice was between a new 256GB LCD @ £350 or the 512GB OLED @ £480 then I probably would have gone for the OLED (even if just for the bigger storage - upgrading the LCD with a 512GB/1TB NVME is going to take a decent chunk of that £130 "saving" anyway), but given I paid just over half the price (£260) for my 2nd hand one, I don't think the extra £220 would have been worth it in my case.
