A huge thank you for this reply!
A few points:
- I thought the Dell was 5ms response time? This seems normal for IPS panels and something I am used to, so that's no issue.
- The LG is considerably more expensive than the Dell (£110) which would make it a £350 jump in price, I think I'd be calling myself crazy at that point.
- The real estate would actually be a drop down for me, going from 3840x2160 down to 3440x1440, but I don't think that's going to matter much to me, I find it a struggle to use all my monitor during day to day use as it is.
As for G-Sync and 144Hz, it's something I have never tried which means I have never experienced it, so I'm not sure if they're just bells and whistles that I won't enjoy. I wish there was a type of try-at-home monitor service where I wouldn't have to send them back under DSR or anything!
I've gamed on 60Hz for my entire life, I can't say I have ever noticed a lack of clarity/smoothness or anything along those lines.
Ah well, it's either the RoG Swift or the Dell U3415W, I'm scared of not having enough monitor space so I think I'm going to sway towards the latter
