Is G-Sync really necessary with a 4K monitor ?

[mms123]

Hi everyone ,
We have seen Asus announcment about new first 4k gaming monitor 144hz with
G-Sync + HDR + ips . i think Asus PG27UQ will cost almost 1500$ and i can't afford it .

So i can't decide between 1) Acer XB321HK 4k G-Sync + ips
or upcoming Lg 32ud99 4k HDR + ips without G-Sync .
What is the most important thing between (G-Sync and HDR ) ?
Can i play with lg 32ud99 with upcoming nvidia gpus sush as volta with smooth gameplay
at 4k without having to G-Sync
or G-Sync is worth it with 4k ips 60hz than HDR ?

thanks in advance

1. It's nice to see DP 1.4 capable monitors arrive ... however that is bad news for those who just bought 4k monitors as the value of those is going to tank on the resale market.

2. No, in this size range, I would not use a monitor without G-Sync and ULMB .... nor would I use a 4k monitor at 60 Hz.

3. The availability of 144 hz @ 2160p is hampered to the extent that there are no cards which "can take you there".... many of today's games are stuck below 60 fps at 4k w/ a AIB 1080. A total of 10 of the 16 games in techpowerup's gaming test suite can't hit 60 fps at 4k. So I really don't see the attraction of 4K @ 144 hz ... if there's no GFX card that can deliver it. Even two in SLI can't break 60 fps in 3 of them.

In short, I find it hard to spring for the big bucks when, at this time, we can't truly take advantage of the technology. I'd rather play at 1440p ... w/ Gync in this rare instances when fps is < 70 fps and w/ ULMB when it's above that. Then again, if ya have the disposable income available to spring for the screen, then twin 1080 Tis should be able to drive it.

If ya not willing to throw $3k at it, then the best experience available right now is XB271 HU or Asus PG279Q

Thnks bro
I think upcoming nvidia gpus in the near future will be hit 4k above 60fps so in my opinion G-sync is a temporary solution for current gpus .
I think upcoming generations from nvidia will be overkill to 4k 60hz so maybe don't notice G-sync above 60 fps .
I agree with u if the monitor up to 120hz or 144hz such as Asus PG27UQ , in this case surely we will need G-sync .

You don't use G-Sync above 60 fps ... you switch to the ULMB option.

- From 30 - 70 fps, G-sync provides a significant improvement
- From 40 - 70 fps FreeSync provides a significant improvement
- When above 70 fps, with nVidia cards you can turn off G-Sync and use ULMB which provides significant improvement
- When above 70 fps, with AMD cards there is no comparable option, tho some manufacturers include their own MBR technology. ULMB which provided significant improvement
