Need recommendations for 30,30+" display with 144hz refresh rates & 2k resolution in minimal prices.
Dont want 4k resolution as i dont want to stress up my gpu on higher resolution.
I checked various online websites but couldnt find availbilty of listed models.
Max budget is around 70-80K.

Thanx for response as i already bought Gigabyte G32 QCa @ 71500..
Now im confused in choosing which cable/port should i use...
So, which cable should i use for 2560x1440 resolution
HDMI 2.0 or Display port 1.2

(GPU hav HDMI 2.1 & DP1.4 but monitor has HDMI 2.0 or Display port 1.2 limitations)

AOA, that's an excellent question, short answer: always prefer DP over HDMI if both devices have a DP because within the same generation, DP has always had more bandwidth than HDMI.

Long answer: well we can calculate data rate at the monitor's max resolution and see how much bandwidth we need to have in the medium.

Max. Data Rate Reference Table:

HDMI1.0–1.24.95 Gbps3.96 Gbps

Your monitor has a max resolution of 2560x1440 @ 165Hz and it's HDR capable.

Video Format:
2560 × 1440 (16∶9 ratio) at 165 Hz
8 bpc (24 bit/px) RGB color
Uncompressed
CVT-R2 timing format

Frame Size:
2,560 × 1,440 = 3,686,400 pixels per frame (3.7 Mpx)

Effective Frame Size with CVT-R2 Blanking Intervals:
2,640 × 1,559 = 4,115,760 pixels per frame (4.1 Mpx)

Effective Pixel Rate:
4,115,760 px per frame × 165 frames per second = 679,100,400 pixels per second

Bit Rate:
679,100,400 px/s × 24 bit/px = 16,298,409,600 bits per second (16.30 Gbit/s)

Data Rate Required: 16.30 Gbit/s

Which should work on a DisplayPort 1.2 port with at least an HBR2 rated cable. Now, at max resolution of 2560x1440 @ 165 Hz you can only use HDR with 8-bit RGB uncompressed or lower (compressed formats YCbCr).


There is an excellent guide at LTT Forums:

    You reap what you sow. This is what happens when you take away choice from consumers. Even with 88% split going to developers, they can't recoup costs. Meanwhile, Helldivers 2 is a massive hit for Sony thanks in big part to Steam.
