Posted October 23, 2022 I currently have a GTX 1080 and my new monitor (ASUS PG42UQ) will probably be getting here before all my new PC parts arrive. I'm just wondering if it would be possible for me to at least plug in the new monitor on my current PC to make sure it doesn't have any defects. Apparently the GTX 1080 is DP 1.2/3 (?) but the new monitor is DP 1.4. https://pcpartpicker.com/b/DYNPxr Link to comment Share on other sites More sharing options...

Posted October 23, 2022 It'll work, you just won't be able to run the monitor at 4K 144Hz without things like chroma subsampling. If you stick to 4K60 you should have no problem (IIRC 4K120 should work without chroma subsampling, but not as confident on that. Link to comment Share on other sites More sharing options...

Posted October 23, 2022 I have. It does. Still not as good as the HDMI 2.0 slot. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

I thought DP was recommended over HDMI for computers. https://pcpartpicker.com/b/DYNPxr Link to comment Share on other sites More sharing options...

Posted October 23, 2022 DP has several inherent drawbacks, from what I've read. Monitor sleep tends to either not work or do wonky things with DP. So unless there's a DP interface that offers superior refresh or other advantages--I would default to using HDMI every time. Link to comment Share on other sites More sharing options...

I thought DP was recommended over HDMI for computers. dp1.4 works with 4k 120hz sdr or 4k 100hz hdr without subsampling, hdmi 2.0 is 4k 60hz iirc, could be wrong on this one, been awhile. if you have no other monitors connected and, i'd use dp. if you have another monitor via dp to ur gpu, i'd use hdmi. Weird disconnects can happen with 2 dp monitors on sleep. 5950x 1.33v 5.05 4.5 88C 195w ll R20 12k ll drp4 ll x570 dark hero ll gskill 4x8gb 3666 14-14-14-32-320-24-2T (zen trfc) 1.45v 45C 1.15v soc ll 6950xt gaming x trio 325w 60C ll samsung 970 500gb nvme os ll sandisk 4tb ssd ll 6x nf12/14 ippc fans ll tt gt10 case ll evga g2 1300w ll w10 pro ll 34GN850B ll AW3423DW 9900k 1.36v 5.1avx 4.9ring 85C 195w (daily) 1.02v 4.3ghz 80w 50C R20 temps score=5500 ll D15 ll Z390 taichi ult 1.60 bios ll gskill 4x8gb 14-14-14-30-280-20 ddr3666bdie 1.45v 45C 1.22sa/1.18 io ll EVGA 30 non90 tie ftw3 1920//10000 0.85v 300w 71C ll 6x nf14 ippc 2000rpm ll 500gb nvme 970 evo ll l sandisk 4tb sata ssd +4tb exssd backup ll 2x 500gb samsung 970 evo raid 0 llCorsair graphite 780T ll EVGA P2 1200w ll w10p ll NEC PA241w ll pa32ucg-k prebuilt 5800 stock ll 2x8gb ddr4 cl17 3466 ll oem 3080 0.85v 1890//10000 290w 74C ll 27gl850b ll pa272w ll w11 Link to comment Share on other sites More sharing options...

Posted October 23, 2022 GTX 1080 supports DP 1.4 HBR3 but not DSC. Therefore it can achieve 4K 120 Hz 8 bpc. Higher will require chroma subsampling. Newer graphics cards can use DSC to achieve 144 Hz and 10 bpc color depth without chroma subsampling. When powering off a DP monitor with the power button, most monitors are configured such that it is seen as a disconnect event. This means if you have a multi-monitor setup, your windows/desktop icons will be rearranged onto your remaining monitors. This behavior will depend on exactly how the monitor is designed, however it is quite common for DisplayPort and quite uncommon with HDMI except on TVs.
