I believe he was running at 5120x2880.
I've yet to see any success at 2560x1440 @60hz.
Got a tip for us?

I believe he was running at 5120x2880.
I've yet to see any success at 2560x1440 @60hz.
I have a Dell U2518D and it still pulls 18W in clamshell mode. 2560*1440 @60 HZ with HDMI cable connecting through the Twelve South StayGo hub. My usb-c to hdmi and usb-c to DP cables are on the way, and will test if that makes a difference.
@Spartan23R
I wonder if this has something to do with AMD FreeSync that the 29UM69G-B seems to support.
For the record, it appears that "AMD FreeSync™" is implemented using "Adaptive-Sync" that requires HDMI 2.1 or at least Display Port 1.2a support to work (we'll need supporting monitor, GPU and the right connecting cables supporting one of these standards between the laptop and monitor).
@Spartan23R
Could you please confirm the cable you are using to connect your MBP-2019 to your 29UM69G-B? If possible please post a picture.
Thanks a lot.

Yes please keep us updated. I'm interested to see how you get on. Maybe HMDI 2.0 vs 1.4 or DP will make the difference..
>> I have a Dell U2518D and it still pulls 18W in clamshell mode.
This is unexpected. I consistently get ~6-7 W in Dell P2415Q at higher resolution.
>> 2560*1440 @60 HZ with HDMI cable connecting through the Twelve South StayGo hub.
Note that the "Twelve South StayGo hub" only seems to support "Crystal clear 4K x 2k @ 30Hz HDMI / Full 1080p" (not 60 Hz).
Thanks.
Either you've cracked the code or the fans just haven't started yet..
Yeah but the display shows it's running at 60hz, and I've seen other people reporting clamshell still heats up at 2560*1440. Also interestingly, if I change resolution to 1080P, it only pulls 6~7W as you observed on your 4k monitor. Pics below, but I think it might worth for you to change resolution to 1440 and see how it impacts the GPU power.

Just coming back to this. Another user here has the Dell U2719dc running at 2560x1440 @60HZ. Same issues with USB C - DP
.I think at this point I'm ready write off 2560x1440 @60hz monitors. Seems to be mostly Dells.
The question now is whether our money is best spent on new monitors or an eGpu setup which will (possibly) give us back use of our internal screens too.
This is only 1080p..
I think all of the "behaving" monitors in this thread have FreeSync.
resolution external screen 2560x1080, internal screen scaled to 'more space' 2048x1280 (normal usage, browsing, mail, streaming, time machine backup), the 16-incher is silent.
Fans speeding up when working in apps like lightroom or final cut, but not overdrive speeds like gaming in bootcamp. I've mostly music on or noise cancellation headphones, so the fan noise doesn't really bother me, rather have a cool system.

Fan noise isn't the issue, everyones environment will be different which will change "fan noise". Issue is the ridiculous power consumption of the GPU. 19w. At idle. Why?
@Spartan23R
Thanks for sharing the details above.
- Could you please post another screenshot that shows your fans' RPM readings?
- Do you use custom fan profiles (example here)?
Please note that your "Radeon High Side" reading is ~19-20 W which is what the rest of us are complaining about - prolonged use with ~19-20 W Radeon dGPU in open-lid mode easily drives the fans to ~4200-4500 RPM.
Thank you.

I played around a bit more with the resolution settings on my Dell P2415Q following your reply. Please note that the following results are with 30 Hz, Retina (2x), and in clamshell mode. My 2015 model P2415Q doesn't have HDMI 2.0 - so no 60 Hz for me over HDMI.
- 2560 x 1440 @30 Hz actually draws ~19-20 W on my Dell P2415Q too - this was rather unexpected for me.
- 2560 x 1440 @24/25 Hz draws ~6-7 W for me.
- 3840 x 2160 @30 Hz draws ~6-7 W (previous result posted here).
I have noticed that after changing to a 30/25/24 Hz resolution in EasyRes, if I change "Scaled" resolutions with Mac's display preference, it will switch resolution, but not refresh rate e.g. change from "Default" to "More Space" in Catalina system preferences, and then crosscheck in EasyRes, you'll notice that the upper/lower resolution has been selected but the previously selected refresh rate persists.
Secondly, it takes a little while for "Radeon High Side" to drop from 19 W to 6 W e.g. waiting around 1 minute has been sufficient for me.
Hope this helps. Thanks.
This is very helpful and it definitely seems like a drive issue to me if 4K @30 hz in clamshell draws less watt than 2K @30 hz with the same monitor... Hope there is a way Apple recognize this and actually fix it...
Updated clamshell info.
2560x1440 @60hz or 30hz is a problem even in clamshell mode. Can currently only be fixed if your monitor can support higher or lower refresh rates @themcfly confirmed this earlier in the thread on his own setup but I think at this point there's enough supporting evidence from others.
Connection method does not seem to make any difference unless it opens up extra working resolutions/refresh rates.
For the most part most gaming or modern monitors outside of the Dell U-Series have some sort of variable or higher than 60hz refresh rate. I believe Freesync allows this so that may be something to look for.
If anyone has found any other problematic combinations please post them. I believe there are a few other "bad" configurations.
Possibly running 2 monitors with different refresh rates could cause issues even if fine by themselves. I've seen at least one post that would suggest this.

USB-C to HDMI connection.
@85Hz Radeon High Side spikes to 19W.
Yes, looks like dropping the refresh rate down helps. I tried dropping down to 60 Hz and it goes back down to 6-7W. Resolution is 3840x1600.
@caupljx @Grammar1
# CLAMSHELL MODE
I repeated the clamshell-mode tests posted here today again, and can confirm that "3840 x 2160 @30 Hz" works for me in clamshell-mode (Radeon draws ~6-7 W), and "2560 x 1440 @30 Hz" does _not_ (Radeon draws ~19-20 W). I don't know how to explain this.
Thanks for aggregating the _clamshell_ mode results here for different monitors.
# OPEN-LID MODE
I'd just like to repeat that the "open-lid" mode continues to force Radeon to draw ~19-20 W irrespective of any monitor, resolution, refresh rate, or connector combination.
Thank you.
Hi Everyone,
In case you are doing the resolution test with your MBP-2019, and want to contribute with your results, please have a look a the following:
# STEPS FOR TESTING
P.S.
If you feel that we need to collect more information in the table, please drop me a line - I'll revise the template above. Alternatively, please feel free to post a revised table in your reply. Thanks a lot!
In case you are doing the resolution test with your MBP-2019, and want to contribute with your results, please have a look a the following:
# STEPS FOR TESTING
- Start your MBP-2019 in open-lid mode.
- Make sure you have the charging cable connected to the MBP-2019.
- Otherwise, if you are testing for the "clamshell" mode, it will put the laptop into "sleep", even when using tools like "caffinate".
- Connect your external display using Thunderbolt, HDMI or DisplayPort Cables. Turn on your monitor.
- Once the resolution, refresh-rate and application windows on both the MBP-2019 display and on your external display(s) are settled, you are ready to play around with the resolution and refresh-rate settings.
- Please use a tool that shows both the resolution, refresh rate, Retina/Non-Retina status etc. for your monitor. EasyRes is one such free tool.
- To collect the readings on "Radeon High Side", use iStat-Menus.
- Select a resolution and refresh-rate combination from EasyRes.
- When switching resolution, refresh-rates etc. in EasyRes, the "Radeon High Side" reading is likely to temporarily jump high, and may even reach up to ~20-22 W.
- Wait at least 60-90 seconds before taking your last reading on "Radeon High Side".
- Screenshots are great and everyone loves them!
- Check the "Radeon High Side" temperature graph in iStat-Menus to collect your last reading.
- Good results are known to be around ~6-7 W.
- Bad results are known to be around ~19-20 W.
- Please use the following table when adding your results.
- If you are on desktop Firefox/Safari/Chrome, you can copy-paste the whole table and only edit the relevant parts to you (select from "Macbook model" until the last row last column, copy-paste, leave column-1 alone, and revise your column-2).
| Macbook model | - Example: MacBook Pro (16-inch, 2019) - Menu-bar > About This Mac |
| dGPU (PCIe) model | - Example: Radeon Pro 5500 - Menu-bar > About This Mac > System Information > Graphics/Displays |
| MacOS version | - Example: Catalina 10.15.4 (19E266) - Menu-bar > About This Mac |
| External display - model | - Example: Dell P2415Q (2015 model) |
| External display - resolution and refresh-rate | - Example: 3840 x 2160 @30 Hz (Retina 2x) - Use EasyRes for this |
| Internal (MBP) display - resolution and refresh rate | - Example: 2048 x 1280 @ 60Hz (Retina 2x) - Use EasyRes for this |
| "Radeon High Side" power consumption | - ~19-20 W - Use iStat-Menus for this |
| Internal (MBP) display mode when doing the test | - Open-lid (or Clamshell) - Example here. |

I just got a MSI MAG272QR and having the same problem.
2560 x 1440 at 60 Hz, Radeon draws 19W even in clamshell mode
You need to change the refresh rate.. this monitor has Freesync and it's native is 165Hz so you should have some options.

I double-checked the _working_ monitors from your list above (table below).
I get the feeling that these issues are not exactly related to FreeSync (or NVIDIA's G-Sync) as we speculated previously. Note that the Radeon 5300/5500 are unlikely to support G-Sync from the GPU side.
Also, @Spartan23R's results here confirm that Radeon is drawing ~19-20 W for him in open-lid mode (with 29UM69G-B monitor). This is same as the other previous results in open-lid mode.
Hope this helps. Thanks.

I did some testing with EasyRes on my LG 4K 27UL850-W, connected with a usb-c to usb-c Cable. (clamshell mode)
For some reason I had 3 options of the problematic resolution of 2560x1440 in the "Standard (x1)" category, two options with 60hz and one with 30hz.
-2560x1440 60hz: Worked fine, 4,3-5W idle (System Report showed 2560x1440 @60Hz)
-2560x1440 60hz: Resulted in 18W Radeon High Side (System Report showed 2560x1440 @59Hz)
-2560x1440 30hz: Worked fine, 3,8-5W idle (System Report showed 2560x1440 @30Hz)
So maybe those of you that have problems running 2560x1440 monitors actually use 59Hz instead of 60Hz?
Please double check in System Report and always close and reopen it after a resolution change, it will not refresh by itself.
Edit: Connection type is called "Thunderbolt/Displayport" in System Report.

Yes I think FreeSyncs's only part in this is that it's signifies a choice of refresh rates. Hopefully allowing you to find one that works well. I don't think it has anything to do with open lid mode being broken. I think that's down to AMDs drivers so nothing we can do there.
[automerge]1585475977[/automerge]
That is very interesting and adds another variable to this. Are you able to screenshot that for us? Mine is definitely at 60Hz so there must be something else at play here.

Unfortunately I don't have an external Keyboard with me at the moment, therefore taking screenshots is not that easy.
But I will post some as soon as I can. (I use a mouse to change the resolutions in clamshell mode)
Another interesting find: while using a usb-c to HDMI cable with the same Lg monitor as mentioned above, I get some different numbers. (again tested in Clamshell mode)
There are 5 Options of 2560x1440 in "Standard (x1)" of EasyRes, one with 60hz, 50hz, 30hz, 25hz, 24hz
-2560x1440 60hz: Resulted in 18W Radeon High Side (System Report showed 2560x1440 @60Hz)
-2560x1440 50hz,30hz,25hz,24hz: all worked fine 4-5W (System Report showed the same in all cases)
Typ of connection shown by System Report: "DVI or HDMI"
-3840x2160 with usb-c to hdmi: same 5 different refresh rates, all worked fine 5-6W
-3840x2160 with usb-c to usb-c: 60hz and 30hz both work fine 5-6W
edit: conclusion for 2560x1440 60hz: in my case Displayport/(usb-c) connection seems to work ok 4-5W, HDMI connection results in 18W Radeon High side.
I also started to report the problem directly to AMD since they are the manufacturer and this could very well be a GPU Driver/Bios sided problem by them.
I guess they provide the driver and apple tinkers around with them a little more (im not an expert on this topic as can be seen).
It is such a shame because this is the only issue (at least for me), that ruins an otherwise awesome user experience.
Lets just hope we get a fix soon!
