Likely Apple was kind enough to give you a display color set that isn't as harsh on the eyes. Just change it back… It's not anything the monitor itself is doing.

Yeah, USB-C is unlikely to work on a desktop. Just use DP instead of HDMI to get the higher refresh rates.

Since the spec on that TXZAA has it able to run the 1440 at 240Hz, it has to be DP 1.4, 1.2 can't handle that bandwidth. I'm guessing there's a bug in the OSD if it's saying 1.2 only.

Typically Nvidia numbers their products with xxy0, where xx is the generation and y is the performance level within that generation. So, a 770 is 7th gen level 7. The higher the level, the more power needed to drive it. A 1030 (10th gen, level 3) would easily run on your 300W, as would a 1050. Look for the newest one you…

I do not see a TCC-855 model, or a TC-855, but there is a TC-865. The D17E5 doesn't tell us anything, since they don't provide us with any sort of cross reference, and they apparently reuse those "model numbers" for different series of systems. Your full model number is usually on the same sticker as your serial number, it…

They spec 4800, but used 5600 instead on the later builds, due to supply line issues with the slower speed. They all run at the speed the chipset supports, 4800 MT/s.

Yes. If there aren't holes for mounting the 2.5" SSD, just use an adapter. IIRC there are holes, they are just sideways from what you expect…

There is no ECC support on the motherboard. VT-d is enabled in the BIOS under Advanced; CPU and Chipset, but just called Intel VT.

When searching on Acer sites, be sure to use TC-1775. The dash is important or else the searches will fail. Here are the modules that Acer shows in their service guide: Although I believe at least some of them shipped with DDR5 5600 rather than 4800, due to availability issues with the 4800. Either way they run at the 4800…

Nope, your XC-1780 uses an ATX12VO type power supply and the old school ATX supplies won't work without a custom adapter cable. You have a 6 pin main power connector on the motherboard, and that supply uses a 24 pin instead. There are four connectors on your motherboard that would need to be dealt with, the ATX12VO main…

Intel just changed the name from IRST to VMD in 2020. They didn't stop support for it…

Nope, not without building some custom adapter cables: An ATX12VO supply only provides 12V DC and on an Acer does it with a 6 pin connector, instead of the 20+4 connector that supply has.

The servers for those products were retired several years ago, so they are no longer really usable.

There was a BIOS update release in December for the PO5-655 models, and a Predator Sense update in September. Are you up to date with both of those?

OK, which BIOS version is installed and which version of Predator Sense?

The user interface and features for Predator Sense are different for different Predator models. On my PO5-640 there are three different fan modes shown: In auto the fans tend to remain quiet, in gaming they get a lot faster and louder, in custom I can set them to run at various percentages of the automatic speeds or run…

Needless to say, if your PC is old enough to require a FAT32 format it's too old to run Windows 11… The key is turning on the boot menu in the BIOS. It is disabled by default. Once it's on then an F12 at boot time will give you a list of bootable devices and you can choose the Windows install flash drive. Depending on your…

There have been several BIOS versions and a couple of Predator Sense version for your PO5-650 (note PO as in Predator Orion, not P0 as in Predator Zero, Acer's search isn't smart enough to find the wrong one). Verify you are at the latest by checking the version installed against what Acer has on their support site. The…

Try it with the battery disconnected and the charger connected. See if it come up and runs in that configuration. If it does we don't have to deal with potential other issues, just a replacement battery. If it doesn't work without a battery then we don't know enough to get the full root cause. :(

Thanks for that info, it sounds as if you are right and it's a bug in the implementation of multiple desktops, they should start the second desktop with some of the same settings as the original, rather than with the defaults.
