Monitor suggestions

[Per E. Johannessen]

Hi,

I'm planning to purchase a new monior, minimum 32 inches, must have DP and/or HDMI.
Noticed that there are lots of relatively cheap 60 Hz available, what's the minimum "good" Hz these days?

Any recommendations?

Hi Per

I am pleased with the Dell p2222h monitor I bought a few months back so am happy to suggest Dell as a brand - possibly this may be of interest  https://www.dell.com/en-uk/shop/dell-32-4k-uhd-gaming-monitor-g3223q/apd/210-bdxs/monitors-monitor-accessories

The monitor and your display hardware will negotiate to offer a set of display resolutions. It's difficult to predict what that set might be. You may want to try several monitors with your hardware and buy the best one.

Per,

What is the functionality you are specifically looking for, if any?

Here is what I mean:

1) if you want high-quality colour reproduction, you'd want something that covers a wide colour spectrum, there are specific ratings for this (CG, CIE1976 Colour Gamut, etc.), luminance or viewing angles

2) if you want a general 'home computing' display, I would suggest you look for something with a good contrast, wide viewing angle and good colour gamut

Refresh rate on the other hand, we are talking the gaming monitors type stuff is all tied to actual game FPS ratings and therefore things like response time become extremely important.

[Per E. Johannessen]

The monitor will be used for gaming (Win) and office-apps (AOS) so most likely it will be a "gaming-monitor".
At the moment I'm using a Radeon RX 580 and it has worked fine for years with my 13 years old monitor, 27 inches, 60 Hz, 1920c1080.
This GPU is now showing signs of "giving up", so I'm going to replace both GPU and monitor.

However, I've just tried a Radeon RX 7800 XT with the same monitor and have some issues;
Sometimes when I switch on the pc I only get a black screen.
Other times I get to the Lenovo splash screen (and can enter BIOS) and after the splash screen it goes black.
And then there are times it boots ok, get to the Airboot menu and can boot AOS or Win.
If I reboot from AOS or Win I randomly get one of the above mentioned scenarios.

I bought new DP and HDMI cables, not cheap ones, and have the same result whether using DP or HDMI.
Any suggestions for quality cables?

Hi Per

The issues with the rx 7800xt are more likely to be a graphics card failing than cheap/dodgy cables.

You could check that the graphics card is seated in slot correctly.

Hi Pete,

I have checked that the card was properly seated several times, also tried different slots.
A friend of mine checked it in his computer and the card worked fine there.
I opened a ticket in a Lenovo forum and hopefully someone comes up with a solution.

If not, I'll get a new GPU, any recommendations for one with minimum 12G RAM?

[Pete]

Hi Per

I seem to recall reading somewhere that some recent/current graphics cards will only work properly with a UEFI bios. Cannot find where I read that though to double check...

If the above is right are you using the rx 7800xt with a UEFI system?

No, Sorry, cannot recommend any particular current graphics card.

[Per E. Johannessen]

I was wondering about that as well and asked Sapphire, they replied: This model is hybrid bios support both Legacy/ UEFI mode, no worry for this.

Hi Per

A few years back I had a monitor that was failing. Sometimes at Power On I had a blank screen other times the screen was a "white out". This happened less often during reboots.

I initially thought the graphics card was failing but that tested OK in 2 other systems. I then swapped monitors and the problem moved to the system that I had swapped monitors with. Turned out to be a power supply intermittently failing in the monitor.

Could it be the monitor rather than the RX 580 graphics card 'showing signs of "giving up"'?

Hi Pete,

I've actually tried another monitor and the results are the same.
As you've mentioned before it could be that the card is not seated properly although each time it feels like it is correctly in place.
Think I'll try some cleaning of the slots and give it another try.

[Dave Yeo]

Another possibility is the power supply not being powerful enough or starting to fail. Some of these graphic cards eat a lot of power.

[Per E. Johannessen]

The PSU is 900W. If it's starting to fail I'd believe that the other GPU (RX580) also would be unstable, (although it is less power hungry).

I have, once again, tried the RX 7800 and I'm sure it was properly seated. Power and DP also properly connected. It still behaves as before.

I find it strange that there is so much problems with OS/2 video.  I have a dell 30inch 2560x1600 monitor that runs without any problem.  No problem with video cards, I don't have one, it runs from the built in video of the Ryzen 3 processor.

[Per E. Johannessen]

It is not a problem with OS/2 video, same trouble with Win, like I mentioned:
---
Sometimes when I switch on the pc I only get a black screen.
Other times I get to the Lenovo splash screen (and can enter BIOS) and after the splash screen it goes black.
And then there are times it boots ok, get to the Airboot menu and can boot AOS or Win.
If I reboot from AOS or Win I randomly get one of the above mentioned scenarios.

For some reason this specific GPU will not work reliably with the ThinkStation P520 and Lenovo seems to be out of ideas.
(In another pc the GPU works fine.)
