I summarize: I have Windows 10 Pro (64-bit) and the Microsoft Basic Display Adapter installed. Everything worked perfect, until I had to buy a new monitor: Philips 223V5LHSB2/55. The problem is that Windows doesn't show me the 1920x1080 resolution, which is recommended for my new monitor.
If I install the latest NVIDIA driver (it was built for Windows 8), the monitor works flawlessly and is set to 1920x1080 by itself (but Windows start menu and Windows settings interface are out of control, windows flicker etc).

So: if I install the NVIDIA driver, the monitor is recognized but Windows goes crazy. And if I install the Microsoft Basic Display Adapter, the operating system works perfect but the monitor doesn't offer the resolution I need, so everything looks a bit deformed.

Is there any workaround for that problem? Thank you very much in advance!
The Microsoft Basic Display Adapter driver is not meant for everyday use. It's basically a safe mode driver providing limited functionality until you can install the correct driver. If the latest NVIDIA driver isn't working correctly, then you might have a faulty GPU. Make sure you have the correct driver. If it's an older GPU, you can find Windows 10 drivers here: https://www.geforce.com/drivers/beta-legacy

Thank you very much for your answer, ToastyX! Oh, I see. Unfortunately I already tried with the latest driver released by NVIDIA for my graphics card. When installed, my new monitor resolution (1920x1080) appears, but Windows works bad, windows flicker, etc. Obviously I have a compatibility problem on my hands, a shame. Anyway I appreciate your answer, thank you very much!

RE: Custom Resolution Utility (CRU)
Hey ToastyX, thanks for CRU I've been using it since back when there was a pixel clock patcher with the overlockable Catleap screens.

I've recently got a Samsung Odyssey G9 monitor (5120x1440@240hz), and unfortunately when running the monitor at 240hz the 'Customize' option in NVCP is greyed out permanently, and what is shown in CRU for the screen makes very little sense. With this display using Display Stream Compression, is there anything CRU can do to add resolution options or adjust the VRR range? It is 'G-Sync Compatible', and many users of both the G7 and G9 have been reporting VRR flickering, but there doesn't seem to be any known fix, nor acknowledgement of the issue by Nvidia or Samsung :/

I've attached what is seen in both the 120hz and 240hz modes.

Thanks!

RE: Custom Resolution Utility (CRU)
Hello ToastyX! I connect the iiyama 34" monitor to intel HD 630 via HDMI 1.4, but I can only select the maximum resolution of 2560x1440@60. I ask for help, what specific settings need to be made to enable the resolution of 3440x1440 with the maximum possible frequency? I tried to add a custom resolution in the Intel graphics settings panel, but it didn't work. Thanks!

That monitor probably uses DisplayID at 240 Hz instead of EDID, but there are no DisplayID overrides. CRU can create an EDID override with a DisplayID extension block, but I don't know if that will work.

At 120 Hz, the "Default extension block" is actually a DisplayID extension block, but CRU can't read more than one extension block with NVIDIA because NVIDIA's driver won't provide it for some reason, so if you want to edit it, you'll have to delete the extension block and add 5120x1440 @ 120 Hz back in manually.

Intel GPUs only support less than 301 MHz pixel clock with HDMI. You'll have to add 3440x1440 @ 56 Hz.

RE: Custom Resolution Utility (CRU)
I have overclock monitor my monitor is->https://www.lg.com/in/monitors/lg-22M38H# with custom resolution utility and i don't know how to back to default my monitor support only 60hz and no 75hz i don't have display port only hdmi. So my problem is how to go my monitor back to 60hz? Here is my screenshots...

               

At the last choice extension blocks (2slots left)
CEA-861: 4 detailed resolution, 4 data blocks (HDMI) then i click edit The type is CEA-861 Detailed resolutions
1920x1080 @ 60.000 Hz (148.500 Mhz) [+/+]
1920x1080i @ 60.000 HZ (74.25 Mhz) [+/+]
1280x720 @ 60.00 hz (74.25 Mhz) [+/+]
720x480 @ 59.940 hz (27.00 Mhz) [-/-]

Data blocks
TV resolutions
Audio Formats
Speaker Setup
HDMI Support

So i have open cru now at the top left need to untick 75hz and to left as is it 60hz? Established Resolution.

Detailed Resolution need to do something else or change?

Standard Resolutions: Need To delete 75hz , 16:10 and left as is it 16:9? Or i can add standard resolution 1920x1080? or other resolutions

Extensions Block: Need to delete these resolutions?->1920x1080i @ 60.000 HZ (74.25 Mhz) [+/+]
1280x720 @ 60.00 hz (74.25 Mhz) [+/+]
720x480 @ 59.940 hz (27.00 Mhz) [-/-]

And the last step: Data Blocks
I want to delete tv resolutions audio formats and maybe speaker setup.

I tryed to make as is it but no luck i got a black screen to my pc. My monitor is 75hz and i want to go at 60 hz. Which settings must to do?

Reviews keep mentioning DP 1.2, but the AMD driver won't allow any pixel clock higher than 480 MHz! The refresh rate or resolution is not even available if its 481 mhz. This seems to imply DP 1.1a....DP 1.2 should exceed 600 mhz...
The pixel clock limit depends on the number of lanes and the DisplayPort clock speed. You need a DisplayPort 1.2 monitor to get DisplayPort 1.2 speeds.

DisplayPort 1.1 max: 4 lanes @ 270 MHz = 360 MHz (8 bpc), 480 MHz (6 bpc)
DisplayPort 1.2 max: 4 lanes @ 540 MHz = 720 MHz (8 bpc), 960 MHz (6 bpc)

I bought a Mini DisplayPort to DisplayPort v1.2 cable. At least it says it's v1.2.
Refresh rate and resolution doesn't show up in the properties if it's over 480 mHz(after I run restart64.exe, of course):

222 Hz which doesn't go over 480 mHz shows and works just fine:

I'm using this cable:

On the back of the package it lists these specifications:
Quote:Interface: DisplayPort v.1.2
Connector1: DisplayPort (male)
Connector2: Mini-DisplayPort(male)
Bandwidth: 17.28 Gbps
Dual-Mode (DP++) support: yes
Supported resolution:
Max. 3840 x 2160 at 60 Hz
Audio suppord: 8 channels, 24 bit
3D Video support: yes
HDCP support: v.1.3
Cable length: 1.8 m

I also use this MSI r9 280x video card. I'm creating custom resolution for this Benq XL2720Z monitor.

Manufacturers of all 3 things claim to support 1.2? Looks like at least one of them is lying? Is it video card or the cable? Other people managed to overclock this monitor up to 250 Hz, so it's most probably not monitor's fault. Any suggestions what to do?

That's just the maximum speed for DisplayPort 1.2, which requires HBR2 mode. The BenQ XL2720Z doesn't support HBR2 as far as I know. Going higher than 480 MHz requires YCbCr 4:2:2, but I don't know if AMD's driver has a way to do that.

Run reset-all.exe and reboot to reset the monitor back to default. I don't see anything wrong with the screen shots. They don't show an override in place, and 1920x1080 is at 60 Hz like it should be. Some monitors define 75 Hz at lower resolutions by default, so that's not a problem.
