Windows 7: Display becomes cropped/smaller post boot on monitor

The monitor is self powered but the signal comes from the video card which gets it power from the power supply.
How much power that takes for the signal; I really don't know.

Still be nice to know what power supply is in the system.

This link says a 400 watt PSU is required.

Just have to wait on the OP to get back to us with answers

Thanks Brian for finding that information.

You know I like proper quality power supplies. It's just a thing with me.
Plus I try not to chase problems around just to find out that one of the basic wasn't looked at.

If you think it`s the card as you said earlier, is there anyway you can pull the card and test the problem monitor by somehow connecting it directly to the motherboard ?

Do not forget to enable the integrated graphics as I mentioned earlier.

Is this your card ?

I agree, there has to be an adjustment for that monitor in CCC.

Keep working on it, you will figure it out.

You`ve tested the monitor on other machines and it works fine, so it`s the card and software.

Personally, I`m shocked you would purchase a monitor without at least 3 video connections, but that`s not the issue here.
I'm beginning to think its the card. If I don't solve this today, I'll find a Nvidia based replacement soon and sell off the R7 240.

Actually this is not my main monitor. My main monitor was a Dell U2311HM model. Had to swap it with my wife since she says the S2340L is too high. So I just exchanged it with her. I use the monitor sometimes in portrait mode for reading pdf's. The workplace was supposed to provide her a PC, but since they are slow, I decided to buy her a work PC instead. Hence the budget monitor.

What power supply does you system have?
Every monitor you add puts a load on the video card therefor more load on the power supply.
I can see where you are coming from. The PSU is OEM-part of the Dell optiplex 780 machine. Prior to purchasing the R7 240, I check each component and used the PSU calculator so that I don't go overboard buying a high end card which is not supported. I have taken into account the SSD and the additional RAM which I placed in the PC. The computer runs fine. I am reluctant to invest more in this PC since its a work pc.

I've resorted to buying a Nvidia Geforce GT 730 1 GB DDR5 as a replacement. Will sell the R7 240 2 GB DDR3 off. Power consumption is similar so I think it will not be an issue.

It would still be nice to know the total output wattage of the PSU, Dell`s are pretty crappy PC`s in my opinion and they use crappy PSU`s.

It should be written right on the label on the PSU

Who`s brand card did you get, please post the manufacturer`s link of the exact card.

Any information on the power supply sticker would be helpful.
Watts, Amps and volts.

Dell puts the smallest spec power supply they can get away with for the hardware they installed.
The supply power supply will not have any leeway for upgrades of hardware.

So we don't guide you in the wrong direction we need the exact information we request. As precise as you can give us.

Also consider you may have more than one problem. But the first step in my opinion is a proper power supply. Power supplies are the heart of a computer.

I can't really test the HDMI/DVI socket since the motherboard comes with VGA and DP. No HDMI or DVI. Quite weird since DVI should be quite standard compared to DP. Connecting the VGA to the monitor does not help since I've tried connecting it to the VGA port on the R7. It works and scales nicely.

Dell has crappy PSU for anything not written Alienware or XPS and since I've opened and went through it, it is not really that upgradeable since everything is bolted with their card. It says it supports 500W IINM. I've taken the liberty to buy something cheap way in the capacity of the PC since it was given to me. The PC itself came with Windows Vista (which I told the IT dept to upgrade to Windows 7).

I bought this Gainward GeForce GT 730 1024MB. Since I could not find the PSU requirements on that page, I think its similar unit with this Palit.

Yes, the PSU is the most important thing.

However, since my institution is currently on a tight budget, new PC's are not been ordered to match the amount of staff. Whatever is given to staff are now recycled 5-10 year old PC. Some lucky stuff got new PC's in 2012. Some people are still happy running XP on their machines.

I have another PC which I instructed my institution to buy for viewing 3D DICOM and obj files and crunching lots of numbers. When that project is over, I will use it as my main work PC. This current Dell needs to lasts 18 months more. The PC replacement has these specs:
A Dell U2715H, to a Asus Strix 780 6GB GC
I5-4690
16 GB RAM
Win 7 64 bit
256 GB SSD
4 TB HDD
A 750W Corsair PSU.

They had cash, so I thought I'd specced the PC to match my PC at home

OK let us know how things look after you install that card and it`s drivers.

Get the latest drivers for it directly from nvidia.

Welcome to NVIDIA - World Leader in Visual Computing Technologies

DO NOT FORGET to un install the AMD drivers and software before you pull the AMD card.
